A (if) CH system has a very high head loss due to improperly sized pipework and long runs and possibly partially blocked pipes and requires a UPS2 pump running at its 8M head to feed 21 rads with a theoretical output of 25kw at a 20C dT.
A fairly old Vaillant 438 boiler is being replaced, the...

I don't work now due to being ancient. I looked at a 'Range cooker' fired on kero. It had a slow leak that turned into a bad leak in a month!
It had a welded fabricated boiler. I've seen such heat exchangers leak within 7 years from new. No wonder the Potterton heating production manager said...

I know when installing an expansion vessel it must be connected to the system without any isolation valves. How is best to pipe in to the system so it can't be isolated. In the diagram below a potential way I was going to pipe in to a heat only boiler. It could be isolated by isolating the...

I want to have a completely separate CH boiler and DHW boiler.
DHW easy enough, nothing to consider really, just plumbs to existing pipework
CH option boilers are heat only or system.
