Why Buy A Wood Fired Hot Tub Instead Of An Electric One?

We think there are lots of reasons! Very low running costs, when not in use simply drain the water out, clean the bathing area and clean the ash out. Then the next time you wish to use the tub simply refill and heat again.

They look beautiful and are stylish and different to the many electric hot tubs and spa pools out there. Their innovative design is attractive and built to last, using traditional and modern materials for the best efficiency and stylish or contemporary looks.

There is also the theatre and fun of using wood rather than electricity, and the water you bathe in is fresh. It also broadens your options for where you have your hot tub, as long as you can get water to it you can choose your ideal bathing spot.

An increasingly popular option is to add an elecgric heater in conjunction with a wood-fired heater. This gives the fast heating capability of the high kW output wood-fired heaters but the convenience of electric to maintain the temperature. Please ask

Kirami, based in Finland, have been designing and manufacturing hot tubs since 2001 and produce over 10,000 units per year. As their leading UK importer we know a lot about them and pass this knowledge and support on to all our customers.

How Long Does The Water Take To Heat Up?

This depends on the burner and tub size, as well as the temperature of the water used to fill the tub and the outside weather conditions but typically it takes 2 to 3 hours to heat the water to the desired temperature of 38C. On a warm day with a light breeze and some gentle agitation of the water they will heat up faster. You can control the temperature by regulating the amount of wood added and the air supply to the heater, no forgetting that there is always the option to add further cold water from the hosepipe.  The tub needs to be filled at least 5 cm above the upper connection pipes of the stove before lighting the fire in the stove. The tub stove must never be lit when the tub is empty or not full. Heating a half empty tub will lead to melting the stove. You must not start emptying the tub before the fire and embers have burnt out completely. Heating a half-empty tub will lead to melting the stove.

How Many People Can I Fit In My Hot Tub?

It depends on which size tub you choose. The Cozy, Woody and Breezy tubs seat 4 to 6 people, whilst the Family seats 2 to 5. The Woody Tiny and Tiny seats only 2 people. It also depends how cosy or spacious you want to be.

Do I Need To Treat The Outside Of The Hot Tub?

We would recommend visiting the Kirami website where you can find specific user manuals for each type of hot tub which will tell you how to look after your particular hot tub but in short, a thermowood tub should be treated with an UV-protected water-based wood oil like Teknoshield 4015 at least once a year to maintain the beautiful brown colour. Red cedar tubs will go grey over time so it is best to treat the exterior with Textrol from Owatrol when necessary. ProfiLine composite and EcoPlank do not require any treatment.

How Do I Keep My Tub Clean?

Take care of the cleanliness and hygiene of the tub by washing it carefully and often. Drain the water and wash down the surfaces with a hose pipe or high pressure hose. It is best to use a product like Ecover Multi Surface Spray Cleaner which is naturally-derived and biodegradable.  After emptying and cleaning the tub, leave the drain tap open to allow water to drain off the pipes. A wood fired hot tub is usually used differently to other types of hot tub, as users fill the tub, use it 2 to 3 times and then drain the water. With this short term use there is no need for chemicals which is a great advantage to people who want a chemical free hot tub experience. If you want to leave the water in for a while then it is advisable to fit a filtration system and sanitise the water.

What Access Do I Need To Get My Hot Tub Into Position?

We need access of 2m width to deliver your hot tub, if access is tight it is possible to turn the hot tub on its side but we would still need a minimum of 1.2m width and then a clearance of 2m in height.

What Type Of Fuel Can I Burn In The Burner?

Only dry firewood or logs. Do not use any other solid fuel.

Do I Need To Build Any Part Of The Hot Tub?

No, the great thing about our hot tubs is they come fully assembled and as soon as they are in situ and the parts connected together, they are ready to go. Please see our installation guide above for further information.

How Often Should I Change The Water In The Tub?

In domestic situations it is recommended to empty the water every 2-3 uses. If it is used by multiple people then it is best to change it daily. If you want to leave the water in for longer then we recommend fitting a filtration system or using a sanitising treatment.

Is It Easy To Drain The Water Out?

Yes, simply open the tap at the bottom of the tub and the water will flow quickly out. You can attach a hose to direct the water to use on your garden if you so wish. We are able to supply these hoses in 10m lengths.

Will The Water In My Hot Tub Still Be Warm The Following Morning?

Yes, it holds the heat very well with the lid on and would only require a short time of additional heating in the morning.

What, If Any, Site Preparation Do I Need To Do, Before My Tub Is Installed?

The ground should be level and firm, so that it can support the tub when it is full of water. There must be an airing gap of between 3-5cms between the ground surface and the base of the barrel if it is a solid timber barrel.

Our most popular Kirami plastic interior tubs have an ABS base which can sit on decking, paving, thin and small gravel or any firm, level surface. If siting on decking please ensure there is a hearth plate in front of the heater door to avoid ashes and embers damaging the wood.

External heaters are raised off the ground by 5 to 10mm and are perfectly safe to be sited on decking. The raising of the heater prevents heat from leaching out of the bottom of the heater into the ground.

Sanitising Your Hot Tub?

If the hot tub is used frequently then it is advisable to sanitise your hot tub. It is best to use a non-chlorine shock treatment for domestic use. A shock oxidiser used once a week helps prevent bacteria and cloudy water. It oxidizes the water and helps to get rid of organic matter like dead skin cells, perspiration, urine and cosmetics. Treating with Oxygen is better for the tub than Chlorine or Bromine as the wood is an organic material and will become damaged with an overuse of these products.

If like many of our customers you will be using your hot tub for commercial purposes, it will be necessary to use a chlorine water treatment as part of the regular maintenance and good practice to ensure a safe and pleasurable bathing experience. Mindful of the increasing popularity of wood fired hot tubs in a commercial environment, we are pleased to offer all commercial customers the opportunity to take part in a training course which is held twice a year in the north of England. The course will provide the delegate with a Commercial Hot Tub Operator Certificate and is in line with HSE Health and Safety Guide HSG282 and the PWTAG code of practice.

Water pH Important For My Tub?

The recommended pH for your hot tub is between 7.2 and 7.8. It is advisable to test your water with some test strips as you can add additives to increase or decrease the value. The pH range is from 0 (very acidic) 7 is neutral and up to 14 (very alkali.) If your water is too acidic, it will corrode your tub and irritate your skin, if it is too alkali it will cause stains and deposits on the wooden tub, cloudy water and be drying to your skin. The pH needs to be within range for the effective use of other chemicals and safe bathing.

How Frequently Do I Need To Empty The Ash From The Burner?

Ash can easily be emptied using the shovel provided. It should be emptied when the water is changed or after the fire has gone out.

Is It Very ‘Smokey’ From The Fire?

No, there is only some smoke until the fire gets up to its optimum temperature, then as long as only dry wood is burnt there is very little smoke, just enough to give it the romantic atmosphere.

Where Can I Get My Logs From?

Simply order them from us at The Log Company and we will deliver your logs and firelighters at the same time as your hot tub. We can then continue to supply you throughout the year.

We are happy to quote for commercial situations such as holiday cottages, lodge parks and glamping. Please contact us to discuss.

Technical Info For Easy, Family And Comfort Range

It is important to place the tub on an even surface that can bear the whole weight of the tub. The foundation can be evened out with chips or it can be cast of concrete. In a partly EPS-based tub, any runs should not be installed beneath the base as the tub’s base needs to be on an even surface, which is completely load-bearing.

When placing the hot tub consider possible places to drain water to. If needed you can lead off the water with an outlet hose. The water discharge valve is located on the opposite side of the stove to which you can attach Kirami outlet hose. The hose has 38 mm inner diameter. Take fire safety into consideration when placing the hot tub. Always ensure that the chimney is located away from flammable materials.

Remember to check the distance both sideways and vertically to avoid the risk of fire. During wintertime do not leave the water unattended, in case there is a risk of sub-zero temperatures. You can either drain the water out of the tub or maintain a sufficient heat. The bottom plugs and exhaust valves need to be left open so that any water collected in the tub will discharge. Before lighting up the hot tub’s heater, always remember to check the water level inside the tub. The heater must not be lit when the tub is empty or the water level is below minimum fill limit. You must not start emptying the tub before the fire and embers have burnt out completely.

The minimum fill limit is marked on the heater and in the instructions. In order to keep the hot tub clean you can buy a model-specific cover. You can also take care of the cleanliness and hygiene of the tub by washing it carefully and often. Washing can be done, for example, with Ecover Multi Surface Spray Cleaner which is naturally-derived and biodegradable or Kirami Biowash. Kirami also sells chemicals that can be used for keeping the water clean. When using chemicals, the pH of the water should always be monitored and kept in the given limits, i.e. 7.0-7.6. The diameter of the chimney is 150mm and its length is 2m.

Technical Info For Woody Range

It is important to place the tub on an even surface that can bear the whole weight of the tub. The foundation can be evened out with chips or it can be cast of concrete. We recommend placing some boards or planks on top of the base because when the bottom of the tub is clearly in the air, it airs well and dries. It is also important to ensure that the tub is not covered by grass or hay, as it will prevent the wood from breathing and will cause rotting.

When placing the hot tub consider possible places to drain water to. If needed you can lead off the water with an outlet hose. The hot tub’s outlet is located under the hot tub near the heater and the outlet’s inner diameter is 50 mm. Take fire safety into consideration when placing the hot tub. Always ensure that the chimney is located away from flammable materials.

Remember to check the distance both sideways and vertically to avoid the risk of fire. Note that the discharge valve should always be left open in an empty tub so that water gathered in the tub can run out. During wintertime do not leave the water unattended, in case there is a risk of sub-zero temperatures. You can either drain the water out of the tub or maintain a sufficient heat. The bottom plugs and exhaust valves need to be left open so that any water collected in the tub will discharge.
