Need advice on plumbing a vented heating system in a difficult building.
Main building is 490 year old grade II lsited thatched stone cottage. Fitting a boiler into it is nigh on impossible ( walls 2 foot thick and minimum clearance between flue terminal and thatch cannot be achieved.
A single story brick kitchen is attached and this is where the boiler will have to be located to achieve clearance from the thatch.
Header tank needs be in cottage to achieve necessary head.
The problem is the only route for pipes from kitchen into the main building is less than 2 feet above kitchen floor level. ( stair case inside cottage prevents anything higher )
Pump needs to be under the boiler to feed second hot water tank and radiator in the kitchen.
Which is the best ( compromise ? ) method to connect feed and expansion into the flow and return ?.
A pressurised system is not a prefered option.
