Customer Testimonials


“We have taken part in an extended home trial of the new EOGB boiler between April 2019 and May 2021. It replaced a 15-year-old kerosene boiler with a much lighter and more compact unit, and we were particularly keen to reduce our fuel consumption. With the previous boiler providing all the heating and hot water for a large old Cotswold stone house we were using on average 300 litres per month. Since the EOGB boiler has been fitted our usage has dropped to 200 litres per month, which will save us around £730 a year on current fuel prices. 

It’s great to see new technology reducing our carbon footprint and saving us money at the same time.”

Alistair Dinmore

“Over the last year the Sapphire has proven itself to be a reliable & efficient boiler, integrating itself well with our Genius Hub control system.

We have noticed a decrease in our oil consumption, compared to our previous boiler. It is looking like we have reduced our consumption by at least one tank fill per year, saving around 1000 litres of oil per annum.”
