Water source Heat Pumps are by far the most efficient form of heat pump technology available. Energy for Water Source systems can be extracted from lakes, rivers, wells and boreholes. They require a slightly different heat exchange process to extract the energy for heating and hot water supply.

Ecosaveit provide full installation, servicing and maintenance services for your water source heat pump system throughout Warwickshire, Leicestershire, Worcestershire, Staffordshire,Oxfordshire, Gloucestershire, Cheshire, Wiltshire, Hampshire and Nottinghamshire.

How We Work

We offer an End to End service with 5 defined phases, ensuring your project runs with ease from start to finish.


We’ll start by meeting with you to discuss your project.


Once we’ve ascertained the scope of the project, we’ll put together a custom quote for you.


We’ll then produce schematics of your system and send your options to you for approval.


We will install your system using the most up to date technologies and techniques.


On completion, we will conduct your system commissioning, signing your system off as complete.


Using water directly or indirectly through a heat pump provides the highest energy extraction. This is why Water Source Heat Pumps are the most consistent and efficient way of transferring energy into your heating and hot water system. 

The Heat Pump Cycle

The Heat Pump Cycle is built up of 4 Phases.

Phase 1- Evaporation:

By means of a heat exchanger, the liquid refrigerant extracts renewable energy from the heat source (air, ground or water) and evaporates the refrigerant into a gas.

Phase 2 - Compression:

By the introduction of electrical energy, the now gaseous, but still cold refrigerant, is compressed in a compressor and thus heated. The refrigerant leaves the compressor as a hot gas.

Phase 3 - Liquefying/ Condensing:

The hot gas now reaches the condenser and transfers energy into the heating system. During this energy exchange the gas condenses and leaves the condenser as warm fluid refrigerant.

Phase 4 - Decompression:

The warm fluid refrigerant is now transported to the expansion valve. As the refrigerant passes through the expansion valve, a significant reduction in pressue lowers the refrigerant temperature without any loss of energy. The cold fluid refridgerant is then reintroduced into the evaporator and the cycle begins again.
