Mitsubishi Heat Pumps
Don’t waste your energi
Heat pumps are a key part of the UK’s heat decarbonisation strategy, so careful selection is essential to ensure optimal building performance. Although it is possible to design systems where heat pumps are the sole heat source, a hybrid solution where combinations of heat pump, elec- tric boiler, gas boiler, CHP and waste heat input allow the energy centre to be dynamic and react to future carbon and tariff signals. Coupled with well-sized thermal storage, the system can deliver the lowest cost heat while also achieving its carbon reduction objectives.

Key features and benefits
Air-source solutions for heating systems, heat networks and sanitary hot water
Electrified heat source
High efficiency. SCOP typically between 2 and 3
Stable flow temperature, even at low ambient conditions
Modular approach for dynamic loads
Integration with other heat sources to form hybrid energy centres
Heat pumps in a hybrid energy centre
In a hybrid energy centre, heat pumps are sized to provide the maximum share of energy (kWh) but are not sized to the peak building load (kW) as this is extremely expensive and results in over-sized, under utilised appliances. Hence, cost effective peak capacity should be provided by boilers.
Heat pumps use a vapour refrigeration cycle to generate hot water
by harvesting energy from a lower temperature source. This source is generally air or water, and could be from the ambient air, exhaust air, river water, bore hole, mine water and many others. The input energy is electricity to power compressors and fans if the source is air. Efficiency is the ratio of heat output divided by electricity input, known as COP (Coefficient of Performance).
