Re: Not enough hot water - house has 2 WH connected together.

The typical showerhead has a gpm rating of about 1.5-3 so even at 3 gpm's you should have enough hot water for 12-14 minutes. That's at full hot so when you mix in 40% cold water now you have a 20-22 minute shower. Add in the fact the water heat should be making new hot water and a 30 minute shower isn't out of the question. Reduce the 3 gpm head to 2 gpm's and now you have a 45-50 minute shower. If you can't get that the water isn't hot enough so either the thermostat on the water heat is too low or it's not heating the water correctly.

We have a tankless water heater hooked to a 50 gallon water heater. That's unlimited hot water!
