For mobile home owners struggling with a limited hot water supply, a tankless water heater might be an appealing solution. These compact, efficient units provide endless hot water on demand, but can you actually install a tankless water heater in a mobile home? The short answer is yes, but there are several factors to consider before making the switch.

This guide will explore the ins and outs of installing tankless water heaters in mobile homes, including the benefits, considerations, and steps involved. Whether you’re tired of running out of hot water or simply looking to upgrade your home’s water heating system, read on to learn if a tankless water heater is the right choice for your mobile home.

Benefits of Tankless Water Heaters for Mobile Homes

Tankless water heaters offer several advantages that make them particularly well-suited for mobile homes.

Endless Hot Water Supply

One of the most significant benefits of tankless water heaters is their ability to provide a continuous hot water supply. Unlike traditional tank heaters that can run out of hot water after extended use, tankless models heat water on demand. This means you can say goodbye to cold showers and waiting for the tank to refill and reheat.

Energy Efficiency

Tankless water heaters are generally more energy-efficient than their tank-style counterparts. They only heat water when needed, eliminating the standby energy losses associated with keeping a large tank of water hot at all times. This can lead to lower energy bills and reduced environmental impact, which is especially beneficial if you want to minimize utility costs.

Space Savings

Mobile homes often have limited space, making the compact design of tankless water heaters particularly advantageous. These units are typically wall-mounted and take up significantly less room than traditional tank heaters. This frees up valuable floor space in utility closets or other areas of the home, allowing for more efficient use of the available space.

Considerations Before Installing Your Tankless Water Heater

While tankless water heaters can be an excellent choice for mobile homes, there are several factors to consider before making the switch.

Gas or Electric Supply

Consider whether your mobile home has an adequate gas or electrical supply to power a tankless water heater. Gas models typically require a larger gas line than traditional tank heaters, while electric models may need upgraded electrical service to handle the increased power demand.

Water Flow Rate and Temperature Rise

Calculate the required water flow rate and temperature rise to check that the tankless unit can meet the home’s hot water demands. This involves considering factors such as the number of fixtures you’ll use simultaneously and the desired water temperature increase.

Installation Requirements

Mobile homes have unique installation requirements due to their construction. Think about venting options, available space for the unit, and any necessary modifications to the existing plumbing or gas lines.

Types of Tankless Water Heaters Suitable for Mobile Homes

There are several types of tankless water heaters you can install in mobile homes, each with its advantages and considerations.

Gas-Powered

Many people prefer gas-powered tankless water heaters for their higher flow rates and lower operating costs. However, they require proper venting and a sufficient gas supply. When choosing a gas model for a mobile home, select one that’s compatible with your home’s gas type (natural gas or propane).

Electric

Electric tankless water heaters are generally easier to install and don’t require venting. They can be a good choice for mobile homes without natural gas or propane access. However, they typically have lower flow rates than gas models and may require home electrical system upgrades.

Point-of-Use

Point-of-use tankless water heaters can be an excellent solution for mobile homes with limited hot water needs or specific problem areas. These small units are installed near the point of use, such as under a sink or in a bathroom, and provide hot water for a single fixture or small area.

Steps for Installing Your Tankless Water Heater

Installing a tankless water heater in a mobile home requires careful planning and execution. While it’s often best to hire a professional for this task, here’s an overview of the general steps involved:

  1. Choose the Right Unit: Select a tankless water heater based on your home’s needs and available utilities.
  2. Obtain Permits: Secure any necessary permits and ensure compliance with local codes.
  3. Shut Off Utilities: Turn off the water and gas or electricity supply to the existing water heater.
  4. Remove the Old Heater: Safely disconnect and remove the old water heater, clearing the installation area for the new unit.
  5. Install the New Unit: Follow the manufacturer’s instructions to mount and install the new tankless water heater. Include venting for gas models if required.
  6. Connect Utilities: Hook up the water lines and either the gas line for gas models or the electrical supply for electric models.
  7. Install Safety Devices: Add necessary safety devices, such as pressure relief valves, for safe operation.
  8. Test the Unit: Conduct a thorough test of the unit to check for proper operation and that there are no leaks.
  9. Adjust Settings: If needed, adjust the temperature settings to achieve your desired hot water output.

Cost Considerations

According to Angi’s cost data, tankless water heaters generally range from $1,397–$3,889, with gas models typically being more expensive than electric ones. The price variation is due to differences in brand, capacity, and features.

Other potential costs may include:

  • Upgrading Gas Lines or Electrical Services: This could range from $800–$4,000, depending on the specific needs of the installation.
  • Venting Installation for Gas Models: Proper venting might add an additional $2,500–$6,000.
  • Permits and Inspections: Securing permits and arranging inspections could cost between $50 and $500.

While the up-front costs may be higher than replacing a traditional tank water heater, the long-term energy savings and improved performance can make tankless water heaters a worthwhile investment for many mobile home owners.

Tankless Water Heater Maintenance

Here are some key maintenance tasks to keep your tankless water heater working well:

  1. Annual System Flush: Flush the system annually to remove mineral buildup, especially in areas with hard water. This helps maintain efficiency and prolongs the life of the unit.
  2. Inlet Filter Screen: Clean or replace the inlet filter screen periodically to prevent debris from entering and damaging the unit.
  3. Regular Inspections: Inspect the unit regularly for signs of leaks or other issues. Addressing small problems quickly can prevent more severe damage.
  4. Professional Service: Have a professional service the unit annually, including checking all connections and safety devices.
