Hi,
I have an old central heating system which needs changes and improvements and so I would be grateful for some expert advice please. At present I have a Homeglow fire/back boiler combination system which feeds an old rectangular indirect tank in the bathroom. There is only one pump for the three radiators which it also feeds and the hot water tank appears to heat from conduction only. With the combined header tank in the bathroom, at two feet above the sink and bath taps, means that ground floor user's gets priority for hot water.
My ideal is to eventually do away with the fire/back boiler combination and to put a condensing boiler outside in the lean-to section of the house. An on-demand system seems ideal but advice, or pointers to information, on this would be appreciated. I'm not sure of the benefits between different systems at present to make any kind of informed judgement.
Right now I have to move the existing tank into the loft so that I can update the bathroom and so I need to install something which will fit in with my future plans of moving the heating source to the outside location.
Ideally I'd like to do something at this point in time which didn't involve having to have two water tanks in the loft as I've seen heating cylinders which look to be completely self contained and highly efficient.
By sighting a new hot water cylinder directly above where the present one is then I can simply extend the existing piping up into the loft and through adding pumps and valves I can make things much more efficient and suitable for the house. Basically I need a two stage plan that will allow me to expand and improve the existing system but which will hopefully contribute components to an eventual ideal system.
All comments and advice grateful received and thanks in advance Kind regards and best wishes Phillip
