Key considerations
As part of a larger project to refurbish three building units, the older gas-fired LPG central heating system was replaced with four Aerona3 air source heat pumps. Due to the nature of the retrofitting, various factors had to be considered, including the location of the air source heat pumps, the noise levels, building insulation and size of the radiators.
CEO of Heatforce Paul Maddocks, explained: “In one unit, we installed two Aerona³ 17kW air source heat pumps complete with thirty-one radiators, and in the two other units, we fitted another pair of Grant heat pumps, this time 13kW models, as well as twenty-six radiators – complete with new pipework and new plumbing throughout.”
Both the 13kW and 17kW Aerona³ air source heat pumps, which both have the Quiet Mark, are twin fan units and boast excellent SCOP efficiencies. Both models are also compact in size with a small footprint and have been designed for straightforward installation, easy operation and simple maintenance.
Going greener
The installation of the Grant Aerona³ heat pumps will provide renewable heating to the offices and was part of a drive by the local authority to reduce carbon emissions.
This project showcases how air source heat pumps are helping commercial environments swap from fossil fuel heating systems to greener, more sustainable alternatives. Solar PV was also fitted to help reduce running costs sustainably together with metering for all units to measure costs.
“Our client not only wanted air source heat pumps to keep these refurbished buildings warm but they also wanted to upgrade the buildings themselves so that their energy efficiencies were significantly improved,” said Paul.
“The installation of the Grant heat pumps fulfilled the client’s brief and they are very happy with their new heating systems,” he continued.
“In particular, they are very pleased that they chose a renewable heating system, one that will sustainably meet the heating and hot water demand of the offices while also helping them to minimise their impact on the wider environment.”
