Retrofit wet underfloor heating in conservatory

[Lucasdemoley]

Hi All,

I am considering my option/ the cost of installing retrofitting an underfloor heating system in my conservatory.

The conservatory is about 5 years old and has a tiled floor with a single radiator. Its quite small at around 8m2 floor area.

My current thinking is that, could I plumb off the radiator to provide the underfloor heating? By doing this I could avoid the need for a separate pump, but would I need a manifold/ gubbins or can the pipes just extend into the screed?

The next question I have is what is the minimum thickness required for underfloor heating? I currently have about 25mm to play with above my current tiles. I can remove my existing tiles and potentially the screed below, but not sure if this would be enough.

Don't get me wrong, I'm not looking for a perfect year round system, just something that will provide a little more heat into the room, and the thought of a warm floor is quite appealing! We are happy to use an electric fan to top up the heat when it is cold.

Please don't suggest electric heating mats, this is something I am not interested at all in using, and if the above cannot be achieved then I will leave it.

Many thanks for input/ advice.

The proposals you've described are totally inadequate for underfloor heating.

Look at an air to air heatpump.....

An FJVR return temperature limiter will do what you want.

The valve body is about £22 quid and the sensor is about the same.
BES supply them.
10 sq/m is about their limit.

Wall mounted versions are also available.

A double meander pipe configuration should be used as per danfoss recommendations.
