Afterwards all RHI goes to the property owner. Any losses would be borne by the initial lender who would be permitted to borrow at a fixed rate at the current BoE base rate. <br /><br />Never going to happen unfortunately.

You would use it to need space. You would not use a ground source or air source heat pump for hot water heating. The COP would be too low. <br /><br />It's not either/or, but both and for solar PV and solar water heating. However if you have a limited budget and a choice, solar water heating presents better value for money because it's cheaper to install assuming you already have an immersion tank.DavidKThorpehttps://www.blogger.com/profile/04215770376688861114noreply@blogger.comtag:blogger.com,1999:blog-18727745.post-67558430729430059732012-10-05T22:27:03.424+01:002012-10-05T22:27:03.424+01:002y 12/03/2010 comments were spot on eh?

You should see what I'm predicting these days - it's shiny. <br /><br />I read your REA article today talking about renewable heat and how we should support it. I disagree with your point. With PV you make electricity which is a high quality energy source. You can power a heat pump with a COP of 2.5+ which allows you to generate heat more cheaply that direct solar heat. Cheaper cheaper is good but the fact that you're storing a product (hot water, hot air) is also very good because you're provided an easy way to manage your on-site power production.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18727745.post-6654397127638458652012-07-19T17:49:22.635+01:002012-07-19T17:49:22.635+01:00It's an interesting point and as often with st...It's an interesting point and as often with statistics depending on how you interpret the results can give two wildly different opinions.<br /><br />When comparing the emissions from electric and ICE cars do you know if they include all the energy used in the process of getting the fuel into the car? i.e. energy used to get the oil out of the ground, massive amounts of energy to refine it, shipping it halfway around the world in a tanker before delivering it to the petrol station?<br /><br />The same of course can apply for electricity but is again dependent on what the file type is.

You go on to opine: <br /><br />"It has obviously escaped Mr Hanson's notice that ALL fossil fuels have been created by carbon sequestration so burning them would be carbon-neutral and restore the earth's atmosphere to the status quo ante. Hence all his arguments about the natural state are nonsense."<br /><br />a) it may have escaped your attention, but the fossil fuels have formed over a timespan of a few hundred million years; b) returning all that stuff to the atmosphere over a few hundred is therefore carbon neutral in the most extreme sense that can be imagined, c) the last time a large carbon-spike of the type you apparently favour occurred it was accompanied by a mass-extinction and d) whilst a Hothouse climate may be more representative of the Phanerozoic, a geologically-orderly transition to it is desirable whereas a rapid one of several centuries is not.<br /><br />Hope that helps.John Masonhttps://www.blogger.com/profile/10349118555646220221noreply@blogger.comtag:blogger.com,1999:blog-18727745.post-34219655397629252042012-05-09T16:22:04.047+01:002012-05-09T16:22:04.047+01:00Oh dear
