Moduls & Blocks

Accumulation is an ancient and well-known way to keep warm in stone for a long time, enjoying a gentle uniform heat for a long time. Now the stove accumulation is going through its second birth. Deaf inconvenient doors are a thing of the past, as is the technology of their masonry. The modern continuation of the kiln tradition is the stoves and fireplaces, which combine the aesthetics of the fireplace and the stove accumulation tradition.

What is accumulation for?

The tradition of soft heat

With the rising cost of energy, the demands for wood heating dictate high efficiency and comfort. The fire in the fireplace does not burn evenly: at first a small amount of heat is released, then it rapidly increases and the heat becomes excess, and after active combustion the furnace and fireplace are rapidly cooled and the heat does not run out again. Sometimes there is no need for heat from active combustion, but the slow burning mode does not give the desired effect. An accumulation system capable of providing heat over a long period comes to the help.

 

 

 

 

Planning

Calculation of the power of the furnace

The capacity of the firebox shall be calculated in accordance with the installed system (with or without heat channels) and the heat losses of the premises planned to be heated by the fireplace. So, the room with the fireplace will emit the most heat from the fireplace lining and glass.

The power fraction of the furnace emitted through the glass is about 30%.

That is, the heat loss of the room where the fireplace is located should be such that heating the fireplace does not create discomfort.For example, if the area of ​​a room is about 35-40 square meters, you can count on a heat loss of about 3kW (this value is statistical and requires a separate study for installing). From the fraction of power of the furnace it follows: 3kW / 30% = 10kW of rated power. The power of the furnace should not be chosen so that its nominal power exceeds that value substantially; at the same time, too little power will not provide enough heat.

The nature of the burning of firewood provides nonlinearity of heat output, therefore characterizing its power introduce a range of working capacities. It is possible to calculate the amount of heat released during combustion from the amount of firewood laid: 1kg of firewood leaves 3.5kW * hour of heat. Burning 4kg in 2 hours can be obtained:4kg * 3.5kW * hour = 14kW * hour, 14kW * hour / 2h = 7kW.

Quality and guarantee

Quality
Buying a Gavryliv & Sons firebox gives you a product that is made by skilled workers and goes through several stages of quality testing. All firebox models are tested on the stand, including stress tests to ensure a high level of safety and many years of trouble-free, happy use.
Guarantee
By accepting quality as a rule, Gavryliv & Sons accepts product liability, so a five-year warranty applies to all the company’s products.

How does it work?

The picture shows a cross-section of a firebox. Arrows indicate the location of air flows. The cross section of the air supply duct provides the optimum distribution for primary firing and the clear glass system. For the self-cleaning glass, air is washing it from the upper channel, and forming a protective screen, resulting in it self-cleaning (soot and dust, which settle on the glass, are burned with increasing temperature).  The profile of which the door is made is continuous-bent and has a special groove for the sealing cord, this design prevents air from penetrating through the cracks and ensures that the furnace is sealed. The clear glass system does not break the tightness of the furnace. These technological solutions help the firebox to work effectively.
