Quick Answer
A 100lb propane tank is suitable for heating water, but you'll need to consider the tank's BTU capacity and the demand of your water heater. Generally, a 100lb tank can provide enough propane for a small to medium-sized household with moderate water-heating needs.
Propane Tank Sizing for Water Heating
When determining the size of a propane tank for water heating, it’s essential to consider the BTU (British Thermal Unit) capacity of the tank. A 100lb propane tank typically holds around 420,000 BTUs of energy. For comparison, a standard water heater requires around 40,000 to 50,000 BTUs per hour to heat water. This means a 100lb tank can provide enough energy to heat water for several hours, but it may not be sufficient for households with high water-demand needs.
Factors Affecting Propane Tank Sizing
Several factors influence the size of the propane tank required for water heating, including the number of people in the household, the number of bathrooms, and the type of water heater used. For example, a household with multiple bathrooms or a large family may require a larger propane tank to meet their water-heating needs. Additionally, the efficiency of the water heater and the insulation of the tank also play a role in determining the required tank size.
