What is a hot water tank? Advantages and disadvantages



A hot water storage tank is a device for storing drinking water as well as heating water. Hot water storage tanks are often part of the central heating system that indirectly heats the water. Larger households in particular can cover their hot water requirements inexpensively and efficiently with a hot water tank calgary , especially with renewable energies.

• Are you wondering what types of hot water storage tanks there are?

• Are you considering whether to opt for a hot water tank or a decentralized solution?

• Do you want to know whether renewable energies and hot water storage tanks are compatible?

There are two types of hot water storage tank: The water is heated directly in a so-called boiler. An indirectly heated hot water storage tank, on the other hand, is connected to the heating system. In this way, the water for heating and drinking water can be heated at the same time, which means that the costs and Carbon Dioxide emissions per liter of water are usually lower than with decentralized hot water preparation (such as with a flow heater).

The hot water consumption is decisive for the costs and Carbon Dioxide emissions of a hot water storage tank. The savings potential is often greatly underestimated.

Disadvantages of hot water tanks

However, hot water storage tanks also have disadvantages: In order to always be able to provide enough hot water and to prevent legionella, the water must be kept warm at all times. This causes memory losses. In addition, there are pipe losses that occur during transport from the hot water tank to the water taps. In order not to waste energy unnecessarily and to keep Carbon Dioxide emissions as low as possible, a hot water storage tank should therefore always be adapted to the size of the household and the habits of the residents. Good insulation of the hot water tank and pipes also contributes to the efficient use of hot water.

Hot water storage tanks are particularly suitable for a combination with renewable energies, as they can be used to temporarily store the heat that is obtained, for example, with a heat pump or a solar system. In this way, operating costs and Carbon Dioxide emissions can be reduced significantly.
