central heating

[shad123]

can i just add 2 radiators to existing (wet) central heating system thanks




i now know it depends on my capacity of my boiler, but what should i be looking for on it? and how do i work it out to the ratio of radiators if you understand what i mean....thanks

It depends upon the capacity of your boiler

Although ideally the decision should be made on the capacity of the boiler, radiator area, ambient temperature and heat loss from the house, you can make an empirical judgement by monitoring - on the coldest day you can find - the proportion of time for which the boiler fires. If the boiler is already firing for 90% of the time, it will surely struggle to cope with extra radiators. If it only fires for 30% of the time, then there will be capacity to accommodate extra radiators. Between these two extremes, it's a matter of judgement.
