Effectiveness and economy make Reznor heating a hit at Marymount School

Heating the sports hall to comfort temperatures for sporting activity, examinations or large social functions is easy since a Reznor heating system was installed at Marymount International School. Quick to reach constant temperatures, quiet and economic, the system matched all the school’s requirements.

Marymount International School, in Kingston upon Thames, Surrey, is a girls’ private day and boarding school offering the International Baccalaureate Middle Years and Diploma Programmes for 11-18 year olds. Established in 1955, the school aims to meet the educational needs of families in the international business and diplomatic community. Some 50 different nationalities are represented at the school.

Sports are a significant part of the daily curriculum. Activities offered range from soccer and hockey to basketball, volleyball and tennis. Many of the sports take place in the school’s own sports hall, which was built in 1984. The sports hall was originally heated by a ducted air system that, over the years, had become increasingly ineffective for purpose.

The school approached Reznor UK Ltd, seeking a system that was effective and economical, but also quiet enough to allow students to take examinations in the sports hall.

Reznor, working with R A Green Mechanical Services of Crowborough, East Sussex, supplied an lpg-fired RPVE unit heater, linked to a pvc Air Mixing™ duct within the building.

The RPVE was mounted externally on a specially designed steel frame at mezzanine level on the end elevation. The lpg is supplied from an underground gas vessel close to the building and landscaped to disguise its appearance. The gas is piped up to the heater; warm air is then ducted up to a higher level and forced down into the building.

The single-leg Air Mixing duct runs the length of the interior – approximately 30metres. Warm air is forced out of tiny perforations all along the duct, producing an immediate mix with room air and eliminating temperature stratification.

The Reznor heater is equipped with motorised dampers to allow full fresh air intake when ventilation is required, or up to 90% re-circulated air when economy is a priority.

David Schuchter, Head of Sport at the school, comments: ‘The heaters work very well. It’s easy to teach while the system is switched on.’
