    • Four upsides and a downside
Size: 29 (kW) Style: Tempra Plus
For five years I've lived in this home with a 75 gallon gas hot water heater. It was in the house when I moved in and to be honest I've never had any complaints. Though it worked fine I decided to change out and because we are going solar roof next year I wanted to go electric. For the same reason we had gone gas furnace to electric heat pump for heating. I needed to decide whether to go electric tankless or electric heat-pump water heater. I went with this unit, the 29kw size. There are only two of us in the house so it seemed more prudent. We have several EVs and the largest tankless along with EV charging would be a fairly large load even for 200 amp service. First the upsides: 1. Unlimited hot water. Both of us can take showers at the same time. The only issue that two of us can have is if both of us want showers while the first cycle of the clothes washing machine is running. Minor limitation. Timing is everything. 2. Absolutely using no power when we aren't using water. We can go away for a month, walk in the door and take a shower and get instant hot water. 3. Accurate temperature control. We have two presets and one has been set for filling the soaking tub. Just press the button and then run pure hot water to fill the tub. The tub gets filled to perfection without figuring out the calculus of the mixing valve which changes depending on the temperature of the water coming into the house. This is a great feature that nobody told me about. 4. The house was originally built with what I consider a shortcoming. The hot water heater was located next to the furnace so it could use the same flue and gas connection. This is fine for ease of install but the hot water heater is on the other side of the house from where the hot water is most often used. Running the shower in the master bath or the sink in the kitchen required a full minute of water running to get hot water. We now installed the tankless beneath the kitchen where we use the water. No flue is required. This unit goes anywhere. Now we have hot water in a hurry where we use it. The downside. I once had a power failure that lasted several days. The water heater was the same as I replaced - used no electricity and vented naturally through a flue. There is something nice about a hot shower during a power failure. That will no longer an option. But then, I haven't lost power in five years. The only upside of the tankless heat-pump water heater would have been its (limited) supply of hot water during a power failure and its natural de-humidification feature. With everything considered, we went tankless. Just a tip, the most often warning I've heard with tankless is impurities in the water that can collect. To reduce this problem we installed a whole-house water filtration system after the water-softener and ahead of the heater. Note that I only gave tech support three stars - that is because I didn't need them so never found out about their quality. I did need power though and didn't have the required six circuit breakers that the unit required. I installed a 125 amp sub panel dedicated to the water heater. The unit has been flawless. It just works. ... show more

    • Why did we wait this long? With 1 Year Update!
Size: 29 (kW) Style: Tempra Plus

Been hobbling along with a 38-gallon tank for a family of 6 in a two bathroom house for close to 10 years. This is up there with one of the best appliance purchases we've ever made. For the first time ever could fill the bath up. The first time we could get everyone a bath/shower within an hour - had to wait 20-45 minutes for the tank heater to "reheat". Freed up a whole closet full of space! Had electrician expand into a separate sub-panel for this. No dimming when active and cut-offs for each circuit next to the unit. Fairly easy DIY install. Had old unit out and new in over a few hours. The buttons on the unit for the saved settings and information weren't working out of the box, but only because it had separated a bit - snapped the circuit board right back into place and all good. Quality seems very high. We are in south Texas, so no worries about ever getting the water hot enough. Settled around 120 - inlet temp never drops below 60. Weird not thinking about not doing dishes before (or during) someone's shower because you'd use all the hot water... guess I get use to worrying less. :) Update After 1 Year: Including picture of the units calculated savings - $153; not too shabby, thought have to admin, this device makes it a bit easier to use more hot water. Rarely a week goes by without still have a large amount of appreciation for this appliances. Still, hands down, best appliance upgrade to our home. No issues and I'm keeping up with descaling (with vinegar) once a year. ... show more

    • Almost perfect
Size: 29 (kW) Style: Tempra Plus
there is no natural gas on our block and so we decided to go full electric tankless, hoping it would be enough for our 3 bedroom, 2.5 bathroom home. We love it when it comes to showers, appliances, kitchen and bathroom faucets. Life is uninterrupted on those fronts and we’re very happy with the unit. The two problems we’ve encountered are that our bathtub pressure went down quite a bit and with 2 messy kids we thought that was going to be a problem. We learned that if you turn the max temp down to 110 (we had it set to 125 at first) then there is more capacity at a very hot and comfortable temp. That helped split the difference on bathtub pressure. The other is that if you are running a bath, you will see a big decrease in pressure in the other hot water faucets in the house. So the adjustment was to not try to shower or do dishes while running a bath which is no big deal. And we don’t take two showers in different bathrooms at the same time. Otherwise, the unit is incredible. We are saving money on electricity each month since a tank has to stay hot 24/7 while this unit is only on when you turn on a hot water faucet or run an appliance. And there is great pressure and heat for all of our daily tasks under normal circumstances. Ultimately, the shower is great and we can do dishes and run appliances without a hitch. I would recommend purchasing this unit if you are ready for a minor quality of life adjustment for the energy and space benefits. ... show more
