Is it profitable to put a boiler in the apartment

Advantages and disadvantages of water heaters

The conditional disadvantages of boilers are limited to the time of installation of the boiler. you will have to spend 2-3 hours for installation, as well as the need to allocate space in the bathroom or toilet, where you can put the device. However, the design of modern boilers allows you to make them a part of any interior, without violating its integrity and harmony.

The advantages are obvious: you can choose the desired temperature of water heating, and the rest of the warm water to use for another day without having to include the device again. If you have cold water and electricity, you will always have hot water, and even cheaper than the centralized supplier.

Types of water heaters and criteria for their comparison

All devices for water heating for economic needs are divided into 2 groups: storage boilers and flow-through water heaters. The first are a tank of a certain volume, where the water is heated in various ways to a maximum of 75 ° C, after which it can be used. Flow-through heaters (aka. columns) are designed to “on the fly” to raise the temperature of the flow passing through a heat exchanger.

The main element of the storage water heater is the tank with a capacity of 35200 liters

There are 3 varieties of water heaters sold in stores for private homes and apartments:

  • Electric and gas water heaters;
  • Storage boilers that run on electricity or natural gas;
  • Indirect heating boilers.

Users usually wonder which option is better. a gas water heater or an electric water heater, because these 2 varieties are the most popular.

The secret of popularity is quite simple. These household appliances are superior in their qualities: they are more reliable, more efficient and cheaper. To put an electric boiler is more difficult. the device consumes more power, so it is not suitable for installation in apartments with old wiring or with a small power limit.

Due to the lack of a tank, the size of flow heaters is much smaller

Gas storage water heater for hot water also can not be attributed to the in-demand household appliances. Column to use more convenient, and put it easier. In turn, the storage boiler indirect heating is used in conjunction with another source of heat. a heating boiler. These hot water tanks hold 100300 liters, occupy a lot of space and are offered in 2 versions: floor-standing and wall-mounted.

We will compare the electric boiler and a gas boiler by 3 criteria:

But first it will not hurt to understand all the advantages and disadvantages of these water-heating devices.

Briefly about the construction and principle of operation

In order to save money, users try to turn on the boiler on a certain schedule. But if you want to reduce energy consumption when operating a hot water heater, you need to understand in general terms, how it works.

Home Heating and Energy Saving Tips From Worcester Bosch Group

The picture below shows an accumulation boiler. insulated tank of stainless steel or enameled steel with built-in tubular electric heater (TEN), having its own thermostat. On the bottom there are water inlet and outlet spigots, as well as (or on the front panel) is the heating regulator and thermometer.

The main elements of electric water heater

The algorithm of operation of the water heater is as follows:

  • Through a branch pipe, equipped with a check and safety valve, the tank is filled with cold water. Heating elements turn on automatically and heating process begins.
  • When the contents of the tank reaches a temperature set by the user, the thermostat turns off the electric heater. If there is no tap water intake, the automation maintains the heating at a predetermined level by periodically switching the heating element on and off.
  • When you open the tap on any faucet, the water is drawn from the upper area of the tank, where the corresponding connection is derived.

For your reference. Boilers can be not only electric, but also gas. They are heated not by the heating element, and by combustion of liquefied or natural gas. On the comparison of different storage units with flow-through columns told in our other publication.

To ensure that the electrochemical reactions that arise between dissimilar metals in the heating process, do not cause corrosion of the steel capacity, it is equipped with a magnesium anode, which takes the “blow” on itself. That is, due to the activity of this metal, the rod is gradually destroyed instead of the tank and the heating element.

How to understand whether it is worth installing a water heater? Pros and cons

Utilities are constantly becoming more expensive, and the centralized supply of heated water is often disconnected. In this regard, many people wonder if you need a water heater, will it give any benefits? To fully understand this, you need to understand what features boilers and flow-through models have, as well as how much they spend on their work.

For a rational reduction of energy costs it is worth to understand the design of the water heater. It is executed as a tank of stainless steel or steel with a layer of insulation. In the steel tank is built in magnesium anodes, which prevent corrosion and electrochemical reactions. Tubular heater with a thermostat built into the tank. In the lower part of the tank are the pipes that supply and return water. On the front or bottom panel there is a thermostat and a thermometer.

  • Cold water is poured into the tank through the hose with valves. safety and return valves.
  • Heating elements turn on automatically and heats the water.
  • When the water in the tank reaches the desired temperature the heater is turned off by a thermostat.
  • In models without hot water heating level is maintained in automatic mode. the heating element turns on and off after a certain period of time.
  • When the hot water tap on the faucet is opened, a special pipe draws water from the upper part.

What water heater is better to choose in a private house. flow or storage

For the organization of independent hot water supply (DHW) of apartments and private houses 2 groups of heaters are used. boilers and water heaters. The former gradually accumulate heat in a tank of 30 500 liters, the latter heat water “on the fly”, immediately after opening a tap. We propose to consider the pros and cons of each type of household devices and find out which water heater is better. flow-through or storage.

Features of installation

Floor standing storage water heater is the easiest to install. It is installed in a pre-prepared place strictly on the horizon. If you want to mount the device on the wall, then you need to choose a sturdy building structure. After all, a filled boiler weighs hundreds of pounds. Typically, wall-mounted large storage heating tanks are mounted on a supporting frame of metal. A steel corner is used for its construction.

Pros and cons of hot water

Hot water is the default in every apartment. This fact is taken for granted and people rarely think about the advantages and disadvantages of centralized water supply. Issues arise if the quality and system of water supply ceases to meet regulatory standards.

Pros of using hot water:

  • No restrictions on the amount consumed. Water of the right temperature runs immediately from under the tap, no need to wait for heating when using any volume.
  • Ability to install meters that allow paying only for the consumed volume.
  • No additional financial and time costs for purchase and installation of equipment.
  • Responsibility of the resource supplying and managing companies for the uninterrupted supply of water and maintenance of networks to the meter. Will not have to deal with equipment maintenance on their own.

Disadvantages of centralized hot water supply:

  • Periodic scheduled and emergency water cutoffs for reasons beyond the customer’s control.
  • Regular increases in utility bills.
  • Impossibility to control the temperature of water coming up. Often, due to the negligence of utility companies, worn-out networks and heat loss, not hot water runs from the tap, but warm water. It is not always possible to get payment adjustments.
