Yes, you'll be fully in control of the temperature in your home. You'll have a heating programmer and thermostat as you would with a normal gas central heating system.
It's important to bear in mind however that your in home heating system will only be able to reach the design temperature which you should be able to find in your Heat Supply Agreement. If you can't see the design temperatures in your Heat Supply Agreement just contact us by email at help@watkinsenergy.co.uk or by phone on 0330 324 0018 and we'll be able to let you know.
