Manufactured homes need hot water just as much as any other home, but space, energy use, and installation requirements can be different. Traditional water heaters take up room and store water that constantly needs reheating. A tankless water heater heats water only when you need it, saving space and reducing energy bills. For manufactured homes, the right tankless unit can mean faster hot water, lower costs, and a cleaner installation.
This guide will start with the best tankless water heaters for manufactured homes, then move into a buying guide, installation advice, and maintenance tips so you can choose with confidence.

Key Buying Factors for Manufactured Homes
Fuel Type
Manufactured homes may run on electric, propane, or natural gas. Electric models are easiest to install but require proper electrical capacity. Propane and natural gas models heat water faster but require venting and professional setup.
Flow Rate (GPM)
Choose a GPM based on your usage. One bathroom with light kitchen use can get by with 3–4 GPM. Two bathrooms or higher demand might require 5–6+ GPM.
Climate
Colder incoming water temperatures reduce a heater’s effective flow rate. If you live in a cold climate, choose a more powerful model.
Installation Space
Measure your available wall space and check clearance requirements for safety and airflow.
Noise Level
In smaller homes, noise can be noticeable. Look for models known for quiet operation, such as the Stiebel Eltron Tempra Plus series.
Installation Tips
- Check local building codes for manufactured homes
- Ensure electrical or gas connections meet manufacturer requirements
- Mount in a location that’s easy to access for service
- For outdoor units, protect from extreme weather
- Hire a licensed professional for gas or high-capacity electric models
Maintenance for Long Life
Tankless units need regular maintenance to run at peak efficiency:
- Flush annually to prevent scale buildup
- Clean inlet filters every few months
- Inspect for leaks or loose fittings
- Check venting for blockages in gas models
Conclusion
The right tankless water heater can make a manufactured home more comfortable, efficient, and modern. If you have propane, the Rinnai V65iP offers excellent flow and reliability. For electric homes, the EcoSmart ECO 18 is a great value, while the Stiebel Eltron Tempra Plus 24 delivers premium performance.

By picking the right size, fuel type, and features, you can enjoy endless hot water without sacrificing space or efficiency — making your manufactured home even more enjoyable.
