Twin Thermostat Supply

[chloebear]

Hi,
Is it normal to run a twin thermostat imersion tank off a single time clock & single supply? My simplistic thought, not being a heating engineer, is that 2 supplies would be required in case both thermostats were used at the same time?

When you say twin thermostat, do you mean that or has it got twin immersion heaters?

Some cylinders have 2 heaters and are wired so that you can heat a half tank or full tank, you used to be able to get a top mounting heater that was marked sink/ bath, one was longer than the other.

Sorry, it is a new imersion tank with 2x 3Kw imersion elements in the side of the tank - 1 top 1 mid way

2 supplies is what you need, you could install 1 timer but you would need a contactor so it may be cheaper to install 2 timeclocks
