Dr Jon Gluyas, geo-energy, carbon capture and storage chair in the Earth sciences department at Durham University, said: "Heating water requires a lot of energy and it gives up that energy fairly slowly - so when you put that heat into the ground, it's fairly well insulated.
"It's a great way to store the energy. Over time, you set up a sort of equilibrium whereby you may only lose a few degrees as it dissipates.
"The key thing here is energy transformations and heat. If you can save heat, it means you are making the whole system more efficient. It's carbon zero and a phenomenally powerful way of overall reducing our demand on energy.
"If you get it from dancers' body heat then all the better.
"Storing the heat and playing it back is a major way that can positively influence the energy crisis in the UK and improve energy security.
"This is a really good move."
Bodyheat has been made possible with support through the Scottish government and largely subsidised from a series of grants.
Glasgow City Council convener for climate councillor Angus Millar said: "This is a fantastic scheme, where people really are making Glasgow greener - while having a great time.
"This innovative approach to reducing emissions and energy use at SWG3 is a great example of how we can all play our part in Glasgow becoming a net-zero city."
