[QUOTE="Borwick, post: 286653, member: 20933"] A very interesting thread as I am planning something similar. Top of the list, I was thinking about acquiring a site transformer to drop the voltage on my immersion heater to 110v. The advantage being that if it doesn't work well then I can just put it back on eBay. Does anyone have any views on the specification of site transformer which would be best to work with a standard 3KW immersion heater element? Now, I am just a country boy and would welcome some help, However, I remember P = I.V and it occurs to me that if I use a transformer, then the power in will be the same as the power out, save for some percentage loss and heat etc. So, even though I have changed the voltage of the supply to my immersion heater the power will stay the same but the characteristics will change so there will be more current drawn by the element. Am I right about this? If so, transformers won't help us when trying to reduce the power consumption of an immersion heater. The other route seems to be to use an electronic solution to "chop up" the AC current so that only part of the power is available to the immersion heater element. I have heard that such solutions can cause problems with other sensitive electrical equipment nearby. Has anyone had any bother with this. many thanks. [/QUOTE]
