General Knowledge on “Stainless Steel Coil Heat Exchanger for dutch tub,Wood fired hot tub heater coils ”

principle Wood-Fired-Hot-Tub-workingThe Firehot Coil Heat Exchanger works depending on the principle of natural hot circulation.  Natural hot circulation refers to: in a closed system,depending on density difference between hot and cold water,to form circulating liquid to drive an energy transmission. In the dutch tub coils,the cold water flows in from the bottom tail pipe,and goes up in form of spiral state,during this process,absorbing fire heat to let the water inside gradually become hot,and finally flows into the tub.During this cycle,the water in the tub becomes more and more hot…For DIY your own outdoor hot tub,please refer to this article.

The wood fired Hot Tub,used as hot tub heat exchanger, was just to utilize the Coil Heat Exchanger works depending on the principe of natural circulation to warm water to have a bath.

Without electricity or gas, you can enjoy bathing in a Wood-Fired Hot Tub in free and relax yourself at most.

This simplicity still appeals to many people. But also the rituals around it, like gathering the wood, burning the wood, regulating the stove and the heat, mixing the water up front. And then enjoy the rising steam and noises from the heater…….

In that respect a Wood fired Hot Tub is a total different product compared with the Jacuzzi from today which is working on electricity.

What is a Wood fired Hot Tub? A Hot Tub generally consists of the following components:

A heater / stove (made of stainless steel) being a sort of metal container below the water in which you can burn the wood. This heater has 2 openings that are above the water, 1 for air and landing with a wooden lid with wooden handle, and 1 for smoke exhaust. All our stoves are made of 2-3 mm stainless steel.

A chimney connected to the air pipe of the stove. This is a long metal pipe with a cap that serves as a spark arrestor.

A protective panel around the stove protecting you from burning on a hot stove.

Benches all around, so you can sit and relax. On request benches are removable for cleaning purposes.

Drink holders depending on the model attached to the cap of the stove, sometimes attached to the exterior. You can keep your drink or snack at a place holder.

A ladder, to be able to take place in the wooden bathtub.

A lockable wooden lid, Wood-Fired Hot Tub at the end when you can not use it. This prevents such leaves may fall, or insects get in the water.dutchtub-works

A stop so you can dirty water drains and evt. aanluitmogelijkheid one can achieve in the stormwater or sewer for dirty water.

Stainless steel around the Wood-Fired Hot Tub. This stainless steel straps are the rings around the Tobbe Tobbe which you can sue. Suppose that Tobbe has shrunk slightly in dry weather, you can tighten the straps slightly. On the stove side you can usually tighten the straps.

  6. I`m from Germany,and my coil heater arrived last month,and I used it with my own tub together to DIY built a wooden fired hot tub.Seems very nice and good looking. Thanks for Smartclima`s excellent coil,it is so good quality!

  7. Heater coil (Option 1) arrived yesterday and I’m really pleased with it. Communication from Johnhua was excellent throughout, air delivery to the UK was really fast considering it came all the way from China. No problems with customs or extra charges and tracked all the way to my door. Delivery guy thought I had ordered bagpipes.

    The reviews on this website really helped with my decision to buy so I felt I should share my experience. I’ll be installing this on an above ground swimming pool to supplement an electric heater, it’s 10.7m3 capacity so I’m not expecting anything close to hot tub temperature, but if I can get 4-5C increase over a few hours I will be delighted. Fingers crossed.
