How it Works


EcoSpring Heat Pump Hot Water Cylinders work much like a fridge but in reverse. They harness the ambient temperature in the air, multiplying this energy to heat the water at a fraction of the operating costs of a traditional hot water cylinder.

You will need mains water pressure.


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 & returns back to the evaporator for the process to start again.


Mains Pressure Required

1.0kW Electricity Input + 2.60kW Atmospheric Heat Input = 3.60kW Hot Water Output

A heat pump is like an energy amplifier. From 1 kW of power input, it 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.
