When choosing a water heater, your first decision is if you want to purchase a storage water heater or a tankless water heater. While in the US, storage water heaters are still quite common, the most popular type in Europe is the tankless. There are many reasons why a tankless water heater is the best choice, including energy-efficiency, longer lifespan, saving money, and less space required.
The common storage tank heater has a large container of water that is kept hot until use. Once the hot water is used, the tank is refilled with cold water and heated up again. It wastes a lot of energy keeping the water heated constantly.
A tankless water heater, on the other hand, will heat the water in transit, circulating the water through electric coils or gas burners that work only when the hot spigot is cut on, when you’re through, the burners or elements shut down.
A tankless water heater can last up to 20 years, a good investment if you are planning on staying where you are for a lengthy amount of time. In contrast, a typical tank water heater will only last 10-13 years.
While a tankless water heater costs more to purchase, in the long run, it saves the consumer money. Your tankless heater is not running constantly, so your power bill will be considerably less. Also, because it is considered energy-efficient, in some areas you can qualify for utility rebates with your electric company or the home improvement efficiency tax credit.
A storage tank water heater can take up a significant amount of space, especially in larger homes. A traditional tank heater can be up to 60″ tall and 40″ wide. A tankless unit can be a quarter of the size, usually around 28″ by 20″ by 10″, and will need less insulation. This is also good if you wish to purchase a point-of-use water heater, it requires much less space beneath the sink.
Gas vs Electric
Pros of Gas
— Gas costs less than electric
— Heats more water faster
Pros of Electric
— Electric is safer, no danger of a gas leak
— Life expectancy is longer because electric heaters have fewer parts that may need replacing
— More energy efficient than a tank that uses a pilot light.
