Oh yes. Sorry, that probably ought to have been obvious to me. It's one of those months.
Agreed. If you are using electricity for heating it probably makes sense to have the heating element locally, rather than having the heating element remotely heating some carrying liquid and then exchanging that heat in to a home or office.
What slightly complicates that is that there are some cases where you have an existing district heating scheme running mostly on waste heat or biomass but you also want to use electricity as either a back up or opportunistically to soak up over generation in a non-despatchable renewables heavy grid. In that situation you might be better off having 1 system inside each house, 1 system to carry heat from the heat sources to the housing and 1 or more systems putting heat in to that heat network.
