Air to Air in Domestic Properties

Expanding Horizons: BetaTalk's New Newsletter and Website!

We're thrilled to announce that BetaTalk is growing! In addition to our regular podcast episodes, we're launching a brand new newsletter and an associated website. This expansion will allow us to bring you even more in-depth content, industry news, and valuable insights into the world of heat pumps and sustainable building.

Our newsletter, launching shortly, will be your go-to source for the latest industry developments, insightful opinion pieces from the third sector, and crucially, real-world heat pump case studies from experienced engineers in the Guild of Master Heat Engineers. This is an exciting step in our mission to inform and empower.

As Chris Stark, former CEO of the Climate Change Committee, remarked about this new venture: "Nathan is one of the UK’s clean heat leaders, so I always watch him closely. This collaborative media venture is an exciting next step. We need positive voices like Nathan’s to help broaden knowledge around retrofit and heat pump installations."

Episode Notes:

Welcome back to BetaTalk! In this fascinating episode, we delve deep into the world of air-to-air (A2A) heat pump systems for domestic properties. We were incredibly fortunate to be joined by two distinguished guests: Es Tresidder, a consultant specialising in Passivhaus design and low-carbon building design optimisation, and Michael Cosham, a seasoned HVAC engineer with 47 years of invaluable experience.

Our conversation began by exploring air-to-air systems in general, including Michael's personal experience building an A2A system for his first home on Canvey Island. Es then shared insights into the A2A system installed in his own highly efficient home, providing a real-world perspective on their performance.

We thoroughly discussed the numerous advantages of A2A systems in domestic properties, highlighting their efficiency and effectiveness. We also touched upon some perceived disadvantages, but as our conversation unfolded, it became clear that many of these concerns, such as fan speeds, comfort, noise, and even dry skin issues, may be simple to resolve with proper system setup and design. Indeed, with the right configuration, these issues may not even exist. 

For more on this, and avoiding potential pitfalls, Es has provided these insightful articles:

• About overheating in low-energy buildings: https://www.highlandpassive.com/do-low-energy-buildings-have-an-overheating-problem/
• Understanding thermal comfort: https://www.highlandpassive.com/why-do-i-feel-chilly/

A key takeaway from this episode was the remarkably low cost of A2A heat pumps, making them an increasingly attractive and accessible option for homeowners looking to embrace sustainable heating solutions.

Join us for a truly enlightening discussion that challenges preconceptions and sheds light on the true potential of air-to-air heat pump technology.
