Did you know that in northern countries like the UK, the earth just a few feet below the surface keeps a constant temperature of between 11 and 12 degrees Centigrade, even in winter? It traps the heat of the sun, and stores it underground, all year round. A Ground Source Heat Pump transfers this heat to your home to provide space-heating. Using a compressor (a bit like the one in your fridge), it increases this heat to around 45 or 50 degrees, and transfers it to radiators or underfloor heating. The heat can also be used to pre-heat your hot water, meaning you need less gas or electricity for this also.
Because they make use of the renewable energy stored in the ground, Ground Source Heat Pumps provide one of the most energy-efficient ways of heating buildings. The only energy used by Ground Source Heat Pump systems is the electricity to power the pump. Normally a system will deliver 3 or 4 times as much thermal energy (or heat) as the electrical energy used to drive the system. If you can source your electricity from a renewable source such as wind or solar, then your heating will be completely clean and non-polluting.
Ground Source Heat Pumps have been widely used for many years in both Europe and North America. There are now several hundred thousand in operation. In Germany, tens of thousands of systems are installed each year. They typically cost more to install than conventional heating systems. In the UK you should currently expect to pay around £8,000 (plus VAT) or more to heat a medium-sized house, although government grants can refund some of this cost (up to £1,200 is available in England and £4,000 in Scotland). However, Heat Pumps have very low maintenance costs, and can be expected to provide reliable and environmentally-friendly heating for over 20 years.
In a modern, well insulated house, a Ground Source Heat Pump system can also save you money on running costs. It is likely to be cheaper to run than an oil-fired boiler, and less than a third of the running cost of electric heating. Currently it is likely to be just a little bit cheaper than the very best of the modern condensing gas boilers, but gas prices may well rise in the future in many countries.
There are 3 main elements to a Ground Source Heat Pump system. The first is the âground loopâ which is a length of pipe buried in the ground, either in a borehole or a horizontal trench. For a modern detached house you will typically need two trenches about 40 to 50 metres long to supply enough heat for the house. The ground loop collects the heat from the earth. The second main element is the heat pump, which is typically the same size as a fridge-freezer. This transfers and increases the heat from the ground loop. Finally you need a distribution system which basically means underfloor heating or radiators.
Ground Source Heat Pumps are most suitable for homes that are well insulated, because otherwise they can become very expensive to install. The cost of a system is directly related to its size, which is in turn driven by the heat it needs to deliver. If you live in an older building with very high heat loss, this can add substantially to the capital cost on installing a heat pump. Money spent on upgrading wall, floor and loft insulation can save a large amount on this capital cost. Unfortunately, some older buildings can never be made sufficiently energy efficient to use the modern heating distribution systems that go with Ground Source Heat Pumps, such as low temperature underfloor heating, or low temperature radiators.
You should consult a professional installer if you are considering such a system. They will be able to give you detailed advice on the suitability of your home. Issues that you should consider are things like whether you have enough space to dig the trench for the ground loop, what kind of heating distribution system you want (e.g. underfloor heating), and the size of Heat Pump you will need.
With over 40% of carbon dioxide emissions coming from the heating of buildings in countries like the UK, energy-efficient systems like a Ground Source Heat Pump are looking more and more attractive. If your home is well insulated, and you have some outside space like a garden, it really is worth investigating a system like this to help cut your personal contribution to Climate Change, by making better use of the free heat supplied by the earth.

In a very hot temperature like summer, the mattress is shielded by the heating mattress pad. We easily keep away such heating mattress pad which is fixed to the mattress on the beds. Therefore, it is very easy to dry-clean and wash out such heated mattress pad. The material that is used in the heating mattress pad is of several qualities. It ranges from polyester to cotton. Various kind of fabric material like cotton, wool, feathers are used to make two types of coating on the heating mattress pad and these coatings are tightly sewed up together. Therefore, such type of manufacturing provides the softness and comfort to the heating pad.Â
One of the technical objectives of the manufacturing of the heated mattress pad is to generate the heat according to the room temperature directly to the body instead of growing into the air. So that makes your body temperature maintain with respect to the coldness, warmness in surrounding temperature. So indirectly, the heating mattress pad assists us to minimize and save our electricity bills.
If we compare the heating mattress pad with electric blanket, then the warmness in the heating mattress pad is much more than it.

Assuming the gas central radiator is connected to the same current gas central heating system we already have.
You can go to this website and compare your costs for both electricity and natural gas. Have the price per kwh and price for gas available, and do a comparison there in terms of BTUs versus cost.
Good Luck!

It would be nice to go green but it needs to make sense money wise. We have a 1,300 square foot home on the beach home with plenty of sun. Our electric bill is 100 bucks a month give or take. How much will solar panels cost and how many solar panels will we need to effectively power our home.
You could easily knock 40 percent or more from your power bill by using a manual on off switch on your electric hot water heater and check efficiency of any electric refrigerator and or freezers.
Like you say, your place is on the water, wind power would be the best way to go because of onshore winds which would get you up and running for much less than solar and likely be good 24 / 7 rather than daylight only.
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills. Get it from here: http://www.earth4energy-review.com
Hope everyone will follow this guide and save the earth.
I have seen so many of these, and while they do sound good, it basically come down to a sales pitch without any concrete information other than to pitch their E-book, which doesn't even involve printing cost.
The testimonials are alway just names without contact numbers, even the ones that say they would be happy to recommend it.
The big question is, is this your book?
and if it is not your book, have you tried it?
Can a Dehumidifier cut your electric bill?
What it does is to make warmer temperatures feel better. If, for example, you normally set your AC at 75, you may be able to set it at 80 while running the dehumidifier. This would save energy. Hope this helps.
