We have an Ideal Minimizer (50,00BTU) and a Heatrae Sadia Megaflow CL170. Both are 12 years old. The boiler has always been unreliable and needs remedial action/rebuilding about every nine months - this is done by British Gas.
The house has 19 radiators and the system really struggles to provide hot water and central heating during cold spells. I know nothing about the technical stuff but I think the radiators will not come on if the temperature of the water in the Megaflow is below 57 degrees and if someone has a shower the temperature in the megaflow goes well below that for ages (maybe two hours) and if several people shower (separately) then the "hot" water becomes cool and we can forget room heating for the day. I suspect that the whole system needs to be replaced. However, ...
We are going to replace the boiler and a plumber has suggested a Worcester Greenstar 30 combi boiler. The write ups sound good but my basic question is: will the new combi boiler work efficiently with the Megaflow? Will we see any improvement in terms of hot water and room heating?
All advice, hints and tips gratefully received.
Cheers, James
