Pump up returns on low carbon heating
Installing ground and water source heat pumps has become more financially attractive for organisations of all types, thanks to the government's commitment to incentivise sustainable low carbon heating technology under the Renewable Heat Incentive (RHI) scheme.
The RHI, which is scheduled to be introduced later this year, guarantees subsidy payments over 20 years that will reduce the payback period for organisations that install ground source heat pump and water source heat pump technology.
According to ENER-G, a 200kW ground source heat pump operating 8 hours a day – typical for a school or moderately sized business premises – will qualify for payments of 3 pence for every kWh of useful heat generated, creating a payment of approximately £210,000 over the 20 year duration of the tariff (based upon 350,000 kW hours of heat produced per annum).
The scheme will provide payments on heat pumps installed since 15 July 2009 and aims to support a range of heating systems at all levels, from small businesses and offices, and public sector buildings right up to large factories.
The RHI will give annual subsidy payments for the production of sustainable heating at a level designed to remove the barriers to installation. The RHI tariff for ground and water source heat pump technology is:
Technology scale Tariffs (pence/kWh) Tariff lifetime (years)
Ground source heat pumps (small)
Less than 100 kWth 4.3 20
Ground and water source heat pumps
(large) 100kWth and above 3 20
"The RHI demonstrates the government's commitment to renewable technologies and is yet another benefit for clients utilising heat pumps as part of their low carbon strategy", said Paul Burley, managing director of ENER-G Sustainable Technologies. "Ground source heat pumps are the first choice for many clients as the technology scores extremely high against other renewable technologies, where carbon reduction is paramount."
He continued: "Our in-house expertise and resources means we can see the whole project through from initial feasibility through to handover. We operate our own drilling rigs and offer complete in-house services from specialist design, through to complete project management, installation and maintenance of heat pump technologies. We also have the ability to supply bespoke manufactured heat pumps in a variety of sizes to accommodate complex customer briefs, particularly where space is restricted."
Through its partnership with four leading manufacturers, ENER-G provides one of the widest selections of ground source, gas absorption, air source and water loop heat pump technologies in the UK, supplying all types of applications from 1kW to 1000kW capacity.
Heat pumps supply more energy than they consume by using a refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating buildings or providing hot water. The process can operate in a reverse cycle to provide cooling for buildings as well. Heat pumps can provide a 50% reduction in carbon dioxide emissions compared to traditional technologies.
When combined heat and power is used to drive heat pumps, further energy savings and carbon dioxide reductions can be achieved. ENER-G is using these two technologies in tandem to power the new Malvern Community Hospital, which is one of the greenest hospitals in the UK.
ENER-G Sustainable Technologies has won official certification for its expertise in renewable heat pump technology. The approved contractor certificate recognises the quality of ENER-G's design, supply, and installation heat pumps, in line with exacting technical standards set out by the Microgeneration Certification Scheme. The company is also a member of the UK Ground Source Heat Pump Association.
