using PVC for a steamer for steam bending wood

[wood steamer]

Hi Everyone,
I want to build a boiler from PVC to make steam to bend wood. What is the largest electric heater element I can use to boil the water in a 4" PVC tube, and how long shoud the tube be? :confused: Thanks, wood steamer

Wood Steamer; you might want to check out this link, but with a name such as yours I wouldn't think you'd have to.
