I posted a couple times about fitting a new gas boiler and would like to thank all who responded.
To re-cap I need a new boiler as the WB Heatslave is v/reliable but 20yrs old and probably only about 60-65% efficient.
Until today I was thinking Veissmann Visodent 30Kw, but I had a visit from a heating engineer, he said that over the past 6 months fewer stand alone gas boilers than ever before have been sold and that the market is dwindling in the face of fossil fuel price increases. With today's announcements from the scottish supply group it's clear that prices will probably go up every year by at least 10%. With this in mind the focus needs to be on running costs. I know I can get a new gas boiler installed for £2.5K, but with the RHI scheme about to start in October it seems that incorporating renewable technology into the heat generation of homes may take off in a similar way to solar PV panels. The engineer said that although the capital outlay is a lot more, the system will pay for itself by very low running costs and ongoing government cash incentives.
The system I'm waiting for details on does include a gas combi, but that's linked to a pressurised tank and an exterior heat pump panel. This panel is only around 2000h x 800w x 50mm thick, it can go anywhere outside, even vertical on a wall, it consumes 360W and works down to -21ºC, overnight it will heat the 250L tank for pennies.
I'm waiting for costs to instal and also details of the govt scheme, also got to do the maths to work out the cost projections to see which system will cost less over a 5-10 year period or more.
A more expensive option would be full heat pump with outside heat exchanger, that way no gas to pay for!
Has anyone else got experience of renewable for central heating?
