The aim of the design stage is to turn the outline specification produced at the feasibility stage into a full system specification and set of drawings so the system can be built.

The main areas covered at the water source heat pump design stage are:

• Detailed specification of all Mechanical & Electrical (M&E) plant.
• Electrical installation drawings and specification (upgrades, power and signal wiring).
• Plant room layout.
• Intake system drawings.
• Integration with existing thermal systems / back-up and boost heating / supplementary heating.
• External pipe runs / trenches and ducting / pipe specification (for source water).
• Internal pipe runs in plant room (to heat distribution).
• Design of civil engineering / building works (if applicable for intake and/or plant room).
• Control system specification.
• Heat emitter specification – (note detailed design of this aspect would be done by the chosen plumber / heating contractor).
• Operational performance and financial modelling.
• Draft sequence of works / project plan.
• MCS paperwork package, for Renewable Heat Incentive (RHI) certification.
• Construction Design Management (CDM 2015) documentation as the Principal Designer.
• Budget costing.

Water source heat pump installation

The extent of the work depends a lot on the type of building and size of the project. For a domestic water-source heat pump project the intake can be a small area created for a small pump that that pumps water to a primary heat exchanger and then the source water is discharged back into the watercourse.

A pipe run then conveys the water to the heat pump location. If the heat pump is accommodated in an existing building no further building work will be needed and the remainder of the work is plumbing and electrical installation. Renewables First oversees the whole installation process and is responsible for the design being followed and the efficient operation of the finished system. We either use trusted plumbing and electrical contractors, or can work with your own plumber and electrician, which often has advantages if they already have a good understanding of your building.

Larger domestic and commercial projects often require a more substantial water intake structure because of the increased volumes of water used by the system. In-river constructions works are likely to be required, and with many years’ experience installing hydropower projects this is something Renewables First is very familiar with.

Also larger projects may need a larger or new plant room, which may require some building works. Again once the building works are completed the work moves into Mechanical and Electrical (M&E) installation and at this stage we use suitably experienced contractors or work with your preferred contractors. Once installed Renewables First will commission the water-source heat pump system and make sure it works efficiently in your building and provide ongoing support through our Operation & Maintenance (O&M) services.

Are you considering a water source heat pump project in the UK, Ireland or overseas?

Renewables First have considerable experience and full project capability, from initial feasibility study through to system design and installation.

The first step to develop a water source heat pump project is to conduct a full feasibility study.
