The Sawo Tower Wall heater is a great choice for any small or mid sized sauna room. The TH4 Wall is only 475 mm wide and 250 mm deep, so very compact, but there are power versions up to 9 kW, for installation into a sauna up to 14 m³ in volume. This heater model is very popular, and really suitable to a wide range of sauna designs. No compromise from how great the sauna heater looks or how ample heat and steam it generates.
Stone space with the spacer 120 kg, without 90 kg.
In choosing your heater, check the available electrical connection you have, then choose the sauna heater power according to your room size. We recommend choosing the more powerful sauna heater if you are pondering between two power versions.
If your sauna has windows or glass surfaces, or other non-insulated surface like stoneslab or tile wall, calculate that each square meter of such will add one extra cubic meter to your sauna volume, when choosing the heater.
Tower heaters have a removable center metal box (called spacer) that allows you to choose the characteristic of your heater: keep it in and heating-up is faster, remove it to fill the heater with stones and enjoy the full endless steam from the larger stone quantity.
