best outdoor tankless water heater
The best outdoor tankless water heater is a type of water heating system that does not have a storage tank. Instead, it heats water on demand as it flows through the unit. The heater is installed outside of the home and is connected to the indoor plumbing system. These types of water heaters are more energy efficient than traditional tank-style water heaters as they only heat the water as it is needed, rather than constantly maintaining the temperature of a full tank of water. Outdoor tankless water heaters are also typically more compact and take up less space than indoor tank-style water heaters.

Factors to consider When purchasing the Best outdoor Tankless Water Heater
Size:
Tankless water heaters come in a range of sizes, and it’s important to choose one that is appropriately sized for your household. A unit that is too small will not be able to keep up with demand, while a unit that is too large will be less efficient and more expensive to operate.
Fuel type:
Tankless water heaters can be powered by electricity, natural gas, or propane. Each fuel type has its own pros and cons, so you should consider which one is most suitable for your home and budget.
Natural gas: Tankless water heaters that use natural gas are generally the most cost-effective option, as natural gas is typically less expensive than electricity. They are also relatively efficient, with some models having energy efficiency ratings as high as 98%.
Propane: Tankless water heaters that run on propane are a good choice for areas where natural gas is not available. They are generally more expensive to operate than natural gas models, but still more cost-effective than electric tankless water heaters.
Electric: Tankless water heaters that use electricity are the most expensive to operate, but they have the advantage of being able to be used in any location since they do not require a gas line. They are also relatively efficient, with some models having energy efficiency ratings of up to 99%.
Efficiency:
Look for the best outdoor tankless water heater that has a high energy factor (EF) rating, as this will indicate how efficiently the unit converts fuel into heat.
Warranty: Make sure to choose a tankless water heater that comes with a good warranty, as this will provide you with protection in case anything goes wrong with the unit.
Price:
The best outdoor tankless water heater can vary significantly in price, so it’s important to set a budget and look for a unit that fits within it.
Flow rate:
The flow rate of the best outdoor tankless water heater refers to the amount of water that the heater can heat and deliver to a plumbing fixture, such as a showerhead or faucet, in a given amount of time. It is usually measured in gallons per minute (GPM).
For example, if a water heater has a flow rate of 4 GPM and you are using a showerhead that has a flow rate of 2.5 GPM, the water heater will be able to fully heat the water for the shower. However, if you were using a showerhead with a flow rate of 5 GPM, the water heater would not be able to fully heat all the water, and you would experience a decrease in the temperature of the water as you shower.
The flow rate of a water heater can be affected by a variety of factors, such as the size of the heater, the type of fuel it uses, and the efficiency of the heating element. In general, larger water heaters and those with more efficient heating elements will have higher flow rates.
