Could you not arrange a single zone to be on for that bedroom, use a wireless thermostat and take the thermostat up to bed with you?
I have to ask why your house/bedroom becomes so very cold during the night? I usually run the general house temperature at 20/21 C and with no heat input, on a freezing night, my indoor temperature rarely falls below 19C before next morning.
williamwright pretended :
My indoor temperature only falls by a couple of degrees from 20/21C of the night before, by next morning, even when its freezing outdoors, with no heat input. If I feel chilly a few hours after getting up and before we get any heat from the sun, I might turn the stat up to
20/21C- it will have met that and the boiler output ramped down within 30 minutes.I have several tons of extra stone in the house, which I call a heatstore. If the house is left a full week in freezing temperatures, without any heat, it can require several hours of heat input to get it back to a comfortable temperature.
Its a 3 bed semi, CWI, well sealed with DG and doors, insulated loft, insulated roof. The entire house is always heated and all waking hours. My gas heating and cooking bill last week was around £8, no other form of heat.
Might depend on the insulation your house has. This one, built in 1911, doesn't hav cavity walls. Heat leaks
Caecilius submitted this idea :
If an oil heater is used in too large a space, set on too high a temperature, then they will cycle on their over heat stat. You are basically asking them to do more than they are capable of doing.

Over 4:1 here. Heating the rest of the house would probably reduce the heatloss from the bedroom, as well as having the benefit of the house being kept warm for next day.

Then you have my sympathy, part of this place (utility) has a two 9" none cavity walls. It makes it very difficult to keep warm.
The simplest solution to this might well be to find an old style electric drill speed controller or build one from scratch and use it to provide PWM modulation of the output power of the heater under control of a remote thermostat.
I'm quite sensitive to cold, and seem to be getting less cold tolerant as I get older.
My bedroom will go below 19C without heating on a cold night though. Not sure why - maybe poor insulation.
Why not install a split aircon in the bedroom and enjoy warmth in the winter and cool in the summer?
Heating a building is about energy in and energy lost via conduction, radiation etc, if you have a simple thermostat controlled environment it probably is the best way to heat a home, if you are properly insulated etc.You are not constantly trying to reheat a cold house and thus spending more money.
That's a good suggestion, although it's a much bigger project and I think heat pumps become much less efficient when the outside air temperature drops close to freezing.
Not that difficult to dryline just those two walls with insulated plasterbaord though. Being a utility room, I presume you don't have fancy coving or decor to worry about ?. One day we are going to get a Labour govt again and those home- sellers reports will be back with a vengeance.
If it has cavity walls, where is this stone ?.
