Buying guides

Buying guides for buying a tankless water heater for the whole house

There are several factors to consider when buying a tankless water heater for your whole house, including the size of your home, how much hot water you use on average each day, your budget, and how long you want to wait for hot water.

1. The types and sizes

Tankless water heaters are available in several types and sizes, so the first thing to do when shopping for one is to figure out which type will work best for your home.

There are two main types of tankless water heaters: gas-powered and electric, with each having its own advantages. If you live in a small house or apartment, an electric tankless water heater might be a good option, since it can use less energy than gas-powered models.

However, if you have a larger home or want to run multiple fixtures at the same time, it’s better to go with a gas-powered unit. Gas units also typically offer more temperature control options than electric ones.

2. The power rating

The next thing to consider is the power rating for your chosen model of tankless water heater, also known as its “flow rate” or “BTU output.”

The flow rate refers to how much water your unit can heat at once; a higher flow rate will mean more hot water during times when many people are using it, but fewer energy savings than a lower flow rate.

The BTU output refers to how much heat the unit can produce at once; for larger homes or those with extensive plumbing systems, you’ll need a higher BTU capacity.

3. The size of your home

The size of your home is another important consideration when shopping for a tankless water heater. A larger home will need a more powerful and expensive unit, so you’ll want to make sure to get one with the capacity and features that are right for your needs.

For example, if you have very cold plumbing (such as pipes in an unheated basement), you may need a model with colder water settings, since colder water helps the unit heat water faster.

4. How long you’re willing to wait for hot water

Finally, you’ll want to think about how long you’re willing to wait for hot water when you need it. While tankless units can provide an endless supply of hot water once they get going, there is a short “startup time” before that happens—the amount of time it takes for the unit to activate, heat water, and actually deliver hot water.
