Pub chain Marston’s continues to leave no stone unturned in trying to make its kitchens as energy efficient as possible – but finding a heat recovery system that ticks all the right boxes is posing a particular challenge for the business.
The group, which numbers 1,600 pubs, has successfully cut its total energy emissions by 3.7% last year and remains committed to further reducing its carbon footprint in the coming years, with £1m to £2m of energy reduction-related investment planned, according to its latest accounts.
It is interested in exploring how heat captured from kitchen canopies can be used to reduce wastage or converted into hot water.
Andy Kershaw, group head of facilities and capex at Marston’s, said that a heat recovery system which “isn’t riddled with complexity” is one solution that it would love to find.
Marston’s has trialled different equipment, but Mr Kershaw said it had not quite found what it wants.
He said any supplier with the “perfect” solution was welcome to email firstname.lastname@example.org with details.
“We are always looking at the most innovative things. We will absolutely respond to everyone but it might be a ‘no’ because we have seen it before.”
Pressed on other areas where suppliers could add value, Mr Kershaw stated the industry would benefit more from connected appliances if there was compatibility between systems from competing manufacturers.
“Everybody is telling us now that they can have connected equipment but they all have a version that only works with their own equipment. We want one system that we can put into a kitchen that will talk to every single piece of equipment, log all of our temperatures etc.
“We want to pay once for a hub and then have that same technology in every piece of kit. Whilst suppliers keep going off in their own direction, it is almost like VHS and Betamax; there needs to be some kind of open protocol.”
