reducing DHW cost

I have a munchkin heating 2 hydronic coils for forced air, and I have a triangle tube 60gal tank as a zone for domestic hot water. Right now the tank is set very hot (probably close to 180), and there is a mixing valve to reduce the temp to safe hot. I have endless hot water.
My gas bill is about $45 for summer hot water. (dryer is gas also). I was wondering if I were to drop the temperature on the tank to 105, and consume the HW (rather than mix it). would I save gas? It would act like a normal 60 gal water heater, and would have a recovery window.
Is this a reasonable strategy to pursue with my HVAC guy?

Thanks in advance for your advise. I've benefitted so much from this forum as a homeowner.

Y Yes

Sure drop it down ........the lower the better to save fuel.............. Lowest temperature you can" Deal with " .......... 60 gallon set at 180*with a mix????? Where do you live Kappa Bata sorority house . Try 120*and adjust from there..

You don't ...

... want to drop the temp so low that Legionnaires becomes a concern. If you, family and guests are all in good health than 130* is likely to be OK. Otherwise, 140* is safer. I'm sure Dave Yates will have some thoughts on it :~)
