My very old Valiant combi boiler needs to be replaced. Nat Grid capped off the supply after I smelt gas and the plumber who came later couldn't get the rusted pump off. It appears to be truly welded to the pipe work inside the boiler.
Anyway, it's a very old gas guzzling open flame pilot light boiler which I'm now going to replace with a new 24/80 condensing boiler installed (possibly a Worcester Bosch or Main).
The problem however is that I live on the 6th floor of an old Victorian building in which all the flats appear to share the same water supply from the mains outside. Therefore, the 1 bar pressure supplied courtesy of Thames Water becomes diluted as the water goes further up the building. The plumber measured only 0.5 bar pressure.
This is not a problem for the central heating, but it is a big problem for the shower, bath and sinks where the hot water trickles out.
The solution appears to be a pump. The question is, will I be able to attach a pump to the fresh water inlet before the water enters the boiler or must I attach the pump to a tank which I don't have and don't want because they take up too much space in my flat which is only 30 square meters (I'm in central London where space is a premium especially in declining market)? Also, I regard tanks as breading grounds for germs and limescale.
I would be grateful for any advice for the above and also any recommendations for type and make of boiler and pump and where I can buy them cheaply (I live in the paddington, w2 area)
