The device and principle of operation of the boiler

Before choosing a suitable boiler, you should familiarize yourself with the design of the heater. Main elements:

• Tank. The container where the water is heated. May differ from model to model in inner lining and seams. The thicker the walls of the product, the stronger the welds will be. The inner surface is enameled or stainless steel.
• Heating element. Heating element, consisting of a nichrome coil, which is enclosed in a copper casing. "Dry" heating element is covered with an insulating layer, which significantly increases its service life. The shape of the heating element and its dimensions may vary.
• Thermostat. It makes it possible to control the temperature of the boiler and protect the heating element from overheating. It can be mechanical or electronic. In terms of reliability, both types are not inferior to each other, but electronic is considered more accurate.
• Magnesium anode. This element provides protection to the boiler structure. It prevents corrosion of the inner surface of the heater. It can be stationary or removable.
• Frame. Effectively insulates internal processes from heat and water loss. It is made from different materials and has different shapes and designs.
• Thermometer indicator. Shows the temperature regime in the boiler. Mainly located on the front of the heater for easy access.
• Power cord. Mainly 3-core covered with identifying insulating materials. Green-yellow is connected to the body, and brown and blue to the terminals of the temperature controller.

Tips for choosing water heaters

Before choosing a water heater, you need to pay attention to the technical parameters of the device:

• Volume of the tank. The larger the boiler capacity, the more hot water is produced at the outlet. The most used tank sizes are 30, 50, 80, 100 liters. On average, for a family of two, a heater with a 50 liter tank capacity is suitable.
• Power. The rate of water heating directly depends on this indicator: the more it is, the sooner the user will receive hot water. On average, the power of work is equal to - 1.5 kW.
• Control system. There are mechanical and electronic systems. There are no special differences between them, the choice will depend on the wishes of the buyer. Boilers with an electronic control system are somewhat more expensive.
• Installation method. There are wall and floor heater installations. The choice between them will depend on the preferences of the client.
• The form. By the type of body, cylindrical models are considered the most popular. They are characterized by ease of use. Rectangular are distinguished by great manufacturability. Slim heaters have a more compact body.
