Hi,

I have a new kitchen/dining room and I am trying to decide how many
radiators to place in this room.

The room is L-shaped (forgive the ascii art!) :

|--- door----| ^
| |
3m | +w
^|---wwwww---| dining +w
| +w 5m
3| |
m| Kitchen |
| |
| |
V|-door-------------------| V
| -------- 6m ------ |

(w=window)

Therefore I estimate that the floor area is 24m^2 and the room volume
is 55m^3. From my heat loss calculations I guess that a 3 kW radiator
would be sufficient.

My question is would 1 rad be enough or should I use 2?
(The + symbol shows where I would place the single radiator
below a window).

TIA, W



I have a similar sized room, and fully insulated to modern standards it
takes about a kilowatt and a half to heat it.

If its an old building, maybe up to 6KW.

Your 3KW figure is probably a good answer. Over radiatoring does no harm
apart from te asthertics and initial cost. Assuming you have some form
of thermostatic control.
