Underfloor Heating From Radiator Circuit

You could even save money on your energy bills as ufh is up to 25 more efficient than radiators.

Underfloor heating from radiator circuit. 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. Our promise to you we ll price match on like for like products. We are installing wet underfloor heating in the new rear extension and part of the basement. The easiest way is to connect a flow and return from your existing radiator circuit i e.

Underfloor heating can also be a hydronic heating system. 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. If the ufh system is connected to the radiators it can t be controlled individually. As you can probably imagine using electric underfloor heating throughout the house is not all that energy efficient.

Meanwhile the hot water from the boiler goes directly to the radiator system and hot water cylinder. Now i know when installing correctly to combi boiler this will need 2 zone valves and wiring centre etc. 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. 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. 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. 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. You ll ideally go the s plan route and use two port valves to ensure boiler interlock and control one for the rad circuit and one for the ufh circuit but this is no different to using s plan to control one radiator heating circuit and domestic hot water dhw some planning will need to take place on how you time control the system so if you are using simple rotary dial thermostats for the rads and underfloor then a two channel timer will be needed or a three channel to also control dhw.
