Efficient solid fuel boilers

Heating systems using solid fuel boilers.

Many people now ask themselves: - Is it possible to build a heating system on a solid fuel boiler, while achieving comfort in maintenance and at the same time substantial fuel savings?

Yes it is possible! But with certain conditions. Unfortunately, there is no one-size-fits-all solution for everyone. From our own experience, we can say that only an individual approach to each customer can ensure the golden rule of price / quality.

Let's try to make out the basic nuances that we pay attention to during the initial diagnosis of the building. First of all, you need to decide on the source of energy. Since we are talking about solid fuel boilers, it is worth noting that there are several types:

- solid fuel boilers traditional, natural combustion (characterized by the usual (natural) combustion process, simple equipment, not expensive, not demanding for the quality of fuel, easy to maintain)

- Pyrolysis gas-fired solid fuel boilers for long burning on wood (working on the principle of gasification of fuel, there is a feature in the construct (the boiler is divided into a compartment), increased efficiency compared to natural combustion boilers 85-90%, the duration of combustion is up to 12 hours per one

- solid fuel boilers with secondary air supply (additional air supply to the top of the furnace, thus increasing the efficiency compared to conventional boilers, but the parameters of loading and combustion as well)

- heating solid fuel boilers for long-burning firewood in the upper layer (at one load, the burning time reaches 32 hours, high efficiency up to 92%, the possibility of smooth regulation from 10 to 100%, but there are requirements for the humidity of the firewood at loading: no more than 20-30 %)

- automatic solid fuel boilers (coal pellets are used as fuel (a certain fraction depending on the model of the boiler) or wood pellets / pellets, peat and so on, the possibility of changing the hearth to use other fuel (gas, liquid fuel), the possibility of installing grate, almost automatic boiler operation)

Once we have determined the type of boiler, you can search for the appropriate make and model. The next point will be determining the capacity of the solid fuel boiler.

The ideal option is to select the boiler power according to the heat losses of the heating object. From this you should first calculate the heat loss of your home. Improperly selected boiler output will either cause the house to overheat (pay for large fuel bills) or cause a low internal temperature in January frosts.

It should be noted that for a home built using modern energy-efficient practices in technologies and designs, the boiler capacity can be reduced by up to 50%.

Also in our practice, we recommend using buffer tanks. The advantages of this solution include:

- temperature drops are less noticeable when using a solid fuel boiler;

- process automation;

- possibility of surface temperature control;

- possibility of connection of an additional source of energy (for example a gas boiler);

- possibility of connection of solar collectors later;

The next steps are to select heating radiators, circulation pumps and all accessories.
