Fantastic episode with Barry who runs Renewable Heat up in Scotland. We discuss his heat pump journey as well as his work with the plumbing and heating association Snipef.
We discuss lots such as MCS, the NIBE PVT system, sizing heat pumps and the new service which www.heatpimpsurvey.com provides which measures rather than calculates heat loss.
We also mention how some of the old solid wall buildings are some of Barry's best performing systems.
Defrost cycles are discussed and how a heat pump can become more efficient the colder it gets outside due to lack of moisture in the air.
