An outside stove is very convenient in operation and maintenance As the heater is mounted separately, it allows to save a lot of space inside the hot tub. In case you need high-quality stove, pay attention to outside aluminum stoves, which heat water quickly with minimum firewood waste. Baltresto offers two aluminium models – 27 kW and 35 kW. The first model is smaller in size and a bit less powerful, which makes it suitable for smaller hot tubs. Choosing a hot tub of smaller diameter with the outside aluminium 27kW stove, you will get perfect bathing experience at a reasonable price! For bigger hot tubs Baltresto has developed an advanced aluminium 35kW stove. Significant advantage of this model is ability to regulate air supply, which also means the opportunity to control stove capacity. In addition, there is a new kind of a door handle, which makes opening even more safe and comfortable. One more positive change is bigger firebox, which accommodates more wood. As a result, you do not have to add firewood many times. Please make sure, there is no water left, when the stove is not used during the winter time. In case this rule is not observed, water may freeze and damage the stove.
