Marine source heat pump appreciation society meeting. Portsmouth Harbour – here’s one we made earlier

Portsmouth Harbour is the proud owner of a 200kw sea water based heat pump and also chiller. Not many heating system meeting have their own aircraft carrier!

Tue and it was Portsmouth Harbour for a meeting with the Rory the engineer in charge of the largest marine source heat pump in the UK. We had drawn together a gathering of a small and exclusive team. People working on marine source heating systems. For those of you who have been following the blog will know of the National Trusts aspiration to install a system in the Menai Straits to heat the oil guzzler that is Plas Newydd. We had also invited Robert from the RNLI who have 4 years of experience of small systems installed at a few lifeboat stations spread across the UK and Andy and colleagues from Pool and Bournemouth University who also have aspirations in this direction.

interesting learning lessons from this system. Pump type, debris filters, servicability are the main ones

interesting learning lessons from this system. Pump type, debris filters, type of metal or plastic, serviceability, flow rates are the main ones

…and what of the system? My overall impression was that of simplicity and why wouldn’t you? The main lessons are use people with sea water experience for the sea water bit. Fouling, filtering and pumping need to be detailed and specified correctly. Also think of serviceability. Robert from the RNLI had a lot of experience on weld durability, metal types, anti fouling and so on because of their day jobs with life boats. It was a good morning and gave a lot of detail of what we should be looking for but also a nice peer group to test our design and specification with

elegant and simple. pumps in the harbour move the water to the inline filter. From there on to the twin tube heat exchangers through to the heat pump and then round the building. Whats not to like? ps they are getting a COP of 4.5! (one unit of electricity for 4.5 units of heat)

Elegant and simple… pumps in the harbour move the water to the in-line filter. From there on to the twin tube heat exchangers and on through to the heat pump and finally round the building. Whats not to like? ps they are getting a COP of 4.5! (one unit of electricity for 4.5 units of heat)… we need to get the detailing right and make the system durable and serviceable.
