So far we have been happy with our Viessman boiler which has funtioned reliably. Sometimes the house is too warm and we have had to regulate the heat using the tempreture controls on the radiators, The Viessman seems able to provide powerful heat to all ten radiators in our house.
Many thanks and well done Viessmann.
