Island Hot Tub, located on Whidbey Island in Puget Sound, is a pioneer in low volume outdoor soaking tubs. Since 1985 we have promoted the radical concept that soaking tubs should be part of everyone's life and not an expensive luxury. To this end, we have shown thousands of people how to create a simple soaking tub using a thermosiphon water heater.
The Chofu stove is a precision-built, high-efficiency 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 allows a soaking tub to be used in a variety of settings including remote locations.

We purchased a wood fired Chofu heater from Island Hot Tubs and set up a stock tank soaking tub more than ten years ago. Not only has the heater worked perfectly, but on the two occasions when we've needed parts over the years, Island Hot Tubs has provided speedy and friendly customer service. This is a first-rate company!

I bought this from you in 2013. Here it is in Nova Scotia firing up at 6:30 pm on September 26, 2020.
It has worked flawlessly since purchase and all plumbing you recommended for a 150 gallon RubberMaid stock tank is original - no leaks or problems.
This Chofu heater over-performs and if you can afford the quality don't hesitate to buy it.
We use a Honda pump to get water from the lake and next morning when it has cooled, back in the lake. No chemicals are required.
RubberMaid stock tank is perfect for two people and it works for horses & cattle too. The Chofu will handle a bigger tank but

We Found and bought this hot tub 15 years ago. We set it up with the basic 200 gallon stock tank, covered it with a hot tub cover we found out our local store and we’ve been using it all year round since then. This is an extremely affordable, durable and environmentally friendly option for getting warm any time. In the summer we use it as a cold pool. please do yourself a favor and get one today!

This hot tub heater has made an incredible difference in the enjoyment of our pool. In the beginning of the season kids can stay in longer and have so much more fun. I lost my drain plug and I called out and they dropped it in the mail the very next day. I had my Chofu heater for 15 years and it is still going strong.

Above and beyond. My Chofu from Island Hot Tub still looks/works great after eight years. It was originally installed it in a stock tank but a few months ago I transferred the heater to a copper tub. Years after I had been a buying customer, Frazer spent a ton of time patiently helping me, a non-mechanical person, to reconfigure the new set up. He also went over finish details with my contractor.
My Chofu is installed at a luxe vacation rental just inside Joshua Tree National Park (conventional electric spa not possible due to off-grid nature setting). Because use is mostly by first timers, tubbing

Island Hot Tub provided exceptional service. Frazer was very knowledgeable about the Chofu heater, installation and gave great advice for building your own soaking tubs. We greatly appreciate all the time he spent on the phone discussing our bathhouse project. The Chofu heater, stove pipe and connecting hardware are all great quality, come packaged well with no damaged or scratched parts. As for the Chofu heater, it is incredibly efficient and easy to operate. Works flawlessly every time. Thank you Island Hot Tub!!

I love my Chofu wood heater. The quality of construction, ease of use, and reasonable price makes this an easy choice for me. My unit has given me flawless service for over ten years, though I do caution to retire the hot tub system during the winter months if you live in a very cold environment as water does freeze and can damage the water jackets in the stove. Island Hot Tubs gives first rate customer service as well. Personal, friendly, and dedicated to supporting their products.
