Floor-standing gas boiler - a good solution for heating private houses
Modern boilers are made of refractory materials (steel, cast iron), which accounts for their durability. Availability of automatic mode (automatic scheme is in the device data sheet) makes for house heating boilers safer to use and easier to manage.
Floor standing gas boilers for home heating. Types of gas equipment
For the operation of domestic gas boilers used gas (LPG or natural), gives off heat during the combustion of the heat exchanger device. The water passing through it is heated and distributed to the heating system. boilers are divided into wall and floor by location. For installation of gas boilers floor is given a special place on the floor or a separate room to heat your home.
Modern boilers are made of refractory materials
In order to decide which outdoor boiler is better suited for your home, you need to have an idea of the types of equipment and the specifics of his work. You can familiarize with the scheme outdoor gas boiler.
Gas floor boilers are divided into types by the following characteristics:
- manufacturing a heat exchanger material (iron and steel);
- Since the burner;
- Output method of combustion products (atmospheric, forced);
- the number of loops (single-loop, two-circuit);
- power;
- moving the coolant circuit.
In the selection of the gas boiler is necessary to consider two quantities: the heat losses of the building and the required amount of hot water
Life time gas-fired boiler manufacturing a heat exchanger depends on the material. For performance characteristic iron corrosion resistance and burn-through. Such a device can last more than 50 years, but is rather a fragile product. Steel embodiment is robust and resistant to deformation, but is non-corrosive and prone to rapid burn-(up to 15 years).

Choosing the boiler output to heat your home
The main indicator when choosing a floor gas boiler for heating private houses is a power of the instrument. This figure provides room space you want to heat. Today, manufacturers are admitted boilers of various capacities that can provide warmth like small homes, and a complex of several buildings.
Basic embodiments boiler power calculation
According to power boilers floor is divided into single-stage, two-stage and modulation (infinitely variable). The two-stage boiler fitted with two modes of power. A modulation scheme setting is arranged so that it is possible to control the power, it gradually changing. For private houses with a small area (or temporary residence) such boilers have received positive feedback. What better outdoor gas boiler for heating private houses in your area, consult an expert.
Useful advice!In order not to doubt the chosen boiler capacity, the calculation must be carried out exclusively by a qualified heating engineer company specializing in this field.
Floor gas boiler in sectional
For the user, it will be sufficient to have an idea of what to provide heat to the room of 10 squares (up to three meters high) enough 1kW power. This value is valid for a well insulated house. If your house is not, should choose a more powerful boiler. Power selection also depends on whether the equipment is supposed to participate in the provision of hot water. If this is meant the component power increases from 20% to 50%. Holders of the heated pool, you must first focus on the selection of two-circuit boiler with an increased load on the power. Specifications on the boiler output specified for the nominal pressure. If a little pressure, then, respectively, and the capacity of the unit will decrease.
Owners of pools, with heating function is better to choose double-pressure boiler with an increase of the load capacity
Single and dual-circuit models
When choosing outdoor gas boiler for heating private houses, it will be necessary to determine the type of equipment and device. There are two options: Single and dual circuit. Single-circuit gas-fired boilers for heating private houses are only designed for the heating of the heating system. Scheme their design is such that they can not operate to supply hot water. It is therefore necessary to additionally acquire the device for heating water or acquire model with built boiler.
As for the double-circuit gas-fired boilers for heating private houses, then they can work on the heating system and the heating of water for household needs.
Apparatus gas condensing boiler with integrated boiler
Gas bypass device floor boiler to heat your home:
- gas stove;
- a heat exchanger;
- expansion tank;
- circulation pump.
Turbofan boiler It operates so that if necessary, heating the water heating system is switched off and the equipment is working on hot water. Since the use of hot water is not constant, the heating system temperature does not change significantly. Driving device shows that for correct operation of the equipment, it is necessary to connect the boiler to the heating system and to bring hot water faucets.
The principle of operation of the gas boiler furnace
Useful advice!Installing a private house floor Turbofan boiler, it is necessary to consider the length of the pipe from the device to the hot water faucet. The maximum length should not exceed seven meters.
Floor gas boiler is large in size and weight. Under it should be to equip the house floor space (arrange / reinforce screed) or placed in a separate indoors, and also to provide separate suction channel for removal of spent combustion products fuel.
Boiler room in a private house
If your house does not have a centralized hot water supply, it is best to choose an effective gas combi boilers floor, which follows from the reviews.
The principles of operation of the gas boiler and types of combustors
According to the functional principle of heating gas heating appliances are divided into convective model and condensation. The convection boiler characterized in that the combustion products from the outside is removed and steam arising during the combustion gas. In models of condensing steam and the combustion products are directed through a heat exchanger wherein the vapor condenses and gives extra heat. Which of these boilers is better definitely does not say, because the convection is no risk of corrosion due to condensation. For their production, you can use a less expensive material, and their price is much lower (as evidenced by reviews). Furthermore, the combustion products are removed by natural draft.
The operating principle of a condensing boiler with two heat exchangers
Condensing boilers are high efficiency through the use of additional heat, but, along with this, the heating system must be staffed overall and expensive heating radiators. User reviews help you navigate some of the options better.
The combustion chambers in gas boilers can be closed or open. The convection equipment uses both types of cameras. The condensation - a closed type combustion chamber.
Floor gas boiler is large in size and weight
The open cells due to natural draft combustion air taken from the room where the boiler is installed and removed through the chimney. atmospheric burner used in these devices. Devices with an open camera should be mounted only in a separate room equipped with a chimney and a vertical position. Judging by the reviews, the cost of such boilers is quite low.
Useful advice!Choosing boiler with atmospheric burner, consider the fact that they operate almost silently and long, but at the same time burn oxygen in the room.
Maintenance of gas boilers trust only professionals
Floor combi boilers with sealed combustion chamber can be installed directly in the heated room. It used herein forced draft - electric fan draws waste products from the combustion chamber. The chimney has two tubes (one inside the other): the outer pipe for sucking air inside - to be output. Performance of such boilers is very high, but such units operate only when there is electricity. Feedback from users of such equipment are positive.
heating circuit of a private house with a gas boiler
heating schemes are developed in-house based on what is supposed to circulate coolant - natural or forced.
Natural - on the basis of the difference of density of water of different temperatures. This scheme is used when the location is available at a level below the boiler and radiators observed, corresponding to the circulation, the slope of the forward and reverse wiring system.
Typical heating water circuit and cottage
heating circuit wiring are monotube and twin tube. When one pipe circuit wiring heating elements have different temperature: the lower radiators receive water already partially cooled. And if the house is more than one floor, the temperature of the radiators on each floor is different. This will help to avoid a further increase in the sections, or the installation of a jumper. When one pipe routing system uses a small amount of material. This layout is typically used for small houses.
Two pipe layout requires a large consumption of materials, but the heating elements are heated equally. double pipe routing system allows to adjust the water temperature in the different areas by means of locking valves.
