ELCO supplied 24m2 of AURON® DF evacuated tube solar collectors and a 1380 litre solar buffer vessel, along with an Ultramax 85kW wall-mounted condensing boiler and pressurisation manager to the new Rayleigh Weir fire station in Essex.

With sustainability and energy efficiency at the heart of the fire station’s design, the solar thermal system complements a ground source heat pump and innovative design to create a very green building.

The £4.5 million building is being built by Mullaley and Company, designed and project managed by Hunters and incorporates a single-storey four-bay garage, a training tower, and a two-storey administration and accommodation block. Basildon and Castle Point Community Command will also be based there, providing fire safety and administrative functions. The station will also provide a home for youth schemes to help with the behaviour of youngsters who have had difficulties at school or have been involved in crime.

The solar thermal installation was completed by MHS Boilers’ preferred installation company TCS Group. TCS Group’s Technical Sales Director, Simon Simmons said: “The evacuated tubes from MHS Boilers were very easy to install, and thanks to their clever design, can be oriented to provide the optimum angle to the sun. The free energy generated by the sun will add to the already strong green credentials of this innovative building.”
