A tankless water heater provides hot water on demand. Unlike a conventional water heater, a tankless water heater doesn't use a lot of energy to keep a large tank of water hot. A tankless water heater in a mobile home can save from 14% to 50% in energy costs.
Taking Precautions With Gas
Federal, state and local codes tightly control the installation of heat generating appliances in mobile homes. Gas powered devices must be easily converted between LP and natural gas. If you are considering a gas tankless water heater, make sure that the model you select is designed for mobile homes.
A tankless water heater generates more heat than a conventional water heater. Most manufacturers recommend completely enclosing their tankless water heaters in a flame resistant enclosure or a room that is lined with flame resistant material such as gypsum.
An Electric Choice
Electric tankless water heaters are cheaper than gas heaters and easier to install. Electric tankless heaters generally have lower flow rates, which means they deliver less hot water per minute. This may not be an issue with a smaller footprint mobile home.
Electric tankless water heaters typically require a 240-volt electrical supply and from one two three 60-amp circuit breakers. Make sure your mobile home's electrical supply is up to these demands.
Placing Your Tankless Water Heater
An indoor tankless water heater in a mobile should not be placed in an unheated room. Exposing a tankless water heater to freezing conditions will result in damage to the unit.
A tankless gas water heater must be properly vented to remove combustion gases. Carefully follow manufacturer's instructions and building codes requirements. Most mobile home applications call for powered venting to insure that no gases leak into the occupied parts of the home.
Are You Up To The Job?
Installing a tankless water heater in a mobile home requires plumbing, electrical and general construction skills. In some localities, a licensed technician must complete plumbing and/or electrical work. Consider your skills carefully before attempting this type of project. If you have any doubts or don't meet licensing requirements, consider hiring a professional.
