The choice of the tank for heating water depends on the size of the room and the preferred principle of operation. The accumulative water heater can be an autonomous device or part of the heating system.
Types of storage water heaters
The gas boiler is becoming more and more popular due to high prices for electricity. High power allows you to heat a large volume of water in the tank in about an hour, when the temperature drops, the gas burner automatically turns on. For installation, a resolution of the relevant authorities, equipment of a special premises and a separate chimney will be required.
The electric boiler is equipped with a thermostat, which allows you to heat water to a boil, and then maintain at a given temperature level. When the tank is empty, the heater fixes a decrease in water level and automatically replenishes the desired volume. Then it takes the temperature of the water to a given level.
Economic boilers do not differ by efficiency, and due to low power heating a large volume of water 2 times longer than gas. But easily mounted and save the area of the room.
Water -water boilers work from an autonomous heating boiler, are considered the best option for a country house. A spiral is installed inside the heating device, which circulates water from a common boiler. This type of heater warms the water as quickly as possible, unpretentious in maintenance and is easy to install.
The main criteria for choosing a storage water heater
Regardless of what type of accumulative water heater will be preferable to you, all of them have unified standard characteristics that are taken into account in the production and operation of the boiler.
The volume of the tank
Large units eat the area of the room and require significant maintenance costs (electricity, gas). Therefore, the volume of the tank should be chosen based on the compactness of a particular model and pay attention to the level of resource consumption. For a small family, a 120 liter boiler is enough.
The power of the water heater
Gas water heaters are twice as powerful than electric. If the choice is still inclined in favor of the second, then you should take a closer look at the models equipped with two tens. New, ergonomic electric boilers have an automatic shutdown function. If the difference occurs in the voltage, the boiler will work in the usual mode, with a decrease in the load on the network, the second ten.
The internal coating of the tank
Today, the most popular and inexpensive tanks have an internal coating of enamel or fiberglass. Such coatings reliably protect the tank from corrosion, but as a result of temperature differences, more than other materials are subject to the formation of microcracks. Therefore, enameled tanks have the shortest warranty period.
Bucky with titanium spraying is well opposed to corrosion, light and have a guarantee of up to 10 years. Their weak place is welding places.
Tanks covered from the inside with a traditional stainless steel — the most resistant to corrosion option. Stainless steel does not react with water, and does not affect the taste characteristics.
Almost all modern models of storage water heaters are equipped with special magnesium anodes for additional protection of the tank from corrosion. They need to replace them once every 6 months, and stainless steel tanks are much less common.
Water heater safety
When choosing a boiler, it is better to give preference to models with a heat -insulating layer of heat -resistant materials.
In addition to the main thermostat responsible for the level of water heating, high -quality and safe boilers are equipped with an additional thermostat and an external temperature sensor.
Installation of a storage water heater
Gas boilers must be installed in accordance with all the stipulated security standards, so it is better to entrust the installation to professionals.
When installing an electric water heater, the aggregate fastening is of particular importance. In addition to the elements of fasteners, which are included in the kit, it will not prevent the design of the design with additional details. The most reliable option is anchors with fasteners. Two such anchors installed on the load -bearing wall withstand the load up to 300 kg.
After fixing the boiler on the wall, they proceed to connecting pipes to supply and drain the water. It is better to connect the wiring elements using polypropylene materials.
Powerful water heaters will require additional wiring, a small power unit can be turned on in a regular outlet. Experts advise to carry out grounding without fail.
Adviсe:
1. For small rooms, manufacturers offer models with a horizontal location of the tank, which can be installed under the ceiling.
2. Installation must be carried out taking into account unhindered access to the water heater for prevention and repair.
3. Water heaters with an electronic control system are suitable for city apartments. For giving, there are decent options with mechanical control.
