Heat Pump & Solar PV Installation in Flushing, Cornwall

Mitsubishi Ecodan heat pump cylinder installed alongside a GivEnergy battery system in Cornwall home

Project Overview

GreenGenUK recently helped a homeowner in Flushing, Cornwall, transition away from oil heating and towards a cleaner, more sustainable energy solution. By combining an air source heat pump with a solar PV and battery storage system, the customer can now enjoy lower energy bills, improved efficiency, and a significantly reduced carbon footprint.

The Heating Upgrade – From Oil to Air Source

The old oil boiler was replaced with a highly efficient Mitsubishi Ecodan R290 6kW air source heat pump, paired with a 250-litre Telford Tempest unvented cylinder. To maximise efficiency and comfort, we also installed eight upgraded radiators sized to suit the property’s heat loss requirements.

  • 100% of space heating and hot water demand now met by renewable energy
  • Projected annual running cost of just £759, based on full heat loss design
  • Eligible for the £7,500 Boiler Upgrade Scheme voucher, reducing upfront cost significantly

The Solar & Battery System

To complement the heat pump, we designed and installed a 3.72kWp solar PV array with integrated battery storage.

  • 8 x Aiko Neostar 465W all-black solar panels
  • Renusol mounting system for a sleek roof finish
  • 1 x GivEnergy 3.6kW hybrid inverter
  • 1 x GivEnergy 9.5kWh battery for energy storage

Performance highlights:

CO₂ savings of over 900kg per year, equivalent to planting 174 trees over the system’s lifetime

Generates around 3,561 kWh per year

Expected 60% energy independence with battery storage

Projected £32,185 lifetime bill savings with a 9-year payback period

Customer Feedback

“GreenGen have just installed solar panels, a battery and a heat pump for me, and I am very pleased with the outcome. I was extremely impressed with the guys who did the installations – they were very professional, working to extremely high standards, and very pleasant to have around the house.

Ben E, who did the heat pump installation, was creative in thinking around various issues that arose, including advising a much better location for my pump, and made all the pipework and trunking look absolutely immaculate. Max handled the installation of the battery and the inverter with similar precision and professionalism. The guys who installed the solar panels were also great. I was also impressed with Josh in the sales team who was patience personified with my endless questions and requests for more information at the start of the process.”
