Latest Testimonials

Below are just a few testimonials left by our most recent, satisfied customers.

“My first bill after the install backed up what Adrian had promised. I’ve reduced my heating bill from £85 (with four night storage heaters) to £45. I’ve had both units running for 3 hours in the morning and evening for exactly one month. That’s a 47% reduction in my heating bill.”
Richard Nichols
“Just have to say that i’m 100% impressed by how much this air source system has transformed my 18th century cob building. We had night storage heaters that were costing around £160 per month and we hardly ever felt warm. Now I find myself getting too hot!”
Steve Wilce
“I previously had night storage heaters that were rubbish and too expensive to run. Now we have instant warmth! Duchy Eco Heating are the cheapest suppliers and installers in Cornwall, and I know that because I rang around everywhere and nobody else could beat their quote.”
Claire Taylor
“We have had this air source for over a year now and we are very happy with the system and the service, have mentioned it to friends as we have saved a lot of money on heating. I highly recommend these guys.”
Stephen Salt
“I had this installed just before lock down and we used the cooling aspect of it more than the heating but just recently the weather changed and WOW, we actually got too hot too fast so had to turn it down very quickly! Very impressed.”
Joe Murray
“Had this system installed a while back now and I’m lovely and warm. Nothing was to much trouble. Polite and very helpful and always on time with servicing. Very good company recommended Adrian to four of my friends.”
