To conserve water in your home, you should turn to a tankless water heater instead of an existing one. Tankless water heaters can save you money and reduce your carbon footprint while providing you with hot water more quickly than older models. They’re also safer: because they don’t store hot water in a water tank, they are less likely to overflow and spill out chemicals when not in use.
Instead of storing hot water for later use during peak times, a tankless heater heats up water as it’s needed for a given household. These appliances operate by transferring heat from the hot water source (for example, an electric or gas-powered shower) into the appliance itself. In some cases, you may have both a tankless and traditional hot-water heater in your home or business; the difference between the two is that with a tankless model, there is no storage tank or inner workings; this means it can be installed almost anywhere without needing further space or plumbing connections. The only requirement is to have an exterior wall where the device will be placed onto.
After nearly 17 hours of research, We think the high efficiency tankless water heater is Rinnai V75eN Non-Condensing Natural Gas Tankless Water Heater. Or you can check the Takagi T-H3S-DV-P Condensing High Efficiency Propane Indoor Tankless Water Heater as the other great option, even if the first option didn't meet all of your requirements.

Efficiency Rating
The difference between electricity and gas rates means that this rating doesn't give a good indication of the cost you could expect to pay for the unit. A gas heater with a lower efficiency rating will be more efficient than one that uses electricity. However, gas heaters are mucher than electric ones.
Because they don't have to run constantly to heat water, tankless heaters are significantlyer than storage tanks heaters. A tankless water heater can cut down on your energy bills by up to 40% depending on how much hot water you use. To determine the impact on your budget, it is better to calculate the annual operating cost for the hot water heater.

FAQs
How Often Should I Replace My Water Heater?
According to professionals, your water heater should be replaced every 10 years. A water heater cannot be guaranteed for this long. It is possible that your water heater will need to be replaced sooner than expected.
Gas Vs Electric Water Heaters: Which Is Right For You?
It's not cheap to install a water heater in your house. This is why it's important that you take some time thinking about how to charge your appliances. First, electric heaters offer the most sustainable option for the environment. If you choose one, it will be a better choice for your planet. Although electric water heaters work better, the price of electricity is higher than that of traditional gas options. You can still use your gas heater even if there is no power, so you have less to worry about during a crisis.
How Do You Drain A Water Heater?
First, drain the hot water heater by flushing it with water at full pressure. After connecting the drain line, open the drain valve and close it again. The valve will dislodge any sediment, allowing the system to drain faster.
Then, disconnect your water heater from either the electric or gas power supply and shut down the main water supply. Next, disconnect the drain hose from the quick flush and open the drain valve. Once you let air in the tank, water will not flow out. You will need to remove the hot water pipe from the top of the water heater, and then move the pipe to the side. You will see the tank begin to drain.
Can You Still Shower If Your Water Heater Is Leaking?
You can still take a hot shower even if your water heater is leaking. You can shower even if the leak becomes severe. It will just mean that you won't get hot water.
What Is A Water Heater?
A boiler is often confused with a water heater. What is the difference between a boiler and a water heater? A water heater heats water to be used for showering, cooking, cleaning, or other purposes. The water heater heats cold water coming from the water supply pipe. It then gives you hot water ready to use for washing your clothes or running a faucet. Water heaters use water that's suitable for cleaning and cooking (potable). A boiler, on the other hand is designed to heat your home and heat water from the taps.
How Do Water Heaters Work?
A tank-style water heater uses a dip tube that has an outlet in the bottom to heat the cold water. The tank's temperature is monitored by an internal thermostat which activates either a heating element, or a burner that warms water to the desired temperature.
Dual heating elements are used in electric water heaters to heat the water. The bottom heating element heats the coldest water faster, while the top one warms the water if it becomes too hot.
A pilot light, or electronic ignition system for gas water heaters ignites the gas that is flowing to a burner. Before shutting off, the burner heats water in the tank until it reaches a desired temperature. The exhaust is then vented outside.
Water heaters that are tankless don't keep water. They heat the water by using either electric or gas heating elements. The temperature of the hot water is a factor in how fast it flows, however most units are capable of providing hot water at a flow rate between 2 and 7 GPM.
What Are The Signs Your Hot Water Heater Is Going Out?
A failing water heater can be identified by a series of telltale symptoms, such as banging sounds inside the tank and a decrease in temperature.
Can Water Heaters Explode?
Electric and gas hot water heaters are susceptible to explosions. Explosions are rare, but can be caused by increased pressure in the heater, poor installation or maintenance, failure to set the temperature and relief valve (T & P), gas heaters, flammable liquids, or gas leaks.
How Long Does A Water Heater Last?
Although water heaters come with varying lifespan expectations, many can last for between 8-12 years. Some water heaters can last up to 20 years. Your water quality can make a difference in how long your heater will last. Over time, corrosion can occur from heavy minerals or sediment.
Depending on which model you select, the manufacturer may offer different warranty terms. The most common warranty period is usually between 6 and 9 years.
What Is The Best Compact Water Heater For Saving Space?
Mini-tank or tankless water heaters are compact and light, which makes them great for small homes that have less space.
