Yes, the coolant is hot and under pressure so that makes the hoses hard.
Have you checked your coolant levels?Simply put, the heater runs by blowing past the hot coolant pipes and gives you warm air.
I'd be checking the oxygen sensors
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes

Coolant temp is about 196F. Mine runs cool on a highway, 2 notches below the red line on hot days in traffic.

You could just need to flush our your coolant pipes. Detach both hoses leading to passenger side firewall and spray into one of the pipes with a hose. It will come out the other pipe. This solved my problem in my '91 Ranger.
There are pipes that feed from radiator to radiator. Or there can be multiple feed pipes and return pipes, it varies based on installation.
