Boiler Boilers - Good Tips When Choosing Fireplace Boiler


The wood pan is a classic in the Swedish households. Since ancient times, we have warmed up our homes, and have been able to warm up our homes. Today, the wood pan is the most common heating method for houses in the country. So, it will be in the future as well. Modern wood burning boilers are considered to be environmentally sound and effective. It is also, for those with access to wood, a cheap way to keep the heat in the house. The big drawback is, however, that the woodburning stove requires its maintenance.

What is required

To install a wood burning boiler requires a space for the boiler. It's quite big. Until there is room for the wood itself and thereafter accumulator tanks. Then a chimney to which the boiler can be connected and a waterborne system in the house are also needed. Even electricity needs to be connected. The water in the waterborne system is transported by a small pump which is powered by electricity.

Fireplace or combination boiler?

A boiler can come as an individual unit and, in principle, it is always always fitted with an electric cartridge. The electric cartridge may be allowed to enter when the firewood does not provide sufficient power over a predetermined temperature, or function entirely on its own. There are also wood-type wood-burning boilers to choose from. They allow several kinds of heat sources. A common example is combinations of wood / pellets. Another variant, albeit more modern, is a combi boiler where both oil and wood can be used. A wood burning system can also be connected to other heat sources, as the boiler is connected to a waterborne heating system and has accumulator tanks.

Power

The boiler has an efficiency of up to 85%. This applies to modern wood burning boilers. The better the combustion effect that the boiler has, the less environmental impact it has. There are even boilers that are Nordic Ecolabelled. They are both energy efficient and efficient.

Modern combustion technology is a lot more environmentally friendly than previous versions. Nowadays the boilers come up to temperatures of 850 degrees, which guarantees full combustion. It provides the least possible smoke. The high temperature is available in the gas combustion chamber. Boilers lacking such one, but instead water-drained, can not be as effective. They are also less environmentally friendly.

Structure

In a modern wood burning boiler there are three zones: the fireplace itself, the gas combustion space and the space for convection - the transfer of heat from flue gases to the water system. The gas combustion space is the one that gets warmest. The walls are therefore protected by ceramic tiles or the like that can withstand up to a thousand degrees of heat. The boilers sold to private individuals are almost always handmade. By inserting a few times a day.

Burning Principles

The type of combustion that the boiler offers affects the effect. The classic is over combustion. The air supply is then carried out from below on the top of the forehead, such as a chimney. Sub-combustion is a developed variant of combustion. The difference is that the output of the flue gases that are formed is also taken out in the bottom of the forehead. It makes a decisive difference for burning the wood. In case of overburning, the entire wood volume is burned at once. In case of incineration, it burns the lower part of the wood pulp. The rest of the heels then drops slowly downwards to become burned when it is reached low enough. This gives a good, much more efficient combustion. However, a difficulty with such boilers is that the rows of wood must be soaked that the feed downwards does not hang.

Several modern wood burning boilers are based on reverse combustion. Here the air is taken from above and the airflow goes down in the forehead. Even here it is the part of the annexe that burns first. For this boiler to work as it is supposed to be, it is equipped with a fan that controls the air's movements.

Storage tank

In order for a boiler to be really efficient, it needs to be installed together with one or more accumulator tanks. The tanks consist of water that is heated by the firewood. This water then spreads through the waterborne system to radiators or underfloor heating. It is also possible to collect hot water through the water system. If no accumulator tanks are connected, constant fire is required to heat the heat to the radiators in the housing. It also applies that the storage tanks are large enough for the heat to be as evenly distributed as possible over time. It is not entirely unusual with two 500 to 750 liters.

Hot water

In addition to heating, a boiler can supply hot water to the household. It's a cheap and convenient way to heat the water, but can cause problems during the summer. Then there are few who either want or can not keep the wood pan running, for the sake of hot water only. In the winter during very cold days, it can sometimes be difficult to keep warm in the house, while the whole family may think that a wonderful bath is recommended. It can make the heat generated by wood burning not enough for both heating and hot water. One solution to the problem is to serialize a regular water heater. It is heated as soon as the power is allowed by the boiler, but the heat is also guaranteed by the electricity that turns on when needed.

Advantages

Firewood is a very attractive choice for the household that is in the country and has access to cheap by. It can be about taking care of the ground around, or having a good supplier. In order for a modern boiler to provide enough heat, one or two charges must be sufficient. Then all the water in the storage tanks must be heated. When the wood is well-stocked, it means a bit of cuddle, but also a very economical form of heat.

Disadvantages

It takes a lot of work and space with wood burning boilers. No matter how effective it is, it must be available continuously. This means work several times a day. In addition, soaking and other maintenance, which is required for the boiler to not be dangerous to use, as well as the fact that the wood must be processed before it can be used. Firewood is not always as cheap as it seems. For those who can not or can not handle the work to take care of, the cost is sometimes great for buying it. Till that comes the smoke that is delivered when the boiler is used. In some residential areas, this is not seen with gaze.

Buying

Before a wood paneling, it takes into account a variety of factors. There are a variety of boilers with different efficiency and effect to choose from. Which boiler fits best in the individual case depends on the available space, the size of the house and, of course, the bid that is available. The rotary deduction can be used for installation of the wood pan. In some cases, there may also be support for replacing the old wood pan with a new, more energy efficient. Consult your municipality as to what is applicable. It's wise to do, even because a building permit may also have to have a wood pan as a heating system before the house. In addition, the municipality has energy advisors who can advise on the choice of the right firewood for your house.
