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…

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.

    Sorry about messy you around like this, it actually came out pretty cheap to make the entire hot tub using your coil and good quality hard wood, which is annoying.

  9. M.Molavi says:

    I couldn’t express how much I like this coil. The tube is polished,looks very nice,and I feel the water inside can flow smoothly and “happily”. Ago,I had some troubles because of direct flames which burn my clothes when mixing up my potions. But now,with the indirect flame and wind and smoke shield, I can wear cloth leisurely,no worry other thing.

    Hi,I gout yout stainless steel heat exchangers coil samples.I`m pleased with them . Could your company make similar ones to a different size, to order ?
    I have joined the two I purchased from you and using them in an indirect heating system I have built to heat a swimming pool using a wood burner. I am thinking of perhaps marketing my prototype wood burner boiler and would need a purpose built larger heat exchange coil, with more turns and possible with a wider diameter. Has your company got the facility to make such variations to to the product I have purchsed from you?
