Want to set up a floor heating component

My partner and I have been talking about getting radiant floors in the house. Our boiler idea works superb as a heater, however the two of us kind of love the idea of heated flooring. To make sure the two of us love it and it is worth the expense, the two of us are only going to do a single room first. The argument right now is over what room is getting hydronic heating. I want to do the family room floors and my partner wants the garage. I recognize the family room should get hydronic heating since the tile needs to be fixed in there anyway. Also, the family spends a lot of time in there for meals. The family room with the tile feels love the coldest room in the apartment too. There is also the idea that I use that room the most and would legitimately love the furnace in there. My partner wants the garage because our cars are in there. He hates getting into a cold car and running the furnace beforehand. With the heated flooring, the car would already be warm. He also works a lot in the garage. Having heating in there would be beautiful for him. I know he secretly wants to make that space his man cave. So who gets the hydronic heating system? He’s hardly in the family room and I don’t use the garage. So whatever room the two of us pick, the other a single won’t get to care about it at all. Maybe would should comprise and do the family room or something. That carpet is brand current though. So maybe that would not be the smartest option.
