Solar water heating systems = Solar panels + solar energy. Solar thermal: solar power & solar hot water. RHI solar.

Solartwin review of how to save the planet – with what we think are the best solar panels.

Five ways to help to save the planet with Solartwin.

1 – Green telephone solar surveys. Do you really want to have loads of salespeople driving and emiitting exhaust fumes and CO2 on the way to your home in order to quote you for a solar heating system? What’s the point? So it makes environmental good sense to get solar water heating quotes by phone, backed up with aerial photos of your roof and to have an address of a local Solartwin user (not a show home!) for you to visit.

2 – The best coefficient of operational energy and carbon performance. Conventional clunky old solar is badly designed because it still has to run on mains electricity. DTI research reported as long ago as 2001 that people installling old types of solar water heating to save mains gas paid an 8% energy penalty and a 20% carbon penalty for doing so. Solartwin has no mains power consumption. So it has no energy or carbon clawback. So it makes environmental good sense to choose a zero carbon solar water heating system.

3 – Great carbon dioxide savings. One Solartwin installation saves around 250 kg of CO2 per year if you are displacing mains gas as a fuel. Your CO2 savings can be even higher still if you save fuels which have higher carbon impacts than mains gas, such as bottled gas, (LPG / Butane, Propane) oil or coal. Installed across the world for over a decade, to date, several thousand Solartwin installations have saved over 4000 tonnes of CO2 emissions from taking place!

4 – Less kit means less waste. Most solar water heating systems need new hot water cylinders. Solatwin often does not. It can often fit direct onto an existing cylinder, if it is on good condition. Besides saving money (and complying with HSE guidance on Legionella) this approach also saves the environment, because less waste and less manufacture is taking place. So it makes environmental good sense to specify retrofit solar heating where you can.

5 – Light footprint life cycle analysis. Solar water heating pays back the energy invested in its manufacture in just two years. Then you are straight into energy and carbon credit. That’s the point. Why wait twice as long with conventional solar thermal systems? This Life Cycle Analysis figure comes from Bath University. Do you want to buy energy intensive clobber? Or a well designed, low environmental impact technology such as Solartwin? Conventional mains pumped solar takes over twice as long (4.5 years) to reach energy breakeven.

Every time, it makes environmental good sense to specify Solartwin.

Step lightly! Select the green solar option. The Solartwin review of solar water heating systems concludes that the bottom line is always the environment.
