All fireplaces have constant, effective, heat-retaining ability as a standard feature
Uunisepät fireplaces effectively retain heat. Hot combustion gases are circulated in inner channels of the fireplace, so that the heat is effectively stored in the frame material of the fireplace, which is “Energy Stone.” Energy Stone is a material combination which resulted from sustained product development. Its composition is excellently suited for fireplaces. This is why Uunisepät offers a 10-year guarantee on it

Double circulation makes the retention of heat more effective.
Double circulation, a system to add effectiveness to the fireplace, enables a greater amount of heat energy from the wood. Since there is then no need to burn a lot of wood, heating is more economical and emissions are also less. In double circulation, combustion gases are led a second time to the outermost duct after the down flow to maximize the retention of the heat energy. From this duct, they are led to the chimney. A summer damper always comes with the double circulation feature.

The summer damper turns a heat-retaining fireplace into a regular fireplace.
Storing heat in the fireplace is not always necessary. The fireplace can be used normally as a heat-retaining fireplace or as a regular fireplace, depending on whether the summer damper is open or closed. It also makes lighting the fire easy, because the draft is more effective when the damper is open while the fire is being lit.

Quick heating with the heat cassette
The heat cassette circulates cold indoor air, heating it inside the fireplace, and then releases it back into the room, heating it. You can order a heat cassette as an additional feature for any Uunisepät fireplace.

Electric resistors
With electric resistors, you can, for example, maintain a steady temperature in a holiday cottage. The heat energy is stored in the fireplace at night using cheaper night-time electricity. In the daytime, when electricity is more expensive, a soft warmth emanates in the room. The installation of electric resistors does not change the other features of the fireplace, so it still heats normally.
