Universal heating boilers for private homes: review of the best models and reviews

Heating boilers are primarily characterized by structural and operational parameters. At the same time, the group of performance indicators depends to a large extent on the fuel used. Liquid, gas and solid fuels assume their special qualities, which manifest themselves during the maintenance of the unit. To use the advantages of various combustible materials to the maximum, many homeowners switch to combined or universal boilers that are multifunctional. With the help of such equipment, the most suitable type of fuel can be used, focusing on the season or heating requirements.

Features of combined boilers

The main feature and advantage of the units of this type is that the user can use another one - more affordable if there is a shortage of one type of fuel. They are also profitable from a financial point of view. For example, electric models are considered to be the most expensive in operation, and gas mixtures, on the other hand, require the least expenditure. It is important to consider that universal boilers can support the use of an incomplete range of fuels. So, there are models that work only from solid fuel fuels or electricity, or modifications that are fueled by diesel fuel and gas - to choose from. But also multi-fuel devices are also common. In both cases, the boilers support one main type of fuel by means of the installed main burner, and in addition the user can purchase special integrated units for working with alternative fuel.

Comments about Atmos model

Atmos, with examples of its DC 32SP and DC EP series, demonstrates the central direction of technological development in the segment, which has given a new impetus to the development of alternative heating designs. This equipment operates on the principle of generator gasification, which is supplemented by the function of the burner for biofuel. The peculiarity of this direction is caused by the use of pellets - a relatively new type of fuel, which gives a high level of energy efficiency. In addition, Atmos universal boilers can work on natural gas and on fuel oil. Unlike most combined models, such units also eliminate the need for different burners. Multidimensionality of the function is provided due to the presence in the device of several chambers intended for different groups of fuel filler.

Reviews about the model Baxi

In the Roca line of the Spanish manufacturer, the P-30 model is introduced, with a slant in a different concept. The developers used light gray cast iron, thanks to which a high thermal insulation was achieved. There are several modifications of this unit, which differ in power - from 23 to 52 kW. The choice in favor of this or that version should be done proceeding from the place where it is planned to use this universal boiler. At home, it is quite possible to operate even a medium-sized installation as the main source of heating. In a small apartment is more suitable initial modification of the P-30. Boilers are supplied mainly with solid fuel, but as an alternative, it is also possible to use liquid fuel - diesel or diesel fuel.

Reviews about the model Jaspi Tupla

This model can be considered not only as a universal boiler in terms of the use of different types of fuel, but also as a multifunctional installation in terms of tasks to be solved. In addition to the basic function of heating, this equipment solves the problems of hot water supply. Other combined models are also known for the same qualities, but in this modification the operating modes are optimized for household needs. First, this universal boiler is endowed with a wide range of safety systems, since working with gas requires a high level of reliability. Secondly, the ergonomics of operating modes management provokes positive feedback not only in terms of the performance of electronics, but also with regard to structural elements.

Model Reviews Buderus

Buderus is well known to specialists engaged in engineering and utility equipment. In this case, it is worth considering a non-standard solution Logano S121-2. The universality of the model can be called conditional, since the unit is still mainly focused on working with solid fuels and, above all, with firewood. But the boiler has two essential features. First of all, this is the possibility of interfacing with other heating equipment, which can work on any fuel raw materials. The second noteworthy aspect is connected with the fact that the universal solid fuel boilers from the Logano series operate on the pyrolysis principle. In other words, the recycling of the combustion products itself is envisaged, which reduces the amount of harmful emissions and increases the heat transfer of the equipment.

Positive feedback about universal boilers

As noted by experienced users of such boilers, they practically do not lose to similar mono-fuel units in terms of energy efficiency, but at the same time they retain the possibility of applying the optimum fuel in specific conditions. Obviously, the absence of restrictions on the choice of a particular combustible material also ensures a reduction in the cost of money for operation. In addition, universal heating boilers simply because of the complexity of their device should be endowed with additional security systems. Accordingly, and practice of using demonstrates a high degree of reliability of models of this type.

Negative feedback

If in the process of operation the user has the opportunity to plan financial costs for the purchase of fuel with high savings, then the purchase of such a boiler in any case will cost more by 20-30%. Again, technological and structural complexity inevitably contributes to the price increase. The second serious drawback, which users note, is associated with maintenance and basic content. Unlike mono-fuel assemblies, universal boilers assume a wider range of preventive measures that their operator must perform. This includes cleaning the cameras with burners, and checking the working components, as well as testing the circuits that work under different loads depending on the fuel used.

Conclusion

The trend of transition from traditional boilers to universal boilers was formed against the background of the popularization of biofuel. Those same pellets can not be used for conventional firewood for solid fuel. Therefore, there were special units designed for biofuel. And on their background, in turn, the idea of combining different combustion systems in one design arose. In its present form, the universal boiler of a private house is capable of providing both full heating and hot water services. In this case, do not think that the variety of available fuel for use greatly simplifies the process of operation. Of course, thanks to the universality, you can expect substantial savings. But it will become possible only if the appropriate operating modes of the boiler are used in a competent and timely manner.
