Advantages and Proper Use of the Wood-Fired or Electric Wooden Hot Tubs

by | Aug 15, 2025 | Wood Hot Tub Category

Bathing in a wooden hot tub is a relaxing way to de-stress, relieve fatigue and post-workout muscle aches, and improve blood circulation. There are two common ways to heat a tub: an electric constant-temperature furnace and a wood burning stove. Wood burning stoves can be built-in or external. Let’s discuss the advantages of each and how to use them correctly.

Advantages of Wooden Hot Tubs with Different Constant Temperature and Heating Systems

Different constant temperature and heating systems have their own advantages. Using an electric stove to maintain constant temperature is more convenient and simple to operate, while a wood-burning stove mainly uses firewood, a renewable resource, for heating. It heats quickly, is sustainable, and provides a good outdoor experience.

Wooden Hot Tub with Electric Stove

Easy to Use: Plug and play for simple operation. No need to light a fire, making it easy to use.
Multiple Nozzles: Featuring a flush nozzle, it can be equipped with a massage system for body therapy.
Constant Temperature: Electric stoves have a thermostat, so they can’t reach high temperatures, making them suitable for those with lower heat tolerance. While they heat up longer, they maintain the temperature for a comfortable soak.
Easy Installation: Flexible installation options are available, including indoor and built-in installations.

FAQS

Question 1:Can I Customize a Hot Tub with Both an Electric Thermostat and a Wood-Burning Stove?

Answer:Of course! Our Alphasauna offer a variety of custom solutions. We can create a dual-system hot tub with both electric thermostat and a built-in or external wood-burning stove, tailored to your needs. You can freely choose the size and features (such as massage jets, LED lights, Bluetooth speakers, etc.) to meet your individual needs.

Question 2:How Long Does It Take to Heat up a Hot Tub with a Built-In Wood-Burning Stove?

Answer:For example, a round hot tub with a diameter of 1500mm*1000mm and a power of 15 kW will heat up faster with a built-in wood-burning stove. Depending on the water volume and ambient temperature, it will take approximately 2-3 hours to heat the water to a comfortable bathing temperature of 38-40°C.

Question 3:How Long Does It Take to Heat up a Hot Tub with an External Wood-Burning Stove?

Answer:Taking a round hot tub with a diameter of 1500mm x 1000mm and a power of 12kW as an example, due to the large water volume and the separation of the heater from the water, the heating time is typically around 3-4 hours. However, it provides stable and continuous heat, making it particularly suitable for large bathtubs used by multiple people.

Question 4:Can an Electric Thermostat Be Used Alone? Does It Consume a Lot of Power?

Answer:An electric thermostat can be used alone and is particularly suitable for daily use. It automatically maintains the set temperature, eliminating the need for frequent heating and saving energy.
