Martin and his wife had been considering an upgrade of his existing oil heating system for some time and was keen to move away from the use of fossil fuels. Having heard about the benefits of switching to a significantly more cost-effective system, he was keen to explore how an Air Source
Heat Pump could work in his own property, removing his dependency on oil. This is a decision that many people have started making in recent years as the planet turns to more environmentally friendly options.
Shane visited Martin’s home and carried out MCS heat loss calculations, which concluded that a 6kW EcoDan Mitsubish air source heat pump, 250ltr hot water cylinder, and four replacement radiators were the best way forward.
Our team removed the existing oil system and carried out the new heating installation over a period of days, ensuring that the household was left with hot water each evening to minimise any inconvenience to their day-to-day living. We installed the cylinder and accessories in the main house
but the rest of the installation was slightly different for us – we love a challenge! Martin’s heat pump was fitted at the top of the external wall, well above head height. We don’t tend to do this as standard, but on this occasion, it was the only logical place for it to go. A scissor lift was used to get it
in place, and the heat pump was fitted to a bracket to keep it securely in place. Our work is all about finding solutions, and in this case, it was about looking outside the box. The end result was perfect.
As part of the system replacement, we also added in-roof solar photovoltaic for electricity, with two Huawei 5kW batteries. This gives a seamless finish and contributes towards the running costs of the heat pump. A heat pump and solar system combo make the perfect installation when fitted
together.
Martin was delighted to take advantage of the Government’s Boiler Upgrade Scheme (BUS) and received £5,000 towards his installation [the BUS scheme has now increased their grant to £7,500]. He is extremely pleased with his new heating system and is already reaping the financial rewards.
Testimonial:
Eco Installer designed and installed an air source heat pump, solar PV and battery storage system for us to replace our oil-fired central heating. We were really pleased with all aspects of the work, from the initial survey and design to the quality of the recommended components and the quality of the installation. The project management to coordinate the deliveries and different trades required at each stage was excellent.
The installation of the air source heat pump involved some new radiators and a move of the water cylinder. The installers did a great job here, ensuring we were left with hot water at the end of each day and leaving us in a very tidy state for what was a relatively significant amount of work. There was a delay in the supply of solar panels (out of Eco Installers; control due to supply chain issues), but we were kept informed throughout.
We’re really pleased with the experience of the air source heat pump – the model fitted is quiet, easy to live with and keeps the house warm. Even without solar PV, the running costs were no more than we were paying for oil. For the first week with the solar and battery storage in place, we’ve been
within a few pence of being self-sufficient for energy – a testament to the survey and design work done at the outset.
