It will be necessary to have 2 separate feed and return pipes from the boiler one for the underfloor heating and one for the radiators or you can tee off the primary feed and return pipes before the first radiator.
It can even run off of the existing radiator circuit great for new kitchens or living spaces.
How a wet system works.
You can keep independent control of each with the help of a zone valve which will keep energy usage down and in turn lower your running costs.
If the ufh system is connected to the radiators it can t be controlled individually.
With each circuit controlled on off by a valve in turn controlled by a wiring.
In houses not occupied during the day underfloor heating s slow warm up and cooling time which can be up to four to six hours may not.
Only if the area isn t greater than 15m2 and the return water temperature limit valve is being used.
Can i connect the ufh to the radiators circuit.
In this scenario ufh can be installed without the need to replace or disrupt the existing radiator system.
But i want to replace some of them with a wet underfloor heating system.
Combining radiators and wet underfloor heating systems.
The pump can be controlled 2 ways option 1.
