What Are the Cons of a Wood-Fired Hot Tub?

The wood-fired tub is a great way to heat a hot tub, but it does come with some drawbacks. The first issue is the cost. Wood-fired systems can be much more expensive than electric or gas fired alternatives.

Additionally, wood fire tubs require substantial upkeep and maintenance to ensure that they are burning safely and efficiently, which can add up over time. There are some serious cons to wood-fired tubs:

1. Environmental Impact:

Burning wood releases carbon dioxide and other greenhouse gases into the atmosphere, which can contribute to global warming if done on a large scale. Even if a wood-fired hot tub is used sparingly, it still has an environmental impact due to its dependence on a finite resource.

2. Maintenance Requirements:

Wood-fired hot tubs require more maintenance than other types of hot tubs since the fire needs to be tended to regularly, and a supply of wood must be available for fuel.

3. Cost:

Wood-fired hot tubs can be expensive due to the cost of the materials needed and the installation process. The purchase price may not include the cost of delivery, setup, and safety equipment which can add up quickly. Additionally, you’ll need to factor in ongoing costs such as wood, propane, or heating oil for your heater, if applicable.

4. Health Concerns:

Carbon monoxide is a byproduct of burning wood in a wood-fired hot tub, and it can pose a health risk if inhaled at high concentrations. It’s important to make sure the hot tub is well-ventilated and that you have a carbon monoxide detector installed. You should also avoid overexposure to heat and steam, as this can cause dehydration or overheat.

5. Structural Integrity:

Wood-fired hot tubs have an increased risk of structural damage due to their proximity to the fire source. It’s important to make sure that the hot tub is constructed properly and regularly inspected to ensure that it is safe and secure.

9 Methods How to Cool down a Wood Fired Hot Tub

1. Add Some Cold Water

Use a Garden Hose

One way to cool down a wood-fired hot tub is to add some cold water to it. This will help to lower the overall temperature of the water. You can either use a garden hose or a bucket to add cold water.

Be sure to add a small amount at first, as adding too much cold water can shock the system and make it difficult for the tub to maintain an even temperature.

Although it may take some time for the cold water to lower the temperature, it is an effective way to cool down a hot tub without using electricity.

2. Shade the Hot Tub

Another way to cool down a wood-fired hot tub is to shade it from the sun. If the hot tub is in direct sunlight, the water will heat up quickly. You can either put a tarp over the hot tub or move it to a shaded area. You can also use a canopy over the hot tub to provide shade. If you don’t have access to any of these, try using a large beach umbrella to provide shade.

This will help keep the water cool and prevent it from heating up too quickly. However, be sure to take the umbrella down when you’re not using it, so it doesn’t blow away. Additionally, if you live in a sunny area, you may want to consider investing in some solar panels to help keep the hot tub cooler. This will reduce your energy consumption and help the environment.

3. Use a Fan

Help to Circulate the Air

Using a fan is another effective way to cool down a wood-fired hot tub. The fan will help to circulate the air around the hot tub and will also evaporate some of the water, which will help to lower the temperature.

Place the fan at one end of the hot tub and point it towards the opposite end, or use multiple fans placed around the entire circumference of the hot tub.

This will help to cool it down evenly and quickly. Make sure the fan is not too close to the hot tub, as this could cause water splashing and can be dangerous for anyone in or around the hot tub. Additionally, check that the fan is safe to use with water, ensuring it has all the necessary safety features in place.

4. Freeze Some Water Bottles

You can also freeze some water bottles and then place them in the hot tub. This will help to lower the temperature of the water and will also provide you with some ice-cold water to drink. Make sure to wrap the bottles in a cloth or towel so that they don’t touch the sides of the tub.

Additionally, it’s important to use water bottles with screw-on tops rather than bottles with open tops since these can leak when thawing. You can also reuse them by refreezing them and using them again. This is a great way to stay cool in a wood-fired hot tub.

5. Turn off the Wood Fire

If you have a wood fire going in your hot tub, then you should turn it off. The fire will obviously make the water hotter, so you want to avoid having it on if you’re trying to cool down the tub. At the same time, you should also make sure to open any vents that may be near the fire so that as much of the heat can escape as possible.

You may even want to consider using a fan or two to help circulate the air and get rid of any heat that is still lingering around the area.

6. Leave the Cover off

Leaving the Cover Off

Leaving the cover off of the hot tub will also help to cool it down. The cover will trap heat in, so by leaving it off; you’ll allow some of that heat to escape. This can also help to decrease the amount of time it takes for your tub to get back up to a safe temperature.

Additionally, you should avoid using an insulated cover or a floating foam blanket, as this will hinder the cooling process. If you’re concerned about debris or insects getting in your hot tub, you can purchase a mesh cover that will still allow air to circulate while keeping out unwanted pollutants.

7. Place Ice Cubes in the Tub

Another way to lower the temperature of the water is to place ice cubes in it. This is especially effective if you have a large number of ice cubes. You can either use regular ice cubes or dry ice cubes. To make dry ice cubes, use a food processor to chop up some dry ice into smaller pieces and then place them in the hot tub.

Make sure you don’t put too many pieces in at once, as they will cool down the water very quickly.

8. Use Evaporative Cooling Pads

Evaporative Cooling Pads

Evaporative cooling pads are specifically designed to lower the temperature of hot tubs and pools. They work by evaporating water, which helps to cool down the surrounding air temperature. You can install them directly in front of the hot tub to provide maximum cooling power.

9. Use a Pool Cover Pump

A pool cover pump can also be used to cool down a wood-fired hot tub. The pump works by circulating the water and evaporating it, which helps to lower the overall temperature of the tub. The pump should be placed in the center of the tub and the hose should be extended down to the bottom.

This type of pump works best when used with a timer so that it can run for several hours each day during peak heating times. Make sure to check that the water level does not drop too low, as this may cause problems with the pump.


Overall, it is best to avoid adding water when the wood-fired hot tub is already in use. If you must add water, do so gradually and wait for the temperature to equalize before using the tub again. These tips should help keep your wood-fired hot tub running smoothly all season long.
