What are Buderus boilers?
Condensing
Condensing type devices were once an innovation in the field of heating technology. They are much more efficient than traditional heaters. This is due to the use of energy, which in conventional designs simply flies into the pipe – along with the products of combustion. The principle of operation of condensation modifications is based on the use of energy losses to heat the coolant. Thanks to the energy of the burned gases, it is possible to reduce fuel consumption. At the same time, the emission of harmful substances into the environment is also reduced. This is the most economical and energy efficient option.
Wall mounted
Mounted versions are especially widely used for autonomous heating of apartments. Having a small size, wall-mounted boilers are in no way inferior to their floor counterparts in terms of heat output and functionality. They may have one or two circuits. Their power is usually small – in the range of 7,8-28 kW. But there are also more powerful devices – for large houses and cottages. All wall-mounted versions are equipped with a circulation pump, an expansion tank, a pressure gauge, a thermometer, an automatic control system, an efficient heat exchanger, a burner and other elements necessary for a gas heating device. The main advantages are compactness and lower cost compared to floor versions.
Outdoor
Floor standing versions can have atmospheric or forced draft burners. The heat exchanger is usually cast iron. Rarely steel. There are universal modifications – they can use any fuel (gas, pellets, fuel oil, diesel fuel, rapeseed oil). Plus – independence from one type of fuel.
The power of floor-standing devices is greater than that of wall-mounted counterparts – 52-000 watts. Thanks to noise-absorbing devices, they practically do not make noise. More pluses:
- Smooth adjustment of water temperature.
- You can install additional devices – to increase functionality.
- You can connect a hot water tank up to 200 liters.
- They continue to work if the gas pressure drops to 10 mbar.
- Intuitive controls.
- Reconfiguration of burners for an alternative type of fuel.
Mounting Features
Gas heaters are easy to install. The connection and the first start-up must be carried out by gas service specialists or workers with a special permit – this is exactly what the instructions for users prescribe. Self-installation is prohibited. You should not try to connect and start the boiler yourself – the gas workers will never give permission to operate it. Violation of this rule will void the warranty. Setting up and maintaining the equipment is also the responsibility of specialists – the user can fix only the most minor problems on his own. But there are requirements that it is useful for owners of gas equipment to know about:
- The connection is made using corrugated pipes approved for use by Gostekhnadzor.
- Installation must be carried out in a room that complies with SNiP and PPB.
- When making a connection to the chimney, the scheme “one device to one pipe” must be followed. For cascade connection, an upright coaxial chimney is required.
- The setup and the first start-up are carried out together with the gas service inspector – he puts the appropriate marks in the technical documentation.
Even if you know how to connect and how to set up gas equipment, it is strictly forbidden to do it yourself.
Design features
If a single-circuit boiler is designed exclusively for heating, then a double-circuit boiler is also capable of providing users with hot water. Devices with two circuits can be:
- Flowing. Water heating occurs in flow mode. The equipment is smaller, and the water is heated immediately when the tap is opened.
- Cumulative. There is a boiler – a built-in container for heating water. This is a more economical option.
One of the most popular models of the German brand is Logomax u072 183a. These are real mini-boilers – energy efficient and safe. A high level of security is provided by built-in sensors. If, for example, the burner goes out, the gas supply will be automatically stopped. There is an automatic system that maintains temperature stability. Water filtration is also provided.
How to connect a boiler?
For strapping, only branded components and equipment compatible with Buderus heaters are used. To facilitate the connection of the BKN – an indirect heating boiler, there are valves in single-circuit versions. The supply and return are connected in accordance with the connection diagram specified in the operating instructions. You can connect containers with a volume of 60, 80, 100 and 120 liters. Moreover, it is allowed to do this even in winter – there is no need to turn off the heating to connect the BKN.
What should be the room?
Regardless of what brand the equipment is installed and who its manufacturer is, the same requirements are imposed on the premises:
- Need natural ventilation.
- The minimum height is 2,2 m.
- Area – from 12 m²
- Doors should not have a threshold. The gap between the door leaf and the floor surface is 1-2 cm.
For turbocharged options, a reduction in area to 8 m² is allowed.
How much does a Buderus boiler cost?
The price of German gas heating equipment was significantly reduced due to the location of production facilities in Russia. For example, the Logamax U072K wall-mounted device costs today in the range of 30-35 rubles. Outdoor model Logano G000 WS RU – about 124 rubles. Such prices and brand recognition predetermined the popularity of Buderus products among Russian consumers.

Reviews
Logamax U072-24K: Robert M., Kungur
I heat 230 square meters. Since the brand is strong, the opportunity to buy an inexpensive option pleased. The assembly is good, the temperature keeps. But there are serious disadvantages – you need a voltage stabilizer, as it is demanding on the network. The menu is not easy to figure out. And most importantly – the feed tap. It’s plastic for some reason. I think this is not saving on material, but a special move – after 2-3 years it breaks down and you are offered to change it. And a new one costs 3-4 rubles. It turns out – they make a problem node, then to make money on it?
Logamax U042: Victoria A., Pavlovo
Warming the house for the second season. Since installation and configuration, nothing has been touched or changed. It works in parallel for heating water – heats it quickly and in large volumes. Takes up minimal space – hangs on the wall without disturbing anyone. Operation is virtually silent. Weighs about 40 kg. Reliable and safe, this is not scary to have in the apartment. All gases are thrown out into the street, and air comes from there – a model with a closed firebox is ideal for an apartment.
