Comments From Our Customers

Eco Smart Heat Testimonials

  • Very pleased with Eco Smart Heat. From the initial enquiry through to planning, delivery, installation and handover the service was excellent.

    Rare these days to find such a great company that offer prices that could not be matched anywhere else.

    Steve Kirby
  • Ecosmartheat have 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.

    Ruth Blake
  • Very Pleased with the fantastic job done by the guys. They installed our Sunamp heat battery in 2 days including removing old heating system, radiators, tanks etc with minimum disruption and a thoroughly professional attitude.

    Excellent problem solving too working out our antiquated old system. Best thing, all the work was covered by the original quoted price, no hidden extras.

    Thanks very much Eco Smart Heat. Highly recommended.

    Vic W
  • 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.

    Andy
  • 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 & 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.
