Heating of a country house with an electric boiler. Electric boilers for heating cottages: types of devices and their right choice
Yes indeed, heating gas boiler most economical and comfortable. But what to do if there is no main gas in your village, and no main gas is expected. And even if it is, then the amount that will be required for connection will be simply unacceptable for you ... In any case, the house will need to be heated. And here comes the solution - heating with electricity. But which heating system should you choose? Is it worth it to install an electric boiler with radiators, or will it be enough to bring electric convectors around your home. It is in this issue that we will try to figure it out.
In order to understand in detail the issue of heating and heating a private house or cottage, let's take for example a country cottage with an area of 100 m².
The laws of physics are the same for everyone heating appliances. And if it is necessary to spend 10 kW of electricity to heat a room of 100 m², then it does not matter at all which electrical appliance this energy will be taken. The electric boiler will take 10 kW, and warming up the coolant will give them to the heating radiators, however, while also taking energy to operate the circulation pump. Speaking of pumps. They should not be neglected when calculating electricity costs. Even a weak 50 W pump consumes 1.2 kW per day. This is already 36 kW per month. And now calculate the cost of the heating season ...
Electric convectors, without intermediate equipment, will themselves take electricity from the socket and directly heat the air.
Costs for the purchase and installation of convectors and a classic heating system on an electric boiler.
Electric convectors are installed in the same way as conventional heating radiators under windows. They do not require piping. All you need is to turn on the electric convector in the network. A 2 kW electric battery heats an area of about 20 m², of course, subject to the usual thermal insulation of the house. These are the same thermal indicators as the installation of a water heating radiator with a set of 10 sections.
By the way, let's compare the prices for a convector and a water radiator: The price for an electric convector 2 kW is from 2500 rubles. But to find even aluminum radiator heating with a power of 200 W from a section for 250 rubles a section (2500 for 10 sections) will be very difficult for you.
Now about the cost of installing a wall convector and a water radiator. It is quite obvious that it is incomparably cheaper to hang a light bracket on self-tapping screws (supplied with an electric convector) on a wall than to pull water heating supply and return pipes to a classic radiator.
The cost of the main equipment that is required to equip a boiler room on an electric boiler (excluding heating radiators) amounts to tens of thousands of rubles. Count for yourself - an electric boiler, circulation pumps, pipes (hundreds of meters), expansion tank, and certainly a coolant for pouring into the heating system. Of course, the installation of all heating units will also cost you a pretty penny.
In the case of arranging heating at home, giving electric convectors You do not have these expenses at all. Electric convectors do not require any auxiliary equipment. The most important thing you need is to find a good electric train that will not allow phase imbalance, correctly scatter wires around the house, and bring out a socket under each convector.
Home heating with electric wall convectors
Of the minuses of heating only electric convectors: If you do not have a coolant, then you will not be able to make yourself a water heated floor. But then again, you can always put yourself and electric floor heating in the bathroom, corridors, hallway. By the way, the electric floor heating can be turned on by a timer at the right time for you, thereby saving energy.
The second aspect is preparation. hot water. Only with a water boiler you can install an indirect heating boiler. With heating by convectors, you may experience a shortage of hot water if a large number of people live in the house. Conventional electric water heaters with a heating element heat water much longer than an indirect boiler with a powerful heat exchanger from a heating boiler. According to the passport, a conventional water heater with a volume of 100 liters warms up for about 4 hours. A boiler with a heat exchanger will heat your water in no more than an hour.
Advantages of electric heating convectors:
Possibility of individual settings. You don't have a coolant. Each electric convector is a separate independent heating system - it is an independent electric battery. No one forbids you to simply switch individual rooms and premises to anti-freeze mode with an air temperature of +5 degrees, or turn off room heating altogether. Moreover, electric convectors can start warming up the air even from sub-zero temperatures.
And we have already talked about the minimized cash costs for arranging the heating of your home. Buying electric wall-mounted heating convectors is several times cheaper than equipping a classic heating system with an electric boiler and heat carrier.
Heating of the house with an electric boiler and heating radiators.
Even with certain initial disadvantages, which are made up of the cost of arranging a classic heating system with an electric boiler, coolant and heating radiators, the classic heating system has undeniable advantages, and we will tell you about them now:
Advantages of the heating system on an electric boiler.
Never say never. you built yourself a private house or give. A lot of money has been invested in this. And if you don't have today main gas, then no one says that tomorrow this issue will somehow not be resolved according to the state program. If you already have a ready-made heating system with an electric boiler, then it will be enough for you to simply put an inexpensive wall-mounted gas boiler, or a floor-standing atmospheric cast-iron gas boiler into the heating system and your house will be heated by the cheapest type of fuel now - natural gas. The difference in electricity / gas costs is about ten times!!! And now let's calculate the costs that you will need to make to lay new communications in an already finished house. How do you lead the pipes through the walls or just along the walls, if the house has a ready repair. Of course, this is a real horror for the homeowner.
To the question of warm floors. Yes, electric underfloor heating is great. And if, nevertheless, you have been supplied with gas, then you will no longer open your tile to lay a water-heated floor from gas, but will be forced to use a more expensive electric floor to operate.
Be sure to also note the possibility of remote control of the heating system through modern GSM controllers. If you need, then for a long time you can simply keep the house at a minimum temperature in the room. But if you know that tomorrow, or in a day you will arrive at this pulp, then it is enough for you to reprogram the settings of the electric boiler by phone, and by the time you arrive, it will raise the air temperature to the value you need.
A wall-mounted electric double-circuit boiler is a rational choice that has a lot of advantages:
- relatively low cost of heating equipment of this type;
- ease of installation of the boiler, which can be done independently;
- minimum overall dimensions, allowing to place this equipment even in a small room;
- no problems with the supply of energy carrier, which is available in all settlements of the country;
- silent operation of the mechanism;
- no toxic emissions into the atmosphere, environmental friendliness of all equipment;
- no need for constant after-sales service, during which it is necessary to systematically clean the main elements of the boiler.

Rating: 867What kind of systems for heating their own houses and apartments has not been invented by mankind! Familiar, familiar to everyone or modern and non-traditional - there are many options, and the topic of this article is comfortable heating for a summer residence.
Of course, many are accustomed to gas equipment- economical and clean. Someone uses the old fashioned way, someone is looking for different non-traditional ones. But if your house is located in the outback and there is no gas main nearby, and you don’t want to constantly buy coal and firewood, or you don’t know how to properly heat them, then the option seems quite acceptable.
Scheme of a heating system with an electric boiler
There are only two cons, but they are not small. The first is dependence on the operation of the power grid, the second is tidy sums for the operation of a powerful boiler. The consumer asks the question: is there any on the market?
Usually in everyday life they use models with a power of 3 to 60 kW. But, as experience shows, a power of more than 10 kW will be excessive and can significantly overload the power grid. If you still decide to do it with the help of a boiler, then it is better to choose among capacities up to 5 kW. This value is quite enough for a house of 80 sq.m.
And in order to bring the characteristics of your boiler closer to other, more economical devices, then spend money on buying a more expensive model, but so that it has a built-in thermostat. Thanks to this device, there will always be a comfortable temperature in the house, there will be no overheating of the premises and excessive consumption of electricity. Do not spare money for a two-zone meter, which has a nightly rate much less than a daytime one.
Very good if in your heating system will be a heat carrier. And, of course, do not forget about the insulation of your home. Good thermal insulation will prevent warm air from “flying out into the pipe” and will make it easier for the boiler to heat the home.
Models of electric boilers
Not everyone knows that there is a difference between these devices, and a considerable one, and most importantly, it concerns the economic side. For example, single-phase boilers with the same power will heat the house differently. will heat 30 sq m, spending 1.2 kW / h. As for, he will try to save money - he will consume 0.6 kW / h of energy, but at the same time he will heat the area almost twice as much - 50 sq. m.
This example clearly shows the advantages and economic benefits of an electrode boiler, especially for summer cottages with their small area. Before making a purchase, calculate and correlate the dimensions of the cottage and the required boiler power.

Installation Safety Precautions
Before deciding the boiler, be objective in assessing your capabilities and do not overestimate your strengths. All installation work requires exceptional concentration and high literacy. The very placement of the elements of the system, its installation and connection scheme cannot be carried out without certain skills.
If you make an oversight, negligence in at least one process, then the consequences can be not only an ordinary equipment breakdown, but even a fire.
Only with a masterful approach can the entire system work efficiently and be safe.
And keep in mind that none can do without your control and is not a 100% guarantee of security. Any material used in electric heating boilers for summer cottages gradually loses its original characteristics, its quality deteriorates, and its shelf life decreases. Therefore, the owner of the house should regularly inspect the devices and control them.
The usual type of boiler made is a pipe or any other metal container into which it is inserted. The easiest way is to insert the design into the system itself. In this case, this capacity should be much wider than the rest of the pipes. Make it possible to remove it when replacing the heater.
Scheme of a homemade electric boiler
For a two or three-room house, it is enough to take steel pipe 50 cm by 22 cm. Both ends must be welded; at the top, make an entry for the pipe, from where the water will go to the batteries, in the lower welded cover - an entry for water that has already been cooled. The heating element is attached to the bottom cover or the bottom side. In the second variant, the heater must be placed on the other side of the pipe for the cooled water.
Choosing the right one, you select the assembly. But in any case, such components as an expansion membrane tank, safety valve, circulation pump and filters. In your independent frills, pay tribute to automation, and it is also desirable to use all kinds of regulators and sensors.
Such useful additions will greatly help in the operation of the creations of your hands, can significantly save energy costs and, of course, ensure the safe operation of all equipment.
