Introducing the Heat Island (HI) vaporizer. A new approach to direct draw convective vaporizers. The heart of the HI is a ceramic heating element that is identical to the one in the Toasty Top and several other direct draw convective vaporizers. It operates from a 12 volt power supply and requires approximately 0.8 amps. The heating element threads into the bottom for easy cleaning / replacement as necessary. The HI uses heat island technology rather than a heat sink as with most conventional direct draw convective vaporizers. This means there is very little metal contact between the center stainless steel tube and the outer stainless steel tube. The HI uses as little metal as possible and is not able to transfer much heat away from the center tube out to the wood. Consequently, the wood stays relatively cool while the internal temperature reaches around 450F. The HI is 3-1/2" tall and can be as small as 1-1/2" in diameter. The internal stainless steel heat island weighs just 17 grams. There is a debris screen in the center tube as well as the space between the center and outer tubes. The HI can be made from virtually any wood as it has little impact on the final temperature. The power jack is located on the bottom of the unit. The right angled power plug is incorporated into the wood base so it sets upright like a conventional direct draw convective vaporizer. Since the HI has such a small metal mass, it will start producing vapor after being plugged in for only 5 minutes. It may take an hour before the wood will start to feel warm. It is also designed for 24/7 operation. The HI does not lose temperature after each draw and it can be used for near continuous operation. The HI can be used with two different roasting tube styles. It will accept 5/16" diameter (Toasty Tube and others) stainless steel roasting tubes inside the center tube as with traditional direct draw convective vaporizers. It will also accept my new 3/8" diameter (Turbo Tube and others) high temperature medical grade silicone roasting tubes on the outside of the center tube. The Turbo Tubes use a glass or polypropylene mouthpiece tube covered on one end with a section of silicone tubing that contains a stainless steel screen that is seated on the glass or poly mouthpiece as seen in the photo. The airflow is significantly higher than with the Toasty Tube. The HI is perfect for use with water filtration due to the low air restriction. The Turbo Tube fits perfectly into a 14mm glass joint. The HI is so small you can hold it in the same hand while pulling the Turbo Tube to clear. It may be small, but it is mighty. The HI does get you high. I will be offering them for $140 which includes the power supply. Exotic woods will be an additional $10. The Turbo Tubes are $10 and the new style Toasty Tubes are $15. Still deciding how I want to approach selling them. Contact me at firstname.lastname@example.org to make arrangements until then.
