BetaTalk - The Renewable Energy and Low Carbon Heating Podcast

Send us Fan Mail

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.

Nathan chats to the MD of EOGB about a UK first - a domestic modulating oil boiler.

The boiler uses open therm to modulate the flame and will output different flow temps to the radiators or other heating emitters. 

Nathan starts the episode with a little pre-amble about the importance of flow temps constantly changing to match the demand of the property. 

Enjoy!

We are joined by Richard Burrows from Mid Wales Plumbing and Heating Supplies who is an expert on heating control strategy.

Richard talks about the types of modulation - load compensation and weather compensation and how all boilers should be controlled this way.

To understand modulation I have written an article with a funny analogy here

With advice about turning boiler temperatures down for combination boilers 'combis' Richard chats about heating systems using cylinders and how the outdated practice of piping up S and Y plans is scuppering  efficiency. 

Great episode this

Nathan chats with his friend Dave who runs and owns Condensate Pro and now Primary Pro.

Primary Pro is a polyethylene product which comes pre painted making it easier to use than class O insulation. He has also developed Bond & Seal which can be applied all weathers unlike the contact adhesive which is used for Class O.

The conversation is a useful resource for people wanting to understand the types of pipe insulation available and how to install it correctly, especially for heat pump pipework which is outside

Topics

•  weather resistance and weather proofing are discussed along with UV protection.
• polyethylene and Class O
• Nitrate Rubber Foam
• Closed cell insulation
• Clipping insulation
