The modern autonomous systems of utilities allow to provide the country house which is far from the centralized heat and water supply, all usual and necessary comfort. Independent operation of heating services can be adjusted easily by means of boilers, running on gas, electricity, liquid fuel.
Types of the used fuel
The most economic option – the autonomous system of hot-water heating, running on gas. In this case water heats up by means of the boiler connected to the system of gazosnazheniye and via the pump comes to the radiators located in rooms of the house and connected in the closed contour. Finishing cycle, the cooled-down heat carrier – water - comes again to holding tank and again heats up.
Heating temperature can be regulated manually or automatically, the system will support its set value. At absence on your site of the main gas supply it is possible to buy the boiler using liquefied gas. The design of the majority of gas boilers provides both that, and another options, replaceable nozzles are included in the delivery package. Boilers on liquefied gas for which storage the big capacity is necessary and for giving – the special equipment, cost much enough, besides, their installation demands additional coordination in local bodies of technical supervision.
Operation of the boilers using solid fuel – firewood, peat or coal, completely it will not be possible to automate – fuel needs to be thrown up in boiler fire chamber manually, in process of burn-out. Recently there were solid propellant boilers equipped with automatic fuel supply and using pellets – the granulated waste of the woodworking industry. Such boilers can function in the automatic mode several days. Efficiency of boilers is higher, than normal wood-fired furnaces, and can reach about 75-80%, and the efficiency of gas generators – 87%. In some boilers modern the heat accumulators which are the big tanks filled with liquid are installed. It heats up, accumulating heat which is formed at combustion of solid fuel and then gives it, circulating in heating services, even when the boiler has already stopped working.
Boilers on firm are more often used on large industrial facilities where their operation and service are carried out by experts.
When the boiler uses liquid fuel – diesel, fuel oil or diesel fuel, the heating services functions also, only fuel will be constant and dosed to come to boiler from special capacity. These boilers are distinguished by high efficiency – to 89%, they are economic in service and operation, long time can work in the automatic mode. It is necessary for full operation of such boiler will take care of that there was holding tank of rather large volume providing necessary fuel reserve. Also work of all heating system will depend on conditions of its storage and conformance to requirements of quality in many respects. Boilers, oil-fired, as well as in what firm is used need periodic cleaning and removal of the fuel chambers of combustion products settling on surface. Additional coordination on installation of liquid-fuel boilers will not be required to you, only permission from fire inspection.
The convenient option allowing to pass if necessary from one type of fuel to another are the combined boilers.
The most expensive electric boilers in operation in which water heats up by means of powerful ten, but such heating services are considered as the most eco-friendly. It is possible to automate their work also, but you will need the three-phase power line of 380 V demanding separate coordination with the bodies which are engaged in distribution of electric loads on consumers in your area. It is reasonable to use electric boilers in country houses the big area – 200 and more square meters. It is possible to refer to features of their operation increased requirements to quality of the heat carrier, service water most ruinously influences work of ten. To prevent scaling, it is necessary to add antifreeze or antifreeze to water.
To easy and available ways to make operation of the electric boiler of more economic, installation of the two-tariff counter and use of the heat accumulators allowing to turn on it only at night belongs.
Types of boilers for autonomous heating services
The boilers used in the systems of autonomous heating can be one - and double-circuit. The first will provide the house with heat, and the second both heat, and hot water, but use them in houses which area does not exceed 200 sq.m if the house big, is required to you the powerful single-circuit boiler combined with holding tank for hot water – the boiler. Important question – installation and placement of boiler. It is the best of all to allocate the certain room under the boiler house and to put there floor boiler. When there is no such opportunity, the boiler of wall type which can be hung up in the bathroom or in kitchen will help to save the place. Wall boilers have the smaller power (from 10 to 36 kW) and will not be suitable for heating of big houses.
