Opinions on boiler stove connections

dersawazzie

Hi all , I'm looking for your opinions on what way you would connect a solid fuel boiler stove's water connections. My dad has bought one without any installation guide , he says it is approx 12kw input (no data badge). It has four 1" connections on the back of the stove , which I was going to connect to a gravity circuit DHW cylinder (to be used as a heat sink) and a small radiator circuit.
My plan was to use all four connections but bring the returns in across the boiler i.e the gravity return will come in under the pumped flow and the pumped return under the gravity flow so no injector tee used. This is where your opinion is welcome , anyone done it this way or have you found combining the flows and returns using an injector tee more effective?
Any replies most welcome thanks in advance.

The way you have described it is perfect.

Is it possible to conect a multi fuel boiler stove with 3/4 inch pipes?

It is possible but not reccomended. Minimum of 1" especially in hard water areas and gravity circulation is also much easier achieved in 1".

But if 3/4 inch pipes work with stanley oil and solid fuel cookers why don't they work with stoves?

Stanley oil and solid fuel cookers should be piped in 1"

Of course it is allowed. Ask your plumber/heating engineer on how to do that....

@ plombier:

You said above:

Any references ?

Thanks, plombier.



Does Waterford Stanley not produce any pumped and pressurised oil or solid fuel boilers? Only boilers suitable for gravity-run or pumped vented/open central heating systems? No pumped and pressurised boilers ?

Interesting I have a stanley oil cooker that was installed 13 years ago that is fitted to 3/4 inch pipes. It doesn't heat the house very well would the 3/4 inch pipes be the cause?

I doubt it as it is a fully pumped system. Stanley say the 1" pipes are necessary, so to get it commissioned by them you need the 1" pipes, I think their reasoning is that when it is being used just for cooking that it can dissipate excess heat from the boiler by gravity but I'm not sure if that's it.
