Honeywell Evohome smart Heating Controls

Evohome allows room by room heating & stored hot water control.

With Evohome controls you can control the heating of individual rooms from anywhere at any time, whilst also allowing you to boost hot water as and when you need it.

Due to the fact you are able to control your heating from anywhere at any time you will also notice a reduction in wasted heating and a reduction in your heating bills too. You’ll only be heating your home when you need to which can result in big savings off your energy bills every year; this is because you’ll be able to turn off your heating if you are away from home or adjust the schedule if you’ll be home later than usual.

Our range of heating products will make home life easier as you'll be able to control your heating from an Apple or Android mobile phone, as well as from a tablet. If the plans change in your busy family life and you’re no longer home for the weekend or your kids are home earlier than expected you can pop the heating on or off. With our heating controls there is no need to change your heating supplier; our heating products can be used with any energy supplier.

Contact us directly for more details on the Honeywell Evohome heating control products we have available and if you have any questions we’ll be happy to answer those too. We can also help if you're looking for a new Vaillant or Viessmann boiler and would like to to integrate a VRC 700 or a Vitotronic 200 Weather Compensator with Evohome .

Below are just a few comments our customers have had to say about work we have carried out for them:

I have been using Graham and Interheating for over ten years. Whether its a boiler service, gas safe certificate, boiler repair or a full installation they are superb, reliable, courteous, professional and sensibly priced. They have never once in my tenure recommended work that doesn’t need doing and always consider the wider implications of the advice given. I would have no hesitation in recommending Interheating as a firm to the public or wider businesses.
— Nick D
Boiler serviced by Graham, who arrived on time, was courteous and professional, as well as answering questions and offering useful advice. Work area was left tidy. I will be using Interheating again and would definitely recommend.
