Hi - Hoping someone can give me some advice on a problem with our CH system, which is struggling to heat our 2nd floor loft-conversion room of our victorian terrace.
- Boiler is only a year old and heats the rest of the house OK.
- The rad in the loft room is blead and gets an even hot temperature top-bottom.
Even with all other rads 'off' it doesn't make much noticeable difference.
If we let the room temperature drift down during the day (e.g to ~16C) it then takes ~4 hrs in the evening to rise up just 1.5C to 17.5C.
Once up to temp it's better - a half hour of 'boost' every couple of hours through the night at the moment (our baby daughters are currently in our room, so we are keeping up the night-time temperature).
Alternatively if we tried to keep the room temp constant 24hrs (to save the ~4hr re-heat, the heating would be running probably 18 of 24hrs.
Room size:
- 3.6m x 5.4m,
- ceiling about 2.1 m across the dormer half, sloping across the pitched half
- Exposed to the south (pitched) and north (dormer)
- Neither neighbour have a loft conversion, so I guess 4-sides exposed!
- Using the rad calculator at http://cultfollower.net/radcalc2/BTUcalc.htm it gives about 5000 BTU but how do I account for the sloping roof?
Does 5000 BTU a reasonable estimate for this size & type of space?
2/ Is the radiator hopelessly undersized for the job?
- The radiator is apparently a slimline. It was fitted before we moved here so all I know is:
- 1000m wide by 600 high, single panel with 1 set of fins (It does look slimmer than a normal single panel)
Can anyone suggest what the BTU is likely to be for a slim panel this size?
3/ Any other suggestions? Or is it just a lost cause because it's a loft room?
Thanks
