So I bought a wood burning stove with a back boiler on it.
Gosh I thought that was a great idea... just pull out the old fireplace and bingo... a few pipes later and amazing heat throughout the house...
Well it hasn't quite worked out that way, when I looked online and saw the complexity I decided on a plumber but plumbers around where I live aren't too keen on trying to match these into existing systems, they like the new builds but not the rebuilds.
So I have pulled my plumbing apart, I've pulled the fireplace apart and its February and I have no heat.....!
Hoping you guys can help me out here... Ive taken what I have found on the net and come up with this schematic.
1" copper from the oil boiler to a junction of T's, Non Return Valve on the flow and pump on the return.
1" copper from the wood boiler jioning the T's on the opposite side to the oil with Non Return Valve on the flow and pump on the return. On the boiler side before the Non Return Valve on the flow and the pump on the return, 2 x T's take a gravity flow to the dual coil cylinder and expansion tank.
After the flow and return junctions of T's are 2 x motorised valves for ground and 1st floor radiators.
The flow and return to the dual coil cylinder is allways open.
Piping after the junction of T's is a mix of 3/4" copper and qual-pex.
Relays and switchs will mean only one system works at anyone time, ie when the wood boiler heats sufficently it kills the oil boiler and when it cools the oil boiler kicks in.
My question is will this work and have I missed anything? Injector T's where mentioned to me but I don't know if I need them?
Also a presure release valve, where should I put one?
Thanks for reading...
