Calorex heat pumps are charged with non-toxic, bio-degradable, CFC-free refrigerant, which has no detrimental impact on the earth’s protective ozone layer.
Calorex heat pumps - designed and manufactured in the UK Calorex has been manufacturing heat pumps in the UK for over 30 years and has unrivalled experience and expertise in heat pump technology. More domestic installations have been supplied by Calorex than by any other manufacturer. Our range of ground and air source heat pumps has been developed specifically for UK housing, climate conditions and heating system designs. As well as efficiently heating your home, Calorex heat pumps are uniquely designed to supply domestic hot water at 65°C, without the need for electric heating back up. Heating and hot water are managed by a standard central heating programmer with a room thermostat controlling the heat output in exactly the same way as with a conventional boiler. Legislation and funding support Most planning application approvals now require houses to be built to code levels 3 or 4 of the new Code for Sustainable Homes. This enforces substantial improvements in energy efficiency over and above Building Regulations Part L. Field trials show
that code level 3 can be achieved with a Calorex air source heat pump and level 4 with a Calorex ground source heat pump with no change to the basic structure of the building. The installation of ground source heat pumps can qualify for funding support of up to 80% under the Carbon Emissions Reduction Target (CERT) and Low Carbon Building Programme (LCBP) schemes. The Calorex sales office can arrange for funding support quotes with E.ON who is a nominated supplier under these schemes. Calorex air source heat pumps now also qualify as a renewable energy source under European legislation. Private householders can apply for funding.
Product features • Accredited under the Government’s Microgeneration Certification Scheme (MCS) • Dual temperature operation for maximum heating efficiency • DHW up to 65°C with no immersion heater or direct electrical resistance heater required • Space heating temperatures variable from 35°C to 55°C for underfloor heating or radiators • Twin compressors in larger models to optimise efficiency • Plumbing and electrical connections only • Only a single phase electricity supply required • No gas supplies, flues or ventilation required • Maintenance free – no expensive annual servicing required
