Complicated multi solution for a skinflint

[satinseat]

hello all,
I need a heating solution for a small unheated toilet.
Ideally a wall fan heater that is multi controlled so not on unless occupied and temperature is cold enough.
was thinking a thermostatically controlled wall fan heater (so regulated to operate below a reasonable temp only) AND a pir ceiling switch to make it work when occupied.
Sure its complicated but is there anything like it on the market or could it be done please?

I'd go for a wall panel heater with built in stat and/or timer. PIR operated would be next to useless as most heaters would take time to actually heat the space after turning on.
how long are they planning on spending in there, hang on, don't answer that.

You may need a constant low level temperature to protect water pipes from freezing if it’s that cold.
PIR to bring on a fan heater when someone is occupying

Thanks for that, not long at present as it's colddddd but didn't want permanent heat source, to avoid costs, just when occupied, hence the fan which would be instantish.

That's why I suggested a timer built in to the heater, to avoid a permanent heat source for economic reasons.
In my experience downflow fan heaters even for small rooms need to be at least 2kW to have any effect, but even that won't be as instant as you think. You'll have vacated the room by the time it gets cosy, and you'll still have a cold seat initially.

If you got a smaller timed heater say a 500W or less timed for an hour a day total it would cost roughly the same per day as one boil of a full kettle.

Hi,is this toilet inside or outside,a building?

downflow heaters now come with 30 minute cut-off timers. (I just fitted 1 this morning). pricey though@ £54. apparently it's a new building reg.

Inside, about 2m x 0.9m

A room thst size,indoors,is made for underfloor heating,either wet or electric.
You could probably retro-fit a mat,depending on floor type,and have it on a sfu or even a lead.
It's going to be cheaper to run,not obtrusive,and it warms all above it.....which means no glute-shock?

Infrared, ceiling or wall-mounted heater, on a stat.
Slim, unobtrusive, cheap to run.

I would consider a towel rail, keep the room cozy plus keep the hand towel dry. ( 2 birds with 1 stone)
