The works consisted of replacing 4 boilers.
To maintain the central heating and hot water service it was necessary to carry out the installation by changing boilers one at a time. This meant that 3 boilers were online at any time, and when the new boilers were connected the flow and return gas condensate were adjusted.
The flue was serviced and the electrics reconnected to the BMS system. The system was partly flushed and inhibitor was added.
