Main Contractor: Wessex Water

Monkey Island Estate is a 4 star hotel situated on a small island in the middle of the river Thames. I was tasked with the refurbishment of the 2 plantrooms.

Extremely complex system using the river water via heat exchangers to heat up or cool down (depending on the time of year) the glycol coming back from the water source heat pumps in each plantroom. The biggest challenge was that the hotel was still open to the public and still wanted hot water, heating and chilled.

I had to plan future works and communicate with the hotel manager to find out when it suited them for us to do a shutdown.

We installed new heating and chilled buffer vessels, hot water cylinders, pumps, heat exchangers, pressurisation units, expansion vessels and pipework (316 Stainless steel Mapress). The water source heat pumps were used as the primary heat/chilled source with air source heat pumps being used as a back up or if there was high demand.

I gained a lot more of an understanding of how heat pumps work and the parameters needed for them to work efficiently.
