Autonomous heating for a cottage is fundamentally different from centralized heating systems.
Autonomous heating schemes at home
Autonomous heating of a country house is a complete closed system, which includes:
- Heat generating unit;
- Coolant delivery circuits;
- Heat dissipating modules;
- In some cases, water filters;
- Expansion tanks;
- Relays and microcircuits that control the operation of nodes.
Fuel consumption for autonomous gas heating of a private house depends on the characteristics of the system: the efficiency of the heat generating unit, the design of heat exchangers, and the type of fuel. Parameters such as:
- Insulation of walls, roofs and floors;
- Setting the required temperature level in different rooms;
- The presence of ventilation systems that return some of the heat back to the house;
- The location of the windows depending on the cardinal points and the wind rose.
We can talk about the effective operation of the autonomous heating system of a country house if the temperature in the premises is comfortable for residents. You need to calculate heat losses for each specific cottage. This takes into account the type of pipes used for the heating main, the features of the boiler and exhaust ventilation, as well as the weather conditions and the way of life of the owners of the house.
Conditional autonomous heating of the cottage
An autonomous home heating system, powered by gas or electricity, is considered by experts to be conditionally autonomous. Heating is carried out with the help of boilers that heat the heat carrier - water. The most modern boilers are equipped with automatic control systems and their efficiency is higher than 65 percent, for condensing boilers up to 98 percent.
Such an autonomous heating system for a cottage does not require the construction of a separate room, a warehouse for storing fuel. It can be combined with heat guns, solar and photovoltaic batteries.
Disadvantages of autonomous heating systems
Cons of autonomous gas heating of a private house:
- The temperature in the house depends on the consistency of fuel supply and its quality. If there is insufficient pressure in the system or the gas is of poor quality, the efficiency of the equipment will decrease. Dangerous for boilers and voltage drops in the network. Stopping devices in severe frosts can lead to ruptures of heating mains and radiators;
- It is very expensive to connect an autonomous home heating system to the gas system (including all the necessary documents), and the fuel itself becomes more expensive. Therefore, for the full payback of the equipment, at least 7 years are required.
