If you are planning to buy a water heater, then you should keep in mind that there are different types available on the market. You can find the details of all the popular types in the following section, but if you want to cut to the chase and buy a water heater, then you should go through consumer reports on best water heaters that consist of reviews of only top-rated water heaters currently available on the market.
Electric water heater
The electric hot water tank remains the most common. Currently, more than 45% of US households are equipped with it. Its operation is very simple. Electricity is supplied to a resistance that heats the water in the water heater. The principle is the same as for a kettle. It is the most economical mode of supply for a water heater because its installation does not generally cost more than 1,500 dollars.
Thermodynamic water heater
The thermodynamic water heater is a hybrid model which integrates a heat pump and a conventional water heater. It can be monobloc or split. In the first case, the two parts of the water heater are joined together, so you need enough space to install it. In the second case, the two blocks are separated and you can then place the hot water tank part in your bathroom. In terms of its operation, the thermodynamic water heater draws calories from the air, thanks to the pump, which it then returns to the bath heater. As a result, energy savings are very important. You can even reduce your consumption by 3.
The installation of this type of equipment costs, on average, 2,500 dollars.
Solar-powered water heater
The solar-powered device is the most environmentally friendly. It can provide between 40% and 70% of the hot water needs of a home, which still allows great savings. To operate, it requires the installation of solar panels. These solar panels are then irrigated by a glycol fluid which will pass the captured heat to the water heater.
For the installation of this type of equipment, count 6,000 dollars. Fortunately, there is a lot of help available to reduce your investment.
Gas water heater
It is also called an instantaneous gas water heater. This system has the advantage of heating your sanitary water quickly, but in return, you will have to remember to have the device serviced by a heating engineer each year for your comfort and your safety (just as for heating the gas boiler).
Other categories of water heaters
Water heaters don't just rank based on their technology. The type of installation and the mode of water production is also used to categorize them.
Mini water heater, vertical water heater, and horizontal water heater
There are 3 formats of water heaters. The most compact is the mini water heater. Economical, space-saving, it is perfect for small apartments and can be installed very easily on the wall of a bathroom. The vertical water heater, on the other hand, is the most efficient and practical, provided you have sufficient ceiling height. It can be installed on a wall, but it is usually placed on the floor. Finally, there are horizontal water heaters. They are good alternatives to upright models if you are short on overhead space, but they offer less performance.
On average, to have the same heating capacity as with a vertical model, a horizontal model will require an additional 50-liter capacity.
Instantaneous or storage water heater
There are two modes of hot water production: by accumulation or instantaneous. Accumulation models have a balloon with a certain storage capacity. They are particularly useful for families with high hot water needs. The instantaneous water heater does not have a balloon. Hot water is produced directly when you need it. As a result, the arrival of hot water at the tap can sometimes be quite long.
