[RE-wrenches] Testing LSAs

What is the best method for testing the integrity of a DC and/or AC lightning surge arrestor? Specifically, i use the Delta LA units. I know they should be replaced if they look Bar-B-Qued, but otherwise...? Thanks, Kris Schmid Legacy Solar 864 Clam Falls Trail Frederic, WI 54837 715-653-4295

Try the Takagi. I believe that all their units will modulate down to zero. Keep on eye on the temp rating of the unit...it is common practice to put the thermostatic mixing valve on the input side of the tankless. Kris Legacy Solar 864 Clam Falls Trail Frederic, WI 54837 715-653-4295 sol...@lega

Re: [RE-wrenches] On Demand Heaters for SDHW

Bill and Peter, I stand corrected. Tankless units do not modulate to zero. What a shame. My Takagi needs AC power to the exhaust fan in order to operate. I will be installing an aquastat relay on my solar storage tank that removes power to the Takagi when the solar tank is at or above 110 degr
