I'm a beginner to electronics, but i have a good amount of experience in mains power so i'm safe on my execution.
I'm wanting to heat water to a certain temperature in a closed loop (the water is recirculating). My initial plan is to use an immersion heater and pump water through it, in the UK - 240v, 13Amp max, although i am open to suggestions.
I plan to have a temperature sensor on the output side of the immersion heater, and would like to control it to within a few degrees. I could simply use a heavy duty relay and switch it on and off, however i don't think this will provide the level of control needed, the water will either be too hot or too cold too quickly.
I'm not sure if using a triac would be better, and i can rapidly switch the immersion element on and off? I've been using this as a reference:
Any advice would be greatly appreciated.
