underfloor heating in kitchen. - Tile Advice

[jwatson]

Thinking of installing some underfloor heating in my kitchen at the end of summer, and i was hoping for some advice on what sort of tile to use for best heat distribution and energy efficiency. thanks as always in advance.

What is on the floor now, Concrete/Screed or wood ?
Is this to be sole source heating or do you have radiators etc ?
What floor covering will you be using and any height issues ?

Ditto the above plus what sort of underfloor heating is it and what output.

 

[jwatson]

The sub-floor is concrete throughout the whole ground floor. and is tiled with ceramic 300's. It is to be the primary heat source in the kitchen, so may go for a higher wattage??. we currently have a radiator but it is in the way really, we plan to take it out and replace that part of the kitchen with more units.

sorry electrical underfloor heating poss 200w?? not really sure.
last winter was quite cold in this house. asume the concrete conducts the cold right through.

I'd go for the 200W and also a thick layer of insulation.

If it was cold, I'd also consider keeping the rad until you've done a winter to see if you can cope with removing it just to be sure. Especially as it's your own kitchen and not a customers you'd need to go back to etc.

10mm min insulation after old tiles removed, 200w cable system .
My clients have given feedback over the last year about how efficient the UFH is and 99% say its all they need.

any tile advice???

It is all down to personal preference, were you thinking stone or tile.
If Tile then deffo Porcelain for me.

 

[jwatson]

cheers. i suppose it is just pp.

so will Proberly end up doing porcelain or maybe if the budget stretches enough a sparkly quartz "something shiney" is how the mrs describes what she wants." we will see

 

[Gazzer]

Just be careful with the "Sparkly" as some are not compatible with UFH.

Natural stone or ceramic will be better with ufh than sparkly resin tiles.

Underfloor heating at 200w/m2 is from our Conservatory range, but good to also use in Kitchens as you will lose some floor space to the Kitchen units.
Will be full heating (primary heat), depending upon the heating coverage of the total gross area, how well the dwelling is insulated and the heat loss figure for your gross area.
As over, 10mm insulation in the floor also.
The Heat loss figure for your area is about how each surface loses the heat: Floor surface, internal walls, external walls, doors and ceiling.
Very long winded calculation, but in general 200w/m2 is good for any Conservatory, so will be good for a Kitchen.
Warm regards, Keith.
