New builds, Cornwall


A small development of new build properties has been completed near Helston in Cornwall, homes which will be exclusively available to local people with long-standing associations with the area. The homes have renewable heating systems installed with Aerona³ air source heat pumps and cylinders all supplied by Grant UK. 

New build


Air Source Heat Pump (6kW)


For over twelve months, a development of two three-bedroom houses and four two-bedroom flats has been built in Ruan Minor near Helston, Cornwall. The new build properties were granted permission based on the homes being made available to people who are local or who have strong connections to the parish area. The ethos of the build was to create homes for the local community, homes that would be both affordable and sustainable so to ensure that all the stipulations laid out in the planning permission were fulfilled, renewable heating systems were required.


The developer appointed Jonathan Bray of D & J Bray Plumbing and Heating Limited, local G1 Installers, to design and install the heating systems at all six properties. Working closely with Grant UK’s in-house Design Team, Jonathan carried out the heat loss calculations, completed the system design and specified the package of products needed to meet the heating and hot water demand of the homes. For each property, an Aerona³ 6kW air source heat pump and a Grant High Performance 200ltr Pre-Plumbed cylinder with integrated buffer was specified and installed, to work alongside standard compact steel radiators.

The Aerona³ 6kW heat pump is the smallest unit in the range, combining a small footprint with an A+++ ErP rating. Its reliable performance alongside its compact design made it the ideal solution for both the houses and flats on this development. 

“We always knew we were going to install Grant for this project,” comments Jonathan Bray. “We have worked with Grant UK for many years, installing their oil boilers and now we are actively involved in the renewables sector too. This project was very different to our usual work and working with housing associations and tenants was a different experience compared to supplying a private buyer. However, Grant UK were on hand at all times, from design through to the commissioning, so the project ran smoothly from start to finish.”
