heating in a new en-suite WC

[Mikejf]

Hi,

Does anyone know if some form of space heating is required by building regs in an en-suite WC. It will be a room built in a bedroom containing just a WC and sink and it will be 1m x 1.2m.

Some online calcs say you need around 150watts or 400 BTUs for a room that size, but is one required at all as you will be in there for only a few mins (depending what you ate the night before!!)

Thanks

Mike

No requirement for heating in an ensuite.

Don't think the Building Regs mandate any heating anywhere, do they?

Does it have any external boundaries (wall, ceiling, floor) ?

If enclosed by other heated rooms then it'll stay warm by conduction through the walls. If it has any external walls, or a poorly insulated ceiling or floor, then it'll settle at some temperature between the rest of the building and the outside. It could well be a bit uncomfortable in cold weather.

If it has an extractor fan it will draw warm air in from the bedroom, which will help warm it (after it's been used).
