Water Source Heat Pump

What are Water Source Heat Pumps and how much can they save your business?

What is a Water Source Heat Pump?

  • Water Source Heat Pumps use the energy stored in a water source to heat your home and provide hot water all year round.
  • It is based on one simple principle, heat transfer – using a small amount of energy to transfer low-grade heat from the water to high-grade heat, heating water to high temperatures. Essentially transferring heat from a ‘free heat source’, like the water, to a ‘heat sink’, like your home.
  • Pipes are submerged in a river, stream or lake where temperatures remain at a relatively constant level of between 7–12°c.
  • Water Source Heat Pumps can be installed as either an open or closed loop system:
    • An open loop system uses ground water from a lake or well. The water is extracted and fed directly into the heat pump where the energy raised through compression is extracted as heat. This increased heat is transferred by the heat exchanger to your property’s heating/hot water system where it is readily available for use. (In this type of installation, you may need environment agency consent to extract and discharge water from these sources, however, Ecovision can advise and manage this application for you when required).
    • A closed loop system uses a refrigerant in a closed loop to transfer energy/heat from the water source, e.g. a lake. Pipes are laid in the lake in which a liquid refrigerant absorbs the water’s heat and transfers this heat to a heat pump located inside the house.

Why Install a Water Source Heat Pump?

  • Save up to 50% on your energy bills
  • Improve your heating efficiency – With a Water Source Heat Pump 1kW of electricity will produce up to 4kW of heat energy, reducing your carbon footprint and saving you money
  • Reduce your carbon emissions and help in the fight against climate change
  • Earn through the government Renewable Heat Incentive

Frequently Asked Questions

Water Source Heat Pumps can reduce your annual heating and hot water bills by up to 50% against fossil fuel alternatives and often pay for themselves within the grant period set out within the 20 year period of the Renewable Heat Incentive.

However, each and every property is different so upfront cost, bill reduction and your ROI is never going to be a one answer fits all.

What is the Renewable Heat Incentive?

The RHI is a Government backed scheme which pays the owner of a renewable technology, such as a heat pump, for generating renewable energy on site. To qualify for these quarterly payments, which last seven years, you will need to use an MCS accredited company – such as Ecovision – and ensure your MCS accredited product is installed to MCS standards.

The MCS (Microgeneration Certification Scheme) is there to ensure the system is safely installed by professionally qualified installers and performs to the standards required by the Government.

How Long do Water Source Heat Pumps Take to Install?
The installation of a Water Source Heat Pump can take anywhere between 4 weeks and 16 weeks, depending on the size and complexity of the pump location. As there are many elements that come together during this process Ecovision offer an all-inclusive installation, including everything from digging the trenches to commissioning the Water Source Heat Pump.
Do I Need to Coordinate Other Trades on Site?
No, Ecovision can undertake the entire installation, providing the complete design, supply, installation and commissioning of the system, without any need for third parties or subcontractors.

During Ecovision’s many years of business we have found the biggest issue for customers is ensuring that everyone knows what and when their responsibility starts and ends. We have found that by offering the complete installation we ensure that we remain in control of the whole process as well as being entirely responsible for the successful completion of the installation with our in-house installers reporting directly to Ecovision.

Do Water Source Heat Pumps Require Alot of Maintenance?

Generally Water Source Heat Pumps require very little maintenance, as they are a sealed unit, much like your fridge. Though it is recommended that you inspect and clean your Water Source Heat Pump annually, clearing any build-up of leaves or debris from behind the unit.

Ecovision can complete this task as part of an annual service, leaving you with absolutely no maintenance requirements.
