Octopus Energy Heat Pumps Explained | TJ Root

In this episode of Energy Unwrapped, I’m joined by TJ Root from Octopus Energy to walk through the full journey of getting a heat pump, from the first online quote through to survey, design and installation.

We talk about the Octopus Cosy heat pump, why it looks the way it does, how it is installed and what really matters when it comes to heat loss, radiator sizing and system design. There is also a good discussion around common concerns like noise, siting and R290 refrigerant.

A big part of this episode is about getting the basics right. We get into why heat loss figures can vary, why gas usage is not always a reliable guide, and why slightly undersizing a heat pump can be a bigger risk than many people realise.

If you are thinking about a heat pump, or just want to understand how the process actually works in a real UK home, this is a really useful one.
