Ok, so I had a heater that was very inconsistent and felt like ran out too quick for its size. It got us by. But it got to the point here it was lit and burner was burning, but the only water that would come out of the hot water side of faucets were just "not cold"...not even warm. I looked on the unit and it was from 1991. I didnt even debate fixing it vs getting a new one. Got a new one, I installed it...somewhat without any hitches. Now same thing, but just a tad warmer. Water is only warm throughout house. I have thermo set on what should be 130 degrees. Pilot is lit, blue flame burning. Its been almost two days so its not an issue where its just not all the way warmed up. No water leak...water meter is still when nothing is running.
Im clueless. Dont know what to do or check next.
Any ideas?
