For a CO alarm or symptoms, call 911 from outside. For a gas smell, avoid flames and switches; call the gas utility or 911 from outside. Don’t re-enter until responders say it is safe.\n\n Don’t use online booking for an active emergency.\n\nOWNER SAFETY NOTICE / CHECKED SEPTEMBER 8, 2026\n\n## Have a Triangle Tube? *Check its recall status.*\n\nCertain Prestige Solo, Prestige Excellence and AERCO Esteem gas boilers are recalled for a carbon-monoxide hazard. The recall reports two deaths.\n\n### Which boilers?\n\nThe 2025 recall covers specific models made from December 2011 through April 2019. Compare your model and serial number with the official list.\n\n[Check CPSC’s model & serial list ↗](<https://www.cpsc.gov/Recalls/2025/Triangle-Tube-Recalls-Prestige-and-Aerco-Esteem-Gas-Boilers-Due-to-Carbon-Monoxide-CO-Poisoning-Hazard-Two-Deaths-Reported>)\n\n### The company closed.\n\nTriangle Tube ceased operations November 3, 2025. CPSC’s March 2026 update says the recall remedy is unavailable to people who had not already registered.\n\n**Don’t count on a new free factory repair.** Existing registrations, repair history and parts availability need individual review.\n\n[Read the manufacturer’s current notices ↗](<https://triangletube.com/products/product-recall-2025/>)\n\n### What should an owner do now?\n\nCompare the model and serial number with the recall list, follow CPSC’s alarm guidance and arrange professional service for an affected unit. Keep earlier recall and repair paperwork for the technician. Leave the boiler’s safety controls intact and stop repeated resets if it fails to light.\n\nTriangle Tube also has older recall notices.

Pick the closest symptom.\n\n### No heat anywhere\n\n### Is the boiler unable to make heat—or unable to move it?\n\n#### Useful things to tell us\n\nLook at the thermostat’s normal display and the boiler’s visible error code. Note whether hot water at the taps still works. Don’t open covers or keep resetting a safety shutdown, sometimes called a lockout.\n\n#### What we check and why\n\nWe follow the heating sequence: the thermostat requests heat, the burner lights, the pump circulates water, and the floor or radiator warms the room. Checking each step shows where heat delivery breaks down.\n\n### One room or area stays cold\n\n### Start with the pipes and controls serving that room.\n\n#### Useful things to tell us\n\nTell us which rooms are cold and whether the others heat normally. Note gurgling, a recent repair, or a thermostat change.\n\n#### What we check and why\n\nA zone is a room or group of rooms controlled together. We check its thermostat, water valve and pump, then look for trapped air. We also check whether enough water reaches its floor tubing, radiator or baseboard heater.\n\n### Pressure rises / water leaks\n\n### The safety valve may be releasing water because pressure is too high.\n\n#### Useful things to tell us\n\nKeep clear of hot discharge and wet electrical equipment. If safely visible, record the gauge reading when cool and when heating—without changing settings.\n\n#### What we check and why\n\nWe compare pressure as the boiler warms, then check whether the expansion tank is accepting the growing water volume or the fill valve is admitting too much water. On systems that also heat tap water, a leaking internal coil can let higher-pressure tap water enter the heating loop.\n\n### Gurgles / bangs / whistles\n\n### The type of noise helps separate the causes.\n\n#### Useful things to tell us\n\nDescribe where and when it happens: when the burner lights, when the pump starts, during warm-up, or all the time. A bang at ignition or suspected fumes calls for prompt safety attention.\n\n#### What we check and why\n\nTrapped air, blocked water flow, pipe movement and mineral buildup can cause different noises. A bang when the burner lights requires a burner and fuel-safety check. Record when the noise occurs to guide the diagnosis.\n\n### Starts and stops constantly\n\n### Repeated short runs can wear parts and signal a mismatch.\n\n#### Useful things to tell us\n\nNote approximate run times and whether it happens during mild weather or when only one room or small area needs heat.\n\n#### What we check and why\n\nWe compare the heat that area needs with the least heat the boiler can produce. If the boiler makes heat faster than the water can carry it away, it may shut off quickly. We check water movement, temperature sensors and settings before deciding why it happens. This repeated starting and stopping is called short cycling.\n\n### Heat works / taps go cold\n\n### The boiler may heat both the rooms and the tap water through separate paths.\n\n#### Useful things to tell us\n\nTell us whether hot water is stored in a separate tank or made inside the boiler, and whether every tap is affected. A photo helps if you do not know the equipment type.\n\n#### What we check and why\n\nA combi boiler heats tap water inside the unit. An indirect water heater uses a separate tank warmed by boiler water inside a sealed coil. We check the tank or tap-water request, the temperature sensor and the water path used to transfer the heat.\n\nTHE MECHANICAL ROOM / OPEN IT UP 02 / EXPLORE IN 3D\n\n## More than a boiler. *See the whole system.*\n\nWarm floors, radiators, hot showers or a snow-free walkway. Choose a system, open the equipment and take a closer look at the parts.\n\nDRAG TO ROTATE · PINCH TO ZOOM HOT WATER OUT COOLER WATER BACK\n\nTAKE A CLOSER LOOK\n\nCONDENSING BOILER + FLOOR HEATING\n\n### The floor becomes the radiator.\n\nA boiler feeds the floor circuits. Each loop delivers heat, then returns the cooled water.\n\n**WHY PEOPLE CHOOSE IT**\n\nQuiet heat spread across the room.\n\n**WHAT TO KNOW**\n\nFloor response depends on the construction and controls.\n\nSELECT A NAMED PART\n\n#### The complete system\n\nTap a component to see its job and zoom closer.\n\nThese cutaways show the water paths in common home-heating systems. The floor loops are shortened so their connections stay visible. Select a part to explore how it moves water, transfers heat or controls pressure.\n\n### What changes from one system to another?\n\n**How the boiler handles cooler water:** a conventional cast-iron boiler can be damaged if returning water stays so cool that exhaust moisture turns to liquid inside it. A condensing boiler is designed to handle that liquid and recover its heat.\n\n**Where the heat goes:** floor tubing and radiators warm rooms. An indirect water heater warms tap water in a separate tank: boiler water passes through a sealed coil, transferring heat through the metal without mixing the two water supplies.\n\n**Which liquids stay separate:** the snowmelt example has water indoors and a water–glycol antifreeze mixture outdoors. A heat exchanger passes heat through metal plates between the two liquids while keeping them apart. Each side needs its own water movement and pressure control.\n\n[Indirect-water and snowmelt examples ↗](<https://www.caleffi.com/en-us/blog/6-heat-exchanger-applications>) · [Caleffi’s boiler piping concepts ↗](<https://www.caleffi.com/en-us/blog/5-example-systems-i36>) · [Manifold components & dimensions ↗](<https://www.caleffi.com/sites/default/files/media/external-file/01144_EN.pdf>) · [Wall-boiler reference & manuals ↗](<https://www.lochinvar.com/en_US/products/fire-tube-wall-mount-boiler-pg-heat-exchanger-knight/whb155n-100/100302089.html>)\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-what-changes-from-one-system-to-another>)\n\nUTAH WINTERS / DRIVEWAYS, STEPS & WALKWAYS\n\n## Snowmelt needs *a preseason check, too.*\n\nWarm liquid flows through tubing under the pavement to melt snow. The liquid, pumps, controls and drainage all have to be ready when the weather turns.\n\n### Keep the liquid protected\n\nGlycol is the antifreeze ingredient mixed with the water. Plain-water top-ups dilute it, and the chemicals that protect system metals need periodic checks too. Test the installed heating fluid before freezing weather arrives.\n\n### Confirm the heat can travel\n\nCheck that liquid moves through each tubing loop and that its pump works. Check pressure and the expansion tank that makes room for warming liquid. If a heat exchanger separates indoor and outdoor liquids, check both sides.\n\n### Check the response\n\nTest the snow sensor and controls that start the system. Cold pavement takes time to warm, and meltwater needs somewhere to drain without refreezing across a walkway.\n\n[Antifreeze & water-care guide ↗](<https://mtnmanplumbing.com/boiler-repair/water-quality-maintenance/?agentnet=md>)\n\nWATER, AIR AND PRESSURE CHECKS 03 / WATER, AIR & PRESSURE\n\n## The water is *part of the machine.*\n\nYour heating loop usually reuses the same water as it carries heat out to the rooms and back. Mineral deposits, called scale, can coat hot surfaces and slow heat transfer. Corrosion damages metal and sheds debris, while trapped air can interrupt flow. Repeated top-ups bring fresh oxygen and minerals into that loop.\n\n### Clean & compatible\n\nFill water is the water used to fill or top up the loop. Testing its mineral content and acidity helps select treatment that suits the boiler’s metal surfaces and water-quality limits.\n\n### Air under control\n\nRemoving trapped air when filling the pipes is called purging. An air separator keeps collecting small bubbles during use. Both need the right system pressure to work well.\n\n### Pressure that behaves\n\nA fill valve adds water. An expansion tank gives warming water room to grow. A safety relief valve releases excessive pressure. Repeated top-ups or discharge means something needs checking.\n\n- [GO DEEPER **Water quality & maintenance ↗** Mineral buildup, metal damage, antifreeze & care](<https://mtnmanplumbing.com/boiler-repair/water-quality-maintenance/?agentnet=md>)\n\n- [GO DEEPER **Air, pressure & moving water ↗** Why pipes get noisy, pressure changes & rooms stay cold](<https://mtnmanplumbing.com/boiler-repair/air-separation-pressure/?agentnet=md>)\n\n**See what happens when one number changes.** Explore how water carries heat, how antifreeze gets diluted and why valves need pressure.

The technician records when the problem began and what work was performed.\n2. ### Check the request and the path\n\n In this example, the technician confirms that the room’s thermostat requests heat and its water valve opens. The room’s pipes form one heating branch, also called a zone. Next, the technician checks water flow through that branch.\n3. ### Find the interruption\n\n The room’s branch contains trapped air. The technician directs water through that branch and out through its purge valve to carry the air out. With the air removed, water can circulate again.\n4. ### Check the result\n\n In this example, the room warms while its thermostat continues calling for heat. The technician checks for leaks and watches system pressure to find out how the air entered.\n\n**What the homeowner can contribute:** which rooms are affected, when it started, recent work and visible display messages. The technician adds measurements and equipment tests.\n\nThe teaching method follows a request through heat production, water movement and room delivery.

Ask who will diagnose your system and about their experience with your equipment.\n\nUtah’s S410 specialty license permits specified boiler installations and related piping. Connections to drinking water require backflow protection, a device that prevents heating water from flowing backward into the drinking supply; S410 installation of that device has a specific training condition. Gas work has separate certification rules and recognized exemptions. **Ask for the business license, the technician’s applicable credentials and experience with your boiler model.**\n\n### Check the credentials\n\nCheck the contractor’s active license and ask who will work on your boiler. These questions help you learn how they diagnose and service your equipment.\n\n[Check a Utah license ↗](<https://secure.utah.gov/llv/search/index.html>)\n\n### Ask for evidence\n\n- Do you service this exact make and model?\n- Will you explain the burner’s exhaust-gas test results and compare them with the manual?\n- Will you check water quality, water movement and the tank that handles expanding water?\n- Will I get the findings and post-repair results?\n\nReference: Utah R156-55a-301y (S410) and R156-55a-308b (natural-gas technician certification). [Read the current rule ↗](<https://adminrules.utah.gov/public/rule/R156-55a/Current%20Rules>)\n\nA SERVICE VISIT SHOULD LEAVE ANSWERS 04 / DIAGNOSIS & MAINTENANCE\n\n## What a thorough boiler service checks.\n\nA service visit follows the heat from the burner, through the water, and into the rooms. The model’s maintenance schedule supplies the cleaning methods and test limits for each part.\n\n### Burner, exhaust pipes & safety controls\n\nCombustion means burning fuel. An exhaust-gas analyzer measures how the burner is operating; looking at the flame cannot replace that test. Check the gas supply, air intake, exhaust, ignition and safeties, then use an analyzer as the manual specifies. At Utah elevations, verify the altitude configuration and fuel requirements for the exact boiler model. Burner work and gasket changes need the required leak and combustion checks before the boiler goes back into service.\n\n### Water quality and leaks\n\nFind where water is being lost before treating what replaces it. Test the fill supply and loop fluid against the equipment requirements. Inspect collected dirt and magnetic debris. Glycol is the antifreeze ingredient used in some heating systems. Identify the product and test its freeze protection and condition; color alone tells us very little.\n\n### Pressure changes, trapped air & moving water\n\nCold and hot pressure readings help reveal problems with filling and expansion. We also follow each thermostat’s request through its valve and pump, check for trapped air, and run zones together to see whether they affect one another.\n\n### The heat-transfer surfaces and their drain\n\nA condensing boiler recovers extra heat by cooling moisture in the exhaust into liquid water, called condensate. That liquid needs a clear drain and a water-filled trap that blocks exhaust gas. A neutralizer uses material that reduces the liquid’s acidity; that material needs replacement when used up. The heat exchanger—the metal surface that passes burner heat into water—also needs the model’s specified cleaning method.\n\n### Controls and operation after repairs\n\nCheck the temperature readings and control settings while the boiler runs. Outdoor reset adjusts the heating-water temperature with the weather, lowering it on milder days while keeping the rooms warm. After repairs, run the affected zones and hot-water call, record the results and explain any remaining fault.\n\n[What to keep in your boiler service record ↗](<https://mtnmanplumbing.com/boiler-repair/water-quality-maintenance/#br-service-record>)\n\n## Repair or replace? *Ask what the next dollar fixes.*\n\n### Repair a defined fault\n\nA serviceable boiler, available parts and a clear cause can make a targeted repair sensible. Correct the condition that damaged the part.\n\n### Fix the system around it\n\nAir problems, constant water replacement, poor piping, poorly arranged thermostat-controlled areas or wrong settings can follow a brand-new boiler. A replacement quote should address those findings.\n\n### Consider replacement\n\nUnsafe or unserviceable equipment, unavailable critical parts, serious heat-exchanger damage or repeated costly failures warrant a replacement comparison. For affected Triangle Tube units, recall status and manufacturer closure belong in that decision.\n\n**Size the boiler for the house.** A replacement needs a calculation of how much heat escapes the building in cold weather. The boiler must replace that heat. Its lowest heating output matters too: it should suit small heating requests without constantly restarting. Tap-water demand, exhaust piping and required water temperatures also affect the choice.\n\n## The questions worth asking.\n\n### Does a boiler boil the heating water?\n\nThese systems heat liquid water and circulate it through floor tubing, radiators or baseboard heaters. The water gives up heat in the rooms, then returns to the boiler to be warmed again.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-does-a-boiler-boil-the-heating-water>)\n\n### What pressure should my boiler run at?\n\nCold pressure needs to keep the highest pipes filled. As the water heats, the expansion tank takes in the extra volume and limits the pressure rise. Recurring pressure loss, a large cold-to-hot swing or a dripping relief valve gives the technician a specific problem to investigate.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-what-pressure-should-my-boiler-run-at>)\n\n### Should I drain the boiler water every year?\n\nA healthy closed loop can keep using the same water. Service includes checking its condition and any treatment chemicals. Cleaning or replacing the fluid is useful when test results, debris or a repair call for it, using the equipment’s service instructions.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-should-i-drain-the-boiler-water-every-year>)\n\n### Does a water softener protect my boiler?\n\nCheck the boiler’s water-quality limits first. A household softener exchanges hardness minerals for sodium, leaving dissolved salts in the water. Some boilers specify a minimum hardness as well as other water limits, so the fill supply needs testing before treatment is chosen.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-does-a-water-softener-protect-my-boiler>)\n\n### Can I just bleed the noisy radiator again?\n\nRecurring air deserves diagnosis. Low pressure, leaks, frequent filling or other oxygen-entry paths may be involved. Bleeding hot equipment also risks burns and pressure loss. Have the cause checked rather than repeatedly replacing water.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-can-i-just-bleed-the-noisy-radiator-again>)\n\n### Is antifreeze a good idea in every boiler?\n\nNo. Glycol, an antifreeze ingredient, is useful where freezing is a concern, but the boiler must allow the product and concentration. It changes fluid properties and needs periodic testing. Do not add automotive antifreeze or mix unknown products.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-is-antifreeze-a-good-idea-in-every-boiler>)\n\n### How often should a boiler be serviced?\n\nMany gas-boiler manuals call for annual professional service. The visit checks combustion, cleaning, water condition, circulation and safety controls. Glycol deterioration, recurring debris or an active fault may call for an earlier visit.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-how-often-should-a-boiler-be-serviced>)\n\n### Can the boiler heat my showers too?\n\nA combi boiler heats tap water inside the boiler. An indirect water heater stores tap water in a separate tank warmed by a sealed coil of boiler water. Metal surfaces pass the heat across while keeping the two water supplies apart.\n\n[Link to this answer](<https://mtnmanplumbing.com/boiler-repair/#answer-can-the-boiler-heat-my-showers-too>)\n\nCHECK YOUR UNDERSTANDING\n\n## Can you explain it?\n\nThe boiler is running, but one room stays cold. Where would you check next?\n\nTry answering in your own words, then compare your reasoning.\n\n### Show the answer & why\n\nFollow the branch serving that room. Check whether its thermostat is requesting heat and its valve opens, then whether water flows through its radiator or floor tubing. A closed valve or trapped air can interrupt that path while the rest of the house heats normally.\n\n- [Lesson 2 · Water & antifreeze →](<https://mtnmanplumbing.com/boiler-repair/water-quality-maintenance/#br-lesson-start>)\n\nRECENT BOILER & HEATING WORK\n\n## In the boiler room. *Out in the field.*\n\nSee recent boiler and related plumbing work from our team.\n\nSANDY & NEARBY COMMUNITIES\n\n## Local boiler help.\n\nOur office is in Sandy.

Super helpful and informative. Communicated well and was punctual! Posted on Google Nathan Trustindex verifies that the original source of the review is Google. Tyler from Mountain Man Plumbing replaced my in-house main water shutoff valve and the pressure reducing valve (PRV) with a very practical new system that enables me to view the line pressure coming in and any drops in pressure easily. Very good looking workmanship.\n\nPrior to the work Tyler came out to my home and provided an estimate on the work, and stuck to the estimate. He's been easy to work with, cleaned up after himself, and also allowed me to change an appointment close to my originally planned estimate appointment over the phone. The website is also easy to use and efficient for scheduling an estimate. Thank you! Posted on Google Jeremy Trustindex verifies that the original source of the review is Google. ⭐⭐⭐⭐⭐\n\nI had a great experience with Mountain Man Plumbing. Tyler showed up right on time, was professional, and got everything taken care of faster than expected—finishing the entire job in less than a day. He replaced our water heater, took care of the valves, and installed a new expansion tank, all with great attention to detail.\n\nEverything is working perfectly now, and the whole process was smooth and stress-free. Highly recommend Tyler and the team if you’re looking for reliable, efficient plumbing work! Posted on Google Dana Trustindex verifies that the original source of the review is Google. Tyler was very professional, polite and honest. Instead of trying to sell me new parts or a whole new water heater he showed me that some of the heating elements just needed cleaned. I would recommend this company for anyone looking for honest help to get the right fix without getting ripped off. Posted on Google Kyle Trustindex verifies that the original source of the review is Google. Honest, thorough (caught a problem a couple people had missed), on time/reliable Posted on Google Barb Trustindex verifies that the original source of the review is Google. Efficient, clean, and knowledgeable. Posted on Google Wendy Trustindex verifies that the original source of the review is Google. Tyler was great! Hard to find a plumber who preps for a service call like he did. He asked questions before he came over to fix a shower valve so he could make sure he had the right parts for the fixture so he was as efficient as possible when he got here. Communication was great prior to the service call and during. Fixed everything I needed in a couple of hours for a very reasonable price. Posted on Google Ellen Trustindex verifies that the original source of the review is Google. Great service, fair pricing, quality work. I feel lucky to have found Tyler Nerdin at Mountain Man Plumbing! Posted on Google Karthik Trustindex verifies that the original source of the review is Google. Tyler was great. He kept his schedule and his work was flawless. Definitely knows his craft. Posted on Google Jon Trustindex verifies that the original source of the review is Google. Great service. Tyler updated everything that had been missed with my old water heater, even unplugged my floor drain. Highly recommended. \n```\n\n [Read More Reviews →](<https://mtnmanplumbing.com/reviews/?agentnet=md>)\n\nOUR SANDY OFFICE\n\n## Right here. *Close to home.*\n\nMountain Man Plumbing\n\n688 East Union Square, Suite 204\nSandy, UT 84070[Open our Google profile ↗](<https://g.page/r/CaOTt7DCa0I_EBM>)\n\n[Mountain Man Plumbing office in Sandy, Utah](<https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d3030.3167966444817!2d-111.8726262!3d40.5787622!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x432a303481edfacf%3A0x3f426bc2b0b793a3!2sMountain%20Man%20Plumbing!5e0!3m2!1sen!2sus!4v1788898396959!5m2!1sen!2sus>)\n\nWARM ROOMS.
