My propane ho****er heater is set to something like 135 degrees.
That means a lot of hot water is going down the drain.

I wonder - is there a calculation done on how much
energy it takes to heat 50 gallons of water with propane
versus how much energy it takes to heat a house by 5
degrees with propane?

Maybe it is cheaper to just heat the house more?

Whoa! Water temp. is at 135 deg and indoor temp. at 55 deg.?
If I keep temp. like that I'd have revolt from all member of
my family. That is barely ~14.5C. If OP has to keep it that way
how about changing shower head to water saving type? Any one in
the family catching cold? 135 deg. is lower than that of some hot
springs in the Rockies.

135 would be WAY too hot for me, and I like hot hot springs.



Probably blended with cold water.

Turn the temp of the water heater down.
