Rating of the best wall-mounted single-circuit gas boilers
In the gasified regions of the country, gas boilers are recognized as efficient and economical heat sources. When arranging an autonomous heating system in a private house or in the country, it is quite enough to install an apparatus with one heating circuit, designed specifically for heating the room.
There are two main designs of gas boilers - single and double-circuit. Disputes about which option is better still persist.
How to calculate the power?
Calculating power according to scientific methods is rather complicated. The heat loss of the building is determined, the heat circuit is calculated, the effects of openings or other openings are taken into account.
The process is difficult even for professionals, not to mention untrained people. Therefore, a simple and fairly correct technique is usually used. One kilowatt of thermal power is capable of heating an area of 10 sq. m.
Therefore, to determine the power of the boiler, you need to divide the area of the room by 10. For example, for 180 sq m, you need 18 kW of power.
Attention! Boilers that are too weak or too powerful should not be chosen. In this case, the stock works to the detriment - the unit works in the wrong mode and breaks down faster.
Single-circuit boilers rating
MORA-TOP Meteor Plus PK24ST
A well-known Czech manufacturer of heating equipment, MORA-TOP produces a wide range of gas boilers. The Meteor Plus PK24ST model is an atmospheric unit that needs to be connected to a classic type chimney.
The power of the boiler is 23 kW, which allows heating rooms up to 230 sq. M. Wall mounting facilitates easy access to the connection pipes and simplifies maintenance of the unit.
Main characteristics:
- coolant temperature - 30-90 °;
- system pressure - up to 3 bar;
- gas consumption - 2.67 m3 / hour;
- dimensions - 400x750x380 mm;
- weight - 31 kg.
The boiler is equipped with multi-stage protection against external influences, overheating, reverse draft and other undesirable conditions.
It is possible to connect an external control and a storage boiler for hot water supply.
Buderus Logamax U072-18
Buderus is part of the Bosh holding, which significantly expands its capabilities. Heating boilers of this brand are distinguished by their reliability and high quality combined with relatively low prices.
The Buderus Logamax U072-18 model, thanks to its 18 kW power, is capable of heating 180 sq m of residential or public space. The boiler has a copper heat exchanger, a closed-type burner, multi-stage protection against all overloads or external influences.
Main characteristics:
- coolant temperature - 40-82 °;
- system pressure - up to 3 bar;
- gas consumption - 2.1 m3 / h;
- dimensions - 400x700x299 mm;
- weight - 34 kg.
To create a full-fledged DHW line, an external boiler must be connected. For this, the boiler already has a 3-way valve and a circulation pump. The capacity of the expansion tank is 8 liters, which makes it possible to overcome temperature fluctuations in the volume of the coolant.
BAXI LUNA-3 1.310 Fi
The Italian company BAXI is known as a manufacturer of high-quality and durable heating equipment. Currently, the factories of this company are distributed throughout Europe, and the head office is located in the Netherlands.
The double-circuit wall-mounted boiler BAXI LUNA-3 1.310 Fi has a power of 31 kW, designed for maintenance of an area of 310 sq.m. The copper heat exchanger allows for maximum heat transfer efficiency. The closed type burner eliminates flame blowouts due to sudden gusts of wind or strong drafts.
Main characteristics:
- coolant temperature - 30-85 °;
- system pressure - up to 3 bar;
- gas consumption - 3.52 m3 / h;
- dimensions - 450x763x345 mm;
- weight - 38 kg.
The manufacturer sets a 10-year service life for its products, provided that all requirements for operation and timely maintenance are met.
Protherm Panther 25 KTO (2015)
Protherm is a subsidiary of the Vaillant Group.It was formed as a special unit for the production of low-cost budget-class gas boilers.
However, the existing requirements and strict European standards have done their job - Protherm products are not inferior in quality to the products of the parent company. The Protherm Panther 25 KTO boiler (2015) has a capacity of 25 kW and is capable of heating 250 sq.m. useful area.
Main characteristics:
- coolant temperature - 30-85 °;
- system pressure - up to 3 bar;
- gas consumption - 2.8 m3 / hour;
- dimensions - 440x800x338 mm;
- weight - 41 kg.
Wall mounted gas boilers represent a "cat" line, where all series have corresponding names - Lynx, Panther, Jaguar, etc..
Viessmann Vitopend 100-W A1HB002
A sample of a gas boiler from the leader of the European heating industry - the Viessmann company. Firm policy does not consider the possibility of reducing the quality or reliability of its products.
The Vitopend 100-W A1HB002 model clearly demonstrates the approach of the company's engineers to the creation of heating units. Boiler with closed burner, power 29.9 kW (for heating 300 sq.m. area).
Main characteristics:
- coolant temperature - 40-80 °;
- system pressure - up to 3 bar;
- gas consumption - 3.47 m3 / hour;
- dimensions - 450x725x360 mm;
- weight - 38 kg.
Experts note that the gas consumption is too large for such a capacity. However, when an external water heater is connected, the fuel consumption practically does not increase.
This makes the boiler a good option, capable of providing the room not only with heat, but also with hot water supply when an additional unit is connected.
Single-circuit boilers are capable of performing all functions, you just need to connect additional devices. Many users do not know this, purchasing double-circuit units without an accurate understanding of their needs.
You need to have an idea of the amount of hot water supply needed for your family in order to provide her with complete comfort.
