I am building an extension, and am replacing boiler and tank. The choices appear to be:
gravity fed "traditional"
"combi" of some sort
mains pressure system (vented or unvented)
The boiler will feed some radiators and an underfloor heating system. There will be three toilets, 4 sinks, and either 2 baths with showers over, or 1 bath with shower over and an additional shower. I want a really good shower pressure and flow, and don't want to wait forever to run a bath. It has been suggested the water main into the house is replaced, and that can be done if it helps. Due to lack of space one advantage of a mains pressure system was seen as mounting the tank in the loft space. It is intended the boiler will go in the loft space against one of the eaves.
Any thoughts?
