Good thinking, Lynne.Lol, I explain better for the switches: We work on a project through European Commission on early diagnostic of depression. For that, we have series of people doing trials with ElectroEncephaloGram and ElectroCardioGram devices that DH developed. The devices need to be fitted with a switch to avoid they discharge when not in use. xx
We have ours on all day in the WWinter but we don't have a tank just a condenser boiler.
