As in, tankless water heater! The house originally had a tank water heater shoved in front of the electric panel in the very tiny utility room. I remember the back door would hit it when fully opened, and I don’t think I could even open the electric panel completely until the water heater was carried out. And that alone proved interesting – my brother-in-law leaned the top toward himself (it was completely drained), and I went to pick it up from the bottom. Light weight, yes, and then my hand broke through the tank just from carrying it because the metal was so rusted. That’s probably a big part of why the laundry room wood floor is so discolored and sunken along that wall. Basically, if I wanted a standard washer and dryer in this room, there was no space for a conventional water heater.
I had already cleared the trash out when I took these before photos of the entire house, but you can see the rusted ring on the floor where the old tank sat. And leaked. Slowly. For a long time, or so the floor boards would say.
Well, not having a water heater isn’t such a big deal since I’m not living there yet. But once I got the plumbing finished and the kitchen sink hooked up, I was itching to get the tub cleaned and then also the leftover fridge which is pretty grimy inside and out. And technically I didn’t need hot water to do those things, but I wanted it. Cleaning is gross with cold water, but somehow not so gross when you have hot water.
After reading what must have been hundreds of online review of electric tankless water heaters, I decided upon the ecoSmart brand. The reviews were almost all positive from homeowners and even businesses that had purchased and used this brand. Any negative reviews were either customers who purchased too small of heating capacity for their home, or people who tried to do a DIY installation before reading the instruction manual and damaged the electrical during the install. (And then there were reviews where they had really bad grammar and couldn’t form whole sentences, which makes me think they also fall into the 2nd category. Word to the wise, if you sound like a backwoods redneck when writing a product review, any half intelligent person will probably disregard your comments as “operator error”.)
I decided upon the ecoSmart 27, which means 27 KW of heating capacity. It’s actually the largest residential unit they sell and should be more than adequate for my size of house with just 1 bathroom. But our winter this last year was record breaking cold and for weeks at a time, so I felt very comfortable steppin’ it up to the larger heater. As Tim -The Tool Man- Taylor would say, “More Power!”
Here’s how the unit looks installed on the wall. I was able to order the water heater from my local Ace Hardware store (shop local is kind of my mantra – it goes with the job), and they had just 1 in stock at their warehouse. Ignore that the drywall isn’t finished on this wall, but I was in a hurry to get the water heater installed. It’s rather high on the wall, just about 2 feet below the 9′ ceiling. But because it’s opposite of a west-facing window, I wanted to make sure it wouldn’t be in direct sunlight and have that effect the multiple thermostats which control the heating elements. As the photo above shows, I used flexible copper water heater connections to transition into the wall, and then it transitions back into 3/4″ PEX. That was the round 2 decision.
I first tried fancy PEX fittings to make the 90 degree bend out of the wall, and then a PEX to threaded connection to join to the water heater. The only problem was that the threaded PEX fitting didn’t have a rubber seal inside, and the small garden hose seals you can purchase wasn’t enough to keep it from leaking. So round 1 resulted in a very wet floor. And wet me. And wet Dennis – unable to connect the electrical, helped me decide that I needed to find another type of connection. He found it funny. At the time, I did not. But looking back, if that was the worst leak I ever have while I own this house then I’m not doing so bad after all.
The photo above also shows the water heater in “sleep mode.” It probably has a more technical name (off?), but the LED screen is blank when the unit is a rest. The screen doesn’t light up unless I adjust the temperature wheel or until I turn on a faucet to use the hot water.
Then it’s lights on, displaying the hot water temperature setting. That’s why this unit is supposed to be such a dramatic difference in energy usage compared to a traditional tank water heater – it only uses electricity when I am actually using hot water. Unlike a tank, which uses electricity on and off constantly to keep the entire tank of water a consistent temperature. And even though it has a strong heating capacity, it knows how much water I am using and how cold the incoming water is, so it uses the minimum amount of electricity needed to reach a constant flowing hot temperature. I haven’t tested it with a thermometer yet, but I believe the numbers. 125 degrees feels normal to me for activities like washing dishes and showering. But for scrubbing the bathtub, I was filling gallon containers and pouring out a little at a time, so I had it turned up to 128 in the photo above.
To sum it up, use the correct parts and pieces when installing a water heater to avoid saying bad words and having a wet floor. And wet clothes. And wet electrician helper. It seems to be working great so far, the water is fast to heat up to full temperature, and it stays steady for as long as the water is running. I’m eager to see how it will do (and how much faster the electric meter will spin) when I have a shower head, washing machine, and kitchen sink all pulling hot water at one time. But I’m a little ways off yet from being able to test it that way.
