The sizing information available is very confusing because manufacturers, and others, are trying to provide a simplified answer to a complicated question.

Some suggest that you calculate by the number of bathrooms in your home while others say to go by the number of people in your family. Also, in many cases, their recommendations are based on the worst case scenarios, assuming higher consumption than your actual water use.

Gas-powered heaters, on the other hand, can work well in any environment and have a higher output, but they are less efficient than electric heaters and require specialized ventilation. In general, an apartment or condo with one bathroom will need an automatic, instantaneous water heater with about 3. An average-size home between 1, and 1, square feet with two bathrooms will need a residential tankless water heater with a GPM of around 7.

A large house of more than 1, square feet with three or more bathrooms will need a high-flow tankless water heater with a GPM of close to 10 — or maybe even more.

All in all, the best tankless water heater for your home is going to be one that meets the GPM requirements of your home.

As for their durability, gas tankless heaters last longer than electrical models by design.

Electric tankless heaters are automatically cheaper than their gas counterparts, but the price of a gas tankless heater depends on whether it is condensing or non-condensing.

Condensing water heaters do not need a fancy ventilation system but cost more upfront, while non-condensing water heaters are cheaper but require proper ventilation. Electric water heaters also have the edge on installation.

Even though it still requires a plumber, unless you need to upgrade your breaker amperage installation should be relatively straightforward.
