I have recirculating pump attached to a 4yr old 50 gallon gas water heater, pump installed 8 mos ago when I redid my 2nd floor bathroom. Included new pipes (PEX), recirc pump, new shower system with 2 shower heads with 2 valves. I have noticed that I do not have enough hot water in my shower and the two showerheads are different temps, both valves turned all the way to HOT. Still, not quite hot enough. Rest of house has plenty of nearly scalding hot water, just not in the shower. And the showerheads are two different temps which is frustrating I have to turn showerheads off because I am not warm enough in the new shower. I have noticed the following:
1. I am not getting enough hot water in the shower, no cold needs to be titrated, and it is not hot enough for me.
2. Contractor thinks it is lack of insulation when he installed the new pipes to the other showerhead.
3. My father thinks it is the new valves are not mixing correctly or were not set up correctly.
I don't know. and the contractor will not come back out to the house so I'm stuck with a new bathroom and a new shower with dual showerheads that I almost cannot use. Any advice?
