„Harvia Hidden Heater“ – an exclusive electric sauna heater, designed for saunas with minimalist and modern design. This model is installed behind benches or special constructions, so the heater remains almost unnoticed and allows creating an extremely clean and elegant sauna interior.
Despite the hidden construction, „Harvia Hidden Heater“ ensures efficient heating and soft, even steam. The large stone capacity allows more heat to be accumulated, so bathing becomes comfortable and pleasant.
The heater is made of high-quality stainless steel, so it is characterized by durability and reliable operation. The model is perfectly suitable for modern home saunas, SPA spaces, and projects where minimalist design and hidden technical solutions are important.
