Hey all,
Time to access your boundless wisdom again!
We're considering options for replacing our current ch/dhw system. We currently have a gas-fired boiler and tank with a pathetic (7.5kW) electric shower. The tank is shoe-horned into a small cupboard at floor level in the loft-conversion, at pretty much the same height as the bathroom, with the header tank in what's left of the loft - maybe
2m higher. We seem to have the worst of all worlds: a *truly* pathetic shower, a bath that takes 15 minutes to fill, a not-desperately-efficient boiler and wasted energy from the hot-water tank (which isn't well insulated).I've had a bit of a look, using this site and the FAQs, at the alternatives, and it seems to me that what we want is a combi. I need to test the mains flow rate (seems pretty good, though), but as we only have a single bathroom and there is not going to be any need to run baths concurrently with showering (plus, we aren't that fussed about slow bath-running) it seems a heatbank arrangement is overkill. There are only two of us with no plans for expansion at the moment. What are your thoughts?
One of our greatest concerns is the efficiency of the new arrangement
- ignoring, for the moment, the environmental impact of chucking out all the old stuff and replacing it. With the inefficiency of our current system, I guess we'll start saving pretty quickly...
I've checked the SEBDUK database and got the list of 50 most efficient boilers - we'll probably select the most suitable from that list. Can anyone give any extra insight into particularly suitable models?
Thanks again in advance for you help!
Adam...
