A tankless and a gas(with a normal tank) water heater both burn gas to heat the water, so they need vents to bring air into the space where they are located, and a venting system for the exhaust. Some considerations for tankless: 1) they require larger gas supply pipes; 2) they can be placed on most walls, but you still need room around them; and 3) they heat the water as it flows through the pipe, so you still have to deal with the cold water which is in the pipe. I mention the last one because many people think that they will immediatley obtain hot water. For your situation, placing the tankless heater on the third floor would require new gas pipes. Commonly gas pipes are 3/4" in a home, and a tankless unit may need 1" at a minimum. Having the water heater on the same level would provide you with hot water sooner. Placing the tankless unit where the hot water storage tank is may require less plumbing, so it could be an easier task. The water will take longer to heat, and you could be wasting energy of the heated water in the pipe. This can be partially resolved by insulating the hot water pipes. Insulating these pipes is a wise idea for efficiency in either location.
Gas tankless water heaters use high-powered burners that quickly heat water as it runs through a heat exchanger. It is 22 percent more energy efficient on average than the gas-fired storage-tank models.
It's called water heater. There isn't a reason to heat hot water
A hydronic heater works by using a boiler system to heat the water and then is pumped throughout the house in order to heat the specific area of a home.
Because it is a very good transmitter of heat.
A heat exchanger in a tankless water heater helps to efficiently transfer heat from the energy source to the water, allowing for quick and on-demand heating. This improves the heater's performance by providing a continuous supply of hot water while minimizing energy waste.

To ensure instant hot water with a tankless water heater, you can consider the following steps: Proper Sizing: Make sure the tankless water heater is appropriately sized for your household's hot water needs. Location: Install the tankless water heater close to the point of use to minimize the time it takes for hot water to reach the faucet or shower. Maintenance: Regularly maintain the tankless water heater by descaling it to prevent mineral buildup that can affect its performance. Insulation: Insulate hot water pipes to reduce heat loss and ensure hot water reaches the faucet quickly. Professional Installation: Have the tankless water heater installed by a qualified professional to ensure it functions efficiently. By following these steps, you can help ensure instant hot water in your home with a tankless water heater.
Not if it was disconnected properly
A tankless water heater heats water on demand, while a tank water heater stores and heats a large amount of water continuously. Tankless heaters are more efficient because they only heat water when needed, while tank heaters can waste energy keeping water hot. Tankless heaters are generally more efficient for providing hot water in a household.
In the long run a Rheem Tankless water heater will save you money in the long run by heating the water faster and you will have to run the water for a shorter amount of time for it to heat up.
A tankless water heater heats water on demand, while a regular water heater stores and heats water in a tank. Tankless heaters are more energy-efficient and space-saving compared to regular heaters, as they only heat water when needed and do not require a storage tank.
In a tankless water heater system, the pump functions to circulate water through the heating unit when hot water is needed. This helps to quickly heat the water as it flows through the system, providing a continuous supply of hot water on demand.
A tankless water heater heats water on demand, while an electric water heater stores and heats water in a tank. Tankless heaters are generally more efficient as they only heat water when needed, but electric heaters may be more cost-effective upfront. Ultimately, the choice depends on household hot water usage and energy efficiency priorities.

Tankless water heaters do not have a tank with a reserve of hot water that must be kept at temperature until there is a demand for it. Depending on the age of the water heater, this could result in a lot of wasted energy. Tankless water heaters heat the water as it is needed. These units are more expensive, but in the long run result in savings, both of money and energy.
Tankless water heaters are green because they only heat the water as it is needed. In a conventional water heater with a tank, there are 20 - 60 gallons of hot water that must be kept hot 24 hours a day, 7 days a week. Some of the heat in that water is constantly getting out of the tank, no matter how well it is insulated. That means that every so often, the heater must run to bring the water temperature back up. All that heat that leaks out is wasted. A tankless water heater doesn't use any energy when there is no water flowing.
