True, that'll be down to the presentation giver. But first two show hydraulic separation, the 3rd is not hydraulically separated.

Fair 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.

@jamespa here are some easier to follow diagrams (I hope).

Classic 4-pipe buffer

3 pipe buffer

Volumiser

System Separator

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.

@editor That was really interesting and helpful.

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!

We're looking for a homeowner who has recently faced challenges with a heat loss calculation or heat pump sizing to join us on the next Homeowners' Q&A podcast. You'll have the chance to share your experience and get advice and answers directly from our expert panel.

We’re looking for a homeowner to join us on Friday, Oct 11 at 10:30 for our General Heat Pump Q&A episode. We’re particularly keen to hear from someone who’s had their heat pump for 2–3 years and has faced several teething issues.

The panel will feature two heat pump experts, and we’d love for you to share your experiences, both the ups and the downs. You’ll also have the chance to weigh in on questions from other heat pump owners, discussing whether you’ve had similar challenges and how you’ve managed them.

Wednesday afternoon, means another podcast episode, and this one's a cracker. Well worth watching:

We’re recording an Ecodan Q&A podcast episode as part of our Homeowners’ Q&A series on Friday, Oct 25 at 10:30 AM, and we’re looking for Ecodan homeowners who would like to join us as guests.

This is your chance to be part of the discussion, share your experiences, and ask Mitsubishi or our experts any questions you have about your system.

If you’re interested, please DM me or email me at editor@renewableheatinghub.co.uk.

Also, if you’d prefer to just have your questions answered without joining the podcast, feel free to send them over via DM or email, and we’ll make sure to get them addressed during the recording.

Looking forward to hearing from you!
