vaillant ecotec inlet pressure

[stevetheplumber]

Well keep in mind that Vaillant is not a native manufacturer. In germany when you do your pipe sizing you calculate a pressure gain for every meter of height the pipe is rising. As NG is obviously lighter than air.
Which means every 25m height difference you gain 1 mbar of pressure.

My top reading at a (NG) meter yet is 41mbar. And it was only at first floor 😉.

Never! I instantly tell the customer the truth about the installer oversizing the pipe and causing that way a high IP 😉.
