Thanks for sharing Andrew. When are you planning to have ur own plumbing and heating courses. 😁 Such knowledge and expertise you have should be passed on to the generations.
The heat geek course awakening is based on the classes I taught for ecotechnicians. It's an online course and has further learning from Adam Chapman AKA Heat geek. It's a vital course for all heating engineers imo.
@@andrewmillwardwatford9410 thanks for reply. Just got a quick question (apologies for Sunday ev post) If u have a boiler change where the upstairs is two pipe system while the downstairs is a one pipe system with massive cast iron old rads. Do u think a CCT at the boiler then run a tee brach for upstairs and downstairs Or a boiler flow to 2 pipe circuit and its return cct , then that return to be the flow for the one pipe system and back to boiler ? Would appreciate any ideas. Knowing customer wants the very very minimum cost wise option
Good vid , should the expansion vessel on the secondary system be tee'd In before both pumps ? That's what I thought obviously wrong just want to know why pls
@@richardcorrigan6940 any contamination present in an existing heating system is prevented from entering the boiler by the addition of a plate heat exchanger
@andrewmillwardwatford9410 Think I've got it now Andrew.So the boiler will have its own mini circuit through the Phe and then will transfer through to the primary heating circuit with approx delta t of 4°c (judging by your other video).Thus ensuring that anything within the boiler circuit can only have come from the boiler.Thank you for the insight.
Looks a very nice install indeed.😀👍

Hi
Do you require a separate flow sensor when using a plate? Or can you run the system without if the pumps run when a call for heat or demand?

It is piped up before both pumps. Look closely and think about its position. Remember this is hot water priority so only one pump runs at one time.
Cheers thanks for reply 👍
Hi Andrew, I was a member on your Facebook group heating system design but some how can't find it now in my search bar any ideas why? Thank you
Forgive my stupidity Andrew,but what is the advantage of or purpose of installing a plate hex?
To protect the boier from contamination.
@@andrewmillwardwatford9410 how so?Oxidisation or lime?
