Our customer had an old warm air unit, using an open flue chimney system.
This was removed and a new Johnson & Starley ‘Economaire’ unit installed in the same position, complete with an internal water heater.
The Johnson and Starley standard product has an inbuilt mechanical programmer for central heating and hot water timing.
At our customer’s request, we fitted a remote digital 7 day timer to the Economaire, for more flexibility in control.
