CTC AT Hot Water Storage Tanks

A storage tank can be combined with a ground source heat pump or an air-to-water heat pump if you have a high demand for water and/or hot water. Loop tanks for the efficient heating of domestic hot water, 300-750 litres, and volume tanks for the accumulation of hot water, 300-1000 litres.

CTC AT is a series of buffer tanks designed for almost all types of energy sources. They are available in several models and sizes, and can also be combined to fit most heating systems and properties. All tanks are well insulated with polyurethane/mineral wool for the lowest possible energy loss.

CTC AT 1
Coil tanks for efficient DHW heating. They are available in three sizes - 300, 500 and 750 litres - and in no less than five different models. CTC's tanks accumulate the radiator water instead of the domestic hot water, so that the heat pump operates as favorably as possible, and you always have fresh domestic hot water. The domestic hot water is heated via finned coils which are efficiently heated by the radiator water inside the tank.

CTC AT 300/25 has a volume of 300 litres and contains a hot water coil measuring 25 metres.
CTC AT 500/25–50 has a volume of 500 litres and contains 1 to 2 coils measuring 25 metres.
CTC AT 750/50–75 has a volume of 750 litres and contains 2 to 3 coils measuring 25 metres each.

CTC AT 300 is able to cover the hot water needs of an average-sized house. CTC AT 500 is able to cover the hot water needs of up to 10 apartments and CTC AT 750 up to 15 apartments. They can also be cascade-connected in situations where the hot water need is greater.

CTC AT 2
Volume tanks for hot water storage. The hot water storage tanks are available in four sizes (300, 500, 750 and 1000 litres) and can be interconnected to achieve the desired storage volume.

CTC AT 500 and 750 are also available in 6 bar versions for systems requiring higher pressure.
