... forgot to say... the boost is the separate heating element at the top of the tank. That is on a separate switch and is working OK.
Interesting... perhaps I could rewire the power that goes to the boost element (that's known to be working) and wire it to the economy 7 (it will reach) and if it fails to heat then the the problem is with the economy 7 thermostat or element!!!!!!
