Which Factors Should You Consider Before Buying a Rheem Tankless Water Heater?
The majority of homeowners in the US, Canada, and Singapore want to install Rheem water heaters, but they are unaware of what factors to take into consideration when selecting a storage water heater for their homes.
Rheem water heater models are widely accessible in various countries, and what sets each model apart from the others is its size, appearance, or cost.
The following considerations should be taken into account when purchasing or installing a Rheem water heater for hard water.
Storage Type
You should think about the water heater’s storage kind while purchasing one. The majority of Rheem storage water heaters heat water in a tank that is typically filled with water.
To get hot water to come out of the showerhead or the tap while utilizing a Rheem storage water heater, you will need to turn the valves on your faucet. This occurs when cold water enters the storage water heater’s tank and efficiently heats the water.
On the latter, rapid water heaters are energy-efficient but lack storage tanks. The water in an immediate water heater is heated by coils to the desired temperature.
Storage Capacity
The capacity, or quantity of hot water that the storage water heaters can hold, is typically mentioned. The smallest size typically has a capacity of three liters.
On the other hand, the larger storage water heaters can be able to hold twenty-five liters or more and are typically utilized in large residences and commercial buildings. You can go for 75-gallon water heaters for large homes.
The capacity of a Rheem storage water heater will be determined by how much hot water it produces each second, typically measured in liters per second or gallons per minute.
Energy Efficiency
The main driver of demand for tankless water heaters is rising customer concerns about energy sustainability. In general, storage water heaters use a lot of electricity. Due to the fact that they adhere to the energy efficiency standards Singapore is pushing.
“The market of tankless water heaters was estimated at $3.26 billion globally in 2021, and from 2022 to 2030, it is anticipated to grow at a CAGR of 8.7%.” Source
Rheem water heaters have top models that are energy-efficient. With an instant water heater, on the other hand, you can save more energy at least 30% more because they only produce heat when it is actually needed.
So, Rheem storage water heaters use more energy since they can hold more water than other types of water heaters.
Household Size
The space you have in your home or bathroom for the placement of the Rheem storage water heater installation.
It must be taken into consideration during water heater installation because it may involve electrical configuration and could impair the water heater’s overall performance as well as lead to a power trip.
Therefore, the size of storage water heaters varies according to the heater’s capacity, installing low-capacity storage water heaters will take up less room.
Safety Precautions
You should think about your own safety as a customer. Your installed water heater may occasionally produce steam, and the added pressure may harm it.
There is a safety valve on top-of-the-line water heaters like Rheem’s that makes sure there is no excessive pressure inside the heater.
Finally, the recent Rheem water heater models include a thermostat mechanism that shuts off the electric supply once the water reaches the maximum temperature setting in order to prevent overheating that can result in water heater problems.
Installation and Maintenance Cost of Rheem Tankless Water Heater
For Rheem to honor the warranty, professional installation is necessary. The guarantee will be nullified if the product is installed improperly.
Rheem tankless water heaters range in price from $350 to $1,100 for electric units with a 5-year warranty to $630 to $2,000 for gas systems with a 12-year warranty.
One of the biggest producers of water heaters in the US is Rheem, and their tankless gas models adhere to tight Low-NOx emission regulations.
Some Drawbacks of Rheem Tankless Water Heaters
Despite being touted as one of the greatest water heaters, there are several drawbacks and risks of the Rheem tankless water heaters that you should be aware of. The key ones are listed below.
High Installation & Maintenance Cost
When compared to a traditional water heater, the upfront cost of installing a Rheem tankless water heater is very expensive. In fact, the least expensive model is about twice as expensive as conventional devices.
Additionally, the cost of labor and other installation expenses is very high. For instance, if you choose a gas hot water heater, you will have to pay a lot of money to reroute your gas lines.
Inconsistent Temperature
If you are only using one machine, not multiple, a Rheem tankless water heater will only give constant hot water.
Users have cited inconsistent water heating as one of the system’s shortcomings in the majority of tankless water heater evaluations. To reduce heating irregularities, you might install many tankless water heaters.
Long-Term Maintenance
The maintenance of a Rheem tankless water heater is similar to that of traditional tanks. To get rid of the calcium, silt, minerals, and other things in the system, you must flush it at least once a year.
The system also has fans and filtration, which need routine maintenance to work effectively. Due to the system’s intricacy, experts advise engaging specialists to carry out the maintenance.
