to calculate if one radiator can be added to CH system

[hussy]

Hi all
I have a conventional open vented CH system with x9 radiators in a x4 bed house. The living room has one radiator and other areas of the room are cold. I want to add a radiator to this room.
How do you calculate if one can be added and is there a specific calculation/calculator to figure this.
I guess you take the width/height measurements or your radiator and note if they are single/double panel etc.
What else comes into play in the maths of this.
By the way thanks to everyone re my last thread, all fixed now.

if your diy, then add another rad to match the one you have , on an old ov system youll probably have more than enough power in hand on the boiler not to have to worry.

hi
the house is 15 yrs old, oil burner in outhouse.
I have a double panel rad 1/2 size of existing rad in living room, was going to install that from a branch off opposite a hall rad.

I personally would put the heating on full till everything melts. If it struggles and everything gets just warm you cant do it. If it boils the cat then you got the heatage!

I have never done it though so wait for someone more sensible there is a calculation based on heat output of the boiler KW i believe.

Q'est que???
ha ha ha that was one mighty weird reply, tell me more on the calculation!

there is a proper way to work out heat loss per room using U values and calculations. Also there is a mears calculator but this is not as accurate. Most engineers jus use their experience to know what size boiler a house requires. but this all depends on if you got double glazing, filled cavity wall or jus a cavity, roof insulation, floor insualtion and air changes.

like i said if your going to diy it then off you go, wont be a problem.

the CH system has been thoroughly clean and protected. In the same houses in my street, they have x2 rads in their living rooms, which is why I was thinking of installing another one as I have only one.

Old plumber you are a bit of a sarky sort but I love the larks.
