Went to a large domicile today.
Bloke knew he needed an 837 to run alongside his 31kw boiler which heated his UVHC. The two systems were separate and needed to stay that way.
His u6 gas meter on a 22mm supply wasn't an issue nor was his fully open bypass.
Spent a long time expressing my concerns on the system design. 170m2 underfloor and lots and lots of rads. Heating load is apparently 47kw ish and wondered why house always cold?
I Said he only needed a 630 linked to other system boiler on a LLH giving 61kw max output. 5.67m3/hr
28mm supply 40l external expansion and a 32/120. Think he thought I was taking the pizzle. As two other installers said a 837 would be fine alongside his 31 kW. 6.33m3/hr so not undergassed! But hey might still get job?
What do u do when u have jobs like this? Said I wouldn't be installing an 837. Would do a straight swap on a 630 plus 28mm gas re run. But wasn't responsible or even to be asked about system and why it didn't work..... My contract was a heat unit only if he wanted it and asking as it came on and heated that was end of our responsibility?
Thoughts?
