Finally, someone took his priceless time to explain these themes in a simple language to an apprentice like me. It was really much appreciated

You're welcome. Thanks.

Interesting Mike. thinking at its Finest...

[@johnnybgoode5598]

Can you do some vids on troubleshooting combi's and heat only wall hungs? Not much on the net about them. Anything would help. Love ur vids. Very detailed and informative. Thanks for your work!

[@JerseyMikeHVAC]

I'll certainly try. Thanks!

[@Jason-qe4tp]

Hey Mike, I need help with zone damper troubleshooting and conversion guns troubleshooting and repairs....If you could help me out, I would greatly appreciate it. You explain things great and I retain it easily. Thanks for that seriously

[@JerseyMikeHVAC]

Conversion guns?

[@Jason-qe4tp]

@JerseyMikeHVAC Riello and Carlin oil to gas conversion gun. And i saw video on zone dampers too, it helped me out too, but still need help on some of the older ones. Thanks for responding your the man!

[@brandoncoffee8044]

Is this method used only on larger homes with a lot of piping, or can it be used on smaller houses with very little piping as well??

[@JerseyMikeHVAC]

It's always on larger, multi-zone systems, but not exclusive to it. This design can be applied to any circumstance and often is, as the alternative requires very detailed design skills that are not so common.

[@mattkaramccarthy677]

@@JerseyMikeHVAC perfect answer right there. I know few contractors that could actually compute the correct pressure drops and pipe size for a direct flow system. Even explaining residual head for the internal pump is a struggle most days.

[@jdogar1]

i worked as a plant operator for about 10 years. I used to get thoughts like this while plant is running itself...

[@JerseyMikeHVAC]

Power plant? I used to run a coal fired supercritical and later a combined cycle. Impressive how these things work.

[@jdogar1]

@@JerseyMikeHVAC No at oilsands refinery. At fort mcmurray AB. Also i worked at Data Centres. Are you in from Canada or USA? Yes its is impressive...
