Last year we ran a big survey of UK heat pump installers with @betatalk.bsky.social and @imsheat.bsky.social We couldn’t put all the data in our main report, so the team is writing follow ups. Here’s a deep dive on what installers say about skills and training www.nesta.org.uk/project-upda...

nesta.org.uk

What skills and training are heat pump engineers looking for?

We found that beyond core technical skills, installers seek training in business management, administration, and system design to support their work

Thanks @betatalk.bsky.social for a great chat. We covered a lot of ground from low energy sports centre design to the benefits of (MCS) certification despite the pain it causes.

"It's like a super-efficient electric train traveling from point A to point B, but then reverting to coal and steam for the return journey" Had a great time on the BetaTalk podcast with @betatalk.bsky.social comparing US and UK heat pump markets! We have a lot to learn from each other. #2WayAC 🔌💡

According to MCS The UK has now reached 250,000 all-time certified heat pump installations. Total # of BUS applications for Nov 24 across all technology types= 3239 WORTH NOTING: the UK has Europe's largest market for commercial heat pump systems.

Good points from @acjsissons.bsky.social on a good question from @adambell.bsky.social Heat pump tech is an well established market. Just been in station which is heated with heat pumps,for obvs reason. All these "things" inside use heat pump tech. Estimates of 5 billion compressors on the planet

UNDERFLOOR CONFUSION The recent test report from Energy House at @salforduni.bsky.social is possibly causing confusion. Just 2 radiators (1 upstairs, 1 down) could heat the whole Barrett house with low temperature. Yet it seems the UFH industry are suggesting radiators will be problematic

Drawing of a radiator which is 1200 mm long and 700 mm high. It's a type 22 radiator. The drawing also shows what the flow temperature to the radiator would need to be at four different outside temperatures: -3°C, 0°C, 5°C and 10°C. The radiator is for a heat pump system meaning the return temperature is designed to be 5°C lower than the flow temperature.

HOW QUICK IS YOUR RADIATOR It's worth remembering that power (measured in Watts) has seconds built in. Heat moves out of a home at different speeds (insulated or not) The driving force of heat into a home is the difference in temperature between room temperature & the MWT inside the radiator 1/

A diagram of a radiator 1200mm long by 600mm high. It is a type 22 radiator meaning it has 2 panels and 2 converters. Convectors are just thin pieces of metal tack welded to the panel to increase the surface area of a radiator.

The diagram illustrates the power output for different conditions. The speed at which heat leaves a radiator is determined by the room temperature and the mean water temperature inside the radiator.

The mean water temperature is determined by knowing the flow and return temperature. The mean is in-between these two temperatures...

For instance, the image shows what the power output of the radiator will be if there was a mean water temperature of 42.5 degrees Celsius. This would mean there is a flow temperature of 45°C and a return temperature of 40°C.

One the mean water temperature is know, it is the difference between this and the room temperature which denotes how quickly heat will move into a room. Knowing the power rating at different DTs is helpful in understanding how well a home can be heated with low flow temperature. Many homes can already have low flow temperatures in their heating systems in certain conditions

RADIATORS CONFUSE PEOPLE here is a video series to help people understand the science WORTH noting that new (uninsulated) homes built in the 1960s had single panel radiators which did not need a flow temperature above 55°C on an average day of winter (e.g. 9°C outside) #energy #heat

I'm in a Vic solid wall home. Putting in a HP dropped our energy demand for heating by 75%, now on par with our new build neighbours. ~2 tonnes per year CO2 saving. Solid wall ins would have been £15-20k, ~75 year breakeven
