"This cylinder is really great"
"It's custom manufactured, so I could specify exactly where I wanted temperature pockets to be for the sensors... Newark are really great to work with"

I've finally finished editing the video of my heat pump installation, there's now some cold weather monitoring data to talk about, TLDR It's working very well, 50% cost saving compared to gas 😃 youtu.be/Tz0W9xCBxS0
