Internal or external heater? Choose the right hot tub
Introduction
This blog discusses the choice between an internal or external wood stove for a wood-fired hot tub, an ideal way to relax in the great outdoors. It discusses how wood-fired hot tubs work and why they are so popular. It also compares internal and external wood stoves based on ease of use, maintenance, safety and space efficiency. Read on to find out which wood stove is best suited to a hot tub.
What is a wood fired hot tub?
A wood-fired hot tub is an outdoor bath that is heated by a wood fire. Instead of using electricity or gas, you burn wood in a specially designed stove, which is directly connected to the hot tub. This way of heating gives an authentic and natural spa experience, where you can enjoy warm water in the open air.
The hot tub itself is usually made from sturdy wood such as cedar or spruce, materials that are not only durable but also have natural insulating properties. This helps to keep the water warm for longer. The wood also gives the hot tub a rustic and atmospheric look, which contributes to the overall relaxation experience.
The heating system consists of a metal stove, which can be placed either internally in the tub or externally next to the hot tub. The fire in the stove heats the water, which flows through the hot tub by natural circulation (thermosiphon) or with a small pump. This process makes it possible to bathe outdoors even in colder climates, making it a popular choice for people who want to enjoy the outdoors.
A wood-fired hot tub allows you to relax in an environmentally friendly way, without having to rely on electric heating elements. This offers a unique and energy-efficient way to relax and enjoy your garden or outdoor space.
Advantages of wood-fired hot tubs
A wood-fired hot tub offers many benefits that make it an attractive choice for those looking for relaxation and comfort in their own garden. Here are some of the main benefits you can enjoy:
- Natural heat: The heat of a wood-fired hot tub is deep and natural. The wood fire not only provides a pleasant temperature, but also gives off a soothing scent, which contributes to an authentic spa experience.
- Eco-Friendly: Wood-fired hot tubs use natural fuels and are an eco-friendly option compared to electrically heated tubs. By burning wood, you are using a renewable energy source that is less dependent on fossil fuels.
- Health Benefits: The heat from the hot tub helps relax your muscles, reduces stress, and can even help relieve aching joints. Regular use of a hot tub can contribute to improved circulation and overall well-being .
- Aesthetic Addition: A wood-fired hot tub is a beautiful addition to any garden or outdoor space. The natural wood and traditional design add an element of rustic charm, giving your outdoor space a luxurious and inviting look.
- Social Space: A hot tub is the perfect place to spend time with friends and family. It provides a unique setting for social gatherings, where you can relax together and enjoy each other’s company.
- Independent of electricity: Because a wood-fired hot tub does not use electricity, you can also use it during power outages or in places where there is no electrical connection available. This makes it very suitable for remote locations.
Internal wood stove
An internal wood stove is integrated into the structure of your wood-fired hot tub. This means that the stove is located within the walls of the hot tub and is in direct contact with the water. This arrangement ensures efficient heat transfer to the water, which heats the hot tub quickly.
Benefits of an Internal Wood Burning Stove
One of the biggest advantages of an internal wood stove is its compact design. Because the stove is located inside the hot tub, it does not take up any extra space outside the tub. This makes it an ideal choice for smaller spaces. Furthermore, the direct heat transfer ensures that the water heats up quickly, which is energy efficient.
Disadvantages of an Internal Wood Stove
While an internal heater can be a space-saver, it does have some disadvantages. Because the heater takes up space inside the hot tub, there is less room for users. Maintenance can also be a challenge, as you need to access the heater to add wood and clean out ashes. You also need to be extra careful about safety, as the hot surfaces of the heater can pose a risk within the confined space of the tub.
External wood stove
An external wood stove is separate from your wood-fired hot tub and is connected to pipes that transport heated water to the tub. This design allows the stove to be placed outside the immediate vicinity of the hot tub, which frees up space inside the tub itself.
Benefits of an External Wood Burning Stove
The biggest advantage of an external wood stove is that it does not take up any space in the hot tub, which means there is more room for users to relax. This type of stove is also often easier to maintain, as you can easily reach the stove without having to be in the tub. Another advantage is that the heating capacity is often higher, which means that the water can be heated quickly and efficiently, even in larger hot tubs.
Disadvantages of an External Wood Stove
In addition to the advantages, there are also disadvantages to an external wood stove. For example, installing an external wood stove requires more space around the hot tub, which can be a challenge in some gardens or outdoor areas. The initial installation can also be more complicated, as the stove needs to be connected to the hot tub via pipes. Aesthetically, some people find an external stove less attractive because it stands as a separate element next to the hot tub.
What is the right choice for me?
When choosing between an internal or external wood stove for your wood-fired hot tub, there are several scenarios to consider that can influence your decision. Here are some considerations that can help you determine which type is best for your situation:
Available space
Do you have limited space in your garden or on your patio? Then an internal wood stove may be a better choice because it does not require any extra space outside the hot tub. External wood stoves require more space because they are placed next to the hot tub.
Size of the hot tub
For larger hot tubs, an external wood stove may be more efficient. These often provide a higher heating capacity, which is ideal for larger volumes of water. For smaller hot tubs, an internal stove may be sufficient.
Frequency of use
Do you use the hot tub regularly with multiple people? An external wood stove can be more advantageous because it is generally easier to maintain and heats up faster. This is especially useful if the hot tub is used frequently.
Aesthetic preferences
Do you prefer a sleeker look without visible elements on the outside of the hot tub? Then an internal heater might be more attractive. This type is almost invisible and retains the classic look of the hot tub.
Safety and accessibility
For families with small children or pets, an external wood stove can be safer because it is out of reach of children's hands or pets. The internal stove, which is inside the hot tub, can become hot and therefore pose a risk.
Budget
Your budget can also play a role in the choice. In general, an internal wood stove can be slightly cheaper to purchase than an external stove, depending on the model and size of the hot tub.
Conclusion
In this blog we have described the different aspects of hot tubs with an external and internal wood stove. Making the right choice of wood stove is an important decision that should be well-tailored to your specific needs and circumstances. Both options offer unique advantages and it is essential to weigh them against each other.
With an internal wood stove you benefit from a compact design that does not take up any extra space and ensures rapid heating of the water. However, the space in the hot tub itself is somewhat limited and it requires careful maintenance.
An external wood stove, on the other hand, offers more space within the hot tub itself and is often easier to maintain. This type of stove is ideal for regular use and larger groups, although it does require more space around the hot tub and the initial installation can be more complex.
Ultimately, your choice will depend on factors such as available space, size of hot tub, frequency of use, aesthetic preferences, safety considerations, and your budget. We hope this blog has helped you get a better idea of what each option has to offer, so you can make an informed choice that fits your needs and lifestyle perfectly.
