Buying guides

Buying guides for buying a tankless water heater natural gas

When it comes to choosing the right tankless water heater, there are several important factors that you will need to consider.

1. Size

One of the most important factors to consider when buying a tankless water heater is size. You will need to determine how many people you on using the hot water with and what your daily usage patterns are like in order to determine which tankless water heater size will be best for your needs.

Conclusion

Propane and natural gas heaters are the most efficient type of tankless water heaters. If you have access to a natural gas line, we recommend choosing a natural gas unit over a propane one. Electric tankless water heaters are also very popular because they’re easy to install and don’t require any special electrical hookups.

However, electric models are less energy-efficient than either propane or natural gas units. So if saving money is your primary concern, stick with a model that uses either propane or natural gas as its fuel source.
