Advice please

[mikel]

I have a customer who is a bathroom designer/fitting company. They have asked me to look at a job where the house occupier wants to install 'in floor lighting ' and under floor heating in a bathroom.

I've done under floor heating before but not in floor lights. I might be being blinkered but I can't see a way that the 2 are compatible. Anyone got any experience of this sort of work or advice on how it can be done

It would surely be a case of leaving sufficient space around any lights with your floor heating system. I assume lights would be toward the edge of the room not the middle. You would miss other obstacles such as hand basins, toilets, shower trays, and any pipes coming though the floor.

You could ask them for a specification on what they want. This ususally means you can charge if you have to do it, as they are the designers it should be their job. If you choose and supply it get them to ok it before buying it. Not much help on the kit side I know but I have had problems with similar situations before so be a bit careful.

I intend to be very careful with this one. One concern I have is the transfer of heat from the under floor heating through the lamp fitting. I can imagine the fittings could get rather warm at times

It would be possible to install LED lighting in the floor similar to the deck type of lamp fittings. Heat would not be that much of a problem (no burned toes), the heat will be dissapated by the area under the floor, like others have said leave plenty of room around the fittings. Another option is to go with end emmiting fibre optics with steel end fittings, expensive but no wiring problems as the driver is outside the bathroom. It would depend on the budget.

I did that on a job ,just left a clear area for the lights, mind you there were only two , LED things , with the driver unit on the garage ceiling below. I have a picture I'll se if I can make it appear , don't hold your breath!!. The floor heating finished at the end of the bath.

Just wired up a floor heating system this week. The tilers prefered heating system is this stuff:

By using wire rather than mat, you can leave spaces wherever you need for lights, toilet, basin etc etc

Floor heating mat on same job ,sorry it dosn't show the floor lights.

Just a quick thought.

Surely as long as the ambient temp at the fitting was not going to get above that allowed by the manuf' then they would be compatible?

Floor heating don't get that hot, and you have quite a heat sink around it, especially if you have a concrete floor & tiles?

You may need to do some heal loss calculations from the "u" values and heat inputs from the lights & floor heating.

However, as has already been suggested there are designers involved, get them to do their job, or are they just "aesthetic" designers?...
