Installed externally at high level into the flues of two gas fired boilers, these units each gave a 5.2% reduction in gas usage.

In addition, when operating only one boiler, the economiser gave an extra 5% increase on the MCR thereby giving extra time before having to bring in an additional boiler.

This installation won a British Gas Gem Award for the client.
