What are the signs your hot water heater is going out?
Delivering Rusty or Cloudy Water
Rust deposits or a metallic odor coming out with hot water can signal either rusty pipes or rust inside the water heater. If corrosion is eating away the metal from the inside, leaks are inevitable. Murky water from the tap can also be signs that the water heater will fail soon.
What is the difference between direct vent and non direct vent?
Direct vent (two-pipe) vent system – This system uses one pipe to bring in outside air for combustion and another to remove exhaust gases. Non-direct (single-pipe) vent system – This system uses only one pipe to remove exhaust gases.
Why are power vent water heaters so expensive?
