If its on an f/e tank, then its a regular heat only. It only becomes a system boiler if it has the pressure vessel inside the boiler.

Dont have the lpg cost to hand pete, but I will get someone to look it up and call you tomorrow.

Do you have a preference for brand? Main is probably most cost effective (rebadged Solo) but I am not sure if they do it in LPG.

I always thought a system boiler had a pump in as well?

It usually does. But its the pressure vessel that makes it a system boiler - they always used to be called "sealed system" - we just dropped the word sealed.

Most manufacturers made their system boilers by taking a combi and stripping out the unnecessary DHW components, which is why the pump was usually included in the boiler. Once you get in that habit, there is an expectation that there will be a pump in a system boiler, so now even the ones designed from scratch tend to include one.

Ok tommorrow I'm doing a heat only but they want it converted to fully pump with 2 . Two prt valves. I've never done this before feel really out of my depth !! Any stupid guides ?? Help ect ??? Pictures guides please

[lame plumber]

make sure its suitable to convert, ie has overheat stat already.

 

[P J F PLUMBING]

It's a grant job all been looked at and got the paperwork that says convert to fully pumped incorporating 2 port valves I haven't seen it I'm going there in the morning I don't want to look thick and say I don't no how to do it ?? The wireing getting done by a sparky but I have to change the boiler swap for swap and convert to s plan. Never done one before I usually fit combis Ahhhhhhh

Conversion to fully pumped doesn't need overheat stat does it? I thought that was for a conversion to sealed system?

 

[Nostrum]

What boiler doesn't have an overheat stat these days?

 

[Ermintrude]

A pump? On DHW cylinder..... Not going to catch on!
