Hello Everyone,

Newbie here. I moved into a new house back in June with a tankless hot water heater (burnham minuteman II).

I am running into problems as of late, with cold showers. Hot water only lasts 2 minutes then it gets luke warm at best. And this is on the first shower of the morning!

I have adjust the temparature setting upward and also make sure there is enough pressure in the system as well.

What else can I do? I thought tanklesss hot water systems you were suppose to have an endless stream of hot water?

My bathroom is 2 floors up from system.

Thanks for your help.
