What our customers say about us
- David
This is a company with great customer service and competitive pricing which provides a service nationwide. From the initial phone call enquiry to having the unit delivered, immersion heater removed, and Thermino 150e installed, the email and phone communication was great. The installation was booked within 2 weeks. I have now saved loads of space by putting my washer and dryer into the cupboard where my Thermino is. The company also went above any beyond their normal job role by providing and installing an updated timing switch and the installation of a tee valve to relocate my washer. Thanks to Ben and his team for a great service.

Ecosmart Heat has fitted a Sunamp heater for me. It was done very efficiently, turned up on time etc. Sorted out little problems on the way (getting it to work so that I can use either my existing oil boiler if I want, or the electric, and sorting a problem with the wiring). Also much cheaper and more helpful than a nearer supplier.
- Andy
Excellent service from start to finish. Contacted Ben who talked me through the process and organised delivery and installation of Sunamp. Even squeezed me in before Christmas, which was very much appreciated. Richard came first thing as promised to install, explaining the process of the fit, making sure I was happy with everything. Very friendly and accommodating guys would definitely recommend their service and product. Many thanks Andy.
