Best Garden Product Ratings

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

When the gas main runs far from the village, diesel boilers help to create a comfortable microclimate in the house. They allow you to organize a heating system with minimal interference from the residents of the house. The advantages of the liquid heating method include economical consumption and the ability to automate the operation of the device. A wide range of domestic and foreign models is presented in the Russian trade network. Our experts will help you choose the best diesel boiler, taking into account the terrain and size of the house.

Diesel boiler selection criteria

Boiler type. Modern diesel boilers differ in the type of fuel that can be used to generate heat energy.

  1. An oil-fired boiler most often runs only on diesel fuel, sometimes it can efficiently burn fuel oil or waste oil. These devices have a narrow focus, they are affordable and easy to maintain.
  2. Combined boilers can operate on several types of fuel. Such a device is suitable for residents of the province, where there is an opportunity to stock up on inexpensive firewood or coal. Some models run on LPG or natural gas. Combined devices allow you to establish uninterrupted heating using several sources of heat energy.

The number of contours. Diesel boilers differ in the number of heating circuits.

  1. Single-circuit models are designed exclusively for heating the coolant that circulates in the heating system. But such devices cannot heat water.
  2. A double-circuit boiler not only heats the room, but also solves the problem with hot water.
  3. Occasionally, you can find multi-circuit boilers on the market. They constructively have more than two contours. In addition to heating the coolant and water, the device can provide heat to the floor heating circuit.

Energy independence. Diesel boilers can operate autonomously or with feeding the control system from the mains.

  1. For residents of settlements, where power outages are frequent, energy independence will be an important characteristic of a diesel boiler. This means that the diesel fuel will be converted into heat energy without being connected to the mains.
  2. Among the heating devices, there are models that are connected to a single-phase network (220 V). But experts recommend buying additional stabilizers in order to prevent the failure of the electronics during voltage surges.
  3. There are also devices that operate on a three-phase electrical network (380 V). Some of them can also be connected to a single-phase line.

Control method. There are several ways to control modern diesel boilers.

  1. Boilers with a mechanical control system are distinguished by their ease of maintenance and repair. Mechanical regulators are usually installed in non-volatile boilers.
  2. The electronically controlled models are comfortable to operate. Modern controllers make it possible to program the boiler operation mode without requiring the constant presence of a person, and to economically consume fuel.

Thermal power. Each diesel boiler has a maximum heating capacity. Thanks to this indicator, you can choose the right device, taking into account the size of the house. It is generally accepted that for heating 10 sq. m of housing requires 1 kW of heat. But this formula can only be used when purchasing boilers with high efficiency (from 90%). Otherwise, it is better to purchase a heating device with a heat output exceeding the calculated value by 10-20%.

We have selected 11 best diesel boilers for review. All of them are sold in stores in our country. When allocating seats, the editorial board of the magazine relied on the opinion of the expert community, taking into account the reviews of Russian consumers.
