Water heating boilers - choose the best option
Thermal power of any system is to compensate the heat loss in a room withoutdoor temperature during the heating season.For example - in Moscow, it will be -26 ° C, but in Yak
When choosing a water heating system, you need to calculate the approximate heat output - so you reach the maximum effect of the heating system.For a country house used this calculation - 1 kW power at 10 m2.This calculation is very approximate, moreover, it is used only for very well insulated brick houses, which also insulated attic and double glazed windows.But who of us house is insulated so perfect?Not at all.Therefore, when calculating the capacity of the boiler, consider home insulation, wall thickness, type of windows and the number of them.As you can see - the power calculation is not easy, so it is best to consult a specialist.
Choosing a gas boiler heating
Today the safest and cheapest form of fuel - main gas .If he had carried to your home, you can choose a gas boiler.Also, gas boiler does not require to store fuel, which is very convenient.
gas boiler heating is not so much affected by corrosion, and very quickly overgrown with soot, making it efficient and easy to use.With the right choice of the boiler efficiency it reaches 110%.
Gas boilers are of three types:
- Wall heating boiler;
- gas-fired boiler;
- Outdoor combi boiler.
Today, the most commonly used first two types of boilers, but the combi boiler is used infrequently.
Wall gas heating boilers
Wall boilers have gained widespread popularity thanks to their advantages.Here are some of them:
- Compact.Boilers up to 60 kW have a size of no more than the usual kitchen cabinets.Because of this they can be discreetly mounted in the bathroom, or do not oppress their presence on the kitchen wall.Also this small size put all the necessary attributes: pump, expansion tank, air vent, pressure gauge, etc.Thanks to these qualities, this type is sometimes called a "mini boiler room";
- Simplicity and ease of use ("Push and turn");
- inexpensive installation of the boiler.
Structurally, wall-mounted gas boilers are divided into two types - boiler with atmospheric gas burner and fan burner .
boiler with a gas burner - it is generally inexpensive boiler with a capacity of 20-35 kW.
boiler burner fan - a modern high-tech and highly efficient boiler, which will warm the house, and save money.Power - 24-100 kW.These boilers expensive floor and atmospheric.
On functional features these boilers are divided into two-circuit (with plate heat exchanger), and single-circuit (without it).
Double-circuit boilers have little power, and are designed for a single point of intake.For example - you included 2 baths 2 kitchens, in this case the water is lukewarm.Therefore, these boilers is used for single-family, mostly in suburban homes.
Single-boilers are small and medium power.For the preparation of hot water it needs indirect heating tank.In some models, the tank is already built-in.
Single and double-circuit boilers on the basis of exhaust gas and air are divided into two types - open and closed combustion chamber.
One popular wall boilers can be called Navien ACE turbo .This boiler Korean-made, which is designed according to modern technologies and meets all European quality standards.This boiler is wound unlike other quietly tolerate voltage drops and low pressure water and gas.The boiler is characterized by a long service life combined with economical gas consumption.
wound Boiler advantages:
- Stable operation at minimum pressure;
- efficiency - 92%;
- system frost protection;
- stainless steel heat exchanger;
- safe operation of the boiler.
pretty good reviews company has Vaillant , which manufactures wall and floor boilers of exceptional quality.One popular brand is the company's boilers atmoTEC pro VUW .This boiler, which has a built-in system of hot water.There is a standard option - 24-28 kW, and the version of "mini" - 20-24 kW.
Features boiler atmoTEC pro VUW:
- efficiency - 93%;
- Bus eBus;
- plate heat exchanger.
And another model of boilers, which have gained respect and popularity among our people - boiler Vitopend .This model also has its own distinctive features that set it apart in the market among the general crowd.First of all - it is a German manufacturer.As you know, Germany is famous for high quality goods, and is one of the most advanced countries.Consider the model of boiler Vitopend 100-W WH1D.The boiler has a capacity of 10.7 to 23 kW and from 13.2 to 29 kW.And, of course, mention the distinctive features of the boiler:
- High comfort cooking water;
- efficiency - 90%;
- Continuous performance 14 l / min;
- Electronic control with diagnostics;
- The unique design of the chimney, is excluded freezing even in severe frost.
Gas floor heating boilers
Floor boilers on the type of burner can be of two types - atmospheric and supercharged combined .
These boilers have an important advantage - almost silent operation.In addition, the burner in such boilers light but very strong.
atmospheric boiler efficiency is 87-90%.Operating pressure - 20 mbar, some (created for the Russian conditions) - 13 mbar.
supercharged boilers used with a removable fan gas burner.Efficiency in these boilers is 10% higher.Normally fan burners not included and sold separately.More noisy work and the high price - that's what gives it the previous boiler.
For example, let's look at the boiler one of the most popular models - gas boiler BAXI, to be exact - outdoor Turbofan gas boiler BAXI MAINFOUR 24.
gas boiler Baxi - an Italian brand is very well established in Russia and manyelsewhere.Economical, compact, very simple and effective to use - just a small part of the benefits.This type of boiler packed with all kinds of electronics, which makes life easier for the user of the product.
Many believe the gas boiler Baxi expensive, but let's see what we get when buying a boiler:
- 2-year warranty.Although the boiler and at the end of the guarantee will serve you faithfully for more than one year;
- modern high-tech system, which will make use of the pleasant pleasure;
- Manufacturer - Italy.It is not necessary to hide - a certain part of you pay for the brand, but in fact it's worth it.
- a lot of advantages in the characteristics of the boiler.
But Baxi boiler has a disadvantage.Since it is made in Italy, it is designed for normal water, which in our country is not there.This boiler does not tolerate "heavy" water, so maybe it will have to be cleaned more often (which is not very cheap).
Perhaps the company Buderus does not require any particular description.Most people know this company as a reliable and quality manufacturer of wall and floor heating boilers. boilers Buderus for several years held leading positions in the market, and that says a lot.We are closer look at the floor boilers Logano plus SB315 .
Mark these boilers is made with different capacity - 50, 70, 90, 115 kW.
very high utilization (109%) allows you to make huge savings of energy in your home.
very compact design of the boiler.At the top is the combustion chamber, located at the bottom of the condensation heating surface.
possibility of combining different tanks - water heaters and control systems Buderus.
iron or steel?
All floor boilers are divided into two types - from cast iron or steel heat exchanger.So what is the safer and more effective?
Cast iron boiler has a long life because virtually impossible to corrosion.However, it has a disadvantage - the fragility and heavy weight.A brittleness in turn might lead to microcracking.
steel cauldron lighter and stronger.However, improper use has a short life span.How to avoid it?Just make sure that the temperature dropped below the "dew point".
Application floor boilers for hot water
usually to buy an additional floor boilers tank indirect heating, but some models have built this tank (60-80 yrs.).But not everyone is quite this volume, besides the more indirect heating tank, the more comfortable hot water supply.
Boilers come in two versions - floor (120 l.) And wall (70-120 l.).
Electric boiler heating
Let's just look at the advantages of an electric boiler :
- Lightweight and compact;
- There is no need to keep the supply of fuel;
- No need for a chimney.
Electric boilers in Russia are divided into two types - domestic and import.Because they are so different from each other.
Domestic electric boilers
have a simple design, also used cheap parts, which reduces the cost and repair of boilers.
This type of boiler is fully suitable for use in the Russian context - are taken into account as the system pressure and harsh Russian winter.
mainly for domestic boilers is not possible to connect any third-party equipment (eg - the thermostat).
For example, take electric boiler Evan Russian production.This boiler is fairly simple to use, in addition, it is suitable for heating any premises: apartment, private house, office, etc.Since the boiler domestic production, its price is quite acceptable.Of course, the technical characteristics it is inferior to imported, but the price difference is quite large.About
cons of boiler few people have heard, but they do exist.Many complain of poor automatics - but we live in Russia.Also, people often talk about the low relay, which burns each year, but that's not all.
Imported electric boilers
import boilers are more complex and have advantages over domestic boilers:
- Slow start increases the service life;
- Possibility to connect the thermostat and programmer;
- LCD display;
- security group;
- Dry run protection.
- microprocessor (some boilers);
- Quiet operation.
efficiency of boilers is almost the same - 97-98%.
power calculation is performed as follows: Z = S / 10;Where Z - the boiler output in kW, S - area of the premises.
Installation of the boiler heating
Most manufacturers prohibit independent boilers installation , and it is logically understandable.We consider as an example of a gas boiler.So, if your experience ends at the facility outlet - it is better not to go.First, you can make it worse (especially when dealing with the gas).Secondly - risk losing a guarantee.But if you are confident that you can install yourself - read how to do it correctly.
Preparatory work to start - wash pipe from foreign particles (of which there is sufficient).The room temperature must range 5-35 + C and humidity - no less than 80%.The boiler is installed on a perfectly flat surface (you may have to carry out the alignment).Attach to the surface of non-combustible pad (2-3 mm.).Check grounding, stabilizer, wiring, circuit breaker.
floor boilers for preparing a good foundation (concrete floor).For better fastening make "pocket".
Now connect the boiler to the water system.To begin, shut off the water supply.Then connect the boiler to the water supply with a special attachment.
Return connects bottom and hot water - from the top.
pipes should have a slope (less than 0.5 cm per meter).
installed on the pipeline valves.
After installation be sure to check all joints for leaks.
Next comes the connection of the boiler to the chimney and gas pipelines.
connection to the gas mains may only be employees of the gas service.
Today, you are not safe from power surges or power outages, but you can use to connect an uninterruptible power supply gas boilers.
