: It seems more phase III's (instead of the boiler co tank) could be set up with the boiler water sides in parallel to provide buffer tanks and the domestic sides in series to provide infinite hot water. Then the whole operation could be held to about 150F.
Yow! That sounds like an expensive proposition. Aren't those Phase III's like $2000 apiece? And they only hold about 8 gallons of boiler water.
How about the reverse indirects....are they substantially more than the Lochinvar, which is $1150 plus freight?
Are there any reverse indirects with 2" boiler taps?
