Why buy a wood fired hot tub instead of an electric one?

There are a few reasons. One of them is that a wood burning hot tub is far easier to maintain and has pretty low running costs. It takes approximately 2 hours on average to heat up a wood burning hot tub, while it takes 12-24 hours to heat the same amount of water with an electric heater.

What installation work is required for my wood burning hot tub?

There is not much installation work needed. All you need to do is unpack the wood fired hot tub and place it on a stable, levelled and even base that can bear the weight of the tub (a hot tub filled with water can weigh approx. 2,000kg).

You will need a qualified electrician to connect the hot tub to an external socket. Please ensure this work is carried out by a WA registered electrician.

How long will it take to heat up the water in my wooden hot tub?

In summer, it will only take around 1 hour to heat the water to the desired +39℃. In winter, you’ll need 2-3 hours to do the job.

Heating efficiency will depend on the weather, the initial temperature of the water inside, as well as your firewood choice.

How many people can fit in a Gardenvity hot tub?

It will always depend on your personal preferences when it comes to how much space you want to have around you when bathing.

There are two sizes available when ordering a Gardenvity wooden hot tub – 180 cm and 200 cm, which will seat 6-8 people (6 adults+ 2 children) and 8-10 people (8 adults + 2 children), respectively.

How does a wooden hot tub work?
It’s quite simple. Burning firewood in the heater warms the water, which then flows upwards pushing the cold water down and thus circulates continuously.
Do wood fired hot tubs need chemicals?

Our hot tubs contain an internal water filter, however, we recommend to use the same type of products you would use for a traditional spa or swimming pool.

Do wood burning hot tubs bubble?

A wood burning hot tub with an installed whirlpool spa is run with electricity and the water does bubble. The air jets circulate the water, making the air bubbles rise from the bottom up.

Do I have to clean out my wooden hot tub’s heater frequently?
You don’t have to empty the wood fired hot tub’s heater out completely every time after use. It should work fine as long as there is enough room for the air to circulate and keep the fire going. Before cleaning out the ash, make sure the embers have cooled down and use a long-handled shovel to handle them.
Will there be a lot of smoke?
Once you light the firewood, some smoke will come out until the fire reaches the optimum burning temperature. As long as you’re using dry wood, not much smoke is produced, only enough to create a soothing atmosphere.
What is the ideal water temperature?

No matter what time of the year it is, we advise keeping the water in the wood burning hot tub at +39 °C as heating the water any higher can cause you to overheat, dehydrate and experience headaches. For those who have heart issues, you should avoid bathing in high temperatures.

How do I control the temperature of the water?
Every Gardenvity wooden hot tub comes with a floating thermometer. Use it to monitor the temperature when the water is heating. Once you reach +39 °C, simply stop adding wood to the burner. If the water is too hot, then add cold water with a garden hose or open the cover – with time, some of the heat will escape.
Is it easy to drain the water out?
Yes. Every wood fired hot tub has a standard, external water drain valve at the bottom of the hot tub next to the heater.
Do I need to treat the outside of my wood fired hot tub?

No, the exterior of your wood burning hot tub doesn’t need any extra maintenance as it is made from Thermowood, which is already treated thermally. Over time, the surface of the wood will become greyish as all-natural wood does. If you wish to maintain the original Thermowood appearance, treat it with transparent paint containing some brown pigment.

What is Thermowood?

It is high-quality, heat-treated timber. The moisture and resin in the wood are completely dried out during the treatment, making it highly resistant to all kinds of weather and temperatures. Our wood fired hot tubs are made with a Scandinavian Thermowood finish, so they are suitable for outdoor use all year round.

Does the wooden hot tub fade over time?

Yes, as all natural wood does, the surface will gradually fade to a greyish colour, which looks pretty charming. If you want to maintain the original colour, you can paint your wood fired hot tub’s exterior with transparent paint that has brown pigment in it.

What is the best type of firewood to use?

To efficiently heat the water in your hot tub, we recommend using dry firewood, such as jarrah.

Can other solid fuels or types of wood be used?

No, it is strongly advised to not use any other type of fuel or wood that is not firewood for your wooden hot tub. Dry firewood is generally better for the environment and gives the best results. Using any other kind of fuel can damage the heater.

What should I do with the ash?

Once they are cold, the ashes can be safely disposed of in a bin. When mixed with soil, it is also a great compost for your veggie garden.
