Commercial boiler replacement

The existing system

The existing heating system at LTI Metaltech, Milton Park, Abingdon, used two floor-standing commercial boilers.

The replacement

We replaced the old boiler system with two Vaillant ecoTEC Plus 64kW commercial boilers on a cascade frame, with a shared flue through the existing external-wall opening.

The new installation included a plate heat exchanger to separate the boilers from the existing heating circuit, individual magnetic filters and new connecting pipework. The system connects to the existing heating pipework and controls, retaining the building’s existing zones.
