23 rads and one kitchen hot water supply plus two basins in toilets. Had an old Concorde system boiler which gave up.
Two zones supplying two large rooms 50' x 12' x 24' each. Local heating company recommended Nevien 42kw combi
boiler and things went wrong after that.
The installers have made excuses that the building needs the radiators, which worked fine before, at a cost of £1400
or they would disown the installation with much chattering of balancing the system etc. I have done that and vented a
number of times. ( I am an old fart who has worked and maintained many systems, but not the gas.) My problem boilers
were Worcester Bosch. I learnt to replace PCB parts at 30p from Maplins instead of paying £120 for a new board.
The boiler keeps blowing seals and is not happy with the system pressure.
Landlord was advised to install another pump as the heating took four hours to circulate to the lover zone radiators but
not to the extremities. The boiler has to lift the supply to the roof space and is a 40mm pipe work.
Its a mess and the Publican has lost customers owing to the lack of heating.
He has appealed to Nevien who have been helpful and initially said that the 42kw boiler will cope with the system.
They have since changed their position after their engineer changed the seals and said a system boiler was the best fit.
The original tank is still in place.
Nevien seem to be putting pressure on the local installers to sort things out but they are pratting around and making as many excuses
possible to avoid the issue.
Could you please advise me regarding the room volumes if a combi boiler should provide the heating system?
