Fitting another radiator.

It has two rows of fins. It's the door to the hallway.

Aye, sorry. I have carpet and then under that it's floorboards.
 
what size in the room ? uncluding any other room attached without a closing door next to your living room or radiator ? how many outside walls ? how many windows ? are they double glazed ? whats the hight of the room ?
 
Main room: 144" x 162" x 103"

Side room: 108" x 68" x92"

1 outside wall, one wall sides onto a communal corridor though with no heating. 2 windows, double glazed.
 
living room needs 8270btu rad, classing the room as having 2 outside walls as one going out to corridor.

1983btu's needed for your kitchen, if it doesnt have a radiator already and the door between kitchen and living room isnt there..

so total that minus the radiator you already have in the living room which is likely to be 5500btu then you need 4753btu more heat in the living room which should cost you 55 quid pluss fittings and fitting
 
if you clear the room and have the radiator and valves ready for a plumber and you get it done in plastic pipe, it wont take him much longer than an hour, so guessing he'd use his own pipe, it shouldnt cost any more than 80 quid to him, pluss the radiator 55

total £135

this is if everything goes smoothly, their is a clear run for the pipes and the pipes that he could tap into are suitable

If that radiator is working properly and its not heating up the room i doubt two radiators will do much, youll just be loosing twice the heat. You need to find out why a perfectally good radiator isnt heating up the room.
A plumber will be only too happy to agree with you in saying that you need a new radiator because he will make money out of you.

If the radiator is too small and you dont have the space to put a bigger one in then you could then move the radiator location to another place in the room - somewhere there is space for a larger one. Having two radiators is a mad idea.

Why is having two a mad idea? Many rooms have two radiators... My radiator isn't giving out enough BTU/hour to keep the room warm and isn't a "perfectly good radiator" for the size of the room. I therefore need more BTU's. A second radiator would give me this.

Granted, insulation may be a problem but I'm not sure how I can get insulated as I live in a old tenement with brick walls. If there are some people that know about insulation here I'd be happy to listen.

What on earth are you on about? :confused: Many rooms have two Rad's my living room in my last flat (3 yrs old) had two rads. It will cost more to relocate and buy a bigger rad for the room than it will adding in a 2nd small rad to give the BTU.

As the OP says, Bar cavity wall insulation which will help he is still stuck with a RAD in the room which isn't giving the BTU needed for the size of the room.
 
My living room is 8m x 4m and has an open stairwell and landing, so I lose a lot of heat that goes upstairs or into the kitchen. It's also solid brick so I can't cavity insulate. Therefore I have two decenct sized radiators. I ran with just one for a while whilst renewing both rads and I can confirm the room is definitely colder with only one rad working!
