Two new Vaillant 656 light commercial boilers.
Utilising the latest Vaillant control ebus connections, ensuring both boilers can be utilised to suit heating demand or one at a time.
The controller also ensures that each boiler gets exactly the same number of hours of use. Both boilers are plumbed through a low-loss header.
This maintains a constant flow rate through the boilers, ensuring smooth operation and efficiency.
A large system filter was also installed to prevent any particles from the old central heating system from entering and damaging the new boilers.
These two boilers replace one ageing boiler that was proving uneconomical and kept breaking down.
The removal of the old boiler and replacement took three days, with the flat owners only being without heating and hot water for two working days
