The most economical gas boilers for home heating

Question of price

Domestic models will be the cheapest. Equipment produced in Europe is more expensive (sometimes several times). The cost is also affected by whether you are going to purchase a condensing or convection boiler. The classic type, convection, will cost less. Efficiency also affects the final cost. The lower the coefficient, the cheaper the equipment.

On average, foreign equipment costs 30-50 thousand rubles. The most expensive and high-quality devices will cost 100-120 thousand. Domestic models stay at around 20 thousand rubles.

Which gas boiler is better to choose?

This section is intended to tie all previous discussions to real life, because theory and practice are different things. Theoretically, everything is correct; the most economical gas boiler with the highest efficiency is a condensing boiler. But having learned how much this miracle of technology costs, not everyone will dare to buy it. And is there such a need?

Take the same gravity system, which does not require pumps, automation and electricity. It is not advisable to buy an expensive heat source for it, although a turbocharged or condensing heat generator will cope well with such a system. It will simply force the coolant to circulate forcibly from its own pump. The question is the reliability of power supply and the decent price of equipment, which will pay off when it is unknown.

It is also not very reasonable to buy a condensing boiler for a small house of 100 square meters. m of area with any heating system. In such an area, you are unlikely to feel the efficiency compared to an inexpensive aspirated engine. You can see a real difference if a country cottage with an area of ​​over 300 square meters. First, heat it with a simple boiler, and then change it to a condensing boiler.

Types of devices based on the heating principle and their description

Below are the main types of boilers operating on the principle of energy conservation:

• heating elements . They are equipped with a tubular-type heating element that heats the moving liquid.
• Induction . The principle of their operation is based on magnetic induction. In this case, the ferromagnetic alloy is heated inside the coolant.
• Electrode (ionic) . Units of this type combine advanced developments with a high degree of efficiency. They heat water by passing an electric current through an electrolyte solution. Its molecules are converted into cations and anions. The result of this process is the release of a significant amount of thermal energy.

Single-circuit and double-circuit

An electric heating boiler can be one of two main types:

1. Single-circuit . Designed for heating rooms by circulating liquid inside radiators and in a closed circuit.
2. Dual-circuit . They can not only heat your home. but also provide it with hot water supply. They are compact and some can be placed on the wall.

Advantages and disadvantages

The advantages of different types of energy-saving boilers are approximately the same and are as follows:

• Very high efficiency - up to 99 percent.
• During operation of such a device, soot and ash are not released, and oxygen is not burned out of the air.
• The equipment operates completely autonomously.
• Easy installation, management and maintenance.
• Minimum noise level during operation.
• High level of safety due to automatic power supply shutdown when there is no liquid in the heat exchanger.
• Relatively low price level in comparison with gas heating equipment.
• There is no need to install a chimney or arrange a place to store coal or firewood.

The list of main disadvantages looks like this:

• Electric shock hazard.
• Special requirements for the quality of water used for heat exchange. In case of non-compliance, the equipment will not last long.

Features of operation of electrode boilers

Advantages:

• high efficiency indicators - at least 95% efficiency;
• good environmental friendliness;
• combination of high power with small overall dimensions;
• is not afraid of electrical voltage surges.

Flaws:

• the need to use alternating power supply;
• periodic monitoring of electrolyte conductivity;
• arrangement of reliable grounding;
• you need to install a pump to circulate water in the heating system;
• Electrodes need to be replaced every 2-4 years.

Features of electrode heating boilers Numerous reviews will help you choose the best models of electrode boilers for heating a private home.

The efficiency of such units is due to the excellent shock-absorbing system and the use of economical fuel. No maintenance required. Electrode equipment has a longer service life.

What if the boiler consumes too much fuel/energy?

Perhaps the increased consumption is caused by a malfunction in the system, blockages or other factors in the unit itself or in the circuit. In this case, you should not immediately buy a new boiler. To get started, contact Profteplo. We will carry out diagnostics, find the reason for the high fuel consumption of the boiler, find the points of greatest heat loss, etc.
