Stepwise control

Boilers can be very effectively controlled if a few carefully-chosen values can be easily selected. One way of doing this, half-wave rectification, is an antiquated technique that definitely violates power regulations. The remaining methods include using multiple heating elements in various combinations, selecting between multiple voltages, or a combination of both techniques. Selecting multiple voltages is only possible in some countries, and having multiple voltages available in a single outlet creates a potential accident situation, so we do not recommend it.

Before we show how to design and build a reliable, multi-step control system, we need to discuss some electrical theory, so you can tailor your system to your needs.
