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
