A BUILDING firm from St Martins has gone carbon neutral at its new headquarters thanks to a state-of the art renewable heating system.

Staff at Primoris Homes bask in premises warmed by underfloor heating fired by twin air-source pumps.

That is thanks to the £25,000 system installed by Denbigh-based green-energy experts Hafod Renewables, which now heats the two-storey building on the Bank Top Industrial Estate at St Martins.

It houses Primoris and its two sister companies, The Roofing and Salvage Depot and Pinnacle Slating and Roofing.

Director David Howell said the system was perfect for their requirements and also helped them do their bit for the environment.

"We are delighted with the system – it’s been an ideal solution for us," said David.

“We wanted to do our bit for the environment and reduce our carbon footprint and now we’re pretty much carbon zero with the air source heating system and our electricity supply from 100 per cent renewable sources.

“The heating keeps everything warm in the offices and in the canteen and the lads really appreciate that.

“We moved here to our own premises from a rented site in Oswestry and we wanted to future-proof ourselves and this system helps us do that.”

Two big Daikin air-source pumps at the rear of the building do the work of transforming an outside air temperature as low as -20C to a toasty 21C indoors via a heat exchanger system.

Hafod Renewables Managing Director David Jones, whose company are the only key partner in north and mid Wales for Japanese green technology giants Daikin, added: “Air-source was the best solution for Primoris because of building regulations and we worked alongside Daikin to design and install a twin air source heat pump system to provide heating and hot water all year round.

“The fact that it is underfloor heating is really a marriage made in heaven too because the air-source system will work much more efficiently and cheaply than a radiator-based system.

“On this site the only real alternative would be an electric system which would cost £3,000 a year more so this will pay for itself within seven years and will still be running with minimal maintenance in 20 years’ time.

“Renewable energy really makes sense for businesses because the cost is really competitive with conventional energy sources and that’s only going to improve in the future."
