Hello there,
thanks for taking the time to read this. Bit of a tricky one I think. I got called to a biomass boiler installation about 2 years old (not mine) where the central heating pipes inside the house are banging when the water temp at the boiler gets to 40 odd degrees. It is a 40kW herz boiler and there is a 4000l (yes, that's 4 thousand!!!) buffer vessel which is obviously between the boiler and the central heating.
What's confusing me is that the banging only begins when the boiler itself heats up but I would have thought that the effects of any air/unsupported pipes etc. would comfortably be absorbed by the massive buffer vessel.
the customer has kept his old oil boiler which he is using while we come up with a solution. This boiler bypasses the buffer straight onto the central heating and he has had no problems with it.
If you've got any ideas on this please let me know cos it's got me stumped!
cheers
