Hydronic heating works by piping heated water or other liquid around the house to heating panels, heat convectors or under-floor tubesi,ii.

Hydronic heating has many benefits: it doesn't need fuel such as wood or gas to be burned inside the room to be heated. It's quiet and heats the entire room . It doesn't circulate allergens or dry out the air. There are no electrical connections or exposed flames, so it's relatively safe in homes with young childrenii.

Quiet, clean, warm and comfortable - it's hydronic heating.

How is the liquid heated?

The ways to heat the liquid will depend on factors such as climate, fuel availability, budget and house design:

A boiler (gas, electric, woodiv or oilv,vi) is a common way to heat piped watervii.

A wood fire stove or wood heater can be used to heat water in a hydronic systemviii,ix,x.

Solar panels or evacuated tubes, usually roof mounted, can be used as part of a hydronic heating systemxi,xii,xiii.

Geothermal pumps use heat from the soil and air-sourced heaters to extract heat from the airxiv.

A hydronic heating system needs a heat emitter, such as floor coils or a room heater, to warm each room. The liquid is pumped through the system while heated. Hydronic home heating can include individual thermostats that warm certain zones or rooms to specific temperaturesii.

Hydronic heating uses heated water or liquid piped around the home.

Heat emitters include:

Under-floor systems, which use tubes - often in a concrete slab - to provide heat from the flooriii.

Hydronic panel or tubular radiators, which can be installed on the wall or sit on the floor in each room to provide radiant and convective warmthii,xv. Custom-designed radiators can be installed under windowsills, along glass panels, in ceilings and in walls for heating rooms with customised layouts or stylesxvi,xvii. Low-surface temperature radiators provide safe heating by being cool to the touch on the front panel, with pipework and valves concealedxviii.

Trench convectors, which are usually recessed in the floorxvi,xix.

Towel rail heaters, which can be in installed in bathrooms or laundries for drying towelsxx,xxi.

These heaters provide radiant heat and heat through natural convection. Fans can be included in the emitters to help distribute warm airxxii.
