Solar hot water systems are the best solution for homes wanting a green heating technology to reduce carbon emissions, according to Ethical Consumer magazine.
In the magazine’s latest Buyers’ Guide, the publication compared biomass boilers, ground source heat pumps and solar hot water heating.
The magazine found that while biomass boilers can provide the largest carbon savings, they are also among the most expensive renewable heat technologies, costing around £11,000. The Buyers’ Guide also questions the long-term sustainability of biomass feedstock.
Biomass boilers can also end up costing £40 a year more to run than a typical condensing gas boiler.
By comparison, solar hot water systems are the cheapest renewable technology to install at around £4800 for a typical system, saving a modest amount of carbon and up to £60 a year on energy bills against a typical condensing gas boiler.
“As the cheapest and easiest technology to install, if households are looking to buy a renewable-heating system in our view the best option would be to choose a solar hot water system,” says editor Rob Harrison.

Green Sense for the Home: Rating the Real Payoff from 50 Green Home Projects | $20.07 | BetterWorld.com - New, Used, Rare Books & Textbooks | In this information-packed book, they walk readers through 50 green home projects and break them down according to the positive impact they have on the environment, as well as the impact they may have (both positive and negative) on the reader's wallet. This unique perspective on going green is a reference that green-leaning homeowners simply cannot do without. The authors of this book provide the answer to this and other questions relating to the cost (and relative value) of environmentally friendly home improvements. They evaluate a wide array of projects, including insulating pipes, weatherizing doors and windows, composting and recycling trash, installing a solar hot water heater, installing green countertops, upgrading appliances, building with reclaimed materials, and installing radiant heat. Eric Corey Freed and Kevin Daum are experts, respectively, in green building and in financing custom homes. |

Heating: Geothermal Heat Pump, Renewable Heat, Geothermal Heating, Biomass Briquettes, Electric Heating, Air Source Heat Pumps, | $25.70 | BetterWorld.com - New, Used, Rare Books & Textbooks | More: http://booksllc.net/?id=709696 7 Excerpt: A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that pumps heat to or from the ground. The engineering and scientific communities prefer the terms "geoexchange" or "ground source heat pumps" because geothermal power traditionally refers to heat originating from deep in the Earth's mantle. It uses the earth as a heat source (in the winter) or a heat sink (in the summer). Geothermal heat pumps are also known by a variety of other names, including geoexchange, earth-coupled, earth energy or water-source heat pumps. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency. ...

Ground source heat pumps harvest a combination of geothermal power and heat from the sun when heating, but work against these heat sources when used for air conditioning. Like a refrigerator or air conditioner, these systems use a heat pump to force the transfer of heat. Heat pumps can transfer heat from a cool space to a warm space, against the natural direction of flow, or they can enhance the natural flow of heat from a warm area to a cool one. |
