Posted by: @jamespaFair enough, we need diagrams for the masterclass otherwise confusion will reign!
I’m working on some easy to follow and understand diagrams that we’ll show in the video.

And on that note, our inaugural episode of Renewable Heating Hub Homeowners’ Q&A is out, and we discuss buffer tanks as promised. 🤔
Our panel features Brendon Uys (@heacol) from Net Zero British Gas, Simon Murray (@simon-m) of Optimus Heating and James Clark from Elite Services Group.
This is our episode, so there were some sound teething issues that we hopefully won't have in future content.

All 3 drawings are hydraulically separated and are all buffer tanks. The third does not show a pump in the heat pump, which there has to be one, or water will not flow through it. You can see the pumps on the other 2 drawings.
Our first episode of Homeowners' Q&A has been generally well-received – though it did ruffle some feathers among those with a vested interest in buffer tanks!
Building on this momentum, we’ve lined up some fantastic panels featuring top industry experts to discuss crucial topics related to domestic heat pumps. But to ensure these discussions stay balanced, relatable and truly helpful, we’re looking to bring more homeowners into the conversation.
If you’ve faced issues or have concerns about your heat pump system, we want to hear from you. This is your chance to be part of an open, honest dialogue that could help thousands of other homeowners just like you.
Interested in being on one of our panels? Drop me a DM! We’ve got some genuinely exciting topics lined up, and we’d love to have you join us.
Just a heads-up: there are a few tech requirements. You’ll need a decent mic, headphones (to prevent feedback), and a well-lit space for recording.
Looking forward to hearing from you!
