Question about Cars & Trucks
Replace the thermostat, it might be stuck in closed position. Don't mix tap water with antifreeze, as minerals will cling on to your hot engine.

SOURCE: little heat from heater
I had the same thing for two winters couldn't get good heat then the HEATER CONTROL VALVE,
up near the master cylinder, cracked and started leaking. I replaced it this summer and now the heater is working like new.

Check the 'heater control valve'. This valve opens when u turn on the heat switch on the dash, so the hot coolant will flow thru the heater core and provide heat. So although the coolant is circulating in the engine, the valve controlling the flow to the heater core is stuck closed, or not working.

Replace the bad radiator hose first. Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator. Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it. Fourth- Check for leaks by looking for the colored dye. If it's not the radiator hose, then could possibly be a pin hole in your radiator. Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.
