Everytime we finish using the oven we leave the door open to warm up then close it when cool down. 22C yesterday and 20C this morning. If you aware that flat tv emit warmth when I experienced one staying in London hotel as we dont have one yet but planning to get 2 so one for bedroom and living room for YouTube and Netflx only as we dont use TV Licence. If that does help to warm up mean heating wont be on often this coming winter. My current 2 all in one desk top computers give the living room around 1C warmer. TV and PC does not use much electric. All switch off at night as always or when we go out.
If you're on electric heating, it doesn't make much difference whether the heat comes from an oven or a fan heater if the wattage is similar. But the fan heater would be expected to distribute the heat around better, not let it all convect up to the ceiling - and gas is cheaper by a long way, so use it if you have it, assuming you don't have worries about fossil fuels.
I don't think the TV solution is on. As you say, TV & PC don't use much electricity, about 120 -150 watts. In my experience in a reasonably well insulated house when the gas boiler broke down, about ten times that was needed to keep a living room comfortable in cold weather.
You could always go back to 'when I were a lad' and plan for ice on the inside of bedroom windows to save energy. It was a common experience in the 1950s.
PS. For comparison, the resting human body produces about 100 watts of thermal energy, so pack your house with people. A party every night!
