You can use a ball or globe valve to add some cold water into the hot to adjust it to 130F or whatever. A local heating supply house would have the auto one which is safer and will change with the seasons. Shut off water to the coil, sweat in a ball valve into both the inlet and outlet and on the coil side a boiler cock on each. To clean it, shut both valves and flood it with a gallon of solution from the heating supply or vinegar if it's Fri eve and tyou want a shower before monday nite, then rinse it good. A female-female hose adapter from the hardware would let you run water through it with a hose. If your water pressure is not leaking into the boiler and lifting your safety valve you probably don't need a coil unless cleaning doesn't work. $500 is well on the way to adding an indirect water heater which is more efficient.
