I may at one point want to install underfloor heating retrospectively. I was wondering whether anyone could answer the following questions:
1. There are natural stone tiles in the kitchen/hall. I want to install underfloor heating that is connected to the central heating (i.e. using hot water), not electrical. I know that I would have to remove the stone floor and dig out the concrete floor. How deep would I have to dig? (I seem to remember reading somewhere 20-25 centimetres. Is that right?) Also, how much would that cost for approx. 15 square metres? (I live in London SE17.)
2. I may want to convert the garage into an additional room & install underfloor heating there as well. The garage is about 17 centimetres lower than the hall/kitchen. Would that be enough, or would I still need to dig deeper? (Again - I don't want electrical underfloor heating.)
3. How much is it to install underfloor heating (labour + materials) per square metre?
(It's a total of around 32 square metres: 15 for kitchen/hall plus approx 17 for the garage.)
I don't want to have this done anytime soon - I just want to know how much it would cost.
Cheers!
