Rated 4 out of 5 by Good timer Straight swop for 15 year old timer. Plugged in no problems. Instructions for use looked complicated. I was wrong worked through them with no problems and its great that I wont have to change to summer time. Here's to another 15 years so we will wait for reliability to have more stars. 14 Jan 2016

Answer: 
The specifications state that the contact current rating is 3A, A typical immersion heater requires a minimum of13A, therefore this programmer is most definitely NOT SUITABLE. You should use a purpose made immersion heater time-switch.

I want to upgrade my old mechanical timer that controls HW and Heating. It has 5 wires but I am confused as to my options. Can I only replace with a 5 wire or can I use a 4 wire unit.

My system is gravity fed but i do have a shower pump, if that makes any difference.
