Horizontal water heater: dimensions, design and diagram

ek.ua

Water heating devices are truly replete with their species diversity. But what each option does, why there are so many of them, no one can say. We will try to give as much useful information as possible about the design of a horizontal water heater. Let's get started!

Horizontal water heater design

A horizontal water heater is a reservoir, inside of which there is a certain number of heating elements (heating elements). Their quantity directly affects both the price of the model and the speed of heating water in the system.

The body is made of a steel base coated with protective enamel or other materials. All walls have a thermal insulation layer in order to increase the efficiency of the device and reduce heat loss during prolonged heating of the tank.

If you actively use a horizontal heater, then you have definitely noticed that it is not hot water that flows from the tap, but warm water. This is another feature of the equipment - volumetric mixing of cold and hot water.

Pros and cons of a home heater

Horizontal water heaters have a large number of positive qualities, which is why users love them:

• they keep warm for a long time;
• easy to install;
• they have a low energy consumption parameter;
• relatively low operating power compared to competing models (for example, flow-through heater);
• simple design, provided with protection;
• a wide range of devices from a dozen manufacturers.

As with any other equipment, you can also find its disadvantages here:

• For proper operation, it is necessary to constantly clean the device from scale and rust;
• The dimensions of the horizontal water heater are large, so they are not suitable for “modest” rooms;
• the price is above average among heaters.

What is affected by the material of the device tank?

The first thing that determines the price of such equipment is the material of the water tank. Let's look at all the types in detail:

• Stainless steel. If you use this option, then it is necessary to install a magnesium anode (a rod that prevents the appearance of scale inside the system; requires constant replacement). It is most widespread among the model range: both expensive and cheaper. Everything will depend on the design of the device.
• Enameled walls. The main advantage of the format is no harmful effect on water and a lower price. As in the previous version, a magnesium rod is required.
• Glass porcelain is somewhat similar in characteristics to enamel. It differs in that it does not need an anode at all and does not crack when maintaining a high temperature in the system for a long time.

Differences in connection method

This category includes horizontal devices of open and closed type:

• Open (non-pressure) - used to service one point (for example, turn off one tap). This device does not require special attention and careful maintenance. Put a tank of 150 liters - and live happily ever after.
• Closed (or pressure) - they operate over the entire area of ​​the apartment, therefore they require an entrance for hot and cold water.When the hot water supply is turned off, the device automatically switches the system from transmission from the network to transmission through the boiler.
