Folks, need some advice.
I have a large, long "bungalow" with a Vaillant ecotech plus 630 at one end driving a closed/megaflow type system. It's a long way to the other end.
We have mixed heating types: Traditional radiators, underfloor for the extension and polypipe overlay for the sitting room.
The Vaillant struggles often giving an F.20 error (especially when just heating the water cylinder in summer).
A plumber suggested we consider installing an intermediate heat exchanger with separate pump next to the boiler separating the boiler from driving the system and allowing it just to heat water.
Unfortunately, I lost the plumbers number and cannot remember what the type of system is called or find any reference to it on the internet.
Q:
What is this type of system called?
Is it a good solution?
No, I can't move the boiler to somewhere in the middle of the house
Cheers,
Tim
