Suburban housing construction is at the peak of popularity, and the reasons for this phenomenon lie not only in the opportunity to live in the lap of nature. Of great importance is the opportunity to enjoy not only clean air, but also comfort. Autonomous communications, including combined heating boilers, are able to provide the family with everything they need: heat, hot water and other benefits of civilization.
Types of Combo Boilers
Modern combined boilers can run on several types of fuel. Among the most common variations are the following types of equipment:
- solid fuels and natural gas;
- natural gas and diesel fuel;
- solid fuel and electricity;
- solid and diesel fuel, natural gas.
Such a variety of options allows you to choose a combined boiler in full compliance with the requirements of the property owner.
All types of combined boilers can be divided into wall and floor, single-circuit and double-circuit. For a small house, a wall-mounted boiler will be optimal, but such models work mainly on natural gas and fuel. If combined heating boilers use firewood as one of the types of fuel, then they will most likely have impressive dimensions. After all, it is necessary to lay a sufficient amount of firewood, and this requires bulky cameras. As a result, solid fuel combi boilers are represented by floor models.
Today, electricity has received the maximum distribution, to any country house summed distribution network. This makes a single-circuit or double-circuit boiler of this type the best equipment for a country house. But, on the one hand, heating with electricity is expensive, they prefer to use it only as a backup energy source. On the other hand, wires in the winter at any time can break under the weight of sleet or wind power. For this reason, the combined boiler "firewood-electricity" has become popular with owners of suburban real estate. In the event of a break in the electricity supply network, it is enough to throw in firewood and the house will be warm and cozy.
The best choice for property owners in the new cottage settlements is a solid fuel-gas boiler. Where they promise to bring the main natural gas in the near future, coal and other solid fuels can be used to heat up to the implementation of this project. It can be firewood, peat, pellets - small granules of pressed sawdust.
Depending on financial possibilities, you can choose one-furnace or two-furnace combined gas-firewood boiler. Models with one firebox have more compact dimensions, but transfer from one type of fuel to another will take time. Two-furnace boilers have a gas burner installed in the lower furnace. During the work on blue fuel all design gets warm that significantly increases efficiency.
The disadvantage of such models is the ingress of ash into the lower chamber. There are two fireboxes when cleaning the boiler, but this is typical for low-cost models. The top boilers are equipped with a special pallet installed under the upper heating chamber, in which solid fuel is burned. They protect the lower firebox from ash.
The widespread availability of diesel fuel has become an excellent reason to supplement the gas boiler with another burner. As a result, the opportunity to work on one of two popular energy sources. Such cast iron boilers are characterized by high efficiency, and single-point models attract an affordable price. When changing energy, it is enough to change the burners, which are in many ways similar to each other and therefore the fuel is changed quickly.
Such mixed boilers have a disadvantage; it lies in the high costs of arranging the system for storing diesel fuel and its supply to the boiler room. It is necessary to purchase a container, complete it with breathing valves and other specialized equipment. Delivery of diesel fuel also differs significant costs.
Manufacturers of heating equipment have developed a combined solid fuel boiler that can run on diesel fuel, natural gas and electricity. Such versatility is relevant for holiday homes, resorts, motels, other suburban commercial real estate. Such a combined boiler works on pellets, coal, wood and other types of fuel. A wide range of energy options allows you to constantly use two or three types of fuel, without fear that the object will be left without heat. In the extreme case, the backup option will be the transfer of equipment to electricity.
Available energy sources are the main criterion for the selection of combining boilers. The most popular models are fuel equipment, necessarily running on coal or wood. The popularity of pellet boilers is growing, this environmentally friendly fuel is becoming more affordable. They show good efficiency, which is not lower than that of a wood boiler.
In addition to the choice of fuel, which will operate heating equipment, it is necessary when choosing a boiler to pay attention to important technical characteristics. The main parameter of this technique is power.
Regardless of whether you choose a gas-to-electricity combined boiler or other model, performance should be sufficient to heat your home. With standard ceilings and an area of heated space of 300 square meters, the power of the combined boiler must be at least 30 kW.
