Hydronic heating is a type of home heating system that uses water as the medium for transferring heat energy. It is an efficient and cost-effective way to provide warmth in your home, especially during cold winter months. Understanding each component can help you choose the best system for your home and get the most out of it. JNR Plumbing explains the basic components of your hydronic heating system below:

The Boiler

The boiler is the heart of your hydronic heating system. It produces hot water and steam which is used to transfer heat energy throughout your house. Boilers come in various sizes and capacities depending on how much heat needs to be generated for your particular living space.


For your hydronic heating in Stamford, CT, the pumps are responsible for circulating the hot water and steam throughout the system. The pumps are typically connected to the boiler via pipes and can be set up in various configurations depending on the layout of your home’s plumbing system.

Expansion Tanks

An expansion tank is an important part of any hydronic heating system because it helps maintain proper pressure levels in the system. When water is heated, it expands and if there’s nowhere for this expansion to go then the pressure can build up and cause damage to your system. If the expansion tank is damaged in any way, be sure to call for hydronic heating repair right away.

Radiators or Convectors

The final components of your hydronic radiant floor heating are radiators or convectors which distribute the heat throughout your home. Radiators and convectors are the devices that transfer the heat energy from the hot water to your home. Radiators are usually connected directly to the boiler while convectors can be connected further away from the boiler via pipes.

Radiators typically use heated air to warm a room, while convectors use hydraulic fluid (usually glycol) that is circulated through coils to release heat into space. Both the radiator or the convertor work similarly by absorbing heat energy from the hot water circulating through them, and then radiating the heat back out into your living space.
