There are many types of heating systems that you can have for your home, and all of them can potentially fail and need repair. If you have a heating system that uses hot water that flows through radiators, you may run into an issue where the radiators have nothing but cold water flowing through it. Here is how you can identify the system.
Understand How the Radiator Works
It helps if you understand how a forced hot water radiator system works. The system works by heating water in a central boiler, which then moves into an expansion tank. A circulator pump then moves the water from the expansion tank and into the pipes going to the radiators. Those radiator pipes have a section that is exposed pipes in each room of the home, where the heat gets released. As the water cools off, it flows out of the radiator and into return lines that go back into the basement where the process starts all over again.
Check the Water Expansion Tank
That water expansion tank operates by having a pocket of air at the bottom of the tank, and the hot water near the top. It then pushes the hot water out of the tank with the pressure caused by the pocket of air. It is possible that there is a problem with the water expansion tank. There should be a pressure gauge on the tank that tells you how much pressure is being put on the hot water. Be concerned if there is no pressure in the tank as displayed on the pressure gauge. This means that there is an issue with the water expansion tank that will need to be repaired by a professional.
Check the Circulator Pump
With the pressure checked, take a moment to identify if some of the radiators are not working or if all of them are cold. If all of them are cold, you likely have a problem with the circulator pump. You may even be able to feel the heat from the pipe before and after the water reaches the circulator pump. If the pipe before the water reaches the pump is hot, but the pipe on the other side is cold, then you know there is a problem with the circulator pump.

Working with HVAC contractors is an important part of being a homeowner. Not only do your contractors ensure that a new system you buy is properly installed, but they also ensure optimal performance throughout the years through a series of regular inspections, maintenance services, and repairs. But there are lots of things you can do in between your contractor's visits to ensure that your HVAC investment is always in tip top condition, aside from cleaning out the air filters. After working with my dad for more than a decade in the HVAC business, I've put together a few methods homeowners can use to maintain a well working system, and I have published those tips and tricks right here on this blog. I hope some of the information you find here helps you on your journey as a homeowner!
