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
