there may be an air lock in the cooling system
ther heater control may b not be turning on the control tap
the heater core may be blocked and not allowing coolant to circulate through it.
Anna, thermostats don't fail all that often. If you are overheating after a new one, the problem most likely resides inside the radiator. Radiators can get plugged with gunk over time if they are not flushed at least occasionally. Have you tried that yet?
Does the overheating happen while the car is moving or only when at idle for a period of time?
Is the coolant less than two years old? If it is more, I recommend replacing it after doing a cooling system flush.
If you still experience overheating after that, I recommend having a good radiator shop give it a look.
Flush system 2 times with new thermostat make sure you buy proper one. Check level and colour of coolant, and the oil. Milky is bad in oil. then flush sytem

disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec
Remove and raise upper hose at thermostat end and remove lower rad hose. Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily. Honda rads are cheap.....any restriction....replace rad.
Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose. Flush good.
Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.
Stop leak can plug everything.
Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW! Water pump is optional at this mileage.
