Underfloor heating from radiator circuit.

Underfloor heating can also be a hydronic heating system. These systems are fully pumped meaning that the circulation of water in the central heating circuit is pumped. For all rooms greater than 15m2 you need separate primary flow and return pipes from the boiler or you can tee off the main central heating pipes before the first radiator. Underfloor heating is easily installed as part of the build schedule and it is also cost effective offering far more benefits than a radiator system at comparable running costs.

Teeing off your radiator pipes this means that when your existing radiators are programmed to come on usually be your time clock next to the boiler the underfloor heating pump will also come on providing that both your radiator thermostat and your underfloor heating thermostat are calling for heat please note the underfloor heating pump will not run until the water temperature in the pipes has. This page however refers to hydronic heating with radiators as the principle heat emitters. I am temporarily going to connect my ufh manifold to my current radiator circuit by tee ing off my main flow and return. If the ufh system is connected to the radiators it can t be controlled individually.

It can be expensive to heat a whole house using electric underfloor heating so having radiators in the larger rooms is the way to go if you opt for dry ufh. We are installing wet underfloor heating in the new rear extension and part of the basement. The underfloor heating system uses its own feed from the boiler with a blending valve and pump fitted at the manifold to lower the water temperature entering the underfloor heating system. If you really want ufh throughout you should give serious consideration to having a wet system installed.

The easiest way is to connect a flow and return from your existing radiator circuit i e. Our promise to you we ll price match on like for like products. Meanwhile the hot water from the boiler goes directly to the radiator system and hot water cylinder. As you can probably imagine using electric underfloor heating throughout the house is not all that energy efficient.
