Water Source Heat Pumps

Water source heat pumps work by absorbing the heat from the sun which is stored in bodies of water such as lakes or rivers. A system of flexible pipes containing fluid is laid in water. The fluid absorbs heat from the surrounding water as it passes through the pipe and carries it straight into your home.

High year round water temperatures allow water to water heat pumps to provide very high levels of efficiency with CoP’s of 5 or over achievable.

Underground water stores an enormous amount of solar energy which can be extracted at very high levels of energy efficiency by circulating it directly through the heat pump evaporator.

The Benefits of Water Source Heat Pumps:

• Energy Efficient Heating – You can heat a whole house, generating temperatures of up to 55 degrees
• Cost Effective Energy - Heat pumps provide the lowest and most consistent running costs against conventional systems
• Reduced Carbon Emissions
• A choice of installation – pipes can be laid to suit space availability

In addition water source heat pumps are ideal for new builds, highly insulated renovation buildings and houses with underfloor heating

Water source heat pumps do incur slightly higher installation costs than other types of heat pumps and do require space, good depth and some flow of water to refresh heat collection. Lake Source heat pumps have lower running cost and can capture better temperatures from ‘refreshed’ water.

The following information ‘check-list’would be helpful in assisting us to size your water source heat pump: -

• Drawings of the building - especially for a new house build or housing development but also for existing house
• The amount of water there is for loops
• How the building is constructed, in particular level of insulation and glazing
• Your current heating system or solution you re proposing to use, e.g., underfloor
