pipe stat location.

Tuco88

Hi i am only asking if this is correct, my pipe stat for my stove is located on the return pipe set at 40 degrees. It brings on my pump located on the return pipe on the rads circuit. The stat is not located nearest to the stove but the hot press about 3m away(not practical to run cable over) is it not ment to be on the flow? I was told it was better for preventing boiler corrosion.

I'm not an expert on stoves but the stat should be positioned on the flow pipe as near as possible to the stove.

Correct. And set to 60

Ok, I only ask because next door have it set up like you said but a different make stove, My one is a Hunter Herald 8 great stove too, I just want to make sure my one is working at its best, it shows on the manual too that a stat "low limit" on the return pipe? I asked the plumber and he said they way its set up it will allow the hot water cylinder to heat up and not be starved from the rads.. I will post up a few pics when i get the chance, I was only worried that if I moved it I would suffer "boiler corrosion" or something?

It does heat the water great, but can take time to get the rads warm, maybe 3-4 hrs. I burn coal and timber.

Sounds like another cowboy plumber. On the flow within 500mm (general rule of thumb) of outlet of the stove. Have it accessible of possible and set it to your needs. 55/60 is usually ok. Best of luck.

All respect to the plumber hes far from a cowboy, I moved the stat on to the flow to see what its like, moved it up to 60 rad heat up very fast but I have hardly no hot water at all. Contacted the plumber he came out to see, he adjusted the pump speed it looks to have improved it allot its a long cottage. He explained why the stat is there, said when the hot water is gravity and the rads are pumped the stat should be on the return so the hot water can heat up, he dropped the stat down to 40 to compensate for the distance from the stove because we were not able to put the stat there.

Its our first stove so.. were still not used to it ha.

Thanks very much tho.

Something ses to be off. If the stat is on the flow and set to 60 then the water in your cylinder should be 60 degrees. Putting the stat on the return is nonsense to be honest and is probably covering up for poor installation issues

I would agree with dtp. There is something wrong with your gravity circuit. If it is thermosyphoning properly, then your dhw should be @60C, assuming your stat is fairly accurate.

Ok, I will get another plumber to have a look to be sure. Just a question tho, why does it also say in the manual to have it on the supply pipe to the stove at 45. degrees?

My stat is not close to the stove, the stat is located less than 3m away in the hot press, surly you could compensate the distance by adjusting the stat?

Thanks again, will let you know how it follows up.

on a 4 pipe installation would it not be set up with two stats
one on the primary return set around 40-45 to bring on the pump for the rad circuit when the cylinder coil has heated, and the second one (high temp stat) on the primary flow set around 65-70 to prevent boiling/overheating if the stove is overfired and the water heats quicker than the thermosyphon can handle

On the Stanley Comeragh it says to put it on the return.

You are the one that derailed this thread, did you not find my post about the location of the pipe stat on the stanley range a professional reply?

Lads,
I always in the past put the stst on the flow, but lately I've started rtfm's and most state for stat position on the return as this helps with thermal shock and boiler co densation.
I've been fitting on the return ever since setting at 35*c. With the stat just below the injector tee.
