[QUOTE="ProDave, post: 251103, member: 6969"] There are two ways of doing it. It sounds like the old cylinder had two heater elements. The bottom one is energised over night to give a full tank overnight at the cheap rate. The top one is energised by the timer as and when needed for a top up. It sounds like the new tank only has one heater element. You CAN use most boost controllers but you need a bit of rewiring. Assuming it's a normal Horstman boost controller, you should have one permanent feed and one off peak feed into the controller, and you can rewire it to use the same heater for overnight, or daytime boost. The wiring diagram should be inside the boost controller. If it's not a Horstman, post a picture and model number and between us we will see what we can dig up. [/QUOTE]
