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.
“The launch of the Renewable Heat Incentive means that there's never been a better time for homeowners to think about installing renewable-heat technologies,” he adds. “Over time this initiative will in effect pay for whatever system you choose.”
