Why does a heat pump need a special hot water cylinder?
Why heat pump cylinders need larger coils and the right flow rates to work efficiently.
Heat pump systems operate at lower flow temperatures compared to traditional boilers. Therefore, the design of the hot water cylinder is critical. The Climacyl range addresses these specific needs by:
- Maximising Coil Surface Area: Our heat pump cylinders incorporate coils with an exceptionally large surface area. This facilitates superior heat transfer, even with lower temperature inputs from the heat pump.
- Optimising Flow Rates: The internal coil design ensures that water from the heat pump flows effectively through the cylinder, maximising contact time and heat exchange.
- Reducing Heat Loss: High-density, foam-injected zero ozone depletion potential (ODP) insulation minimises standing heat losses, keeping your water hotter for longer and reducing the workload on your heat pump.
- Material Choice: Offering options in highly corrosion-resistant Duplex Stainless Steel for ultimate durability.
With a wealth of experience in both specialist cylinder manufacturing and renewable technology system design, World Heat Cylinders can provide the most efficient solution to meet your specific heat pump system requirements.
