Lochinvar extends Renewables offer with Air Source Heat Pumps

Leading boiler and water heater manufacturer Lochinvar has extended its range of LZC solutions, with the introduction of an air source heat pump range as part of its renewable packages.

Six air source heat pumps are available with outputs ranging from 4kW to 16kW. The heat pump unit is sited externally and ambient air is used to supply pre-heated feed water for the selected Lochinvar high efficiency gas-fired water heater, providing reductions in fuel consumption, saving both money and carbon emissions.

Air source heat pumps are fully weatherproofed units and easy to install. No refrigeration pipework is required, just a hot water circuit connection and a single phase power supply. The user interface controller ensures easy management of the system, offering clear and simple instructions.

Heat pump efficiency is often referred to as Co-efficient of Performance (COP) with up to 4:1 being available on air source models. This means the unit will generate up to 4kW of output for every 1kW input. Although water temperatures of up to 55°C are achievable, COP is usually at its best when providing water temperatures of around 35°C. Integrating air source heat pumps with direct gas-fired condensing water heaters offers an efficient and environmentally friendly method of providing hot water for a wide range of commercial buildings.

David Pepper, managing director for Lochinvar, said: “With the continuing drive towards improved hot water system efficiencies, we believe these packages provide a solution which utilises a renewable technology at a reasonable level of capital cost. In addition to our now established solar/direct gas-fired water heater packages we are pleased to provide further flexibility for commercial users who wish to reduce carbon emissions without compromising the hot water supply.”

Lochinvar is one of the UK’s leading suppliers of high efficiency boilers and water heaters for commercial and industrial applications. The company offers an extensive product range, including the EcoKnight, TurboCharger and EcoForce condensing water heaters, which all have potential to be incorporated with renewable systems.
