I'm hoping for some help from anyone that's gone through the same process as I'm about to start. I'm looking to convert our loft and currently have a fully functional regular heating system with f&e tank, cold water tank and Worcester Bosch boiler that looks under ten years old all in the loft and a hot water cyclinder in airing cupbaord on the 1st floor. I have had British Gas out to quote and they have said that the property is unsuitable for a combi as they were getting 2 bar of pressure but a flow rate of 11 litres per minute. I have the water company coming out as there is water pooling in the hole where the stopcock was changed about 6 months ago.
It's currently a 4 bed detached house with one main bathroom and one en suite. The loft will be master bedroom with en suite and I think I am leaning towards and electric shower for redundancy purposes. If a combi boilder is out of the question, should I just replace the cold water tank with coffin-style tanks and locate them under the eaves to be boxes in and replace the f & e tank with an expansion vessel? Can I replace the hot water cylinder with an unvented cylinder, keep the regular boiler and replace it with a system boiler when it packs up?
