Heat Pump water heaters.

[fl_dude]

Do any one have any links of where I can buy HPWH's from ? You would think here in florida, they would be every where, what with running A/C 24/7. All I hear here is "my electric bill is so high" and here is a good way of helping lower electric usage and no one down here sells them, or so I am finding. Please prove me wrong.

I have spent the whole afternoon searching firstly on google, then yahoo, followed up by MSN, and the 2 links already posted here are the only 2 I can find to. I was looking for them little boxes with a small heat exchanger and a pump inside of them, that you hang on the wall near the condensing unit. I found a make called dynamax to, but no prices. I cant believe we cant buy these things and heat our water for free, guessing the electric companies has bought out all the companies that makes them, to keep up the summer electric bills

It seems once FPL did away with the rebate some years back, they just aren't popular. Go figure!

FPL has recently announce an $150 rebate on hpwater heaters. Regards TB

You mean you have to significantly heat your water in the summer?

A luke warm shower is Hot enough. With the HW tank in the garage,
the ambient water temperature might be > 90'F.

Seems like water heating in the summer would not consume very much power in FL (or Arizona, ...)

Hallowell International, maker of the new Acadia All Climate Heat Pump, is coming out with a heat pump water heater about now- maybe not till first of the year. Check out PRODUCTS on their web site- www.gotohallowell.com I have been speaking to them about the heat pump and the guy told me about it. See for yourself and give them a call.

Anyone have any experience with these?

FL_dude, did you follow up on any of the Dynamax info? It looks like they're a FL company, why don't you pay them a visit. :D I saw a price somewhere for $350, that includes an internal water circulator pump. The website in A/C Frank's post below is still good. That sounds real reasonable to me. With a heat pump, it would provide year-round water heating potential. I envision it plumbed to a water pre-heat tank, to heat ground water up to 90 degrees or so before it goes into the regular water heater. But you're right there's not much info online. Another brand-name they use which you can search is Aquefier.

I have a question for HVAC pros on here (including my buddy Designer Dan): The install manual says it goes "between compressor and reversing valve, if installed on a heat Pump System". Could that be right at the air handler? It would make for a pretty clean & sweet install if so!

Has anybody tried these?? Any risk of problems, from a system standpoint? Would it reduce winter heating capacity or would it just use "left over" heat?

Installs before the reversing valve on a heatpump. That has to be at the compressor, unless you are planning to run additional refrigerant lines to and from the AH. best place to install is either right next to the condenser or right next to the water heater, you have to pipe em both. It helps if the two are close together, less heat loss.
We have a few installed here in SC (Dynamax). They work fine. Yes, it does rob some of the heatpump output in the winter, but only when you are using hot water.

Thanks for the info. For a/c operation (the biggest benefit), I am thinking it might be best to have a pre-heat tank (another non-functioning hot water heater) which it would be hooked up to. Then it would have a large temperature rise and utilization when the a/c is operating, especially after using a lot of water. In contrast to hooking it up to the water heater, which would electrically recover and then the dynamax would only be maintaining temperature in the tank. Location wise, since it hooks into the compressor unit, I am thinking right inside the basement wall so that the a/c lines are minimal length but the unit is not outside.
