What to do? 2 50-gal hybrids or 1 80-gal electric water heater
Comments (14)Zone4 - you might not be happy but disclosure wouldn't apply here. There is no code requirement that applies (that I know of) and so there is no breach. It would seem that installing LP for that purpose alone seems a little extreme. One option - which has cheaper run cost and install than the LP tankless option - run a recirc loop from that bathroom to the tank. Have it on a switch. You turn on the switch and the line fills with hot water. The pump is $200, electric should be $200 and extra plumbing is $100. You won't waste water and as long as you shut it off, you won't waste electricity to heat the water. My $100 charges of course are guesses and the plumbing in the slab might be more. The $200 electric is what it would cost me in NC. You can of course put the kitchen sink on the same loop and install a switch at that location too. Recirc loops are done all the time but where you need to be careful is the energy loses because they are usually left on nearly all the time. By having them on-demand with switches, you counter most of those losses. To help with some of this, I would definitely insulate the slab plumbing lines. Another option would be to do solar for the hot water and use a 80 gallon tank. If the incentives are there, solar can be reasonable. I paid less than $2000 all in which is about the cost of your 2 50 gallon heat pumps....See MoreQuestions about hybrid electric water heaters + electric tankless
Comments (1)Electric tankless will require an upgrade as well ... on the electric circuit. A typical electric tank takes a 25 to 30 amp circuit. Electric tankless can be high as 120 amps depending on the needed capacity. Capacity in tankless terms means the heating power required to raise the desired rate of water flow (gallons per minute) from the starting point (lowest tap-water temp experienced during the winter season) to the desired output temperature (typically at least 120ðF for a kitchen with a dishwasher). If your house has a large-enough existing electric drop from the pole, then you'd only have to run a larger circuit from the breaker box. Otherwise you'd also have to upgrade the service drop from the pole....See MoreHybrid Heat Pump Water Heater + Point of Use (all electric)

Comments (13)Update-My home warranty company has dispatched it to a new plumbing company. Since I am technically partially disputing the first plumber’s findings (that it was caused by an electrical surge) a different plumber has to take a look and see if he agrees with the first plumber or if he says it needs to be replaced but not because of an electrical surge. I currently have the power off to the unit because I don’t want it to overheat and deal with whatever happens when that happens. My question is what do I do now? If I leave the breaker flipped off the plumber will report that the breaker was flipped so that is why it’s not working. It will start to heat up after he flips it back on and he’ll say it is fixed. I called the new plumbing company and have an appointment scheduled for Tuesday 7am-noon. I gave them the history of what is happening and they said the tech will call me 30 minutes before he gets to my place and that I should turn the breaker on then. It started the wind “shhhhh” sound at 1:30 am this morning, 12 hours after the electrician left. If I turn the breaker on 30 minutes before the plumber gets here he’ll likely see that there is hot water so it’s technically working but I have no idea if it will be shhhing/overheating by then. I did video the sound I heard this morning. In the video you can hear it (it was louder in person) and it shows that I flipped the breaker and the sound stops. I can't upload that here though. I’ve also asked the electrician for his report showing that there wasn’t an electrical surge. Any ideas? The lowest quote I've got so far was the $1,700. The company that came out through Home Depot said that to give me quote he would need someone to come out and cut the drywall to see how much of a leaking pipe needs to be replaced. The other plumber that gave me a quote was $2,300+. I'll keep looking for estimates and try Lowes. The back and forth is very frustrating. However I'm currently working from home. Welcoming them and repeating the situation to the next person is starting to feel like a routine....See Morejakethewonderdog
