With the cost of heating fluctuating month by month, we are finding most users don’t actually know the cost of running their heating system.

Using industry information we have compiled an example cost of heating comparison guide for the main types of heating system. As every heating system is different we can input specific details from your own home or business to compare your current usage against a renewable alternative. This can help you make a decision on what technology is right for you. Download the Cost Comparison Guide here.

GreenGenUK offer a complete design and installation service of renewable energy systems through the south west using our own in house installation teams and project managers. Being MCS accreditation means that all of our systems are eligible for Government Backed incentives such as Feed in Tariff (FiT) and the forthcoming Renewable Heat Incentive (RHI).

While most have heard of the Feed in tariff, the Domestic RHI is still relatively unheard of by homeowners. The RHI is the world’s first financial incentive of its kind to revolutionize the way heat is generated and used in buildings.

The Renewable Heat Incentive (RHI) will support emerging technologies and businesses in the UK, strengthening security of supply by reducing dependence on fossil fuel heating and emissions.

  • Currently around half of the UK’s carbon emissions come from the energy used to produce heat – more than from generating electricity. The RHI will reduce emissions by 44 million tonnes of carbon to 2020, equivalent to the annual carbon emitted by 20 typical new gas power stations.
  • Over 95% of heat in the UK is currently produced by burning fossil fuel but with North Sea supplies now in decline leading to an increase in imports, low carbon alternatives are needed.
  • The new financial incentive will encourage installation of equipment like renewable heat pumps, biomass boilers and solar thermal panels to reduce emissions and support the existing 150,000 jobs in the heating industry.
