How to Prepare for the Installation of a Small Electric Tankless Water Heater
A homeowner who needs a new water heater faces several factors when choosing the right unit. These include assessing the household’s hot-water consumption and available electrical capacity. It is also advisable to consult with a professional.
A small electric tankless water heater offers several benefits, including easy installation and low energy costs. It is ideal for homes with limited space for storage-type heaters. Its self-modulating technology adjusts power consumption according to demand.
Cost
The price of tankless water heaters varies depending on the size and type. For example, whole-home units that provide hot water for a large household tend to cost more than smaller point-of-use models. The installation cost also plays a role in the price. The plumber’s rate, supplies and any required permits are important factors in determining the final price of the project.
The energy type also impacts installation costs. Electric tankless models are typically less expensive than gas-powered ones. However, a gas-powered unit requires gas lines and ventilation systems, which can increase the cost of the overall project. In addition, a condensing unit is more efficient than a non-condensing model and can lower your utility bills over time.
Another factor that impacts the price of a tankless heater is its capacity. The more gallons per minute (GPM) it can produce, the higher the price. A plumber can help you determine the perfect capacity for your household by asking questions such as how many people live in the home and what are their typical hot water usage habits.

It’s always best to hire a professional, as improper installation can cause leaks or even release carbon monoxide.
Energy efficiency
While they may cost more upfront, tankless water heaters can pay for themselves with long-term energy savings. In fact, the EPA estimates that gas and electric tankless heaters can save homeowners $108 to $44 per year.
Unlike storage tanks, tankless models use less energy because they only heat water on demand. They also have a lower carbon footprint, since they don’t require fossil fuels to operate. Additionally, they’re more compact and don’t take up as much space in a home or business.

Tankless electric models are 90 percent smaller than their tank-style counterparts, which allows them to be installed at the point of use. This allows them to provide hot water within seconds. They can even be paired with a recirculation pump to further reduce waiting time.
The biggest consideration for tankless electric models is that they’ll need to be connected to a 240-volt electrical circuit. If your home’s electrical system is not able to accommodate this, you will need to upgrade it. However, it’s a small price to pay for the added efficiency and convenience.
Installation
The installation of a tankless electric water heater can be a complex project for homeowners. However, proper preparation can help the process run smoothly and save money in the long run.

You should also check the electrical connections to make sure they are in good condition. If they are loose, you should tighten them. Additionally, you should test the water flow rate to ensure that it is consistent and within the recommended range. You should also verify the temperature settings to ensure that they are correct.
If you notice that your tankless water heater is not working properly, it is a good idea to flush it. This is a simple process that requires turning off the power and gas supply to the unit.
