I have a baxi bermuda back boiler running five radiators
Two small rads, two medium and a large one.Now I have flushed and drained the system, it seems to run well as I am unable to hold onto the bottom of the rads for long without being scolded..:0)
The system is 25 years old
I would like to add an extra bathroom/shower room rad which I am told needs to be large.
There is a plate on the fire front that says the system outputs 20,000 btu's.
To find out if I can successfully add another rad, do I just add the btu capacity of each rad to see if it is within the capacity of the system? Or do I have to take heat losses , pipe runs and all sorts of other factors into account just as much? It seems that the system would be able to cope.
Also, is there any way I can improve3 the efficiency of the back boiler by cleaning it out or something?The flame seems the right coilour (yellowiish) and the system works o.k.
A baxi bermuda back boiler will run more than the 5 radiators you have, I have worked on many Bermuda's in houses that run 8 radiators.
That 20,000btu's - which equals approximately 5.8 kw will be for the gas fire only.
The boiler data badge is under the fire on top of the plastic cover over the thermostat, or Bermuda 551 or 552, it will be on the combustion chamber cover - the boiler will probably be about 50,000btu's+ depending on model.
Cheers for your advice htg..
Your advice makes complete sense.
It also may explain why I have had several pumps go over the last 15 years.Probably due to air in the system which I have now corrected ..
I best get my crow bar ready for some floor board lifting,...
