We're only 11 days in but here's the cost for keeping our conservatory (glass roof) at 19 degrees for the last week - that's an average of 51p that we're more than happy with.....My post was at a 'consider' stage but I subsequently decided against this prior to reading your reply.
I've also looked at a freestanding infrared heater panel because my wife is often at home for several hours during the day, mainly in the open plan kitchen-dining-conservatory area. Maybe I will try one as the cost is relatively low & it would be powered from overnight battery storage plus any winter solar generation on cold sunnier days.
I realise this isn't portable or meets your brief - but for anyone else interested in one!
