Caring for Your Hydronic Heating System

During the winter season, a hydronic heating system is beneficial as it heats the water in your bathroom while keeping the floor (and other amenities) warm and comfortable. The system is energy-efficient, safe, and good for the health of those who live with it.

To continue enjoying your hydronic heating system for years to come, professional, regular maintenance is necessary. This helps save money in the long term, since technicians can spot the first signs of a problem, before it becomes a costly repair.

Here are some maintenance steps you can expect from professionals:


Caring for Your Hydronic Heating System


1. Inspect for standing water.

Your technician may turn up the thermostat, allowing temperature and pressure to build in the system for a few minutes before checking pipes and valves in the boiler room area for leaks.

2. Check water temperature and pressure.

The technician may check the temperature and pressure gauge (which should be within the range of 82⁰C – 93⁰C). Proper pressure will be between 12 – 25 PSI for a two-story house. Should either of these measurements fall outside the range, your system may need repair.

3. Lubricate circulating pump.

The pump regulates the flow of water into the circuit and may require lubrication to prevent friction within the piping system.

4. Clean soot.

Inside the combustion chamber in the boiler, soot can accumulate. Your technician’s regular maintenance includes removal of dust and other materials. This effort keeps this debris from interfering with the system by circulating into the water.

5. Dust radiator surfaces and straighten fins on baseboard heaters.

Fins that are badly bent may require a fin comb and straightening to prevent more dust collection.

6. Get air purged from the radiators.

Technicians may open the bleeder valve on each baseboard run or radiator, until water begins to trickle. Valves are then closed after the excess air has escaped.

7. Drain and flush the system.

Several experts suggest residential hydronic heating systems be drained and flushed once every five years.


Caring for Your Hydronic Heating System


Hydronic heating systems vary by structure, model, and individual components. Because they’re not all the same, they require regular maintenance performed by a professional. Since the system gets the most use during the winter, checking your system in the late summer or fall can save you from malfunctions during colder months.
