We love using IKI heaters in our builds.
Every one is still made by hand in Finland, in the same workshop, by people who have spent decades making some of the best sauna heaters around. The name means forever, and that is more or less the promise. These outlast the sauna around them.
IKI is also the heater that changed the category. They were the first to wrap the heat source in an open mesh frame packed with stones, instead of hiding a few rocks behind sheet metal. Almost every good heater since has copied the idea. The reason is löyly. All that exposed stone holds a deep reserve of heat, so the steam comes soft and full instead of sharp and thin.
It’s a heater we always enjoy building around.
