Essential Maintenance for Your Radiant Heating System

Essential Maintenance for Your Radiant Heating System

While hydronic radiant heating systems are famous for their reliability and low maintenance requirements, they aren't entirely set-and-forget. Regular maintenance ensures your system runs efficiently for decades.

Annual Boiler/Heat Pump Inspection

The heart of your system needs an annual check-up. A technician will inspect the heat source for proper operation, clean necessary components, and ensure there are no safety issues.

Checking System Pressure

Hydronic systems operate within a specific pressure range. If the pressure drops too low, the system may struggle to circulate water effectively. Your technician will check the expansion tank and pressure reducing valve.

Fluid Quality

The water inside the system can degrade over time, leading to corrosion or sludge buildup. Glycol (antifreeze) mixtures, if used, also break down and lose their effectiveness. Testing the fluid pH and inhibitor levels is a critical maintenance step.

By scheduling an annual check-up with Prime Heat, you can catch minor issues before they become major repairs, ensuring your home stays warm all winter long.
