How many times would you like to heat your fireplace per day? The chart below shows a comparison between a traditional fireplace and a Tulikivi soapstone masonry heater. The pleasant radiant heat of a Tulikivi heat-retaining masonry heater lasts a whole day.
A soapstone stove with a smaller mass retains less heat and cools more quickly than a large one. A larger masonry heater stores more energy, which is released slowly into the room, keeping it warm for a long time. However, a Tulikivi soapstone heater always soundly beats a wood stove, for example, which only gives off heat for a relatively short period.
In the first example, a small Tulikivi fireplace achieves its peak instantaneous heat release (3 kW) approx. 2 hours after heating is started. This fireplace continues to release 50% of its heat output 8 hours after heating is started and 25% of its heat output 14 hours after heating is started.
In the second example, a large Tulikivi fireplace reaches its peak instantaneous heat release (3.6 kW) approx. 6 hours after heating is started. It then releases 50% of its instantaneous heat output 18 hours after heating is started and 25% of its instantaneous heat output 31 hours after heating is started.
