warm water

hi

can anyone help.... i am wondering what the resistance should be on the elements for a polsicoil 2000?

i have got 17.9 oms...on off peck and 18.3 on peck i think this might be a little low?

19 ohms

do you think my readings would trip out stats and cause the water to be warn rather than hot?

thanks for your help

It sounds to me that you have non genuine heaters or stats fitted.
All the PC 2000 heaters and stats I fit have no safety stat.
As they are not needed (the safety stat). Being a thermal store and sitting with a temperature of around 72c.
The DHW temperature is carried out by the sensors 50c to 55c
If the bottom heater is sitting in too much sludge that can be a problem.
Or if the heaters are scaled up with lime scale.

I think it would be the stat as well. It should reach over 70oC
