I had been looking forward to buying a tankless instant water heater before I had even moved out of mom’s place.
Unfortunately, each place I lived had a perfectly good water heater already.
Besides, my 6 gallon tank was no where near as wasteful as the 80 gallon monstrosities in regular homes.
Then, last week, the tank began to leak.
I had my excuse.
I discovered that there is only one company which makes instant
water heaters specifically for RVs. Having no competition, they price
it around 5 times higher than others. I decided to go with a small house/cabin unit instead. I found the least expensive one online; it arrived quickly. It spent a
week in the box as I didn’t have the time to install it. When I finally
did, turned out I hadn’t considered the vent when I measured, and it
wouldn’t fit. Damn.
I sent an email asking about exchanging it for a smaller unit. Within 15 minutes they called me by phone. They said they couldn’t accept a return since I had already begun installing it. I was ready to just sell it on craiglist and buy the smaller one,
accepting that it was my own stupidity to begin installation without
measuring, plus the website did clearly say the original box was needed
for returns, which I had already recycled.
And then, without being
asked, the guy offers me a 15% discount on the new smaller one I was
going to have to purchase. He emailed a custom order form, with a price
even slightly lower than what he had just offered over the phone.
Wow. Beyond expectations. The only business I know with customer service like that is, well… my own! If you ever need a water heater, seriously, this is the place to buy: And no, I don’t get anything for recommending them. Come on. You know me better than that, don’t you?
So, now it’ll be a few days before I get the smaller unit and I can install it properly. In the meantime, I was sick of being without hot water so I
jerry-rigged the one I have into place. Between some parts from my old
water heater, a flexible metal pipe I found on the street, a piece of
wood 2×4, and a generous amount of tape, I have hooked up the water
heater. It leaks a little where its attached to random-found-pipe, so I
have to put a bowl under it while the water’s running.
But as far as the heater itself goes… you turn on the faucet, and within a second, the fire is blazing. You turn it off, poof, like that, its out.
It is much hotter than my old one ever was. The total flow rate is higher too – its like taking a shower in a real house!!
I had gotten used to low flow showers. I had forgotten how pleasant being drenched with warm water while naked can be.
And it NEVER RUNS OUT! Well, I guess once my propane tanks ran out. In a few months.
As I was taking my 30 min long shower, I thought about how I am
actually saving energy overall, compared to before. While before I was
limited in the length of a shower when the hot ran out, the tank also
kept the water hot 24hours a day, while I was a sleep, while I was at
The biggest unit they sell should be enough for a one bath house.
For a really big house, if everyone wants to shower at once, you can
double the capacity by linking two of them in series.
Or using with
an existing tank heater, you could leave the tank at its minimum and
have the output of the tank go into the instant, which would then raise
the temp the rest of the way only when you turn on the hot faucet. Way more energy efficient, endless hot water.
While an 80-gallon tank heater is anywhere from $600 to over $1000, a 4GPM tankless is only $325. Why tank heaters even still exist, I really don’t get. Akin to American’s rejection of the metric system and Dvorak I suppose. Well, at least you know.
