We are very happy with our new Viessmann combi boiler. We have never had a Combi boiler before but definitely recommend this one. The radiators stay warm for at least 40 minutes after the boiler goes off at night. The whole package is good as you get a mobile thermostat so you can take it to bed with you – when it is really very cold you can switch the boiler on [from bed] or if you are getting up extra early.”
