Upgrading Heat Lamp Bulbs in Bathroom Installation

[rus]

Is it possible to install red heat lamps in bathroom 3-in-one fan assembly in place of white inefficient heat lamp Supplied to increase bathroom temperature ?

Welcome to PF.

The limiting factor will be the heat dissipation in the existing fixture. Is it a recessed fixture for the bulb part? Is there a label inside the fixture that specifies the maximum bulb wattage? Can you post a picture of the fixture (use "Attach files" below) or give us a link to the datasheet?

. . . . or even total load, additional to what lights use. In UK, at least, the lighting circuit will be very lightly fused and any serious source of heat will demand higher current than 'lights'. IMO, the solution to warming your bathroom is to use an IR heater or fan heater, mounted on the wall. that would be fed from a handy ring main. 1kW can make a pleasant improvement to your bathing experience. A bit of a pain unless you are happy with (and capable of) that sort of installation.

I really hate the inadequate thermal design of your average lighting unit. But, these days, LEDs elininate the 'cooking smell' that you can get. Another point could be that a glass shade around a replacement IR bulb could absorb a lot of the radiated IR and get hotter than the same power rated light bulb. You'd need to be sure that a fitment would be appropriate for an IR source.
