Thermometer with thermowell and 3/4” bushing Available in three sizes (300, 500 and 750 litres) and five different models. CTC’s tanks store radiator water instead of hot tap water in order to ensure optimal operation of the heat pump and that you always have fresh hot water. DHW heating is accomplished via finned CTC 300/20 is able to cover the DHW needs of an average-sized house. CTC 500 is able to cover the DHW needs of up to 10 apartments and CTC 750 up to 15 apartments. They can also be cascade-connected in situations where the DHW need is greater. CTC Hot Water Storage Tank 2 - a series of volume tanks for hot water storage. The hot water storage tanks are available in three sizes (300, 500 and 750 litres) and can be interconnected to achieve the desired storage volume. copper coils, which are effectively heated by the radiator A hot water storage tank is necessary for wood boilers in order to store energy, since woodboilers often produce CTC 300/20 has a volume of 300 litres and contains a finned copper coil measuring 20 m. CTC 500/25–50 has a volume of 500 litres and contains 1-2 finned copper coils measuring 25 m. more energy than can be consumed at any given time. The size of thetank depends on the size and type of wood boiler installed. In most cases, a modern wood boiler requires a storage volume of at least 1,500 litres. Key features • Suitable for most energy sources • Ensures optimal heat pump operation • Well-insulated for lowest possible energy loss • Available in three sizes: 300, 500 and 750 litres • Hot water heated via highly effective finned copper coils Go Geothermal Ltd Ridgeway, Newton Aycliffe County Durham, DL5 6SP Tel: 0
