So, **is 120 good for hot water**? The answer involves a careful balancing act between burn prevention, bacterial growth, and energy efficiency.

Did you know that the World Health Organization recommends a minimum indoor temperature of 64°F (18°C) for healthy adults? Understanding **what is the lowest safe temperature for a house** is crucial for preventing health issues and costly structural damage, especially during cold months.

Studies show that a gas water heater typically recovers its hot water supply twice as fast as an electric one. Understanding this fundamental difference is the first step to knowing exactly how long does hot water take to recover and how to minimize your waiting time.
