Going tankless when it comes to home water heaters is the best decision for millions of families in the country these days. When you think about all the benefits you gain for instance; a longer service life, ability to save energy bills by up to 50% and endless hot water in your house, why else would you not buy a tankless water heater?
Choosing the right tank for your home is however the more challenging bit for many people. But worry no more, because we are just about to go through the whole process of selecting the right water heater for your home in a few minutes.
Unlike a point of use water heater which you can easily install under the sink, a whole house tankless water heater will require the help of a technician to install properly. Sometimes you may also need to retrofit your home so as to accommodate this new device accordingly. Other than that, here are the main factors you should consider right before buying this new device.
Typical tankless water heaters are powered by natural gas, propane or electricity. If you decide to buy an electric water heater, ensure your power outlet’s voltage will be powerful enough to accommodate the amperage draw for your new device. You may also have your circuit breaker examined to ensure you home will be safe in case of any power accidents. Similarly for natural gas, ensure your home gas supply line can support the new heater. Don’t also forget to retrofit your home for venting purposes.
Determine Your Water Usage Needs
Different water heaters have different capabilities when it comes to providing hot water in your home. You therefore need to know how the total number of devices that will run hot water into your house. The showers and dishwashers for instance consume a lot of water, and hence will require a stronger device that will provide more hot water per minute.
You can calculate your water needs for yourself. Let’s say your kitchen faucet delivers 0.5 GPM, while your two showers deliver 2.5GPM each. In such a case therefore you need to go for a device with the ability to deliver hot water at a rate of more than 5GPM.
Required Temperature Rise
Quite frankly, tankless water heaters don’t always perform with the same efficiency at different temperature zones. In warmer climates, the heater can deliver hot water at a much faster rate than you would expect. In the colder Northern regions however, the room temperatures could affect the overall device’s performances.
Depending on the weather conditions of where you come from, choose a water heater that will deliver hot water at a fair rate irrespective of how cold it gets. In a place where the underground water temperatures are 500F, you may want a device that can raise temperatures by 600F and reach the average temperatures for a normal shower.
- Gas powered tankless water heaters are better off when it comes to raising water temperatures. Actually, the difference between a gas powered and an electric powered device when it comes to raising cold water temperatures is vast. Whereas the electric model can only raise 700F if the device is delivering water at a rate of 2 GPM, the gas counterpart can raise the same amount of temperatures for a device delivering hot water at a rate of 5GPM.
- The inlet flow rate can also affect the water heater’s performance – A fast inlet flow rate often affects the temperatures of water being delivered by the device.
- The Device’s control features – A great device is one you can easily control, especially the water temperatures.
- Presence of a warranty- Most trusted devices come with a two-five year warranty.
