Boiler Repair questions, answered by experts

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

If you’re unsure who to call to fix your boiler, you have a few options. One is to call a dedicated boiler service. However, you can also call a plumber or HVAC technician for boiler repair services. These pros will have the tools, knowledge, and experience to fix common boiler problems.
