Finding the chase and cutting to it

This is another piece on how air sourced heat pumps (ASHP) work… Oh no, can’t we talk about anything else? Not yet, and bear with me. This is a fundamental thing to consider when trying to get the most out of your pump. But it helps to understand how a heat pump works to get […]

Breaking the 80% Ceiling of current diabetes technology. For decades, the clinical approach to insulin replacement has treated the human body as a predictable, linear machine.

Last week, we looked at the cash return on replacement windows, which, on the face of it looked marginal at best. But of course, we have made other investments over the past twelve years. Easy steps, let’s look at the LED lighting. About a year, just in saved electricity. Initial cost was about £350 for […]

In the East of England, we have an “artic airmass” causing freezing weather. It’s 2°C out there at the moment, and has been as low as -6.5°C in our bit of the world over the past couple of days. So, what is it like living with an air sourced heat pump in this climate? It’s […]

A question was asked after publishing Is there such a thing as breaking even? “Does the carbon cost for windows repay sooner or later than the financial cost?” I am going to find that a difficult question to answer, as we had some substantial building work done to put in a French door and take […]

This is a look at the second half of 2025, and a follow up to Number crunching part 1. The summer saw us pretty much “off grid” apart from backup. Of course, we still have to pay the standing charge, currently a whopping £0.4595 a day, though I know that is better than many companies […]
