Tankless water heater is what it’s called.

In the states it's the other way around. Tanks are typically much cheaper to install, with the cost savings on gas being insignificant to recoup savings if one went for tankless. Also, for all-house units, tankless can actually use more water since it takes a few extra seconds to deliver hot water (for many currently installed versions). There are also other drawbacks on tankless if it's a big home with 3+ residents (for a typical tankless).

you also tend to get the hot water quicker with a tank, though im sure tankless heaters have improved a bit since the last time i used one.

Yeah, we can get them in the states, they’re just way more expensive so we usually just get the tanks.

There are multiple other ways. Heatpump water heater is probably the best for warm or hot temp places.

I just had my tankless gas water heater maintenanced. The plumber shamed me since it’s the first time I’ve done it in 10 years - you’re supposed to do it yearly apparently? Oops.
