Gas boiler with an open combustion chamber How to convert a gas boiler to liquefied gas
Types
There are different modifications of Buderus wall-mounted boilers.
By the number of contours:
- Single-circuit. Provide only heating of the heating agent for the heating circuit.
- Double-circuit. At the same time, they are capable of preparing hot water supply and heating the coolant for the heating system.
By type of combustion chamber:
- Atmospheric (open)... The air required for the combustion process is taken directly from the room where the boiler is installed. The removal of smoke and other combustion products is carried out using the natural draft of the furnace type.
- Turbocharged (closed)... The air is taken from outside and enters the boiler through the external pipe of the coaxial chimney. For this, a turbocharger fan is used, which at the same time ensures the removal of smoke.
For residential premises, it is more convenient to use turbocharged models, since the natural thrust is unstable and can be directed in the opposite direction by a strong gust of wind or a draft in the room.
By the type of heat transfer:
- Convection... The traditional scheme of heating the coolant in the burner flame was used without additional procedures.
- Condensing... A technique that has appeared relatively recently. Preheating of the liquid is applied using thermal energy obtained by condensing water vapor from the exhaust smoke. The prepared heat carrier does not require intensive heating, which allows to reduce gas consumption and soften the operating mode of the heater and heat exchanger. In total, this gives a high efficiency (up to 108%, although this method of calculation is not correct and is a common marketing ploy), gas savings and an increase in the life of the heat exchanger.
IMPORTANT!
Condensing models are capable of fully functioning only on low-temperature systems. If the operating conditions do not allow the use of such modes, the purchase of a condensing boiler will become impractical.

Gas boiler Rating of the best.
To begin with, let's define the concepts. Actually, we choose from only two main types of design solutions. A gas boiler is either single-circuit or double-circuit. What does this mean and which gas boiler is better? Let's figure it out. Ultimately, our choice should be based on the intended use of the device. Many people mistakenly assume that a double-circuit boiler is when one circuit heats, for example, the first floor, and the second circuit heats the second floor. In fact, not everything is so simple.
Single-circuit or double-circuit
The single-circuit version is used for its intended purpose. Purchased for the purpose of equipping the heating system. Nothing else is required from the unit. To comfortably spend the winter, you need the oven itself, a circulation pump, radiators, piping, a little gas, and it's done. Warmth and comfort will be provided in full.
A double-circuit unit, a kind, one might say a combine. In addition to the heating function, it combines a gas flowing water heater in itself. Simply put, it is a gas water heater and a boiler in one housing. The task is to heat the house? - no problem, everything works like a clock. But what happens when one of the household members decides to use the shower? The priority of any double-circuit device, as soon as the consumer has opened the hot water tap, instantly switch to the gas water heater mode.
Modern automation is responsible for this. After the consumer has finished the water procedures, the boiler returns to its main purpose. The double-circuit unit is becoming more widespread, especially since the manufacturer does not increase the price for two circuits linearly. The price, in comparison with the single-circuit version, of course increases, but within adequate limits.
Floor-standing or wall-mounted
We think everything is much simpler and clearer here. The name speaks for itself.
Once it is floor-standing, then we install it on the floor. Here the manufacturer does not particularly limit himself either in size or in technical solutions. Trying to offer a wider range of choices with more power. Variants of floor devices imply the arrangement of a separate room, and they heat serious, large country houses with an area of up to 800 square meters. With high efficiency, with various options for gas burners, combustion chambers, atmospheric, turbocharged and so on, in general, as they say: any whim for your money.
A wall-mounted heater is a “thinner” tool and requires a low weight, small overall dimensions, and at the same time with functionality like a full-fledged floor counterpart. Most manufacturers offer the device no more than 35 kilowatts of power. They are hung on the wall, are small in size, crammed with all sorts of levels of protection. Often they use the same components from reputable suppliers. For example, the legendary SIT gas valve of the Italian brand, we meet quite often in many models, and the main struggle for the consumer unfolds at the level of design solutions.
What series and models belong to the wall
Wall-hung boilers Buderus are represented by one large line of Logamax, which consists of 4 series:
- Buderus Logamax U042 / U044... Double-circuit plants with a capacity of 24 kW. Equipped with a bithermal heat exchanger, which allows heating both the coolant and hot water at the same time. There are models with a closed (042) and an open combustion chamber (044).
- U052 / U054 K... Single and double-circuit boilers with open (054) and closed (052) combustion chambers. For double-circuit models, the designation contains the letter "K" (combined). Available in two models, 24 and 28 kW.
- U052 T / U054 T... 24 kW model with open or closed combustion chamber. A special feature is the presence of a storage tank for hot water supply of 48 liters, which makes it possible to meet high needs for hot water.
- U072 ... The most popular series of turbocharged boilers with a capacity of 12,, and kW. Available in single and dual circuit models. The high demand is due to the relatively low cost of boilers. Equipped with two heat exchangers - primary (for the heating agent) and secondary (for hot water supply). The most popular are boilers with a capacity of 24 and 35 kW, producing up to 12 and 16 liters of hot water per minute, respectively. They are capable of heating 240 and 350 m2 of residential, public or commercial space.
When choosing a boiler, its characteristics should be compared with the size of the room and the family's need for hot water supply. The manufacturer provides a choice for any conditions, which allows you to get the best option.
Single-circuit floor-standing gas boiler for heating a private house
We will start the review with a single-circuit proposal, such models are in demand where there is no need for hot water supply, and the purpose of the purchase is to equip the heating system at reasonable prices.

Protherm Medved 50 Disadvantages
Pleasure for the owner of Protherm Medved 50 KLZ and potential buyers - it brings a surprisingly acceptable cost of the device. Boiler and boiler are all assembled and at a bargain price. To the disadvantages of the boiler, taking into account customer reviews, we attribute the forced pumping of the hydraulic tank three to four months after starting the boiler.
The next unpleasant moment may be a breakdown of the boiler loading pump. As evidenced by the reviews of the owners, sometimes there is a problem in the thrust sensor, installing the sensor closer to the exit helps to deal with it.
In general, Protherm Medved 50 KLZ is noted as an excellent gas boiler for private houses, but still, if space permits, then individual elements are preferable. It is always easier to repair the boiler from the boiler separately, and the replacement of spare parts, for example, at the boiler and waiting for them after ordering, will not cause the entire system to stop.

For top-level equipment, this slightly and significantly increases the demand and demand among users..
When planning a purchase, you need to check with your regional representative the cost of the units and find out the amount of additional costs (warranty agreement, cost of additional equipment, etc.).
IMPORTANT!
An attempt to save money on concluding a warranty agreement will result in even greater costs for repairs or maintenance of the boiler.
Selection Tips
Gas boilers "Buderus" can be wall-mounted or floor-standing. The former are optimal for areas up to 350 m2. Such devices are distinguished by attractive design, compactness and ease of installation. Depending on the model, the exhaust gases can be discharged through a chimney or a small coaxial pipe. The latter option is safer and cheaper, because the combustion products will be removed outside the house using a simple fan. When installing such a unit, there are no additional requirements for the ventilation system.
Wall-mounted gas boilers "Buderus" can have piezo ignition, which is activated by a special button. You can choose a model with automatic electronic ignition. The latter is convenient, because in case of power outages, the boiler turns on itself as soon as the electricity comes through the wires. But with piezo ignition, the owner must turn on the unit.
In large rooms, floor-standing boilers are usually installed. They are distinguished by an impressive mass, so they cannot be hung on the wall. A foundation is often mounted under them. Choosing a floor-standing boiler, you will have to tilt your choice towards devices with a forced or atmospheric burner. The latter is cheaper, simpler and quiet. The first is characterized by a higher efficiency, but also an impressive cost. The atmospheric burner is included, but the pressurized burner will have to be purchased separately.
When considering gas boilers "Buderus", you should pay attention to details that increase the safety of operation, but entail an increase in price. Among these options are:
- thermostat to turn off the boiler;
- flame sensor;
- traction control sensor;
- blocking the boiler.
As for the flame detector, the element is necessary to shut off the fuel supply if the flame goes out. When you turn off the gas, you need a blocker, so it's better to purchase a model with this function. Pay attention also to the thermostat, it is designed to turn off the unit when the water temperature rises to the emergency level.
