[king of pipes]

I believe this week he’s changing a few things so if it doesn’t resolve it self by Friday shoot me a pm 🙂

Ok Shaun will do bud have a good week . Regards kop

Looks good and tidy pipework! I was crap at pipework, probably why I don't install 😂

I understand that there will be courses available from the manufacturer this year, I have suggested we advertise the course on PF . Chking

One I visited last year burnt out and had to be replaced !

Any news on training @centralheatking ?

I've recently found out I have a HIU (heat interface unit) in my new build flat. I've been searching the web for info on how they work, but none of them answer my main question - does HIU work by providing heated water direct from a central plant into my flat, or is the heat generated by it used to heat the mains water into my flat?

I don't really understand what the mechanism is.

 

[WC1]

I believe it's essentially a heat exchanger. Communal hot water is used to heat domestic hot water.

I miss doing commercial work, I remember the first boiler that I serviced by suiting up and walking into with a broom to clean the chamber and circulating pumps that you lift into place with an engine hoist - proper work!

I'm just curious really. I did do a quick calculation based on 1500 apartments with the same heat loss and DHW requirements, plus a rough loss through pipework and it was like you say megawatts. I did have a quick Google on size of pipes required to carry this power but wasnt very successful. Like I said my experience is only on domestic properties, I would love to experience larger systems and definitely want to gain experience with commercial and industrial oil fired appliances. I'm not gas trained, oil is all we ever did.

they break it down fairly well here - full list of HIUs available
