  • Agree with this post here. Adding to this thought:

    Outside of initial provisioning/firmware updates. This server should only need to reboot once a month for OS/firmware security updates and maintenance. Maybe less/more depending on your organizations security posture. OP said they’re running VM’s so I don’t understand the concern with the boot time. Once you provision the host you don’t really tinker with any setting unless your adding hardware to updating firmware/os.

    If the boot time is really that big a deal, get a second host and setup replication/vmotion with your VM’s to eliminate the host boot time from affecting your uptime entirely.









  • Things that were built to code in 1986 may no longer be up to code in 2023. When making improvements it is a best practice to bring things up to current codes, but not always a requirement.

    Towns don’t generally send inspectors around to enforce codes unless you’ve done major obvious stuff like add a bathroom. However, if you ever go to sell the house, smaller code violations can come up during an inspection.

    My hot water heater doesn’t have an expansion tank either, but it is on an open connection to the municipal water supply which acts as one. I plan to add a PRV which makes it a closed system and would necessitate an expansion tank. I don’t believe there is any harm in adding an expansion tank to an open system, other than cost.

    For the pressure relief air gap. The 2015 IRC code in New York for example requires that it discharge to an air gap inside the building. You can then drain it outside from there.

    I’m not sure why a drain pan would not fit. They add a negligible amount of height and aren’t much wider in diameter than the heater itself.

    Electrical panel clearance see section E3405.1 workspace clearance. 30" width, 36" depth, 6’5" height. The 30" can start at the edge of the panel if you’ve got the room on the other side. It’s probably fine, but hard to tell from the picture angle.

    By all means, I think you did a great job and there likely won’t be any issue with the installation. These are just observations from a code compliance perspective.



  • Electrical panel clearance may be an issue. Think you need like 30" width clearance which can be off-center to push it up to the panel edge. Looks tight from the picture.

    Add some fire blocking on the wall penetrations if that is going to an interior wall from a garage.

    Is your pex rated to handle the pressure relief valve temperatures and is the inner diameter equal to or larger than the valve opening?

    Is there an air gap on your pressure relief drain? (can’t see where it terminates.

    Might need an expansion tank

    What is the square footage of the space it was installed in? There’s usually a minimum requirements for heat pump units to function properly.

    As others said: drain pan, straps

    Had a nicer formatting post writen but lost it when trying to post during site outage.
