How much do air injected shower heads cool the water?
I'm remodeling a master bathroom and I am considering a Hansgrohe rain head shower. However Consumer Reports says that some of the air injected shower heads they tested cool the water between 5 to 15 degrees between the time it leaves the shower head until the time it hits your back. While saving water is a good goal it doesn't help much if I end up using all of my hot water when I take a shower.
Does anyone out there have a Hansgrohe air injected shower head and if so how much does the air injection cool the water stream?
Thanks in advance.
