UTP chooses Interseasonal Heat Transfer™ for its new factory at Lee-on-the-Solent

Interseasonal Heat Transfer was chosen for UTP's new 2,763m² purpose built factory at Daedalus Airfield, Lee-on-the-Solent, to provide sustainable heating in winter and sustainable cooling in summer. The new facility opened in 2016.

Precision temperature control is achieved by heating or cooling the large thermal mass of the factory floor. The floor is cooled in summer by transferring surplus heat from the factory floor down to a Thermalbank in the ground. When heat is required in winter heat is recycled back to the factory floor from the Thermalbank to maintain a constant temperature within the building.

Interseasonal Heat Transfer integrates ground source heat pumps and seasonal thermal energy storage with a sophisticated energy management system. This results in an automated system that balances the temperature in the building with the stable temperature natural to the ground by transferring heat from the ground in winter and storing surplus heat in the ground in summer: this achieves recycling of heat using precision engineering.

Universal Tool & Production Company Ltd

Universal Tool & Production Company Ltd is a precision engineering company, specialising in low to medium volume production, prototype and pre-production precision engineering projects to AS9100 Standard for the aerospace and oil & gas industries. Clients include: Airbus, Boeing, Bombardier, McDonnell Douglas, Saab.

Some components require to be made so that the bore tolerance is straight round and has to be within 0,005mm along the whole length. To achieve this, the air temperature has to be carefully controlled at the specified 68.4°F, because just 1° of temperature change, would yield 2.5 times the tolerance permitted.

Renewable Heat Incentive

The new factory, which opened in 2016 benefits from a cashback of 8.95 pence per kilowatt hour of renewable heat used from the Renewable Heat Incentive.
