Hello,
I am about to get the attached Viessmann 100-w heat only boiler with pump and diverter valve.
Current boiler - Non Condensing
System - OV, CH only, no DHW
Feeder Tank - Yes
Expansion vessel - No
Pressure Relief Valve - Yes
Filter - No
RF connections - 22mm
NG pipe - 15mm from meter to existing boiler
Radiators - 10 (not all of them in use, will be using 6-7 in winters)
No TRVs or thermostats on rads
No internal controls or weather compensation yet.
FY 23 gas consumption - 19000 kwh
I live in a hard water area that is why I have chosen SS HEX.
Reason for change - oversized 26kw boiler with efficiency of <70%. consumes ~10kwh for 6.5kw load on CH only. A boiler with good modulation required.
This would be shipped to me from London to Pakistan as I couldn't get a smaller boiler 11-13 kw in my home country.
Questions = What else do I need to get with the boiler for installation in my home country?
Thanks in advance.
