If I go 30 amp, I also need to run new conduit the same distance, whereas I can easily fit three more 14 gauge in some 1/2” conduit that runs nearby. By going with the 15 amp version, that’ll let me use 14 gauge wire instead of 8, and I’m going about 35 feet, maybe even more like 40 or 45 as I haven’t precisely measured it yet, and with wire prices, that comes out to $60 in savings just on wire. I don’t want to use the two the Sense is on until I get an electric car, somewhere between next year and 20 years from now. The issue is that I only have one unused breaker right now. So if you’re running a dedicated circuit already, I’d still recommend going with the 220v/30 amp versions.Įverything I’ve been reading says dedicated circuit, and I certainly agree with that. I expect for a 110v/15amp water heater, you’d still need it on a dedicated circuit. Here’s hoping that product line can make its way around the states. I just thought I’d share that Rheem news as it was only announced 3 weeks ago. Hopefully this means that more people can make the easier transition away from natural gas while also being able to glean exacting usage from their heat pump water heater. I’m guessing that means California changed their electric and/or plumbing code to allow for a plug-in replacement model, but that seems to confirm that there’s no safety reason why a 120v heat pump water heater couldn’t be plugged in. RHEEM® INTRODUCES 120 VOLT PROTERRA® PLUG-IN HEAT PUMP WATER HEATERS That press release specifically mentions California multiple times. However, Rheem now makes an official plug-in 15 amp, 50 gallon, heat pump water heater. Of course there’s the argument to be made that an electric double oven doesn’t get swapped out often and that both plugs-in and isn’t wired to its own cutoff switch, but I don’t think one can argue with the NEC. Generally, codes seem to say that since water heaters are an appliance that doesn’t get swapped out often, you hard wire it in to a shut off switch. I’ve been reading up on electric codes, and while it sounds like some southern states like Texas and Florida used to have plug-in water heaters, that is no longer a thing. Since it’s 15 amp, it could even go on a smart plug. Richmond has a 50 gallon, 15amp model, that would be a fairly 1-for-1 swap to our 50 gallon nat gas model. On a form for certain energy reheated, it looks like Rheem makes the Richmond line since Menards doesn’t carry many brand names, like Rheem, much at all. We used to vent, and waste the heat, from our natural gas dryer to outside, and now we reuse our heat and just pump some water down the drain.Īnyways, Menards’ (a big box hardware store in the Midwest) brand of water heaters is Richmond. 2WiFi broadband internet connection required.I’ve been researching heat pump water heaters again after the success of getting a heat pump dryer.
