FAQ:

Q: How hot is the water from a tankless water heater?

A: Depending on the brand and model, most tankless water heaters have a temperature setting that is adjustable between 100° to 140° (most tank water heaters are set around 120°). In order to make sure the water will be hot enough, it’s important that a tankless water heater is sized based on your climate and hot water needs.

Q: Can water heater catch on fire?

A: The “CTH” series tankless electric water heaters are designed to attach to cold water pipes. They heat the water just before it is used. The pressure switches used in these heaters are defective and may cause the heater to explode and catch fire.

Q: Can a water heater burn my fish?

A: A fish getting burned by a heater might be very rare, but that does not make it less problematic. If you are worried about this happening to your fish you can take precautions by covering your aquarium heater in a plastic protector. This is the first and major way to protect your fish against these burn marks.

Q: Can water heaters overflow?

A: The water heater overflow is also called the pressure relief valve. This safety device will vent a water heater if the pressure inside becomes too great. Because of that, the overflow cannot be compromised or replaced with a plug.
