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

[Bo Herrmannsen]

hmm... just because i dont know, but are there gas central heating units
that also have build in eletric heating? if so that would be ideal

i only have an obscured view in my head that most british homes are SMALL
compared to what here in denmark at the same price level...

our flat as example... 87 square meters take a bit off for the different
closets etc... but roughly we pay 480£ a month, this even includes the
garage if not it would have been 30£ lower...

but here the space is limited to one utility closet.... and we are not
allowed to change anything there anyway...
