Sports Hall Radiant Heating - Hoe Bridge School

Project Background

Hoe Bridge School is an independent co-educational pre-prep and prep school in Woking, Surrey. The sports hall had been heated by an old radiant system supplied some 35 years ago. The old system was past economical repair so the school decided to invest in a brand new radiant heating system. Contractor, ABS Ltd had over the years maintained the facility, so the school looked to them for advice on replacement equipment. Powrmatic were approached by ABS Ltd and undertook a thorough survey of the sports hall, with a view of replacing the old system with a new Powrmatic SRP – PCV continuous radiant tube system.

Project Solution

Although the concept of the new heating system is very similar to the old one, there are sound reasons for the like-for-like type replacement. Radiant heating in sports halls is well established as it provides an environment of uniform heat coverage without stuffiness where sports activities can be performed in complete comfort.

The new Powrmatic SRP – PCV continuous radiant tube system comprised two radiant branches, each 22m long, down the length of the hall, each branch containing 2 x PCV 23kW burners, all feeding to a vacuum fan to extract the products of combustion. This arrangement virtually mimicked the original layout to reduce the installation time and costs.

Project Result

Gas fired continuous radiant tube heating is a proven type product being the most appropriate solution for the challenge presented by sports halls, maintaining comfort levels whilst minimising fuel usage and carbon emissions.

The SRP-PCV system combusts fuel at the point of use and has the capability of modulating down to 60% of high fire whilst maintaining efficiency but reducing fuel consumption. The Powrmatic SRP-PCV system is designed and manufactured in accordance with BS EN 17175:2019 for Multi-Burner Systems and incorporates a patented burner metering device.

The Powrmatic SRP-PCV & PCV+ systems have been validated following review against government approved high performing energy efficiency criteria, with a Seasonal Space Heating Energy Efficiency (SSHEE) of greater than 90%, thus allowing inclusion onto the ETL (Carbon Trust, Energy Technology List). This high efficiency reduces energy usage, operational costs and carbon emissions.
