Use of the combined boilers of heating is justified from the economic and practical point of view as this unit is capable to work from several types of fuel at once. The efficiency from operation of the combined boilers will be reached only on condition of its correct mounting and installation.
Mounting and installation of the combined boilers
The boiler is the main component of all heating services. Before beginning installation of boiler and other elements of system, it is necessary to develop the plan of future system and to calculate amount of the materials completing and also power and type of boiler. Each part is important: condition of walls and their thermal insulation, height of ceilings, wiring layout of pipes and location of boiler.
As practice shows, in the economic plan gas boilers of heating are the most favorable, but there is not always possible connection to the central gas pipe-line. The combined boiler which at the same time can work at different types of fuel becomes the solution of this problem. This unit is installed so that transition just seeing fuel to another was carried out quickly and smoothly.
Stages of installation of boilers
Installation of the combined boiler is possible only on floor as dimensions and weight do not allow to fix it on wall. After the installation site is chosen, it is necessary to organize flue. It is very important to provide good draft as units burn coal, gas, the electric power, liquid fuel. Power of these models reaches 100 kW. At the high efficiency and big power it is possible to heat owner-occupied dwellings and the commercial areas. Installation of the combined coal-gas boiler demands availability of special permission. Upon transition just seeing fuel to another one torch is dismantled then another is established. Before connection of boiler to the general heating services carry out washing for removal of pollution. Further the boiler is connected with flue and the gas pipeline. The next stage is connection in PVS and to the pipeline. Also connection of power supply is carried out. The combined boilers are equipped with several exits which provide connection of heating services and hot-water supply and also heat-insulated floor, system winter garden and others. After installation of boiler and to connection of all elements in uniform heating system, it is necessary to execute hydraulic test of the equipment and adjustment of system of burning. It is worth to remember that installation of the combined boiler of heating means the certain boiler house where the boiler and tanks for liquid fuel will be located.
