i havn't got a link but this is what is says in the city and guilds text book..

'' install an automatic bypass valve where manufactures instructions advise installation of a bypass.. TACMA does not recommend the installation of a bypass valve if the boiler is of a fully modulating type''..

im guessing its because the flame dies down when its reaches temperature, there for the bypass wont open.. but thats only my opinion.

Bypass is on pressure from pump me old chuff a. The idea is that the bypass opens as other controls on the circuit close down. Allowing a constant flow through boiler. If you don't cool the boiler after the flame has gone out it will Look like a scots bonce

all part of building regs now as well

myself personally,, i would fit a bypass because it just makes scene, also the bypass would make the system more efficient as it would, interlock quicker or turn off quicker, but then they say not to fit them if the boiler is of a modulating type,, its all a bit confusing,, maybe some can explain this modulating thing to me. thanks

 

[Ermintrude]

Is this not a modulating pump? Not a modulating boiler?

 

[lame plumber]

modulating pumps are fine till you switch em back on manual as they fail to work properly on an old system full of muck and then is when you need you bypass again

it actually says boiler but they could be referring to the pump,, i mentioned it because, i thought some1 could shed some light on the area 4 me. thanks
