Internal, external, or integrated wood burner

Still not sure which type to go for? We understand, it can be one of the most difficult decisions when choosing your wood fired hot tub. 

Internal wood fired burners, where the burner sits directly in the tub with it's occupants, are typically the most efficient way to heat your hot tub water. As the furnace has maximum contact and surface area with the water, this typically causes the water temperature to increase quickest out of the three major setups. The internal burner is typically separated from the occupants by a wooden fence, although it is still in close proximity and would not be best suited to those who intend to use the tub with children. Another consideration with the internal burner types are that the furnace takes up considerable room in the tub, meaning less room for occupants. These tubs are ideal though as they represent the best value for money for a majority of users.

Next are the external wood burner hot tubs. The heater is separated from the tub via pipes and leaves the fibreglass shell of the tub looking most similar to that of a traditional jacuzzi, as there is no sacrifice of space in the tub for an internal or integrated burner. These external burners can be located away from the tub for safety, or due to lack of space. One consideration with external heaters are that depending on the distance away from the hot tub, the heat loss can be greater than internal or integrated designs, which means more firewood and longer heating times. External circulation pumps can help with this, and external burners are very popular due to their versatility.

Finally, integrated burner designs represent the most popular choice, due to their compromise of internal tub space and minimal footprint in the garden. They are usually considered the most sleek and visually impressive in terms of the design, and offer lower levels of heat loss than external heaters, whilst saving room for extra people in the tub.

FAQs

 

I see you there’s lots of wood options available, which should I select?

We offer 6 different wood types and they all have their own advantages and disadvantages:

  • Fir is our cheapest option. Visibly it has a light shade and may have some knots which are visible, however it is a pretty robust material and should last for several years if you look after it with the right care and attention.
  • Pine is one of our more popular options. It should be noted that pine gives off resin under high temperatures. Over time, the wood will turn to a golden colour.
  • Larch is good if your wood will be exposed to wood eating insects. It’s quite a heavy wood and has a light shade.
  • Red cedar is one of the more sustainable options and has a slightly red tint to it. Red cedar doesn’t have a tendency to shrink and is resin free.
  • Oak is a premium choice; but it should be noted that oak has a tendency to absorb water which can cause it to shrink and absorb over time. Oak requires a lot of care and attention with annual treatments applied.
  • Thermowood tends to be a premium choice, as it has been put through a high temperature treatment process. This makes the pores of the wood close up and stops it from absorbing further moisture. It also causes the resin to evaporate. As the more premium option, the wood tends to be extra resistant to decay, rotting and warping under humidity. Surprisingly, it’s one of the lightest options and has a dark finish.

How should I maintain the wood?

We recommend that you apply suitable wood oil to all of the external and accessible wooden parts including the stairs, panels, lid, etc) twice per year, before and after the winter season. Check which oil is suitable for your chosen wood option, but we recommend using linseed oil for many of the types of wood in our options list. Panels can also be painted or stained.

Do you offer models which are flat packed for self-assembly?

All models in our current range can only be delivered fully assembled. We don’t sell any self-assembly hot tubs. This keeps things simplest for our customers with minimal setup time required.

What diameter hot tub should I select?

Our fiberglass models are available in one size only with a 1.8m internal diameter. These can accommodate up to 6-8 people, depending on the design.

What is the difference between internal and external heater models?

We’ve written up a full section on our wood fired hot tubs page on the differences between the heater models, and you can always refer to our product pages for the main differences. However, the main difference is that interior heaters have a lower heat loss, as they are submerged into the water, whereas external heaters suffer more from heat loss. The integrated burner design, where the burner is fitted between the fibreglass and wood, is a good compromise between internal / external options.

What is the optimum hot tub water temperature?

We recommend a temperature of 38˚C, but this does come down to personal preference. Those with any pre-existing health conditions should always be extra cautious and seek professional advice before using a wood fired hot tub. It should be noted that as these are heated naturally, that care and attention should be used to ensure that the temperature stays within safe limits.

How long does it take for the hot tub water to heat?

The heating time does vary, as it depends on the outside temperature, water temperature, heater type, etc. However, as a guidance in the summer, you can expect a 1.8m hot tub to take 1.5-2.5 hours to reach a comfortable temperature.

Can I use chemicals in my wood fired hot tub?

Our standard, default option heaters are made from 430-grde stainless steel. You should upgrade the heater to 316-grade stainless steel if you intend to use chlorine, bromide, saltwater or any other chemicals in the water. If you do use these chemicals in the 430-grade heater you will likely wreck your hot tub and will quickly experience degradation of parts. The retailer and manufacturer will not accept any liability for misuse of chemicals.  

What kind of heater should I use?

As mentioned in the previous answer, ensure you upgrade to the stainless steel, 316-grade heater if you plan to use any chemicals or salt water.

Do you offer any chemical free filtration options?

We offer the INTEX sand filter as an optional extra which will help keep the water clean and clear.

 How often do I need to change the water?

If you’re not using filters, chemicals or salt water cleaning, you should be sure to change the water at least twice a week, but potentially more depending on use. If using filters and chemicals, you should follow the guidance of the manufacturer and ensure that the water is changed as required.

Do I need to drain the water after each use in winter?

If there’s a chance that the temperature will drop below freezing, we strongly recommend emptying the water after use to ensure that no components are damaged if the water freezes. Note that:

  • If the stainless steel heater option has been included, salt may be added to prevent the water from freezing.
  • Electric hot tub heaters can be left running with the thermostat set to a low temperature to prevent the water from freezing.

Can I use my hot tub all year round?

We encourage you to! Just make sure that you take care of it in line with the manufacturer’s recommendations.

How do I fill the hot tub?

It’s super easy! Just use a standard garden hose lowered into the hot tub and fill it up as you would do a paddling pool. We offer an optional extra stainless steel water inlet connection which comes with a ball valve for filling the hot tub. This can be installed on the side panel of the wooden hot tub.

 How do I empty the hot tub?

Each model has a different draining system, but they all work in a similar way. For the integrated heater model, an external water tap is installed near the heater. Other models have a syphon and plug which can be upgraded to drain outlets on request.

Where is the air / water spa hardware installed for hydro / air massage models?

For our fibreglass models, the pumps are hidden in between the fibreglass shell and the wood panels, for a sleek finish. If ordering a sand filter, these are larger units and will be located externally and require a 0.8m2 wooden box to cover them.

Do I need professional help installing the electrical equipment?

For most equipment no, and we try and make everything plug and play where possible. Hydro / air massage pumps, filters and internal hot tub LED lighting comes with standard UK plug sockets, which simply need plugging into an outlet.

If an electric heater is an optional extra for your hot tub, they can only be installed by a certified electrician. The heaters are available in single phase 220V, 3 phase 230V or 380V, with a fuse box included. During installation of the electric heater, the black cable needs to be hard wired to the appropriate power source by the electrician.

Do I need to prepare any foundations for the hot tub?

In most cases no, but make sure that the ground can bear the load of the tub and water and most importantly that it is on a flat surface.

What is the estimated lifespan of a wooden hot tub?

The wood fired hot tubs can be used for 10 years plus, if the right care and attention is given to them.

Should I choose an air injection massage system or an air / water mixing system?

The air injection system provides a gentler massage effect and is made up of 12 nozzles installed into the hot tub. It has the added benefit of providing some circulation to the water to dissipate the heat. For a stronger massage effect, we recommend the air and water injection massage system. This system has 6 chrome nozzles.

Most people opt to not include a massage system at all, especially if they are not intending on hooking their hot tub up to electricity or it’s impractical to do so. If you want to be at peace with nature, not having a massage system installed is perfectly acceptable.

I’ve opted for the external heater option. How is it connected to the hot tub?

The external heater model is connected by two stainless steel pipes of 50mm diameter which are installed into the side of the tub. The heater is then connected to the pipes using two 1 metre length heat resistant hoses. It’s super important during installation that you make sure that the hoses are installed to be as straight as possible and the lowest hose should be completely parallel to the ground and level, it should not be at an angle.

Can I control the water temperature?

For log burning tubs, the water temperature should be monitored using a thermometer and by restricting the amount of wood placed into the heater. If necessary, it can be topped up with cold water.

If you opted for an electric water heater, it comes with a thermostat which will allow you to control the temperature.

What type of firewood should I use in my log burning heater?

Be sure to use dry and dense firewood which is calorie rich to ensure that you get maximum efficiency. The best types are oak, alder and maple, typically. It’s also possible to use biomass fuel bricks in the heater, but you should ensure that coal is never used as this can damage the heater.

What is the lead time for getting my hot tub?

The lead time is typically 4-8 weeks as hot tubs are made to order. The lead time tends to be on the lower end of this estimate during winter, and the upper end in summer. Hot tubs will subsequently be delivered once they have been satisfactorily tested.

What type of payment do you accept?

When using our checkout on our website, you can use a credit / debit card using our Stripe secure checkout, or you can check out with Klarna to make your payments over several installations. We also welcome bank transfers, contact us if you wish to pay using this method.
