A lot of people are switching from traditional water tank heaters to electric tankless water heaters for good reasons. There are various benefits that these systems offer, including cheaper up-front costs, easy installation, and monthly electricity savings.
Your Home Situation
As noted above, there are various models on the market. Thus, you need to get the best for your home. If you want more education on different units, you can read reviews and guides to help you make the right decision.
Incoming Water Temperature
The systems can work best when they do not have to raise the temperature to over 30 F. You should note that even the most powerful units available cannot raise the temperature of water to 50 F notwithstanding the flow rate. If you want high temperatures, you should consider buying a tank or a gas powered unit. However, if you are planning to use the heater during the summer and spring months, this is the perfect system.
Flow Rate Needs
Different faucets and appliances need varying amounts of water. For instance, the bathroom sink uses far less hot water as compared to a dishwasher or washing machine. The systems are rated in terms of the flow rate. This is a vital factor to consider when determining the right unit to purchase. If you need a higher flow rate, then the unit to purchase will be more expensive and will use a lot of energy.
Size
Water heaters are available in a wide range of sizes. For instance, do you need a large tankless water heater or a small one? It is a good idea to measure the space available in your home before purchasing it. You should opt for a smaller unit if you want to preserve space or you need to install it in tight spaces such as under the bathroom or kitchen sink. Another vital factor to consider is capacity.
Brand
You should be aware of the company you are purchasing the device from. Look for tankless water heaters that have been rated to ensure quality. They should also come with a warranty.
