I just installed my first electric tankless and wanted to give my positive recommendation to anyone considering quoting one. I was very unsure of the capability of the unit for a 3 fixture poolhouse, but saw no other good option as gas wasn't available and there was no good location for a tank heater. I purchased the Seisco brand unit for about $550.00 and quickly had it installed after sheetrock went up. Our electrician wired 220 to it and we tested it out. Turns out that it will supply about 3 gallons a minute of 110 degree water(77 outside). Was plenty for the 2 lavs and a shower. It's only about the size of a shoebox and weighed almost nothing. It has 2 tank type elements powering it and they are supposedly easy to replace. I was fairly impressed with the unit and can't help but think it would be a good reccomendation for all the greenies as well of those with limited space or small hot water demand J.R.
