It really depends a lot on the house design. Like how my neighbors have a $400/month heating bill and I have a $25/mo heating bill. I weatherized my place and added better insulation. They live in a breazy improperly insulated home in comparison. There's also how much solar radiation the house is able to attain during the day via windows. That makes a massive difference.

If you are retro fitting a solar heating system into an existing house, you must keep these things in mind, when you need to know the size. I've seen a few people use solar evacuated tubes hooked up to PEX piping that goes into their basement where there is a cheap inflatable pool from Walmart stuck into a wooden frame for added durability. It is 12'/3.6 meters wide and 30"/76cm deep. It heats their entire home in a moderate temp zone. Theirs isn't thermosiphon, it uses an electric pump and fan both hooked to the thermostat.

That's an interesting way to store thermal energy. It is constantly being lost though. No wonder it takes up so a large area.
