The Existing Situation.

Gtechniq wanted to develop a purpose-built detailing centre to showcase their range of protective vehicle coatings for paintwork, wheels, trim and glass. The new workshop heating system not only needed to provide a good level of thermal comfort for the detailers working on the vehicles but also aid the detailing process.

The Challenge.

Gtechniq’s goal was to develop a world class detailing centre which provided the pinnacle of vehicle preparation and delivered breath-taking results. To achieve this goal the workshop heating solution needed to be non-intrusive, aid the application of their protective coatings, reduce the circulation of dust particles which would stick to the coatings and, finally, cut heat loss when the large roller-doors were opened to move the vehicles in or out of the centre.

The Solution.

The ETHERMA Thermocassette infrared heating panels provided an ideal workshop heating solution. These flush-mounted ceiling panels were seamlessly integrated within the suspended ceiling grid maintaining the clean, minimalistic look required by Gtechniq.

Unlike convection heating, the infrared heating panels directly warm objects (floor, walls, people, vehicles, etc.) not the air. Warming the cars allows an easier application of the protective coatings, whilst the coatings themselves dry quicker. Infrared heats the room evenly, reducing the temperature gradient between the floor and ceiling (0.5°C- 1°C difference) which minimises convection currents and the circulation of dust particles which could stick to the coatings and spoil the high quality finish.

By warming the thermal mass of the detailing centre, the energy consumed (and paid for!) is stored in the building itself and therefore not lost when the large roller-doors are opened – as is the case with convection heating. Additionally, staff enjoy the uniform heating offered by infrared rather than hot and cold spots which are associated with convection heating.

The Solution in Detail.

The infrared workshop heating system comprises of 24 ETHERMA Thermocassette TC-300W infrared panels evenly distributed across the 150 m2 suspended ceiling. The panels are controlled by a hard-wired eTOUCH mini programmable thermostat which can switch up to 16 Amps or 3.8 kW of heating. With a heating load of 7.2 kW it was necessary for the thermostat to switch the infrared heating panels through an electronic relay system.

The in-ceiling infrared panels are ideally suited for full heating or zone heating in ceilings up to 3.5m high and give an even heat distribution, maximise the amount of floor space available and reduce the risk of damage from accidental impact.
