Which side of the boiler does the circulating pump go?

My DIY book tells me to place the circulating pump after the boiler so it pushes hot to the rads. My boss who is usually knowledgeable on these things says it it should go before the boiler pushing the returning cold water into the boiler. Which is collect?

A solid fuel stove with back boiler.

It all depends on the way it is plumbed and if there is an oil burner aswell.

I'm afraid if you need to ask you shouldnt be touching it in my book.

It's not safe to run an oil boiler on the same system as a back boiler, so no there is no oil burner.
If questions are not asked, how is anyone to learn.

Well maybe you should ask how to plumb the oil and solid together because its done every day with the correct fittings.

I wonder why you think it isn't safe
Maybe it's the same reason you don't know we're the pump goes most pumps on solid fuel only would be after the thermostat. But plumbers have there own way and theory.

You go to Collage, you do the coarses, then you'd not only know the flow and return on a stove but as the man above points out, how to combine it with oil without killing yourself and neighbours.

Solid fuel boilers are not a DIY job solid fuel boilers are dangerous if not done correctly, and every installation is different in its own way. There seems to be an opinion in Ireland that you can just throw in a solid fuel boiler away you go.
There are plumbers that wont go near solid fuel boilers because they are not as straight forward as and far more dangerous than gas or oil boilers if not done properly.

From the questions you are asking please please do not try to install a soild fuel boiler, there is a lot more to them than just joining a few pipes. They can be far more dangerous than people realise.

OP, please take heed of the above posts.
I've seen the result of a badly installed boiler exploding and causing thousands of euro of damage.
Luckily the only occupant of the house had gone to the shop minutes beforehand.
The boiler was plumbed by a relative of the owner(first year apprentice plumber).

When serving your apprenticeship, you learn why, as well as how, to do a job.
Thats the difference between qualified tradesmen and us diy'ers.
