Independent heating at home - choose your option

On a variety of options presented on the market today heating private houses - from the solid fuel boilers and heat pumps finishing. Most homeowners believe that heat the gas boiler house is beneficial, but users FORUMHOUSE know that under certain conditions it is - is not the best solution.

Due to the constant rise in energy prices and the high cost of connectivity, many developers care about the following questions:

• Are there alternatives to the trunk gas;
• What features may have different heating systems;
• How to calculate the price of a particular type of fuel;
• Is it advantageous to use solid fuel heating systems;
• How to heat a house with electricity and not to ruin;
• Can the home heat pump to replace the traditional heating system.

And the answers to these questions will help you find experts and users of our forum!

The main heating system selection criteria

Construction experience shows that the heating system private homes selected based on a variety of factors: the degree of the availability of a particular fuel type, the estimated monthly cost of heating, climate and living conditions heat loss from the building.

Heat the house in a temperate climate - this is one problem, and quite different demands are made to the system heating even in regions with colder climates than in Moscow, and many months heating season.

The efficiency of the heating system at home depends not onlyof heat engineering characteristics of the fuel and the efficiency of the boiler, but also on the design features of the house and the degree of heat.

Poorly insulated housing negates the work of the most highly efficient heating system!

Therefore, the choice of heating systems and boilers should be started even at the design stage of your future home. Any of experienced developers agree with the statement that there is no detail here, but any error or defect can lead to costly rework.

First of all, consider gas heating.

Alexander Hadynsky (Head "My fire" areas of heating systems)

The choice of heating system, first of all, depends on what kind of communications are brought to the house. If the main gas is already connected, then this choice usually results in fuel, because currently home heating due to gas main considered the best solution.

It is also necessary to consider ease of use of the heating system in different modes of living: daily, weekend mode, one-time visits. Only after weighing all the "pros" and "cons", you can choose the best option.
If there is no main gas heating is possible to build houses on LPG, The so-called gas-holder - a sealed tank, a buried at the site, and require periodic charging.

Advantages of liquefied natural gas as the main, it is - a clean exhaust, the ability to install chimneys compact and small boilers.

For all the merits, this auxiliary heating system of the house has a number of drawbacks.

Anatoly Gurin (CEO of "house engineering systems")

The main drawbacks of the gasholder include expensive plant, fueling an inconvenience, getting permits, the need for periodic maintenance by highly personnel. In addition, the gas tank on the site takes a lot of space.

Igor Larin (Head of «Boilers» WIRBEL)

choice of fuel, and hence the boiler equipment depends on the extent of its availability in a particular region. If there is a main natural gas, then the choice is obvious in his favor, if not - then it is necessary to assess the cost and availability in the area of ​​other types of fuel for heating.

The replacing gas

Advantages of gas are well-known, but they are offset by the extremely high price for his summing up. Consider the alternative.

Liquid fuel

diesel heating – It requires the installation of costly and complicated in the equipment.

It is necessary to find a place to install the tank for fuel. Diesel fuel has a peculiar and not all pleasant smell. Also, due to the constant rise in prices for diesel fuel hydrocarbon fuel heating it is one of the most expensive ways of heating the house. Among the main advantages of this type of heating is possible to allocate a high degree of automation of the boiler and the widespread prevalence of diesel fuel.

Electricity

Electric boilers are easy to use, environmentally friendly, safe and quiet.

Alexander Hadynsky

However, at low initial cost for equipment heated by electricity rather expensive, and when power outages can remain and no heating and no hot water. Also, the electric boiler will require a separate posting, and if it exceeds the capacity of 9 kW - three-phase network of 380 V.

In addition there are electric boilers heating appliances, such as electric heaters and infrared heaters.

The advantages of electric heating convectors and infrared heaters are the minimum initial costs and ease of hardware devices. You do not have to deal with arrangement of the boiler room, or conduct heating pipes. One would think - take it out of the box, plugged in and enjoy. But, as practice shows, not so simple.

Oleg Dunaev (Civil Engineer)

Well warmed house can be successfully heat electric heaters only when there are sufficient electrical power.

Among the advantages elektoricheskogo heating can be identified:

• a high degree of efficiency of the equipment;
• Easy installation;
• presentable appearance;
• the use of safety;
• programmable power-saving modes.

The disadvantages include:

• additional costs for high-quality wiring;
• increased demands on the quality of power supply elements.

Unlike the electric boiler for installation convector or infrared radiator are not required pipe laying Choose coolant consequently reduced ineffective energy consumption for heating the heating medium and the boiler tubes is reduced heat loss.

Here are the main criteria for the selection of such a heating system.

Oleg Dunaev:

- Choose the way: the power of the convector - up to 1.5 kW (more - melt plug and burn relay contacts).

Programmer - with its power source (the settings are saved when power is turned off). 10 sq.m. Square takes approximately 1 kW power convector.

Eletrichestvo - 380V, 3 phase, permissible power - at least 15 kW. Wiring section - 3h2,5 square millimeters Paving the dedicated converter and connect the line no more than three convectors per line.

Electroconvector best to hang at the window about 15 cm from the floor.

Electrical heating - one of the most expensive ways of heating the house. Seemingly cheap heating with electricity - is a myth. However, the user of our forum Alexander Fedortsov (Forum name Skeptic) On the example refutes this assertion.

skeptic (User Forumhouse)

I am a self-built frame is well warmed house on a foundation of UWB. At first, the project was supposed to heat the house in an area of ​​186 sq.m. solid fuel boiler. A little thought, I have decided that I do not want to become a fireman, and it is better to use night tariff and warm water in a makeshift storage tank 1.7 cubic meters

Water heated by electric heating elements per night up to 50 ° C, can successfully heat the house in winter with water floor heating system. A monitor the temperature by using a homemade regulator.

Alexander Fedortsov

In the boiler room, I put on a piece of foam density of 35 th and 10 cm thick. Well insulated heat accumulator - 20 cm mineral wool on the tank lid, on the walls - 15 cm. I can say that the cost of heating in December amounted to 1.5 thousand. rubles. In January, it clocked up no more than 2 thousand. rubles.

solid fuel

Firewood, charcoal, briquettes.

Alexander Hadynsky

Boiler for solid fuels (coal, wood) requires constant attention, virtually turning it into a host in a fireman. Such boilers can be used in places where no summed audio gas or electricity. They are the most accessible and cheap. When using solid fuel boilers is especially important to observe fire safety measures.

Igor Larin

The degree of autonomy in solid fuel boilers may be increased by using a buffer tank in the system - the storage tank. Due TA accumulates heat and reduces the number of tabs in the boiler.

The average coal-fired boiler during operation at one tab is minimally 3 hours up to 12 hours or more. The thermostat controls the air supply to the combustion chamber, and provides protection from overheating of a special valve and heat exchanger from overheating protection.

When using solid fuels the need for dialogue with companies supplying gasAnd obtaining permits for the installation of the boiler is eliminated. All regulated SNIP, which should be followed when design and installation of heating equipment. You should also follow the recommendations of manufacturers of fire safety.

As a backup heating system to power outage it makes sense to establish a multi-fuel boiler, or combine several heaters.

Alexander Hadynsky

Often an additional boiler is used to increase the degree of automation of solid fuel boiler, connected in an electrical circuit or fireplace boiler water circuit.

Independent heating in a private house by a combination boiler - an expensive option. These types of boilers are combined immediately three types of boilers - solid fuel, electric, gas or oil burner and are themselves expensive because domestic boilers. In case of power failure is better to connect an uninterruptible power supply that will allow during a power outage to continue operation of the equipment up to 48 hours.

Igor Larin

Combine different instruments could and should be for heating, especially in regions where there may be shortages of fuel.

It is practical system where solid fuel boilers are combined with wood-burning fireplaces, t. E. the system includes an optional heat source (fireplace) which maintains or accelerates the heating system.

The benefit from the use of multi-fuel boiler is the ability to combine the two types of fuel in the same equipment. In a boiler with two furnaces in one can burn solid fuel (wood, coal, briquettes), while in another set the burner (diesel or pellet). Thus, the homeowner, depending on the situation, may select the type of heating convenient for him.

Today is also a very popular pellet boilers

Anatoly Gurin:

The undoubted advantages of pellet heating are: autonomy, its cheapness relative to electricity and diesel fuel with propane. Among the shortcomings can be noted that it is necessary to find a place for the storage of pellets.

A low-quality pellets due to incomplete combustion reduces the efficiency of the boiler.

boiler itself require weekly attention, because necessary to clean the burner and fill the pellet.

continuous operation time of the boiler can be substantially increased by installing additional hopper for pellets.

In recent years become more and more popular alternative heating systems houses built on the basis of heat pump and the like (see. scheme).

Anatoly Gurin:

PRINCIPLE of operation - simple: heat pump moves warm air from the street to the house. The easiest way to introduce the heat pump as a refrigerator: Freezer - in the ground and radiator - in the house.

Experience in the use of such a heating system shows that, at a cost of 1 kWh of electricity, we have 5 kW of heat.

Despite the fact that such a heating system is known for several decades, many stopped by high initial costs required for its installation.

heating system - it is a long term investment in your home, and lower initial costs in the future high price to pay for the offset fuel and boiler maintenance.

The benefits of using a heat pump:

• lowest, 5 times less than the electricity for heating homes, heating costs;
• with air circulation from the street into the house exhaust absent;
• the system requires no maintenance;
• autonomy of operation: heat pump requires only electricity, and when power failure is easily heat pump can be powered by gasoline generator.

How do you know what is more profitable to heat the house

heating price includes the cost of fuel. Universal fuel, equally suitable for each region or at home, does not exist. It is therefore necessary to make the calculation based on the specific situation.

Igor Larin

When selecting the fuel can not be guided only by short-term profits, you need to focus on the long term.

Gas and never will be, but there are companies around the timber, respectively, will be (or already is) pellet manufacturers. In such a case, an effective solution is to supply boiler for solid fuels, which can then make a pellet (by setting a lower door pellet burner).

It may also be a situation where the gas should spend 1-2 years. At this time, you can put the boiler on solid fuel and then set the gas burner in it.

Anatoly Gurin

It is necessary to choose the cheapest fuel in the region. It is they who will be most advantageous to heat the house. For an objective calculation is best to make the summary table, which display the types of available heat sources, their costs of construction, operating costs and service life.

In the long term it is important to take into account such factors as the ease of use of the heat source. Experience shows that whatever the cheapest fuel, its low price can cross the minimum degree of autonomy of the boiler and the higher degree of attention to the operation of this equipment.

Alexander Hadynsky

It is necessary to conduct a brief analysis of the most likely ways of heating one or another type of fuel.

Knowing the power of the boiler, you can calculate the cost of heating costs per month. The approximate calculation - 1 kW is necessary to heat 10 sq.m. (Provided the distance from floor to ceiling to - 3 m), the stock is further necessary to take 15-20% required for hot water preparation.

On average boilers are about 10 h / day. The heating season in central Russia lasts 7-8 months a year, the rest of the boiler is working on the preparation of hot water in the house and maintaining a minimum temperature of + 8C.

results

Electricity: For thermal energy of 1 kW / h is consumed about 1 kW / h of electricity.

Solid fuel: For 1 kW / h thermal energy consumed approximately 0.4 kg / hour of firewood.

Diesel fuel: For 1 kW / h thermal energy consumed approximately 0.1 liter of diesel fuel.

Gas: For thermal energy of 1 kW / h is consumed approximately 0.1 kg of liquefied gas.

In the long run you need to take into account the increase in fuel prices, on the basis of the trends of recent years, and the payback period at a cost of initial investment.

Thus, the choice of the heating system consists of a set of measures and engineering solutions that require a balanced approach and a careful analysis of each situation.

Only then will your Vacation home It will be truly comfortable and modern housing.
