Hello all, So I'm working on my own house and the plan is to install water based underfloor heating for the downstairs. Currently I have a suspended timber floor which appears to be in good condition (if not 100% level), I was wondering cost-wise if I'm prepared to do most of the work myself how much would I be looking at to convert it to an insulated concrete floor. I already have the insulated I would need. I also would appreciate any advice, horror stories, or opinions. Cheers.
