hi all ,
i want to move a hw cylinder from the 1st floor bathroom to the loft,the system is a standard indirect hot water system with cold cistern and expansion tank in loft and boiler on ground floor ,(about a 6ft vertical move)
1.is there a minnimum height needed between cold storage cistern&expansion tank and the hw cylinder,
2.do i have to keep the length of vent pipe(s) from the hw cylinder at the same distance as they are currently(there is space),or is there a calculation i can use for this,the only calcs i have seen,say vent rise s/be 40mm for each 1m by which water level in cistern is above base of BOILER?+150mm,
3.do i need to notify this work?
thanks
