Koven water heater

I currently have a Koven water heater and had seen some previous conversations on some of these older units. I am not sure of its date but amazed that it works so well when I moved in here. I'm sure it spins the electric meter but wondered if anyone has any input on these. Thanks

Electric is electric, there really is no significant difference in efficiency.
@Larry Weingarten can probably give some insight."If you can't explain it simply, you don't understand it well enough"

Hi, I've only heard the name and seen other, similar units. If you could give us a close up of the name tag at the bottom, and another shot of the top of the tank, I might be of some use. Also, that pipe sticking out at the bottom left... Is that the drain valve? More fun could be had by sliding out the panel in front so we could see what type of elements and thermostats it has. (of course, turn off power first) Looking at it with an IR camera could be interesting too!

Im wonderig if it is an early version of the Vaughn/ Sepco stonelined (portland cement) water heater0

Thanks for the input, and yes it is stone lined according to plate on other side.I will send pic of data plate tomorrow, thanks0

Hi, Found this brochure: https://www.ebluejay.com/ads/item/5666672 It's a start. So, based on what I see in the brochure, two questions come up. Does the tank have a relief valve? Does it have an anode that MIGHT need replacing? (Shouldn't, but trying to be thorough.) I'm impressed that it has 3" of insulation!

My back aches just looking at it.Retired and loving it.0

Thanks Larry for link thats neat. To clarify this unit works fine I was just curious on the year of this unit it amazes me how it has held up, they just don't make things to last like this anymore. I've added pic of data plate.0

Wonder how many of these are still in use? Lol0

Hi, It's just a guess, but the serial number starts with 1152, so it could have been made in November , 1952. No spring chicken! Still, having a relief valve isn't a bad idea. It became code across the US in the 1960s because heaters blowing up was a fairly common occurrence. Your heater would be roughly the equivalent of four sticks of dynamite.

Thanks Larry, not sure I like the sound of that lol. This could be pressure valve? I hope so and that it works. Guess I should update this unit for safety purposes. Works really well but don't need any loud surprises.0

I have had this unit off before for couple days and water was still warm when turned back on, must be insulated pretty well.0

Hi, I’m not suggesting that you replace the heater.. keep it! I see a pressure relief at the bottom, but what’s needed is temperature relief as well. You could put a T right at the hot outlet so a T&P could be screwed in. That gets the probe into the tank. Then continue plumbing from the side outlet of the T to hot. This way you can have a safe and classic heater!

kcopp said:I dont think you can get a t&p valve in that... they integrate a dip tube into the outlet. Code says it need to be in the top 6" of the tank. I would replace it. If that ever overheats it would be a mess.
Why would there be a dip tube? And on the outlet?Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

Dip tube is not the best term.... As they say in the literature a "heat trap" . Vaughn Sepco did/ does the same thing. they come out w a 90 off the top and run it down to a drop ear 90 for the outlet. the hot outlet does not go into the tank. A T&P would not fit.

The phillips screws would be a bit unusual for the 50s.0

Hi @TimK865 , I think I'd start by removing the top to verify/see if there is a heat trap. If so, and if it's threaded, adding a T at the top of the tank would give a good spot for the T&P. If you can take a picture with the top off, it would be useful to see!
