Quick Answer
Installing a propane tankless water heater in a mobile home is feasible but requires careful consideration of sizing, venting, and freeze protection to ensure efficiency and safety.
Sizing Considerations
When selecting a propane tankless water heater for a mobile home, you’ll need to determine the correct size based on the home’s hot water demand. A general rule of thumb is to size the unit for 2-3 gallons per minute (gpm) per person in the household. For example, a single-occupancy mobile home might require a 2.5 gpm unit, while a family of four would require a 7.5 gpm unit.
Venting and Vent-Free Options
Mobile homes often have tight spaces and strict venting regulations, making traditional vented propane tankless water heaters challenging to install. Vent-free propane tankless water heaters, like those from Bradford White or A.O. Smith, offer a solution. These units use a sealed combustion chamber, eliminating the need for a vent pipe. However, it’s crucial to follow the manufacturer’s instructions and local building codes for installation and certification.
Freeze Protection and Demand Control
To prevent freeze damage and optimize performance, consider installing a freeze-protected propane tankless water heater with a built-in defrost function or a separate heating element. Additionally, a demand-control device can regulate water flow and heat output based on actual demand, reducing energy consumption and prolonging the unit’s lifespan. This setup will also help prevent overheating and thermal shock, which can be detrimental to the tankless water heater’s performance and durability.
