The best water heaters for a modular home are efficient and have a small footprint. The efficiency and compact size of electric tankless water heaters make them a great option for modular homes.

A gas-fired water heater is another good option if you have the space. Another excellent choice is a tankless water heater which is very efficient and can save you money on your energy bills.

Tankless Water Heaters

Tankless water heaters are a great option for those who have limited space and want to save on their heating costs.

  • Installing them is quite inexpensive.
  • The heaters in this category come with either an electric or gas option.


  • They are not as energy-efficient as gas-fired models.

Factors to Consider When Choosing a Water for a Modular Home

  • Size of the unit
  • Type of fuel
  • Efficiency
  • Cost
  • Warranties

Size of the Unit

One of the first things you’ll want to consider when choosing a water heater is the size of the unit.

The size of your water heater is determined by two factors: how many people live in the house and what type or amount they need to heat daily.

Type of Fuel

The type of fuel you use to heat your water will also play a role in your decision. The most common fuel types are gas, electricity, and propane.

Each has its benefits and drawbacks that you’ll need to consider.


Another important factor is efficiency. Energy-efficient water heaters will help you save on the monthly bills.

There are two efficiency ratings for water heaters: first-hour rating and thermal efficiency.


The cost is another critical factor to consider. Water heaters can range from around $300 to $2000 or more.

You’ll need to decide how much you’re willing to spend on your unit.


When purchasing a water heater, be sure to check the warranty. Most units come with a standard warranty of around six years.

However, you may be able to find an extended warranty if you shop around.
