I don't know anything about the hydrokinetic systems used by some homes that are electric (no gas / no oil).
Specifically, I recently saw an ad that a home offers a
"Hydrokenetic system with a humdiifier and 80 gallon H/W heater "
This is somehow supposed to be very efficient. I can't
seem to find anything on the web about this.
1. Does someone know a link that I can use to read about
2. How efficient are these systems, and under what
principle(s) do they work?
3. Miscellaneous comments??
I've heard of Kinetic high efficiency boilers which are gas or oil fired and an indirect tank,but not "hydrokinetic"
Might be something like an electric HW heater hooked up to a hydro air coil. I can't see how this could be any beter then a heat pump. It probably would not work to well in a very cold climate since the elec WH would have trouble getting the water over 120 degrees.
I think you are referring to the Hydrokenetic off peak storage system.
They have some querks.
If that is what you are looking for, let me know and i will tell you about them.
beenthere what is it? How is it used?
Almost the worst idea ever!
Atleast the hydrokenetics.
With the cooperation of the power companies and special meters, these units heat up the water in a steel,(yes steel without a liner) at night. the smallest tank is 400 gal, the largest i work on are 1200. the electric meter has a timer and relay in it, when the relay signals the hydro, it heats the water at night for about half the elec rate that you or i pay, the tanks are sized to hold enough heat, to heat the house the next day without having to use the elements again till the next night. The water heaters also work off the same relay.
CATCH 22, if you use more than x kw during the peak hours, you must pay a higher rate on all your electric.
They tried digital boards, found that airplane radios made the boards boil the water, had to switch them back to anolog.
The company went out of buissness, now it is very hard to get parts.
Can you tell i don't like them?
It is a great idea on paper, but not in reality, it is hard for most people to stay within the restrainst that the meter puts on them.
The off peak time period starts at about 5 pm, and runs till 7 am.
Sounds like you installed a few.
Only helped to install a couple, (I knew after the second one it was a bad idea) but work on way too many of them, they have been trouble from day one.
OH yea, these are non pressurized vessels.
These units are hooked up in 20 different configurations, with heatpumps, or cast rads, or hydro coils, or with oil or gas back up, and alot of other ways.
They are a wiring nightmare.
So if anyone is buying a house with a hydrokenetic, get ready to either pay big elec bills, big repair bills, or change it out.
I just had a call today for one that sprung a small leak.
I got it fixed, but who knows when it will leak at another area.
Oh, did i mention that the #$#@#$# steel tanks are real heavy.
At least if it were a good hydro coil config in ductwork, it shouldn't be too hard to just put in an oil/propane/nat gas boiler to replace the crap water tank. If you can get the house at a good price and the fuels can be brought in or nat gas is already there, it should be an easy upgrade.
You should also find out what gives you the best BTU per $.
Thanks for everyone's feedback.
I did some research with the power company regarding some of the statements made by 'beenthere'
There is no limit of KW hour usage. I may use all the power I need all any time with no penalty, under the following conditions:
1. peak hours are from 7am-5pm, 8am-6pm or 9am-7pm; customer choice.
2. peak rates are slightly more than 3x the off-peak rates.
3. I was quoted the following:
peak KWH off-peak KWH
DIST. 3.053 0.993
GEN. 8.957 2.542
TRANS. 2.931 0.954
4. Fixed monthly cost of $12.47/month
5. These rates are for the Pennsylvania Power and Light (PPL) company.
I forgot to ask what is the flat electric rate. I wonder how the normal flat rate measures up to the peak and off-peak rates above.
Thanks again to all.
Hmmm. it must be something for new customers. PP&L uses a normally closed relay in their meters to contol the hydro.
GPU uses normally open.
Many of the units I service are in the PP&L area.
The rates they quoted you are far less than the last 4 customers I was at. They were paying just over .04 KWH.
But, as long as they garranty it to you, go for it.
The original rate was only garrantied for 10 years.
Also check with the previous home owner if it has been sevice every year. Its a steel tank, does it have rust inhibitor in it?
Also did they explain to you, that the water heater won't charge during peak hours, unless you use the over ride.
Our customers that do this are the ones that complain the most.
But, good luck with your system.
PS: We're one of the few companies that still have, and can (or know how to)get certain parts for them yet.

I just reread your post.
There not giving you the normal discount on your on peak hours.
The original set up was a lower rate all day as long as you didn't go ove x KWH during on peak hours.
BUt, your still getting it for your off peak, so the bill shouldn't be too high.
So how is the hydro doing for you?
