Burning fuels no longer viable, says Mitsubishi

Mitsubishi Electric has unveiled redical plans to convert builders and owners of commercial buildings to the potential for heat pumps for space heating and hot water.

The manufacturer believes that current and planned legislation about renewables, together with improving economics for the technology, make it ideally placed to take over much of the renewable heating territory currently met by biomass boilers.

Divisional commercial director Donald Daw said: “The time has come for heat pumps to step out of the shadows. We believe the burning of fuels to heat commercial buildings is no longer sustainable and we are convinced that heat pumps will be the mass market alternative.

“Renewable energy is the obvious choice for fuel utilisation but people don’t yet truly recognise the heat pump as a heating device.”

The fi rm said that it had made the new VRF-based heat pumps “heating only” to ensure it qualifi es as a renewable technology under UK and EU definitions.
Mr Daw said: “The Renewable Heating Incentive, as it is proposed,does not recognise systems that cool.”

In addition, he said, adding cooling would increase both a building’s energy footprint and
the carbon emissions for SAP calculations.

Mitsubishi believes that its new range of heat pumps offer more ease of use, reliability and fl exibility than biomass boilers for customers looking to meet renewables obligations.

Product marketing manager Philip Ord said: “For air to water heat pumps, installations under 200 kW will be cheaper than a biomass boiler, and will not require the hoppers or access requirements of biomass.”

Each modular unit provides 25kW, with the ability to integrate up to 200kW at a time. The heat pumps are available as air source or ground source systems, and can deliver to the building either via ducting for space heating, or via a boiler unit to radiators, underfloor circuits or to the hot water system.

Domestic water can be supplied up to 70 deg C and water for heating up to 45 deg C.

Mr Daw said that government and planning policy was moving towards recognition of heat pump
technology: “We believe the increasing requirement for renewables means space heating
can only really be met by biomass boilers or heat pumps.

“This is a massive opportunity for the commercial heating industry.”
