When I contemplated having a podcast, this was the first idea I had for busting some myths about owning a heat pump.

It's not your usual discussion on efficiency. Inspired by the legendary Murray Walker, this looks at a dilemma faced by many every day and how our heat pump not only was up to the task in hand, but used less energy too.

NB - our hot water tank is a 320 litre one, so the pump is doing a bit more than I estimated in the podcast.

Our heat pump is a Visessman Vitocal not Vitodens! Though I did get the coefficient of performance (COP), aka seasonal performance factor, right: 4.2 was our value last year and the year before.

In this episode, I share how the right insulation in the right places can help you stay cool during the summer and warm during the winter.

I hear many broadcasters complain that UK homes are built for retaining heat and not keeping cool during the summer. But actually, it we think of insulation as allowing us to maintain a comfortable living temperature, insulating your home could give you that benefit.

Following on from this article on my blog, we examine what has been working for us, what we're thinking of doing next, and what might be worth looking at for your home!

If you have any thoughts about this piece or subjects you'd like covered, please leave a comment below. It's not all about creating shaded spaces this summer!

How have we managed to live 10 weeks off grid while high heat has meant our solar production has been a little lower in June than it was last year? Why would we want to do such a thing?

Should we have been braver doing this?

This draws on the figures shown in article Living off the Grid and a little more besides.
