| It's a direct flow heater - Panasonic 10XXX something - it is not really a shower as such, it is a "multi Point" water heater - and yes, you do not need 10KW for a shower - in fact it would probably cook me if I could bare to stay in the water on this setting.
The "heat" lights do not go off!, regardless of water flow - unless you slow the hot water flow to virtually a trickle, then the overheat cuts in. What I am trying to understand is - is it burning 10KW as long as the heaters are on?
For example - 100% hot water flow gives you for instance boiling water - using 10KW.
Then, I reduce the hot water flow by half - by switching the mixer tap to half hot and half cold (the flow rate doesn't change it's already at maximum) Where does the other half of the heat go? The machine still indicates that all three heaters are on - nothing switches off, so if it is still running at 10KW, with the same water flow, at half the temperature - where has the other 5KW gone? - or am I going mad? (I see no sign of a thermostat as this thing just gets hotter and hotter - the only thing that cuts it out is a severely reduced water flow) |
