[OpenTRV-dev] Storage heating, dynamic demand, and OpenTRV

Sun Sep 7 15:57:34 BST 2014


just on top of my head.... an well insulated hot water cylinder with an
electric heating element in series with the rad loop..? then both the gas
heater and the electric can heat up the water at the same time...

of course you have to wire in the electric heating element so the system
will not boil...

in denmark the cylinder normally hold 100 liters of water, not sure if
there are space enough in an UK home for that... but if you can get them in
50 liters you could pick 2 of them and place them where there is space

but will the gas heater make hot drinking water from that same loop? if not
my idea is not worth much....
