I = W/E. 1500/240 = 6 amps for each heater. In parallel the total connected load will be 12 amps. A #14 conductor is rated at 15 amps and de rated to 80% can carry 12 amps continuous. The breaker needed for this would be a two pole 15 amp breaker. If this is a new installation I would use a #12 conductor for the two heaters on a two pole 20 amp breaker. The conductors will run much cooler using a larger size.
A circuit breaker is not a test instrument, it is a kind of switch that interrupts the supply when that is needed, but it is more than that because circuit breakers are specialised items, and examples exist that can interrupt currents of hundreds or thousands of amps at very high voltage.
The main items required for an electrical panel include the panel box itself, fuses, and wiring. The wires are fed into the box and attached to a series of circuit breakers to allow electricity to be directed as needed.
Not always. Depends on the circuit.
Appliances have to be connected in a parallel circuit to keep the voltages the same for each appliance (they were designed to work with one voltage) , this does not mean that the power output will be the same, the more appliances there are the more current (i.e. power) will be needed to for the appliances and this can go on until the grid cannot supply any more (and you blow a fuse)
A voltage supply is needed to operate a circuit.
The size of the breakers depends on the voltage. According to the NFPA electrical standard (USA), if the two heaters you describe are "120 volt plug-in" then they are not allowed on the same circuit. Two circuits are needed. The largest general use circuit allowed for 120 volt receptacles is 20 amps and this will not handle your two appliances. An exception may exist if they are hard wired to a dedicated circuit, or if they are 240 volt.
First question would be did it ever work ok. If not it could be undersized or a repair is needed. Fuses, circuit breakers? Coils clean and filters clean?

All the branch circuits in your house are parallel. They have a constant voltage applied to any device plugged into an outlet. If you thought about an analogy for a parallel circuit, imagine that the rails on each side of rungs represented the hot and neutral wires of a typical household branch circuit. The rungs would be the loads connected in parallel. Each "load" draws the current needed to operate the specific device. The sum of all the currents for the "loads" is equal to the total current being supplied through the circuit.
because the circuit you have quoted is a parrallel type, the voltage will be the same across all the components/ resistors in parallel . -- 78 volts. however i wonder if you needed to calcualte the current flow
It is very beneficial to have a parallel circuit... for example: 1. If one light in a parallel circuit goes out, the other light bulbs will remain lit Whereas if a light in a series circuit goes out, all bulbs will go out 2. If not all light bulbs are needed on, you can turn them off with the remaining light bulbs staying on

Yes, the tankless water heaters do cost more than the normal water heaters because tankless water heaters are designed to supply hot water only when needed unlike normal ones.
Tankless water heaters are low energy because they only run when the hot water is needed.

The electric furnace operates on 240 volts so a two pole breaker is needed.
