Testimonials from Clients

“Exceptional Heat Pump Expertise!”

We had a few quotes from different installers but Gary and his team knew more about heat pumps then any of the others. I was so pleased to be able to keep my cast iron rads which other people said I would have to rip out!! We are so warm and feeling smug about the savings we've made. Also his team were really polite.

“OCHSNER heat pumps are exactly what we needed"

Our move to renewables from a gas reliant freezing cold leaky old house was never going to happen until we found OCHSNER. It totally changed our renovation and has made our home so much nicer to live in over the winter. We used to say we survive the cold months now its actually comfortable.

"Silver bullet for planning permission"

The Big Heat Pump Company helped us get through the listed property minefield. Without the super low noise levels of the Air Hawk we were never going to be able to remove the old oil heating system. The fact we don't have to have an out door unit attached to house meant it sailed through planning, they called it a silver bullet! I've gone for a dark green evaporator and couldn't love it more as it blends in with the garden so well. Thank you Gary and Jay for looking after us.

“Great Communication and Project Management”

The communication throughout the project was seamless. Gary designed our heat pump and solar install and worked with our main contractor brilliantly. I was especialy impressed with his team who were much more capable then other people we had on site.capabilities.

“Friendly & Knowledgable"

The Big Heat Pump Company helped us decarbonise our church to future proof it for generations to come. As part of a three step plan of lighting LED changes, solar panels and battery storage we included two OCHSNER heat pumps. Through this work, the church expects to see an 84% reduction in emissions by saving 60 tonnes of CO2 each year.​
St Peter Mancroft is now recognised by The Church of England as a Demonstrator Church as an example for all churches striving to meet the CofE's Net Zero 2030 ambition.
