Propane heaters cost less to run per hour.
Yes, a propane space heater can be cost-effective as a supplemental heat source because propane tends to be more efficient and less expensive than electricity. However, the overall cost-effectiveness will depend on factors such as the price of propane in your area, the size and insulation of your space, and how often you use the heater.
There are a number of factors that determine where the plumbing contractor decides to install it. If it is a gas heater, it needs to be located where it can be vented to the outside. Typically the heater should be as centrally located as possible to facilitate hot water getting to all of the fixtures it is attached to. They will attempt to minimize the length of the piping runs. Takes less piping and less work to install.
Install a bigger water heater. This would only be efficient if you had a constant need for an increased volume and could bear the added cost of installing, operating and maintaining a larger heater. Or increase the temperature on the water heater so you use less to get warm water. This also has its practical limits, where water could be delivered to the faucet at a dangerous temperature (over 130 F), unless properly controlled. Or install another water heater in parallel, giving you twice as much hot water before it starts getting cool. Larger facilities may have three or more heaters in parallel and another one in series for pre-heating the supply to the others.
a direct vent water heater is more fuel efficient (cost's less to operate). aside from that there isn't much difference, aside from not needing a double wall flue through the roof on a standard gas water heater.

You can save more money when purchasing a reliance water heater ,because it is less cash consuming and useful. Purchasing is cheaper them renting one.
At current gas prices they cost less to use and a gas heater gives you a much greater supply of hot water on demand.
No, an expansion tank is not required.
A lot less because the water is flowing if it is exiting and it depends on the water pipe size.
The install is difficult because insert hole is on driver's side, closest to firewall. The Toyota dealer charges $150 for part and install. Canadian Tire charges less than $100 (both less tax) Part is same. Install time charged at CT in Westbank, BC was 1/2 hour and part was $46. Routed cord myself. Heater is not inserted inside block but is clipped in place to heat the outside of the block.
