at the moment i have 5 radiators 1 double and 4 single panel. they all are 40 odd years old , i want to relace all with double panel ones. would my boiler cope ok ?. it is a condenser boiler and the tank in the loft is open vented. hope some one can give me any advice. thanks.

Yes it will.

Perhaps consider a flush before fitting new radiators I would imagine some sort of sludge.

i have flushed recently and cleaned the magna filter.

i was thinking of buying the kudox rads from screwfix ,they have a 15 year guarantee. are they a good buy ?

 

[ShaunCorbs]

there ok but i would ignore the warranty, make sure you inspect them for damage tho

ok, thanks.

Ignore because they're not likely to honour it, or because warranties on rads not likely to be required?

both as they will want system water tests and they will blame it on corrosion

If your house warm enough on single rads theres no point changing them to doubles , just keep them as singles .

i thought doubles were cheaper to run [in the long term ]

On what basis, it’s based on heat loss and correct sizing

You are paying to heat more water , thats your answer

The OP may be thinking of the case where the 'correct' sized radiator needs 80°C/60°C to heat the room but the oversized replacement can work with 60°C/40°C. The latter allows the boiler to work in condensing mode. Correct in theory, but in practice many 80/60 systems have subsequently been double-glazed, etc. and are sufficiently oversized for the return temp to be below 50°C most of the time anyway.

Good point a definite maybe

i see, thanks for all your help and advice.

The other thing to weigh up is the cost of new rads throughout compared to your annual gas bill, you will probably find that it would take decades to pay them off with any potential savings. Even from an ecological perspective, any reduced co2 emissions are wiped out by the co2 required to manufacture and transport the new panels.

so best to replace with single panel i guess

I would suggest you have a plumber in to properly size your property and calculate the heat loss

good idea

 

[townfanjon]

good idea

It is , if you boiler is the old non - condensing boiler ask the plumber / heat engineer to size for a condensing boiler .
Obviously if you are condensing now is just normal stuff .

i have a condenser boiler. i will get someone round. cheers for help.

You really should just do heat losscalculations for the rooms. It’s very simple to do, just go here: Heatloss Calculator | City Plumbing Supplies
