When you are in a hurry and want to heat water quickly, you need an instantaneous water heater. This device provides you with water at a good temperature and without limits. Read this article to discover some useful information that could help you choose your tankless water heater.

Criteria to analyse before choosing

The first thing to analyse is the type of energy. Electric water heaters are easy to use and can be installed without the intervention of a professional. Their consumption varies according to the water setting. On the other hand, water heaters that heat water by combustion are quite economical and are the most recommended for bathrooms. They do not require regular maintenance, but only one service per year. As far as power is concerned, it should be between 3.7 and 5.5 kW if you want to heat water for a washbasin. For dishes, the power of the appliance should be between 5.5 kW and 7.7 kW. However, to meet the different water needs of a shower room, the heater should be more than 11 kW.

The particular advantages

Providing hot water quickly is not the only advantage that this heater can give you. The use of this device does not increase your energy consumption but on the contrary, you can save quite a bit of energy by using it. The incredible advantage is that if you choose a good tankless water heater, you will enjoy its operation for more than twenty years. With this appliance, you are spared the problems of bacterial proliferation because it does not cause water stagnation. This device is not at all bulky because of its smaller size.

The different prices to be expected

Before choosing the device, you should take into account two parameters. In addition to the cost of the device, you should also consider the cost of installation. In addition, if there are plumbing problems that need to be solved beforehand, the cost will be enormous. However, if you choose an appliance of up to 4.5 kW, you should expect to pay no more than €280 including VAT. But for an appliance of up to 6.5 kW you should expect to pay a maximum of €380 including VAT.
