What to Consider Before Buying a Gas geyser

When setting up a private heating system, the main issue is always the right choice of gas geyser because it will depend on your family’s comfort level in the future. Models of geysers are very many, functionality at all different and the purpose too. Therefore, if you decide to buy a gas geyser heating, it is worth studying the main features of this equipment, which for you prepared experts of our online store Vencon.

Before you go to the store or open a directory of the site, you should find out the main points to facilitate your further choice. Decide for yourself what functionality you need and what you want to get at the end – high efficiency, usability, or maximum savings. Please make a list of the main requirements; it will help you quickly decide on the boiler model.


A variety of boiler equipment on fuel combustion efficiency

The energy efficiency of boiler equipment depends on the amount of money you will pay for gas consumption at the end of the month, so choosing one or another type of unit should be treated with maximum attention.

According to the “boiler type” option, you can divide geysers into species that will directly affect the level of energy efficiency:

In condensation devices, heat exchanger heating is carried out by combustion of gas and heat transfer from smoke gases and heat from vapor condensation in smoke gases. Such heat exchange is possible because of the special design of the heat exchanger.

In the turbocharged gas geyser, gas condensation does not occur, so the energy on healing comes only from the burning of gas masses.

In the convection gas geyser, the heat transfer processes are similar to turbocharged; the difference is the absence of a turbine, which increases the efficiency of the equipment.

The parapet units on the principle of heating are similar to convection units. The design allows them to be operated as a radiator.

Before choosing a gas geyser, look closely at the condensation heating devices – they are more energy-efficient (up to 20%) compared to models of other types.


Contours – what influences their number

The geysers are two-contour and with one working circuit. The difference between the units is only one thing: single-contours only heat the room, and devices with multiple contours can also provide water heating. A striking example is gas geysers with a built-in boiler.

The choice of the principle of work may depend on various factors. For example, to save money, some owners use the boiler only to heat the dwelling, and it is more profitable for them to get water from the central system of GWS.


How fuel is set on fire in geysers

How fuel is set on fire in geysers

There are two main types of gas ignition:

  • Piezorozzhig.
  • Electronic.

The pie in the boiler is arranged like an arson system in a lighter – on the body of the boiler is pressed a button, causing a spark, which in turn sets fuel on fire.

The electronic ignition is triggered automatically when the unit is launched. You don’t need to press any buttons to set the gas to ignite the gas – the system controls everything. The weak point of this type of ignition is dependence on the electricity grid.


Traction and combustion chambers

This parameter determines how carbon dioxide (burning waste) is removed from the system. Among the many models, there are geysers with forced traction and units with natural traction. The latter refers to the classic version, which is installed in well-ventilated rooms to connect to the chimney. These geysers have an open-type working chamber.

Forced removal of gas waste occurs through a built-in fan that drives out the smoke through a special drain. If you are puzzled and choose a boiler gas by the type of thrust, it is worth starting from where you live. If the ventilation in your home is good, and there is a chimney, you can safely install equipment with natural traction. In such geysers installed a working chamber closed type, which allows the use of the boiler in places where the traction is disturbed.


Where to install the boiler – choose a gas geyser in the way of installation

choose a gas geyser in the way of installation

By way of installation to choose simple, there are only two varieties:

  • Wall (up to 100 kW).
  • Floor structures of great power.

Deciding which gas geyser to choose, you need to know exactly what kind of power you need because the wall can install a device with a capacity of up to 100 kW. Geysers with power levels above 100 kW are usually heavier and will not fit in weight. The floor-type units are more powerful and have larger dimensions, but there are exceptions.


Modern heating control system

gas geysers work with dangerous fuel, so they need increased attention from the user. A malfunction of the device can lead to fatal consequences (for example, an explosion). Therefore, the boiler system should work according to a detailed mechanism.

It is impossible to control such a system manually, so the machines use automatic systems that:

  • Provide fuel on the fire.
  • Support the combustion process and control the dosage of fuel in the boiler.
  • Control the level of traction.
  • Include the supply of fuel when the temperature threshold of the coolant is lowered.
  • Turn off the fuel supply at maximum heat.

Also, automation is responsible for your safety – the slightest interruption of the system will be a signal to stop gas flow.

According to the principle of operation, the automatic control system in the boiler can be electronic or mechanical. The classic mechanical control of the gas geyser takes place without electricity – this system is considered energy independent. It is in such units you can meet.

The mechanical control unit works only in three modes: burning fuse, fuel supply mode, complete shutdown mode. The amount of gas that is fed in fuel supply mode is controlled by the user manually. Simultaneously, there may be minor errors in the temperature setting due to the specifics of the mechanical nodes. Unlike electronic control of a gas geyser, the mechanical system is rougher, but it is much simpler in its principle of operation.

The electronic system does not need to choose the mode of operation manually; all control temperature sensors determine when to open or close the gas supply. It is enough to make data about the desired temperature mode in the program and forget about this issue for a long time. Some manufacturers produce gas geysers with Wi-Fi control; this makes them very convenient for large farms or factories.

Before you choose a gas geyser, you need to highlight the main advantages of each control system. The advantages of mechanical control include its cheapness and independence from electricity. If you’re looking for an inexpensive gas geyser with simple functionality, the mechanics model is perfect for you.

Electronic management is, of course, the highest level of heating equipment. Such units control the microclimate in the room with great precision. Although electronics, unlike mechanics, depend on electricity, at the moment, the problem is easily solved with a smooth power device.


What fuel is used in gas geysers

You can find units that use two types of fuel:

Propane butane is used as fuel in liquefied natural gas geysers. Unlike natural gas, this product is easily transported. Today, there are still settlements and other settlements to which there is no gas main. The use of liquefied fuel geysers for residents of remote settlements is the only option to provide a comfortable microclimate in their home.

Liquefied fuel geysers are strictly prohibited from being used in conventional gas pipeline systems without refurbishment. They have a different design. Simultaneously, some models can be converted from natural gas to liquefied gas and vice versa.


Choosing a gas geyser to heat the house on the properties of the heating element

It is the heat exchanger responsible for heating the circulating liquid, so the energy efficiency of the entire system depends on it.

All existing devices on the material of the heat exchange element can be divided into 5 types:

Among the popular can include units with steel heat exchangers. This is due to the cheapness of the material and its good plasticity. But because of the poor corrosion resistance, such heat exchangers require periodic replacement. Also, the metal device has a large volume and weight, respectively, on its heating to spend more valuable energy.

Geysers with aluminum heat exchangers are often called geysers of the future. Aluminum alloys are not corrosion-free and are capable of operating in an aggressive environment. They have good heat exchange properties, have increased durability of the design.

Gas geysers with copper heat exchangers are mostly of small power. This is because copper is prone to rapid burnout at very high temperatures. But because of its unique heat exchange properties, it is still used in thermal equipment with certain temperature ranges of work.

Stainless steel is a good option for conventional steel because stainless steel heat exchangers are completely resistant to corrosion. They are not much different from steel heaters at a price, but their lifespan is many times longer.

Gas geysers with cast-iron heat exchangers are very durable. The material is almost not affected by corrosion, but many buyers refuse geysers with cast-iron heat exchangers because of the complexity of the operation. Cast iron is susceptible to temperature changes.


How smoke from the system is mouthed in gas geysers

On this basis, it is possible to distinguish two varieties: chimney and smokeless boiler (parapet or turbocharged).

A chimney gas geyser produces smoke exhaust through an atmospheric chimney. It creates a natural craving. Such devices usually involve an open camera.

In a parapet, turbocharged, or a smokeless boiler, combustion products are withdrawn through a special channel – a coaxial chimney. These are geysers with forced traction.


geysers with additional equipment

In addition to the classic models on the market, there are also more functional gas geysers. For example, you can find a model of a gas geyser with a built-in circulation pump, the presence of which allows you not to install the pump in the system separately.

It is also worth considering geysers with a built-in expansion tank. These units are installed in heating systems, where frequent pressure swings are possible. The additional tank acts as a compensator and takes on all the loads.

Before choosing a gas geyser for a private house, make sure that it has a three-way GWS valve. It ensures an even distribution of fluid flows through the heating system. All gas geysers of the new standard are equipped with such a valve.
