Underfloor heating reliability/costs

[Turnipinatutu]

Thinking about the house we're trying to buy and renovate etc.
Radiators, although useful, alway seem to get in the way of room layouts!

Could any of you experienced people give me some info and views on underfloor heating please?
We would be hoping to extend the kitchen and fit a wood burner, so do we need any other form of heating?
I think we'd like an engineered oak floor. Could this work with UFH?
What's the best type? Does it go wrong and then you need to lift the floor?
Expensive to run?

TIA

You won't ever have to lift the floors as you would never put any joints under the floor. And as plastic pipework is used for UFH you won't get any problems with pinholes or corrosion as you can with metal pipes. Plastic pipes don't fail. (As long as it's not installed too close to the wood burner and melts!)

Running costs should go down as a radiant heating system is far more efficient than a convection one.

Engineered should not be a problem however check with flooring manufacturer as they will be able to advise you.

I was only thinking of fitting it in the one room, a large kitchen/dinner.
Is electric better or cheaper than pipes?
