I am considering getting a Vaillant system boiler 612 and am seeking some info on gas pressures & hot water system
Can some one tell me what gas pressures is required:-
1. at the gas meter minmum
2. at the boiler minimum
3. what gas pressure drop is allowed for boiler to be operational
4. I understand the gas pipe diameter from meter to the boiler is 22 mm.Is this sufficient to operate the boiler
5. On hot water supply, I wish to retain hot water cylinder which is fed by water tank.
6. I have 6 radiators ( about 5ft x 2ft) . Would 612 boiler be adequate.
Comments from pros very much appreciated.
Thank you in advance
