Combat Case Study: Freddie’s Flowers, London

Following on from rapid growth during the Covid-19 pandemic, Freddie’s Flowers needed a larger warehouse in addition to its current unit in Isleworth, London. The company called on Combat Heating Solutions for an energy efficient heating system for the new warehouse near Heathrow which is four times bigger than the previous unit.

Combat Heating Solutions supplied an energy efficient heating solution for Freddie's Flowers

Freddie's Flowers employs approximately 130 staff who work shifts enabling the factory to function 24 hours a day distributing up to 52,000 boxes of fresh flowers to subscribers every week.

The new warehouse was empty when it was bought and lacked an energy efficient heating system that kept staff warm whilst they were packing boxes.

Combat Heating Solutions Ltd were able to provide the ideal solution in the CoRayVacradiant tube system which offers a bespoke design allowing for the constraints of the building structure. Combat designed a heating system to facilitate the packing area and the rest of the floor space as the roller shutter door to the entrance of the building needs to be kept open for deliveries and vehicle loading. Radiant was the only heating option that allowed this indoor/outdoor ambiance as a warm air system would be constantly flowing out of the door and heating the external atmosphere. The system was installed by Hevac Services Limited

CoRayVac is an energy efficient system due to its vacuum operated, burners-in-series design, combined with its ability to condense. Lowering exhaust temperatures puts more heat in the space, less wastethrough the exhaust, helping result in additional efficiency and fuel savings. Burners regulate the air-to-gas mixture to achieve the optimum ratio for clean, efficient stoichiometric combustion. Models are available with inputs of; 10, 15, 20, 25 and 30 kW. Burner features include: three-try, direct spark ignition, pre-purge, filtered combustion air and cast-iron burner head.

Unique, revolutionary newdeep-dish, wide parabolic design, continuous aluminum reflectors maximise 100% reflection of the energy emitted by the radiant tube down to the floor. End caps and continuous reflectors keep tube convective heat losses to a minimum and consequently the heat exchangers retain more heat for emission. The system utilises heat treated aluminised steel tube which radiates the warm, gentle, radiant energy.

The continuous CoRayVacsystem is an excellent way to maximize heat distribution to virtually eliminate hot/cold spots and provide the utmost in comfort. The combination of gentle, even heat results in one of the most efficient and effective gas-fired, low-intensity, Radiant Heating Systems in the industry today.
