Ok the missus wants the whole of the downstairs tiled. That's kitchen, hallway and dining room. Plus each bathroom.
We want to get undertile heating in. Does anyone have experience with these?
What are the quality like?

The house is pretty well insulated.
I've seen in wickes you can get 150 to 1000watt ones.
What am I looking at running costs and how hard Is it to install?
 
I fitted underfloor heating to our kitchen,around 10m2,then tiled over.Dead easy to do,I got a loose wire kit as the kitchen is an odd shape.Can't comment on the running costs as I have solar panels which help ;) but I seem to recall the sales guy I spoke to before buying the kit said approx 35p a day,for my 10m2,rated at 150W,depending on how many hours a day you have it on etc.
Bought the kit from these guys,really helpful and about the cheapest I could find,I'm looking to buy another kit for our conservatory:
Underfloor Heating | Electric Floor Heating | Heating Systems
 
Just remembered the 35p a day was for heating the dining room up as well as the kitchen but didn't go for that in the end.
 
What kind of heat dp you get from the 150w? Or is it no different to central heating?
 
I have underfloor heating in both my kitchen and bathroom..
To be honest I rarely use it,it's takes so long to heat up its not worth the hassle for me..
The bathroom runs off the same feeds for radiators so I could just leave it open but I don't see the point of keeping bathroom warm as it's just me so I open a few hours before a bath etc..and kitchen has separate electric supply that I never use as kitchen also has rads.
 
What kind of heat do you get from the 150w? Or is it no different to central heating?

I've used it for both primary heating and as a 'floor warmer'(we have a rad in the kitchen as well)Think the maximum I've had it up was 26degrees.The thermostat can read floor temp,air temp and/or both so you can set it to read which ever
 
I will be fitting my kit in around a weeks time,want me to take photos as I fit it?
 
Follow a few simple rules and it's easy enough to do. You'll need a multimeter.

Decide whether it's primary or secondary heating. Primary if it's the only source. Assess the floor for stability, if it flexes over-board with 12mm ply. The mats are 0.5m wide so play around with sketches/CAD to decide mat size(s). You can run more than one mat from a single controller. You can cut the mats to bend them around stuff provided you don't cut the heating wire.

At every stage check the resistance hasn't changed using the multimeter. Seal the sub-floor before laying mats. I cover mats with self-levelling out of preference but you could just rely on the tile adhesive. If you float the self-levelling use a plastic float.
