Heaters and More

Electric Heaters

Most hot tubs use electric heaters.  Compared to gas, electric heaters are less expensive and easier to install.  

The SmarTouch electric heater is programmable and features automatic temperature control, filtration cycles, overheat and freeze protection,  quiet-time, and more. This is a dependable way to heat most tubs in most climates.  A digital touchpad allows the heater to be controlled easily from beside the tub.

Available in standard 5.5 kilowatt size or upgrade to 8.5 kW for faster heat times.  For a soaking tub this is a simple and quiet system. This system can be ordered with a set 4 jets for additional cost.

This heater is UL listed for safety and compliance with all building codes. It features top quality components that provide automatic temperature control, heating and filtration cycles, automatic water quality (when used with UV water purifier), dependable operation, and easy installation.

The SmarTouch Digital 1000 comes with a two year warranty. It can be owner-installed except for the electrical connection which must be done by a qualified electrician.

The controller, heater and pump are pre-plumbed, wired and mounted on a 28" x 16" skid. If the SmarTouch system is installed where it is exposed to any rain or snow, it must be protected with a cover.  The optional cover (shown below) is the easiest way to do this.

  • Electric heater with digital controller for tubs with jets
  • 5.5 kilowatt electric heat (upgrade to 8.5 kilowatt available)
  • Digital touch control panel accessible from tub side
  • Single speed spa pump for circulation (or dual speed pump for optional jets).
  • Heater, controller and pump pre-plumbed, wired and mounted on 16" x 28" skid
  • Programmable features: temperature,four filtration cycles, time out, freeze protection, temperature calibration
  • Weatherproof cabinet available for exposed installation

Gas Heaters

Gas heaters are a good choice for larger sized tubs or cold environments that require more heating power.  Gas heaters are more aggressive and faster than electric heaters, and are available for natural gas (NG) or propane (LPG).  We use the new efficient 105,000 BTU gas heater made by RayPak (larger sizes available upon request).  

Along with the gas heater, we add the SmarTouch Digital controller to manage the temperature, filtration, scheduling, and other functions.   

This system is UL listed for safety and compliance with all building codes. It features top quality components that provide automatic temperature control, heating and filtration cycles, automatic water quality (when used with our UV water purifier), dependable operation, and easy installation.

The SmarTouch Digital 1000 comes with a two year warranty. It can be owner-installed except for the electrical connection which must be done by a qualified electrician.

Digital touch control allows the user to program the temperature, 4 separate filtration periods, quiet-time black-out periods, timeout to turn off jets after use, automatic freeze protection, time of day clock, and temperature calibration.

Chofu Heater - Wood Burner

The Chofu heater is a precision built wood-burning water heater designed specifically for hot tubs. It circulates water using the principal of thermosiphon (the pumping action created by rising hot water), eliminating the need for a circulating pump or electricity. This heater is a simple solution to the problem of heating a natural soaking tub. It is ideal for those who want to heat with wood and works well with small or medium sized tubs. Great for remote cabins!

The stove body of the Chofu is made with high quality stainless steel, grade (316), so it can be used outside, without worry. And since the firebox is also made of stainless steel, it will withstand years of service without danger of burning-out. The smoke outlet on the Chofu features a unique vented collar that provides secondary combustion of unburned gases, for reducing smoke emissions and chimney sparks.

The Chofu utilizes a sophisticated heat exchange design for efficient water heating. The stainless steel stove body surrounding the firebox is a double-walled water-jacket with a 1-inch space between, making the entire firebox (except the front) a heat-transferring surface. Additional heat transfer takes place in a water-filled baffle plate that runs horizontally through the firebox. The baffle deflects the path of the fire, so it gives up more heat into the water jacket before going up the chimney.

Imported from Japan.

Operation
The Chofu operates like a conventional wood stove, achieving its fastest heating rate from dry hardwoods. It uses 17-inch wood with an 18-inch x 14-inch x 10-inch firebox. The most efficient heating comes from using small pieces of wood, loaded at 45 min. intervals. The Chofu has a high and low speed draft control to regulate the heating rate.

Heating Rate Information
Although the heating rate is variable depending on dryness of wood, frequency of loading, etc., the average heat output of the wood heater is 32,000 BTUs. A 200-gallon tub can be heated at approx. 20°F per hour.
