Al9226 told me that his residential water heater expansion tank idea worked great. He said he just replaced it after three years (as scheduled maintenance) and had never had a problem or any leaks I wentvwith a smaller one that I found on Amazon. I would have gotten a larger one, but they all had those clip connections and I couldn't use those because I'm going with a 1" line from the pump to the accumulator and I had to have threads. I'll post a picture later and a performance update once my season gets rolling.
For anyone who's considering trying this setup, I just got an email from the manufacturer of these power supplies that all you need is a 6 amp, 120 volt power source. So a very small generator would be more than sufficient for this! Also, he said to be sure you put a screen over your vent holes (if you use a box to waterproof it) as bugs can and will short it out. He said that heat build-up in a box would not be a problem as long as there are vent holes in the bottom.
VERY interesting. I'm assuming that, if you run this with a generator, the generator would have to be capable of producing 30 amps. Is that correct? Also, is it possible to use this to charge your battery and power your pump at the same time? (In case you have to use your battery as a back up)
Hi all! I'm getting my winter maintenance/upgrade list prepared and I'd really like to try out the "hot water accumulator upgrade", but all the tanks I've seen say that they have a polypropylene bladder (which is what the SH would be contacting directly) with a butyl diaphragm. Do you think the polypropylene would hold up on? (I ALWAYS rinse with 20-30 gallons of water after EVERY job) Thank you!
