Viewing a thread like this gets you a bit jelous if you aint got one:sad:

 

Wait till I,ve sussed uploading pics,I,ll post apic of my double door Hunter. We keep it alight 24-7 for up to aweek at a time. One initial payout then years of free heat. You gotta have one. Not trying to sound smart, just trying to save you a few bob.

Supposed to.

 

I did the first 2 metres in copper, then onto the plastic. Once the circulation pump was working it ran fine. To blow a hole in plastic pipe you need a fair pressure and about 120 degrees C, which is a tad warmer than i like my radiators!

I know what you mean but if you have a high "head" of water it will be at a higher pressure and therefore water will still be liquid at 120 degrees, a bit like a pressure cooker so you may not hear it intill its too late. Its ok untill you get a power cut!

Bob, have you got some type of pressure valve on the heating system. A friend of mine has been told he can't do it off a back burner which I am sure is boll****, not true!:thumbdown:

 

do not really understand the question but was fitted by a proper plumber and is protected against problems such as power failures

Ah, this was on a closed system, like you have with a modern combi boiler, and I always ran it on quite a low pressure, just under 1 bar, with an expansion vessel to iron out the hot/cold fluctuations.

 

I think the key is to have plenty of radiator as a heatsink in the system so it never gets too hot, and always run the circulation pump fairly high so heat doesnt build up in the back burner. Probably makes the log burner less efficient though. If I ever want to heat a whole house with a log burner again, I will be looking into warm air circulation rather than a radiator system.
