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

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.

Want to enjoy an outdoor hot tub with a wood fire coil heater (as picture shows)? For many people, this is a romantic, luxurious and inaccessible lifestyle. However, this is possible to DIY a hot tub like this and it is not difficult. So in the following article, we will share more comprehensive steps for DIY a wood burning hot tub. Hope it is helpful to everyone.
First, prepare the following materials and tools:
A bathtub. You can get a bathtub from various channels, you even can also use an old bathtub to retrifit it, or you can use wood pieces to build a bathtub yourself.
Some copper pipes and stainless steel tubes and water tank connectors.The diameter of copper tube should be bigger than 19mm in order to have a good heating speed.
Prepare a drill for drilling holes on the bathtub.Alternatively, you can add an optional drain plug to the side of the bathtub near the bottom so that you can easily drain water as needed.
The following steps you can follow:
1. Choose where to build the bathtub.From the simplest perspective, you must decide where to build the bathtub. If unsure, look for an area that will not affect the house or its light at all, preferably near to water.
2. Prepare the ground.Once you decide where to build your bathtub, you need to level the ground and remove things like spikes that could damage the bathtub. Then place the bathtub on that flat ground.
3.Make a heating coil. You can use copper tube to bend to be coil to heat the water in the bathtub. Or you can buy a good Stainless Steel Coil Heat Exchanger for dutch tub directly from Smartclima, it has a more reasonable design, it heats up faster, and it looks more beautiful.
4. Drill holes on the tub or tank.Use a drill to make holes next to the bathtub or water tank. The size of the hole should match the size of connection kit. The position of the hole should be determined according to the position of the inlet and outlet pipe of the heater coil.
5. Add accessories. Put the water tank connection fitting through the hole and sealed it with a silicone sealant. Then connect the heating coil and bathtub connector with a high temperature resistant water pipe.The ends of your own heating coils may be slightly bent, so trim them before inserting them into the accessory. Put some bricks under the coil heater so that the height of the coil is consistent with the height of the bathtub hole.
Done. Then fill the bathtub with water and burn wood in the coil. Note that the height of the water in tube should be higher than the opening hole in the bathtub, this can greatly shorten the heating time.
It is recommended to use plastic bathtubs or wooden bathtubs, as this will help to save wood.
Creating a stove-like enclosure around the coil will make the system more fuel efficient and help draw the smoke out of the barrel.
If the cost allows, it is recommended to increase the number of coils, which will speed up the heating.
It is recommended to use larger diameter copper and stainless steel pipes to increase the heating rate.
