I need some advice please.
I have had several quotes for a central heating and hot water installation for a large 3 storey house with 22 rads (inc towel rails) but the advice I am receiving is conflicting and just wanted a bit of insight please.
Chap number 1 suggests 22mm flow and return in the middle of the house (hallway) with the flow branching off to each floor from the single initial flow pipe at each floor. Then 15mm to radiators - some of the radiators are quite far away from the middle of the house so would mean the 15mm runs are quite long.
Chap number 2 suggest as number 1 but with 28mm.
Chap number 3 suggests as number 2 (28mm) but with the flow separating out of the boiler as early as possible and then separate 28mm to each floor.
Aside from the extra cost of options 2 and in particular option 3, are there any advantages/disadvantages?
