Marianne and Jim’s Central Heating and Pressurised Hot and Cold Water System

After servicing Marianne and Jim’s heating and hot water system for many years, they decided to upgrade the system to ensure reliability longer term and to improve efficiency. 

After servicing Marianne and Jim’s heating and hot water system for many years, they decided to upgrade the system to ensure reliability longer term and to improve efficiency.  We decided to install an ATAG system boiler with Joule high gain unvented hot water cylinder.   With the central heating pump now downstairs within the boiler the system is now quieter in operation.  The system is installed with ATAG’s One Zone controller with weather compensation and hot water priority. The boiler understands the temperature within the cylinder and uses ‘bottom up’ modulation to manage the flow temperature to ensure the cylinder is heated as quickly and efficiently as possible. This is useful when properties have variable hot water use (i.e. guests visiting).   When the boiler switches over to space heating the weather compensator manages the flow temperature ensuring that the radiators give the right output to overcome the heat loss from the building. This means that the condensing boiler will actually condense, making the system more efficient and the room temperatures more comfortable.  We have since been back to service the system and also to replace their water softener.
