How it Works

​EcoSpring Heat Pump Hot Water Cylinders work much like a fridge but in reverse, instead of generating cold, it generates heat! They harness the ambient temperature in the air, multiplying this heat to heat the water at a fraction of the energy of a traditional hot water cylinder. Compared with solar hot water heaters, the EcoSpring unit heats the water even when it’s dark outside and with a purchase price well under solar, it the smart choice to save energy and money when heating your water.



 A fan pulls in air, containing heat energy,
across the evaporator. 

 The evaporator turns the liquid refrigerant into a gas.

 The compressor converts refrigerant into high temp / high pressure gas.

 The hot gas inside the condenser coil heats the water inside the tank.

 The refrigerant reverts back to a liquid after heating the water & continues back to the evaporator for the process to
start again.

The Energy Equation


The EcoSpring Heat Pump Hot Water Cylinders are like an energy amplifiers. From 1 kW of power input, they can create over 3.6kW of output heat. That’s a performance efficiency of over a remarkable 300%. Conventional electric storage water heaters can only convert 1 kW of input power into 1 kW of output heat.
