Hi all.
We are looking into the logistics of a wood burning stove with a back boiler (to be used with a thermal store)
We have an inglenook fireplace in the lounge.
I have a question. As the thermal store would be in the room above the room containing the wood burning stove, Is it allowed to run the flow and return pipes through the register plate? The register plate is about 2ft by 5ft.
There is currently a 12 inch metal flue liner (theres a pub style gas fire currently). There looks to be enough room to fit a proper double lined WBS flue pipe through this 12 inch corrugated aluminium liner.
The chimney stack is half into the house and half outside if that makes sense.
The flow/return pipes would come up vertically behind the WBS, through the register plate, traverse diagonally between the ceiling - upper floor void, and then vertically into the thermal store.
If pipes through the register plate are not allowed, that would mean running the flow and return pipes up the interior walls of the lounge which would not be aesthetically pleasing.
