Many visitors to the Technodom online store contact us with a request to select heating boilers online. We are always ready to help them in this matter, especially since the range of our company includes many different types and models of equipment, suitable for literally any purpose. For example, if you need to select a gas boiler according to the parameters, then our consultants will be happy to provide you with all the necessary information. Before proceeding with the selection of heating equipment, it is advisable to determine which of its criteria will be most important for you.
Selection of the boiler by parameters (area, power, type of fuel)
Very often people carry out the selection of a gas boiler for a private house in terms of area and volume of the room. This principle works effectively with other types of boilers. With this data, you can determine the optimal equipment capacity for your building. It is believed that the ideal performance should be 100 watts per 1 sq. square meter. If you need to select a boiler for a private house, the price of this technique can also be of considerable importance. Finally, we advise you to pay attention to the type of fuel - and purchase exactly such a boiler, the use of which will be the most profitable and less costly for you.
The purpose of the boiler room
A private boiler room means a set of devices designed to provide suburban housing with heating and hot water. Its installation is necessary in cases where:
- the use of a centralized heating system in a private house is impossible due to the long distance to the nearest highway. In this case, solid fuel boilers are most often used (for an electric unit there is no need to arrange boiler rooms);
- requires independent regulation of the temperature of the coolant, which in a conventional heating system depends on the centralized supply and does not allow either to save money by reducing gas consumption, or, conversely, to increase the temperature in the room (for example, in severe frost), neglecting costs.
The advantage of this mini-complex is not only the ability to set the time and intensity of heating at the discretion of the user.
If we are not talking about gas boilers (which can also run on liquid gas), then the system using its own boiler room is non-volatile equipment that is not affected by interruptions in gas supply and various preventive maintenance work of utilities.
Selection of a gas heating boiler
For many of those who select a gas boiler by parameters, the cost of this technique can be very important, but not the only factor. In addition, it is worth determining its location - whether it will be wall-mounted or floor-standing. An equally significant factor in its volatility, the equipment can be autonomous or it must be connected to the mains. Finally, these models are single-circuit and double-circuit, the former provide only heating, and the latter provide heating and DHW heating. Employees will be happy to help you figure out all these subtleties.
Boiler room device
Since the project of the boiler room can provide for their installation both in a residential building and separately, the requirements for the equipment are also different. So, if the complex is located in one of the rooms of the house, in some cases (for example, in the presence of a noisy pressurized burner), additional sound insulation may be required.
While boilers installed in separate buildings are the safest and most practical option, although they require a relatively large capital investment.
The basic equipment required for the operation of a heating system, as a rule, does not depend on the location of the room, or even on the type of fuel used to operate it. Almost all boiler rooms consist of the following elements:
- heating boiler;
- boiler (water heater);
- expansion tank;
- distribution manifolds;
- chimneys;
- safety systems and boiler feed;
- pipes and valves.
Heating boilers
The boilers in this complex are heat generators. They burn fuel, due to which the coolant (usually water, less often - antifreeze) is heated and supplied to the hot water heating system and to the boiler (if any), which is necessary to provide housing with hot water.
A heated liquid circulates inside such a device, which increases the temperature of the water going to household needs.
Tanks and manifolds
The purpose of the expansion tanks is to compensate for the excess pressure of the coolant to eliminate the danger of creating an emergency in the heating system of a private house, in which pipes may burst.
A distribution manifold, consisting of a pump, a hydraulic separator and a comb, is necessary for the correct circulation of the coolant and its uniform flow into various circuits of the system (hot water supply, radiators, "warm floors").
Chimneys and security systems
Chimneys are necessary for the removal of combustion products from the boiler room. Not only safety, but also the efficiency of the boilers depends on how their installation is carried out and the parameters are selected.
And the tasks of the make-up and safety systems are to control the pressure of the fluid circulating through the pipelines. Only the first prevents a decrease in pressure due to leaks and evaporation, and the second, on the contrary, increases it, removing air from the pipes.
Automation and fittings
Automation installed in mini boiler rooms of a private house is necessary for the operation of the equipment (switching on, off, setting the required air parameters) in the absence of a person and providing additional safety for heating and hot water supply systems.
It may depend on the power supply (in this case, the boiler can operate independently for up to several days) or have mechanical regulators. Pipes and valves are required to circulate water in the system.
Selection of an electric heating boiler
In addition to the selection of a gas boiler for a private house by parameters, our clients are also interested in other types of these devices. For example, electric models are very popular. Such boilers must be selected according to their power indicators (this is a universal parameter for any models), the type of connection (220V or 380V), the principle of power regulation (stepwise or smooth), as well as the heating method (heating element or electrode). Each of the listed criteria can play a rather important role, therefore, we recommend that you pay special attention to all of them.
Equipment for water systems
Heating equipment installed in water systems allows large areas to be served with just one boiler. Water heating in it is carried out under pressure. The choice of the type of energy carrier often depends not only on the efficiency of use, but also on the availability of one or another fuel.
Gas boilers
Such devices are the most inexpensive and easy to use. If you choose a wall-mounted boiler, you can also save space in the room.
But for the installation of any gas boiler, you will need to obtain the appropriate permission from the regulatory authorities.
Floor standing boilers for domestic heating systems have massive cast iron or steel heat exchangers. The weight of the equipment exceeds 100 kg, and the power reaches 270 kW. Sometimes such devices are immediately equipped with a pump and an expansion tank, already representing a mini-boiler room.
Wall gas heating equipment has a lower capacity, rarely exceeding 60 kW (100 kW for condensing models), and weighing 30-50 kg. It is distinguished by almost silent operation and compactness. At the same time, additional elements may also be included in the kit.
Electric boilers
In the absence of the possibility of using gas, electrical equipment can be an excellent option for the efficient operation of the heating system. In operation, it is more expensive, but it takes up even less space, does not make noise at all during operation and does not require periodic cleaning of fuel combustion products. The power of electric boilers, in which heating elements are heating elements, is usually in the range of 2-60 kW.
For operation, such equipment requires mainly a 380 V electrical network, although some models with a power of up to 15 kW can also operate at a normal voltage of 220 V.
Solid fuel devices
Despite the fact that solid fuel water heating equipment has been used for heating for decades, its advantages and characteristics make it possible for such boilers to continue to be popular. Moreover, in the absence of gas their use is the most profitable.
A solid fuel boiler can be:
- A constant combustion device that works up to 8 hours after one load of fuel (coal or wood). Power usually does not exceed 50 kW.
- Long burning equipment, the operating time of which can be up to a week. The supply of energy (which can be firewood, coal, pellets, wood waste) is carried out in a semi-automatic mode, and the power of the unit can exceed 400 kW. Household models are available with a capacity of up to 100 kW.
Liquid fuel equipment
Liquid fuel boilers are most often used where there is no gas or high-quality power supply. In terms of their operational characteristics, they are comparable to gas equipment (power up to 19 MW), although models with a capacity higher than 50–100 kW are rarely needed for domestic purposes.
Their advantage over solid fuel equipment is the greater degree of work automation. However, the need to install such boilers in separate rooms, difficulties in storing fuel and low environmental friendliness make their use in private houses not very popular.
Selection of a solid fuel heating boiler
Solid fuel heating boilers are no less common; many visitors to the Technodom online store want to purchase this particular type of product. When choosing them, we advise you to pay attention to the fuel used by the boiler (coal, firewood, pellets, pyrolysis boilers enjoy considerable success), the method of loading it (automatic or manual), the material of the heat exchanger, the volume of the combustion chamber, energy consumption, etc. We will also be happy to help you choose a double-circuit boiler for an indirect heating boiler.
