How fast do you think a 2W fan heater will heat a room to, say, 20C from
10C or 15C? I suspect it's a LOT longer than the time taken to go to
the loo during the night, ever for an hours worth of bowel evacuation.

When my central heating was down, I found a 3 Kw fan heater warmed up my
pretty large bathroom very quickly.

Apart from a central heating radiator, which we can't do (and even if we

This query has been prompted by a rather unpleasant situation. The ceiling
height in our (small) bathroom is 7ft 6in and we currently have a fan heater
mounted on the wall at about 6ft high. The fan heater starts off at 2kW and
when IT thinks it's warm enough, IT switches down to 1kW automatically.

At about 3am one very cold morning I was woken up with a dose of the runs and
spent about 50 minutes to an hour sat on the loo. Of course, we all know that
hot air rises, so up at ceiling level the room was lovely and warm, so much
so that the fan heater took it upon itself to cut it's output down to 1kW.
Meanwhile, at 'sat on toilet level' I'm freezing me nads off and shivering
for England, as well as suffering the squits!

The fan heater has, just this very morning, gone to that great bathroom in
the sky and I'm wondering what we can replace it with that will allow heat to
get down to toilet height in order to avoid such a situation again in the
future.

I think you have the best possible setup, and it's exactly what
I install in bathrooms even though they have central heating.

Downflow heaters in bathrooms do need dust cleaning out though.
I wonder if your dead one had become blocked with dust, reducing
the effect of the fan getting the heat down to the floor, and
raising the output temperature due to reduced air flow causing
the output heat to convect quickly back to the ceiling?
I switch mine to operate only at 1kW anyway.

They do that. There aren't many truly thermostatically controlled fan heaters suitable for bathrooms.

I use a 500 watt t/stat controlled convector at low level. Warms the room adequately and doesn't run away with the lecky bill if left on accidentally.

I have a lifetime bowel condition. My advice is to always put a jumper
or something on when you run to the bathroom, and also keep a dressing
gown in there.

Good idea about the jumper Bill. I had my dressing gown on and ended up
wrapping the towel around myself too - it was bloody cold!

Also, always take your phone with you in case you take a turn for the worse.

Afterwards wash your hands and anything you've touched very thoroughly.
I use alcohol-based hand gel as well as washing.

Then make sure you drink plenty, otherwise when you wake in the morning
you'll have a headache due to dehydration. I have tea making facilities
upstairs.

You are fighting the laws of nature here though. All heat is going to rise
after all. I guess the only one that can warm other parts of the body will
be heated seats and floors.
Eventually, though lower down will still be cooler than higher up unless
its a complex air recirculation system, probably a bit overkill for a
bathroom, but it begs the question, why is your house so cold? Are there
draftee bits?

I have a 1 bar fire very high up in my bathroom and yet I don't seem to feel
the cold as there is just one air vent I can close to stop the wind a
blowin.

Part of the problem may be the British habit of turning off the central
heating at night, even in the coldest weather. Though I note the OP's
CH doesn't even extend to the bathroom, and he appears to want this
situation to remain permanent.

Yes I'm firmly of the opinion that it is folly to turn off central heating
at certain times of year. Leave it on all year round and let the thermostat
do the job it's designed for. You can get cold evenings in the summer as
well as in the winter. And keep the heating on until everyone's gone to bed,
if you are one of those people who likes their bedroom to be colder than
normal room temp (my wife prefers to sleep in a cool room with lots of
bedding, whereas I prefer a warmer room with less bedding, so you don't end
up with a warm body but icy-cold head and face.

CH radiators (*) seem to do a good job of keeping bathroom warm, so maybe in
the absence of CH you need a heater that mimics a radiator - a large panel
that gets up to about 80 deg C, as opposed to a very small heating element
that gets red hot and sends out radiant heat (often in just one direction)
but does little to warm the air in the room.

(*) Which actually do most of their heating by convection.

I quite agree. Our CH goes off at night for a few hours, and during the
day if we're not in. The house has enough thermal inertia to cope -
normally.

But in very cold weather, it gets too cold and takes hours to warm up
again. At that point, it stays on overnight. Usually just a few nights
per year.

+1.

Due to the recent unseasonably (for London) cold weather, my dual fuel
monthly payment has been increased by quite a bit. And I did unusually run
the heating overnight on a few days.

I never turn our heating "off" as such, but it runs on a programmable
stat, and spends some periods of the day at its "set back" temperature
(15 IIRC). Its exceedingly rare that the place cools enough for it to
kick in during a setback period - perhaps on a very cold windy night.

Isn't that a heated towel rail in the picture of the bathroom?
Or maybe it's not connected?

Central heating not on during the night?

How about leaving it switched on all year round and using programmable
thermostats and zoning?

Can't afford it? Then improve the insulation levels.

If the other residents don't mind then leave the door open and heat the landing
or hallway.

Best heater for a bathroom? One that keeps the room warm for when its going to
be used. With lots of decent insulation, maybe some solar gain, a closed door
and a small source of heat like a towel rail you could possibly keep the room at
reasonable comfort levels round the clock.

This is the only rational way to do it. Unless you are able to predict
an hour before you will need the bathroom and have a remote switch.
This must be unusual.
