Installing heated floors under hardwood floors

We are considering having heating units put under our hardwood floors in certain areas. Does anyone have any idea of who does this type of work and the estimated cost?
I don't think this is something my fiance can do but he swears it is easy.

Any help you give is appreciated.

Radiant is often retro-fitted but you need access to the underside of the floor

Not sure what you mean by 'heating units'

Assuming that you are talking about radiant heat, it is an easy DIY project and the instructions which come with the package are very easy to follow. The cost varies depending on the system you choose, approx. $6.00 to $8.00 per sq.ft plus the cost of a new thermostat approx. $80.00 to $130 for a programmable one. Just Google radiant floor heating and you will see the choices available.

I have only installed such a system with a new ceramics floor. I donít know how it will work with new hardwood floors where you need to nail each piece to the floor or with laminated flooring

One think to consider is what is under the existing floor. If itís an unheated area you will loose a lot of heat from the radiant heated floor.

Another is the source of power. If you already have baseboard electric heating in you rooms then it is much easier because you can terminate the heating cable just under the existing wall thermostat and no more breaking the walls. If you are not comfortable working with electricity, you should get an electrician for the final connection to the thermostat.
