Point taken, but IMO overdramaticized. To clarify, a tempering valve should be used so that the user is not cooked. Does that help?Sting wrote:option one as it is provides NO SCALD PROTECTION

redundant -- since you already have the coil in the applinaceNJJoe wrote:Thanks so far guys, please keep them coming. What about option 4? No love for the ergomax?
I am quite familiar with the attitudes. I don't want to try to speak for the AA/AHS guys and I don't think I need to. Anything I think I might know about AA/AHS equipment is only from what I've seen on this forum. If anything, for someone with zero AA/AHS experience, I thought my original wording was pretty neutral regarding EFM's vs. AA/AHS's. "That's my story and I'm sticking to it."Townsend wrote:Mike, you have been around long enough to know the virtues of the AA/AHS without resorting to the "probably" clause!!! Or at least certainly know the attitudes of the Axeman men and how they feel about their boilers. Come on, you can do it, admit they're just as good as the EFMs, only different!!!
Nice rhyme.Sting wrote:it Depends Mike
when the appliance is on a low sustained idle - it is simply holding temp
there may not be enough energy in the box for option one to heat the leg to 120
and yes - the protection valve does the trick -- when it functions correctly and doesn't stick
My coil was in a steam boiler with a single aquastat that controlled only the low limit. IIRC it was set at 160 deg in the summer. The boiler water needs to be enough above 120 degrees that the cold incoming water can reach 120 degrees during the limited time it's running through the coil. That said, the first blast of coil water coming out at 160 can use some tempering, and the first blast that comes out while you're making steam can use a lot of tempering.fifthg wrote:mixing valve is good,but scalding shouldn't be an issue if you don't set the upper limit too high.There is no need to do so.The hotter you go,the harder on the system,so there is another reason not to.
