I think they want more than 18c. 18c is pretty cold to sit in for a prolonged time.

At 18C I wouldn't even put on a sweater. People need to stop being so wimpy. 10C is a good target temperature during the winter.

Great, just need to get fat.

Get a heat recovery exchanger. https://natural-resources.canada.ca/stories/spotlight-energy...

It's not something you just add. It's a capital renovation. Requires ducting. Tons of homes don't even have ducting.

And in similar vein, when was the last time you read the manual for a household appliance?

Both fair points.

I like to familiarize myself with any appliance I buy, so I tend to read the manual at least once. And yes, it's usually a waste of time. :)

The more we study it, the more we learn how harmful the air inside our homes is. That's why fresh air is key. Crack a window or two open. Buy an air monitor that monitors CO2 (good proxy for overall freshness), VOCs (sometimes these build up much faster than CO2), and PM2.5. If CO2 or VOCs are high, open windows more. If PM2.5 is high and coming from outdoors, turn on an air filter. Yes, this means your heating and c…

Yeah thermodynamics though; generation of electricity for that extra heat or cold waste heats up planet.
