Greetings and Felicitations, O Great Ones!First see earlier threads:Back boiler. Stiff nipple screw?!"We have Lift-off!" Sealed CH System.Looks like we will be taking the plunge so to speak and changing our boilersooner rather than latter.Requirements:3 bedrooms, bathroom, DHW cylinder.Dining room (Double Rad), Parlour/Sitting Room (DoubleRad), Kitchen.Due to some little know kitchen design regulation the kitchen "must have akick-space radiator". There is no appeal against this W.S.Last year I did my heating calculations using u-values and all that goodstuff from Rocky Prescott's site.So I think the Rads are speced correctly.Bed rooms on Zone 2Downstairs zone 1DHW (Own zone0Seperate 3/4" (Yes, we still use Imperial system) flow and return to Kitchenlaid in.bathroom on when any zone on.At the moment we have a Baxi Bermuda 552. (BBU and fire front) in diningroomNow the problem/challenge?!The new boiler and its location.We will probably go condensing. No gas fire in fire place. (I'm Googleingpast threads at mo)All my improvements are beside chimney brest: pump, valves ,programmer etc,in a specially built cupboard.So location for boiler?Have read Ed's faqs and other stuff.Francis

Yep.

You are stuck with two choices.

Tanks, cylinders and pumps.
An accumulator eliminating a cold water storage tank and pumps, but a cylinder is still required in either an unvented cylinder or a thermal store/heat bank.

Gonna run system with cleanser until Saturday and then flush and refill.

I'll post an update next week.
