About a month ago we replaced the heating coil in our 20 gallon hot water tank. Everything with it was working fine until now when we started to use the furnance. It keeps blowing out the fuse ( 15 amp ) on the circuit breaker. How do i know if its the heating coil on the hot water tank, the furnance or the fuse? Also, Is it hard to change a circuit breaker and is 15 amp the right amount or not for both the hot water tank and the furnance?

If you replaced it with the exact replacement heating coil you should be fine. You could replace the breaker, it may be worn out. Replace it with the same rating. If this doesn't do it you may have bad wiring or heating coil. Is your furnace connected to the same breaker as your water heater? Try plugging your hot water heater into a different circuit.

You need an electrician to determine whether a larger amp circuit breaker can be put in; sometimes two breakers are tied together. Don't just put a larger amp breaker in without checking, or you might overheat the wiring and cause a fire.
I don't think a furnace and electric water heater should be on the same circuit, two high usage appliances. Easy enough situation to fix in most cases, but not do-it-yourself.

MOST of the time, the water heater will be on its own 2 pole circuit and a furnace will on another single pole circuit.
MOST water heater circuits are number ten wire with 30AMP breakers but they DO vary and you should never OVER rate a fuse for the size wire or the equipment rating.
Probably best to check out the rating for the water heater on the heater itself. It is ALWAYS there on newer units (15 years) somewhere on the unit. It will tell you what maximum circuit protection should be.
Good luck.
