HTP's Phoenix Water Heater for Heating

hr

a Voyager in my shop as backup to my wood boiler. I think they basically added the Munchkin/ Contender burner to the old Voyager tank.

Actually this is an excellent idea A modulating, condensing heat source with buffer built in! I like the electric element back up idea a lot, nice option.

Is it available with the internal coil like the Voyager?

I don't know if they are available yet? I saw Morgan at AHR Dallas a few weeks back. He is excited about this product.

This could be close to the ideal low temperature radiant heat source.

HTP's Phoenix Water Heater for Heating

Hey all,

a contractor working with a client of ours wants to use this water heater:

http://www.sensibletechnologies.net/pdfs/phoenix/hsc/proddata_phoenix.pdf

Naturally we would use an external heat exchanger to separate the radiant. Normally I am skeptical of water heater claims of super efficiency, but this one actually makes a direct combustion efficiency claim of 95%.

Anyone used it?

I'm not sure how I feel about it... 95% sounds pretty good, but we would otherwise run a mod/con at 100 degrees here... probably a little higher in efficiency, and this is not condensing. But I have to admit any improvement over 95% would be incremental.. and this is basically, if the claims are real, a very high efficiency source and buffer all in one.

So, just wondering, since I'd not seen it before... anyone had any experience with this unit and any feedback?

Thanks in advance!

Here's a better link

more info on the unit. I just called the rep, and they are selling out of them faster than they can get them in. Apparently it's out!

Very intriguing... I'm still having flashbacks to the Polaris days, and vague claims of "94% thermal efficiency" which doesn't really say anything... but the fact that they specifically call out combustion efficiency makes me wonder if this one is for real.

Apparently it IS condensing as well.. no built in coil version, which is too bad, but since you'll probably want to mix down from 120 anyway to give the radiant some reset I don't see it as a big deal. Injection pump, HE, system pump, simple injection controller... good to go.

only a 33kBTU minimum modulation, but with a minimum 60 gallon buffer I don't suppose that's too bad.

argh.. we have a policy of not using first gen tech around here, generally, given that first release products always have bugs. But it's going to kill me to wait on this one.

FWIW HR, I have heard through the grapevine that you are correct, this is in very basic terms a voyager style tank with a Munchkin style burner.

Any feedback on the Voyager tank? Sounds like it's pretty solid.

not sure why an electric backup coil would be of any use though. I could see it for, say, a solar storage tank, but what's the premise here? In case you run out of gas??

I've had

a Voyager job. Had trouble but had great support from HTP. I had 2 tanks leak into the combustion chamber. Took out the ignotor to check it and had water gush out. Yikes! There was trouble with the connections at the top of the combustion chamber where it split into 3 flu passages. Lots of stress there and lots of cracks. I also heard they were changing the material at that location to fortify it. Also changing to condensing would lower the flu temps at that spot and lower the stress. Soiunds good, but have been shy about trying it again. I had the inside loop HX that ran a radiant floor off of it. After losing the second tank I switched to a mod con with indirect and have had no problems. WW
