People usually talk about expensive electric tubs without even considering wood fired hot tub options. While electric spas are more convenient, wood-fired ones are cheaper, and that’s something to have in mind when choosing between these two models.

Having a hot tub in your backyard is a great way to spend some time relaxing, enjoy sunny weather, and even invite a couple of friends for a bath. To know which option to choose, in this article, we will discuss how a wood-fired hot tub works and why you should invest money in this model?

How does it work?

With this type of tub, the warmth is generated by the heater for most of the year. However, the customers can choose between two different heaters, external and integrated. When it comes to heating, gravity plays a significant role since it allows efficient water heating.

The warm water accumulates at the top, while cooler water remains at the bottom. On the other hand, a heater and hot tubes are installed outside the hot tub. One is placed at the top while the other is installed at the bottom.

The tube located at the bottom intakes the cold water and moves it to the heater, to get hot enough and then discharges it back into the hot tub through a top tube. As long as you are heating the water, this cycle will continue. So, basically, this is a primary concept of every wood-fired hot tub.

Can you have a woodfire hot tub with jets?

We should mention all jacuzzi accessorize used nowadays are powered by electricity. But, even if you have a wood fire hot tub, you can still install jets. There are two types of jacuzzi accessorize, which are also known as massage system.

For instance, an average hot tub requires approximately 12 jets placed at the bottom of your spa. In this way, bubbles emerge from the ground, creating a stunning effect.

On the other hand, we have a hydromassage scheme as well. In this case, the jets are fitted inside the walls. These types of jets are stronger and directly impact your body. Since they are water-powered, they must the removed during winter months; otherwise, the water will freeze inside and damage the jets.

When it comes to operating a hot tub, this one requires little more work than an electric spa. However, the basic principle is the same.

Additionally, the heat stratifies, which means hot water lingers at the top while cooler water sticks to the bottom.

To prevent this from occurring, you will have to use a paddler to stir the water while bathing. When you light the fire, make sure to use a clan fire paper, and then switch to a dry light covered. There is a simple rule, the more wood you use, the faster the water will reach the desired temperature, and the more wood you add, the longer you will maintain a steady temperature.

If your water gets hot too quickly, reduce the use of wood, and minimize the airflow. At this point, the water should cool down fast. Also, make sure that the wood heater doesn’t get too hot; otherwise, it will melt. That’s why it’s crucial to monitor your cooling system.

Smoke is a potential issue for many tub owners. However, if you use high heat and low smoke fuel sources, you shouldn’t experience any problems. Keep in mind that your firewood must be dry and not green. Remember to clean the chimney regularly and remove any obstruction, to prevent excessive smoking.
