[abedoo]

dear experts.

i need to heat a room of 100 m2 up to 30 degrees. can i use the ellectrical under floor heating , or its better to use the water underfloor heating?

how efficent could this be , can the under floor heating reach such temp ?

thanks for advice

My experience, indirect from people with both systems, is that wet systems heated by gas are much cheaper to run and have a longer life.

Elements fail but pipes without buried joins seldom develop leaks.

Electric elements heat to full element temperature ( higher than the required floor temperature ) and there is a delay before the floor thermostat sees the floor is at the required temperature and switches of the heater. The excess temperature in the element continues to heat the floor.

Wet systems control the temperature of the water flowing and give a better control.

Heating a room by underfloor heating is not suitable for a room that is ventilated as the floor temperature required to heat the changing air means the floor can be un-comfortable to stand on.

You should consider additional means of heating for the area.

Is this a question for UK installation as the temperature requirements/regulation of floor heating could be different.
If have a product in mind the manufacturers instruction would dictate the output heat. BS7671 (electrics England and Wales) states if the floor is to come in contact with skin/footwear, that the surface floor area temperature should be limited. An example given is 35 degree c.
In general terms, the wet systems are more efficient than electric, but that could also depend on the costs of your service units per kWh.
Would this be a primary heating source to the room?

Is this a windup, surely in the OP's location the ambient is about 40 C

Not much choice in Saudi apart from a few hotel bars.
