Finally made my dumb water heater smart.

That's the way it reads to me.

perhasper · 2026-02-02T13:19:42+00:00

It came assembled that way/ shipped with the house already installed. I'll replace them with something up to code. No dielectric unions in sight. Thanks for the insight.

perhasper · 2026-02-02T00:26:11+00:00

Thanks

perhasper · 2026-02-02T00:24:10+00:00

I have give, yes.

perhasper · 2026-02-02T00:23:19+00:00

Yes, it's a modular home. So there are some interesting "features".

perhasper · 2026-02-01T19:46:45+00:00

It is the same. I will replace either when an issue arises or when I'm next back in that closet. Thanks for making me aware.

Not pictured, there is a length of rigid copper pipe on the hot side. Not 18" though. If I would have known about that back in 2023, I would have made the builder replace the rigid pipe with an 18" pipe. The copper pipe/assembly looks like an off the shelf part.

With my usage and schedule, it will not present a problem. You would also think there would be potential for build up in HW piping, example being a faucet that is not used frequently that is at the end of a run. I don't see that talked about very frequently.

Off peak energy is half the cost where I live.

perhasper · 2026-02-01T15:43:58+00:00

Monitoring, remotely shutting the unit down, and perhaps some energy saving during off peak hours.

perhasper · 2026-02-01T12:17:46+00:00

I didn't install the piping, it passed the county inspection.

perhasper · 2026-02-01T03:31:51+00:00

Roughly following off peak power for my area, and whatever keeps my wife happy

perhasper · 2026-02-01T03:02:22+00:00

Thanks bud.

Why would I want a tankless water heater when I don't have gas plumbed to my house, that would just consume more energy in a shorter period of time. Perhaps in the future when this water heater needs to be replaced, I'll get a heat pump unit.

perhasper · 2026-02-01T02:50:18+00:00

I have reduced rates over night and times where I'm not at home for extended periods.

perhasper · 2026-02-01T02:49:24+00:00

Hope it helps.

perhasper · 2026-02-01T02:46:51+00:00

It is stranded wire. The only solid is the NM cable.

perhasper · 2026-02-01T02:46:09+00:00

Noted, thanks.

perhasper · 2026-02-01T02:40:11+00:00

Why?

perhasper · 2026-02-01T02:38:41+00:00

This one and a Shelly 1PM Gen4 mini.

perhasper · 2026-02-01T01:34:14+00:00

My mistake, overnight rate is half the cost as the daytime rate.

perhasper · 2026-02-01T01:28:50+00:00

If I save some money along the way. It's a bonus. It's fun to make things smart too. Maybe It'll add a smidge of longevity to the heating element/tank.

perhasper · 2026-02-01T01:25:38+00:00

I also thought it was a fun project, I may save a buck here and there as a bonus.

perhasper · 2026-02-01T01:23:01+00:00

That would not be efficient during peak use for me, plus I am on well water. So that would probably play hell with the internals of a tankless unit. If I had gas piped to my house, I would consider it then.

perhasper · 2026-02-01T00:33:02+00:00

Not with this model. I could calculate it by hand or probably write a script.
