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 (not sold by EZ Shopper), 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.

Which wood options do you offer?

We only offer Thermowood panelling on our hot tubs, as we believe it provides the best resilience against heat and has a high satisfaction rate amongst customers. 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 colour, but we recommend using linseed oil for most unpainted options. 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 200cm or 220cm external diameter. These can accommodate up to 6-8 people or 8-10 people. 

What is an integrated burner and what is the difference between internal, external and integrated heater models?

We only sell integrated burner hot tubs at EZ Shopper as they are by far the most popular option. Internal / external heated options are also available from other suppliers. However, the main difference is that internal heaters have a lower heat loss, as they are submerged directly into the water, whereas external heaters suffer more from heat loss as they are not installed into the hot tub and are connected by tubes. 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 304-grade 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 304-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.

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 316 grade heater option has been included, salt may be added 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. 

How do I empty the hot tub?

An external water tap is installed near the heater. 

Where is the hardware installed for hydro massage models?

For our fibreglass models, the pumps are hidden in between the fibreglass shell and the wood panels, for a sleek finish. 

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 pumps and internal hot tub LED lighting comes with a short lead and UK plug. However, we strongly recommend that for long term use that an electrician helps to install a permanent solution.

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 a hydro massage system?

For a stronger massage effect, we recommend the hydro 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.

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.

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.
