Possible to make 2015 Camry heat hotter?

So my last car’s heat was hot. Very, very hot. Bought this 2015 Camry XLE and the heat is just lacking. I don’t know why but I still wonder: is it possible to make it hotter. I read something online that mentioned changing the thermostat would do the trick, but I know nothing about cars so I don’t know how true that is. Can anyone here shed some light on whether or not it’s possible and if it is, what exactly needs to be done? All comments and opinions are welcome. Thanks.

    There are a number of things that could cause this, such as an iffy thermostat, a partly blocked heater core, a faulty heater control valve, or even the coolant level being too low.

    So you'll have to approach these potential problems one by one.

    The easiest would be to check coolant level.

    I don't recall how hard or easy it is to access your car's thermostat on that model. It can be taken out and test on the stove top, in a pan of boiling water, or you can just replace it and take a chance that that's the problem.

    A clogged heater core would require a reverse-flush and you may be able to access videos on YouTube to show you how to do this, or take it to your local garage.

    A bad heater control valve often requires partial disassembly under the dash (unless you are lucky enough to have a model with the valve in the engine bay, in plain view) and you may want a professional mechanic to tackle that one.

    Here's a discussion of how the HVAC system works in a car:
