Making the transition

We all become comfortable in the familiar. But invariably, it’s not always the best place to be.

In a flagship Cornish example, GreenGenUK helped a homeowner in Flushing make the leap from traditional oil heating to a fully renewable, future-proof energy system. The old oil boiler was replaced with a 6 kW Mitsubishi Ecodan R290 air-source heat pump, supported by a 250-litre unvented cylinder and newly-sized radiators to suit the property’s specific heat-loss profile. As a result, 100% of the home’s space heating and hot water demand is now met through renewable energy, with the projected annual cost of running the system estimated at just £759.

To maximise efficiency and resilience, GreenGenUK also fitted a 3.72 kWp solar photovoltaic array (8 high-performance Aiko Neostar panels) combined with a 9.5 kWh battery and hybrid inverter. This setup is expected to generate roughly 3,561 kWh of clean electricity per year, deliver 60% energy independence, and save more than £32,000 over its lifetime, paying back in about nine years. On top of that, the system reduces CO² emissions by over 900kg annually, which GreenGenUK equates to planting 174 trees over its lifespan.

The homeowner was effusive in their praise: the installation team was described as “very professional and creative in thinking around various issues” and leaving “all the pipework and trunking … absolutely immaculate.” It’s a very tangible demonstration of how Cornwall residents can cut costs, reduce their carbon footprint and futureproof their homes, all with GreenGenUK’s trusted, local expertise.
