Installation instructions come with tankless water heater, but would recommend someone experienced enough to install.
Propane heaters cost less to run per hour.
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.
Propane heaters cost less to run per hour.
My guess is that the hot water heater is installed downstream from a pressure reducer to limit the maximum water pressure that the water heater is exposed to.
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.
A propane-powered generator is a generator that is powered by propane instead of being battery powered or running on electricity. A generator is a device that generates electricity to power a home and/or heating and/or water system during a power outage. Propane-powered generators start easier and fast and need less time to warm up.
