Installation instructions come with tankless water heater, but would recommend someone experienced enough to install.
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.
A tankless water heater uses less electricity compared to a traditional water heater because it only heats water when needed, whereas a traditional water heater continuously heats and stores water.
A small tank water heater is more energy-efficient, takes up less space, and heats water quickly compared to a traditional water heater.
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.
Tankless hot water heaters powered by propane offer several benefits, including energy efficiency, cost savings on utility bills, endless hot water supply, and a longer lifespan compared to traditional water heaters. Additionally, they take up less space and produce fewer greenhouse gas emissions, making them a more environmentally friendly option.
Tank electric water heaters have the advantage of being more affordable upfront, easier to install, and have a simple design that requires less maintenance compared to other types of water heaters.
Propane heaters cost less to run per hour.
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.
