Great Tips for Choosing Water Heater

Hot water for shower, bath and kitchen is a matter of course. But it is also a convenience that takes a lot of energy. As part of reducing energy consumption, while maintaining the convenience of the house, choosing the right water heater. It is not always economically justifiable to change only to reduce energy consumption. A new salesperson costs a lot of it. But when a new one is still on the agenda, it's good to think about a little before the purchase.

Separate water heater is not always necessary

It is not all households that need a separate water heater. Several heating systems also include solutions for hot water in the drain faucets. But not everyone. Sometimes one or more separate water heaters are needed for household needs. When it comes to heated homes, it can also be a convenience measure, which makes the job easier during the summer, when the house does not need any heating. A water heater will then provide heat to the water without the need for fire.

Heater with accumulator tank

The classical water heater consists of an electric heater or a heat exchanger and an accumulator tank. The electric cartridge ensures that the water stays warm all the time. There are also models where the heat sink warms shields around the mixer, which in turn warms the water. This type of water heater is good to have if the water in the faucets is hard. The lime coating may otherwise destroy the electric cartridge and the entire dispenser breaks down.

Water decides

Water not only determines which heating model is the most suitable in the choice of water heater. The inside of the dispenser can be covered with either enamel, stainless steel or copper. The quality of the water affects which one is the best. At low pH, stainless or enamel is preferred, while copper is good at high pH values. If you have municipal water, you can get information about what water quality applies to your particular location.


One of the big questions about the choice of water heater is the size required. A larger water heater takes more energy, but on the other hand, the hot water needs to be enough for everyone in the house. Here is a list of approximate sizes for different needs: - 60 liters and below works for the summerhouse. If the processor holds 60 liters, it is also possible to take short showers. - 200 liters are often fine in a household of four people. Then a bath or two can also be considered. - 300 liters are needed if a hot tub and other items are on the agenda for those living in the house.

Most households do the best with a caterer for all needs. But there are, of course, exceptions to that rule, like all other rules. This applies especially to the one who has provided his house with his own small spa, which may be used sometime a week. One salesperson can then be used for daily use, while another is being put in front of the spat. Then the cost of amounts of hot water is not paid every day, but instead if necessary.

What place does the caterer take?

The next question is how the salesperson should look. If it can be placed in a storage room, it will usually be a hanging or standing model. The same applies if it can be mounted in the basement. Hanging models are almost a necessity if they are to fit in the bathroom itself or in the kitchen. Sometimes it may be required for the model to lie. Please measure the space available before purchase. Otherwise, there may be a problem.

Keep the water warm!

Saving energy by keeping a lower temperature in the water heater with the storage tank can pose a risk. Then bacteria can begin to thrive in the water. It can then cause diseases of those who use the water. One of the more dreaded diseases that can be spread in this way is legionnaire disease. It manifests itself as pneumonia.

NOTE! If you keep at least 60 degrees in the water heater, you do not worry about bacterial growth. Instead, put on a water heater that has good insulation, which is energy-efficient. It may cost a few extra dollars, but it will be spent on the lesser energy consumption over time.

Flow Cleaner

Another variant is a water heater that warms the water as the water flows through the reservoir. Such a water heater is called a flow-through processor. This type of water heater may be suitable in many contexts, especially at drainage points where hot water is needed in larger amounts, or when the hot water is rarely needed. Namely, in a throughput heater, the hot water never ends and the dispenser draws power only when water flows through it. The downside is, however, that the throughput processor requires a lot of power when used properly. This means that it can not be installed anywhere, since the fuse system must be adapted to the high temporarily load.


In addition to the purchase of a water heater, it is necessary to connect it to the existing power system. An authorized electrician is required for the work, and it costs a few hundred pieces. Keep in mind that you can use the root deduction for this service!
