Every modern home should have hot water. But not all houses receive it centrally. And not everyone can purchase expensive equipment, install it and use the heating procedure. Heating elements will help with this. A heating element with a thermostat performs this task. The equipment allows heating and air. You can find many reviews about this useful device. Details about it are presented in the article.
What is this?
A heating element is called a tubular electric heater. This is the main part of the water heater, with the help of which the desired water temperature is maintained in the tank. This element converts electrical energy into heat. As a result, the water is heated up to a certain temperature set by the user.
Work is that the thermostat with the adoption of electriccurrent to the terminals passes it and transfers it to the heater terminals. The spiral heats up, gives off heat to the shell of the heating element, which heats the water. The device has a sensor that measures the temperature of the water. After reaching a certain indicator, the heating element with a thermostat is turned off. After it cools down, it turns on again. So the device works until disconnected from the network. Experts advise purchasing such a device in trusted stores.
TEN "Ariston" with a thermostat is considered one of the best. The heater contacts are treated with silver sputtering, which increases the rated current up to 25 amperes. This indicator in other similar devices is not more than 18. The Ariston heating element with a thermostat quickly heats the water due to good heat transfer. The nichrome helix has a high stretch factor. The devices are easy to install, light in weight and compact in size.
Composition of heating elements
The heating element includes the following parts:
- A tube that can be copper, steel, brass, titanium. All types have different performance indicators. A device that is resistant to corrosion should be selected. There should be a protective layer on the walls of the tubes.
- A spiral of wire that has a high resistivity.
- Filler that does not conduct electricity. Usually periclase is used. The filler serves to separate the coil from the tube.
- The contact rod is an element for connecting the heater to the mains.
- The insulators are made of porcelain and are located at the ends of the tubes.
- Tubular casing.
- Sealant.
- Thermal sensor that regulates the water temperature.
Types of thermostat
This device happens to be:
- Rod. Located in the tube on the heater body.
- Capillary. The tube contains a liquid whose object depends on water.
- Electronic. Responds to temperature changes.
There are also electromechanical thermostats. Their work depends on the properties of biometals. According to the functions, the devices are simple, dual-zone and programmable. Judging by customer reviews, the most frequently purchased are electronic ones. They are easy to use and affordable. Although often the choice comes down to personal preference.
Types of heating elements
TEN with thermostat may differ by:
- Designs.
- Mounting method.
- Material.
Equipment can be straight or curved in shape. Experts advise focusing on the design of the room where such a device will be located. According to the composition of the product design are:
- Tubular. This is a metal tube with a conductor. Inside is dielectric sand, which serves as an insulator.
- Closed. Dry is in a protective flask. In the space there is a special oil or quartz sand. This model does not come into contact with water.
According to the installation method, the heating element with a thermostat is flanged with a thread and a nut. Made using copper andstainless steel. Dry type devices use magnesium silicate, which is used to obtain a flask.
Application
Water heater with thermostat is used for various purposes:
- Heating. The device is installed in the battery using a connector. It should not be used for permanent heat generation.
- Water heating.
- Water supply to showers, sinks, sinks. For these purposes, the device is installed in a ready-made container.
Experts advise using equipment for its intended purpose if you want it to last a long time. The rules for its use are usually indicated in the instructions.
Benefits
Water heater with thermostat has the following advantages:
- Safety. This applies more to dry heating elements. No short circuit or electric shock. This is ensured by a design that does not involve contact with water.
- Long service life - over 15 years. The main thing is to follow the rules of use.
- Economy. This is due to the presence of a thermal sensor that regulates the supply of electricity.
- Easy to install. The heating element must be installed in the water heater, which is fixed on the brackets. Then everything is connected to the network. The boiler has all the necessary controls.
- Several thermoelectric heaters can be used in one heater.
- Resistant to mechanical damage.
Flaws
TEN with thermostat for heatingalso has disadvantages. But you should consider the type of equipment. With the burnout of the spiral, it will not be possible to repair the heating element. With prolonged use, scale appears, which affects heat transfer. Customer reviews confirm the negative aspects of the equipment.
Hard water shortens life. Dry types of equipment are not considered universal. They are created for specific types of broilers. Therefore, when repairing it, it will be possible to replace it only with a similar element. Experts advise you to use the device correctly, then it will not need to be repaired and replaced.
What affects the price?
TEN for water with a thermostat differs in cost depending on its type, modification. The price of open devices is low. This is a more affordable source of heat, especially if the body is made of steel.
Affordable are dry devices that have an empty flask. Heating elements with quartz fillers are considered more expensive. Please note that the cost of equipment depends on the price of service.
Choice
It is necessary to choose the right heating element for a radiator with a thermostat, as well as for other purposes. Usually, the purpose, the amount of electricity used, the heating mode, the installation option are taken into account.
When buying, you must inspect the body of the device. Copper appliances with a brass base are more expensive and have a longer life than stainless steel. It is important to look at the symbols indicated on the case. If athe letter “P” is indicated before the voltage indicator of 220V, this indicates the possibility of using water and slightly alkaline solutions.
For domestic use, experts advise using electric heating elements with a thermostat with a power of no more than 2.5 kW. The rest of the devices are used for spacious rooms. A heating element with a 2 kW thermostat for the home will be the most suitable. Must have thermal protection. It should be borne in mind that due to voltage drops, hard water, the operation of the device deteriorates. If any malfunction is found, experts advise replacing the device.
