These days, when purchasing a new water heater, people are usually torn between getting a tank or a tankless heater. Both of these types have their own unique sets of characteristics that need to be taken into account. If you are also faced with the dilemma of tank vs tankless, let us help you make up your mind by outlining key features of these water heater types.
These types of heaters are considered standard and somewhat low-tech. Even though they are cheaper, they are more costly to run, because they need to keep a tank full of water at all times, and at a predefined temperature. With such a heater, each time you use the hot tap, the tank will be filled with cold water coming from the main water supply. After that, the heater will bring that new water to the desired temperature. The heating elements a tank heater uses are between 3kWh and 5kWh of strength, with many heaters using two heating elements. This amount of watts usually results in bigger monthly utility bills; therefore, it is somewhat important to pay attention to that characteristic.
In addition, when compared to the tankless heaters, tank ones are more popular with homeowners, because they can provide massive amounts of water, regardless of the size of the household. They can be used in all kinds of households, from small apartments to large villas and even commercial establishments. Of course, the larger the tank, the greater amount of hot water is available. Also, keep in mind that, depending on the size of the tank heater, you will need an appropriate storage room.
Tankless Water Heaters
As opposed to the tank heaters, tankless models do not feature a tank for storing water. As a result, they are considerably smaller and more convenient.
A tankless water heater will only heat the water when you use the hot water tap. Therefore, a tankless heater does not have to keep a water tank hot at all times. Given that a tankless heater allows the heating of water on demanding, you can expect lower heating bills, much less than those that come with using a tank heater.
However, due to their size and working mode, tankless heaters are mostly incapable of providing enough hot water for larger households or bigger families. If there is a constant high demand for hot water, a tankless water heater simply cannot heat up the water supply quickly enough. This usually results in frequent shortages of hot water. Therefore, if you live in a smaller household, with limited utility space, a tankless water heater will be a better option than a tank one.
