just leave the neutral wire as it is and connect the other two !!
if it is a 240volt motor it does not matter,
Yes the wire size is larger for that size breaker but will not effect the 30 amp breaker protection of that circuit.
A heater does not get hot enough to benefit from the expense of using tungsten wire. Most heaters use either wire made of an alloy called nichrome or plated ceramic heating elements. Heaters generally operate at red or orange heat (i.e. 1409F to 1908F) and can use nichrome wire. Lightbulbs operate at white heat (i.e. greater than 2309F) and use tungsten wire, but tungsten is hard and expensive to make into wire compared to softer metals.
But why do you want to connect them in series since this will under feed the heaters? I recommend that you connect them in parallel across the supply so that they each have 115v and thus provide good heating effect.

Ni chrome is a low resistance wire used in heaters and toasters.
Yes you can. As long as you don't use 40 amps. The 30 amp breaker may kick off if you use all things at once. So you are well protected but not up to code. The 4th wire required for the new stove is probably a ground fault wire. So run a new cable or cook slower.

Rheem provide a series of high efficiency gas water heaters. Several different companies also provide tank-less water heaters, which are very efficient, as well as solar water heaters.
Some are series, some parallel, some both. Depends on the design. Series heaters will have all the heaters fail or shut off should one burn out or open circuit. Should a series heater short out the other heaters will see increased voltage so must be able to handle full voltage or they will overheat and fail. Parallel heaters will not notice if one of the others open circuit. If protection devices, such as fuses or overloads or overtemp, are installed for each heater all others will continue to operate if one shorts out or fails. Parallel heater designs are more common.
Yes, kerosene heaters are safe for indoor use, such as the Mr. Heater F215100 Portable Buddy Series, which is certified for indoor operation.
Most baseboard heaters use hi voltage thermostats.
It is nearly always Nichrome wire. The same is used for space heaters, etc.
