Under plans, engineers will install heat exchange devices in a Roman-era drain carrying hot spring water to the famous Roman baths. They will transfer the heat into renewable energy.
Alix Gilmer from the Abbey told Premier: “It’s very tried and tested technology. It’s called a heat pump system. We’ve got some really good people working on it.”
The work forms part of the £19.3 million Footprint project which will also see the dilapidated Victorian-era heating system ripped out and the crumbling floor replaced.
Alix Gilmer added: “In the centre of Bath, there’s the Roman baths; the water from that goes in what was the old Roman drain through the city and down into the River Avon.
“So, it’s not being used at the moment as a resource for heating in anyway.”
An estimated quarter of a million gallons flows through the Roman baths every day.
It is hoped the scheme could eventually provide 1.5 megawatts of continuous energy – the equivalent of powering five hundred homes – to support a 200kW ground source heat pump system.
Engineers say disruption to York Street will be “minimal” while work to install the heat exchange devices underneath the road gets underway.
