In modern buildings, especially those well insulated, forced heat distribution is not the optimal solution. The primary medium responsible for temperature balance in the room is air. If in your home thermal bridges and leaks doesn’t occur, the room should heat up evenly. In such conditions, the best heating solution for home is so called warm surface.

Fireplace warm surface doesn’t require to build an isolation system what also would be connected with the troublesome and expensive installation of hot air distribution system. Of course, the approach to the topic should always be individual. We have to consider the advantages and disadvantages of various heating solutions and implement those which will be the best in our case.

First of all, traditional fireplace warm surface gives the possibility of economical energy use, released during combustion of either wood or other fuels. Heat distribution base on temperature differences. Regardless of the mechanism we use, the result is always determined by temperature of the source and the receiver. The heated fireplace body, allows you to maintain a pleasant temperature in the room. The effectiveness of such solution is much better than in conventional heating systems supplied by convective fireplaces – heating the room only through the glass. Fireplace insert body built of heavy plates gives off its heat by radiation, as well as a tiled stove. Along with a well-matched heat exchanger, the fireplace body gives us full use of its potential and economical home heating.

Each object needs time to warm up. Each, however, has its limits. The consequence of this may be overheating of the rooms where the fireplace is placed and energy losses (through ventilation and walls). Loss of heat refers to the same laws as its distribution – the temperature difference. Accumulative warm surface changes the nature of the heating in time. In addition to increasing the fireplace efficiency, the heat is being supplied smoothly and last longer, what makes that more of heat stays in the house.

To make the topic of fireplace warm surfaces complete, we should definitely mention the various types of accumulative heat exchangers. They increase the efficiency of the entire system in the process of heat recovery from the flue gases. The heat produced by exhaust gases is being absorbed and used to maximally increase the heat given away to the room and prevent the passing up of the whole warmth through the chimney.

In the case of energy-efficient houses we should consider a more complex exchangers and heat absorbing mass. The solutions and materials preferred by Unico provides both safety and comfort when using the fireplace. All inserts produced in our company are suitable for the warm surfaces. We provide service to the customers and partners. We offer help and information in choosing, shipping and calculation.

Definitions of terms used in the text:


The heat – energy form which quantity in nature is constant. Our stoves and fireplaces only change its form. It changes the chemical energy contained in the fuel into thermal energy.
Power – the amount of energy, also the heat, in time. The same amount of energy can be delivered faster, what means more power.
Temperature – is not an energy so it isn’t also a heat. It only specifies the amount of energy contained in the particular object. Two different materials in the same quantities and at the same temperature usually don’t have the same energy – they need different amounts of it to warm up.
