Bathroom heating lights

Arran Cameron

What do electricians think of bathroom heating lights?

They are the highest power devices normally connected to a lighting circuit. Many years ago I had one with a 750W heating element. Combine this with a 100W incandescent bulb and you have a device which consumes 3.7A. Two of these devices will overload a 6A lighting circuit.

Should heating lights be designed in a way to easily connect the heating element to a different circuit than that used for the light? Alternatively, should they be powered from a ring main rather than a lighting circuit?

    I installed several of those heat and light units recently in a holiday cottage without any “proper” heating. One in each bedroom and one in the kitchen. I put all four on a dedicated 16 amp circuit. 

    Cheap, simple and tenant resistant. Not ideal for full winter, but handy for extending the letting season a bit. 

    Also used on farms for warming piglets in severe weather. The dim orange glow in heat only mode is said to permit of a sow seeing her piglets and not rolling on them, as is a risk in full darkness.
