Doesn't a heating load make the most sense for a turbine?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34576#Comment_34576 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34576#Comment_34576 Sun, 05 Oct 2008 23:28:25 +0100 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34585#Comment_34585 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34585#Comment_34585 Mon, 06 Oct 2008 10:07:02 +0100 ted
Possibly more sensible to put the power into an immersion heater in a thermal store and then release the heat when needed.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34604#Comment_34604 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34604#Comment_34604 Mon, 06 Oct 2008 13:07:25 +0100 Mike (Up North) Cheers, Mike up North]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34668#Comment_34668 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34668#Comment_34668 Mon, 06 Oct 2008 22:12:49 +0100 richardtheboffin
Is using a water tank thermal store and hot water underfloor heating worth the extra complexity and hence money?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34669#Comment_34669 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=34669#Comment_34669 Mon, 06 Oct 2008 22:23:21 +0100 skywalker
Probably not worth it unless you could do with upgrading and integrating some other your other wet systems.

We could only justify the hole the heat store put in our budget because we needed to completely re-plumb and we really, really, really wanted solar.

If you did, there's a Cornish company that make a heat pump kit that can be DIY installed. They won an award for it this year: http://www.ashdenawards.org/winners/kensa08]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=36207#Comment_36207 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=36207#Comment_36207 Thu, 23 Oct 2008 10:51:03 +0100 howdytom https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=36242#Comment_36242 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=36242#Comment_36242 Thu, 23 Oct 2008 18:00:21 +0100 sjohnson2
"I am director of a small partnership who have spent the past 15 years inventing and perfecting a revolutionary new wind turbine design. We are looking for a Business Angel investor to help us get this project off the ground.

Our turbine aims to be the cheapest dollar per kilowatt turbine in the world and is ideally suited for domestic and urban installation unlike current turbine designs. It runs silent, is incredibly cheap to manufacture and looks fantastic too. We intend marketing two versions, a 300W one intended for powering household lights/refrigerators/ TV/DVDs etc and a larger 1.5KW turbine to be installed in arrays to power farms and rural areas not able to connect to the electricity grid.

The turbine will be bought in a small-suitcase size carry pack and can be attached to a house roof or wall much like a satellite dish. It does not need to be elevated as current horizontal (or propeller type) turbines do. Each 300W turbine will cost around $350 to manufacture including toroidal design PMG and "black box" containing charge/load/shunt controllers, a 600W inverter and deep cycle battery. Cost Price of entire package will be around $700 making it the cheapest dollar per kilowatt turbine in the world.

Our unique turbine control mechanism is patentable but we currently lack the funds to proceed with this. We estimate we need around $250 000 to begin manufacturing and marketing this fantastic turbine which is going to turn the renewable energy market on its head! We have 4000sqm factory space at our disposal and a small manufacturing staff of around 5. For a cash investment and hopefully business and marketing advice and assistance, we are offering up to 30% equity in our company. Please contact me if there are any Business Angels interested in this potentially highly profitable venture.

Our comprehensive business plan which conservatively estimates profits of around $1 750 000 per annum can be supplied on request.

Kind regards

If you hope to benefit from ROC's or Feed In Tarrif, then you will need to have a system where the electricity is measurable at nominal voltage and frequency. For the UK, thats either 230 or 400V and 50 Hz. Voltage has a +/-10% tolerance, but frequency is much tighter. Fall outwith that bands and OFGEM will not accredit your meter, and you will be ineligible for ROC's or Feed In Tarrif. The direct heating system will still work, but you will get no ROC or FIT support for it.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=66609#Comment_66609 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2668&Focus=66609#Comment_66609 Tue, 17 Nov 2009 17:36:12 +0000 SteamyTea
We had a similar discussion a while back but using PV to run a heat pump.

Still I am with you in your thinking. If you have enough thermal storage then it is an effective way of doing it, and as you say, cheap and simple. I am of the opinion that not enough consideration is taken for space heating, tends to be all about heating water or self generating electricity. Though not losing heat is the paramount think so insulate, then insulate some more and then add a bit.
