Heat Pump podcasts I imagine a few and far between. This one likes to meet the engineers installing heat pumps, solar thermal systems etc. to see and understand the challenges which they face. Engineers are at the front line of installing renewable technology and have different vantage points to other cohorts interested in reducing CO2 emissions and reaching net zero targets.
- 01:25 Ken discusses how consumers are becoming more aware of the low carbon and renewable technologies available to them
- 02:49 Leia from Your Energy Your Way chats about the RHI and whole house retrofit and the cost of a heat pump
- 04:10 Rob from Solarflair education of heating engineers
- 05:30 Nathan mentions how the gas industry has trained engineers and how high efficiency boilers are not efficient if on inefficient heating systems
- 07:06 Leia - changing radiators for heat pump systems and the importance of rom by room heat loss calculations
- 08:23 wet heating systems and how many radiators are oversized and perfect for low temp heating systems
- 10:00 fabric first and the second law of thermodynamics
- 10:35 heat pumps matching heat loss and insulation requirements. Hybrid and bivalent heating systems
- 11:35 High temp heat pumps and MCS rules
- 12:09 MCS accreditation and the struggle with DNO form filling
- 14:00 DNO District Network Operators and Energy Network Association
- 16:46 Concerns with overload and amps. AC and DC and Substations
- 19:44 A 12kW heat pump does not require a 12kW electrical supply
- 21:06 COP goes down in the winter, low temp heating systems and heat calculations
- 24:11 Solar heat and solar thermal hybrid heating systems. Glycol stagnation and refract testing
- 26: 35 Integration of solar thermal with buffer tank and buffer size
- 29:30 Airing cupboard and roof space for heat pumps and how solar thermal is more efficient than PV with small roof space

00:30 Heat Pump manufacturer training
01:58 Heat Pump supply chain issues. Heat Pump and solar thermal technology is not ordinarily stocked in plumbing merchants. Getting it delivered often involves extra contingency and logistics.
05:36 Solar Thermal suppliers and the issues with obtaining solar heat components
08:35 Why heat pump engineers often have to add on price
09:45 Heating engineers are now self employed, does this cause problems? Will there be a shift back to employed heating engineers. As Leah explains installing a variety of technologies within a hybrid heating system e.g. (solar thermal with solar PV with battery storage with heat pump) may better suit an SME rather than a sole trader.
14:12 Nathan speaks about his specialist topic: training.
18:12 Are we training to many people to get diploma certificates (not full qualifications)
21:00 Most plumbers and heating engineers are self employed. They don't tend to be able to take on apprentices (students who will gain an NVQ). If they do take on an apprentice it is usually a family member e.g. daughter, son, niece or nephew.
24:00 Apprenticeships are not always a great way to learn if bad habits are being transferred.
30:00 Control of heat pump systems. Weather compensated control on heat pumps. Some heat pump manufacturers controls work with agile tariffs. How they can load the buffer tank at different times. How some of the good engineers do not like microclimating with zone control. Agile, load shifting, smart control technologies working with solarheat and batteries. Car charging and powerwall
35:00 Will heat pump system installs be scalable and the problem with installing a system in the summer.
38:00 The problem with boiler scrap-age schemes, the problem with the average boiler install.
40: 00 Ken mentions the H word. Hydrogen boilers. Hydrogen does not seem to be suitable for the grid and engineers discuss better uses for Hydrogen.
44:00 Low temperature heating systems. Low temp ready heating systems. Heat pump ready cylinders.
