Adding a tankless water heater to a tank system can be a great way to increase energy efficiency and hot water production. However, it’s best to consider all of the pros and cons before taking the plunge. Installing a tankless system can be quite complex, and it usually takes two to three days to install. It also carries a higher initial cost than a tanked system but can save you money in the long run due to its energy efficiency. You’ll need to make sure that your home’s wiring, plumbing, and fuel source are up to code as well. You also want to make sure that your home is compatible with a tankless system, as they require a specific flow rate to work properly. That being said, tankless water heaters can typically provide an uninterrupted hot water supply, safely and reliably, for many years with minimal maintenance.
install a tankless water heater to a tank
1.Turn off the power and the water to the tank by shutting off the circuit breaker and the main water supply.
2.Drain the old water tank by connecting a hose to the drain valve and draining the water out of the tank.
3.Remove the old water tank and any associated piping and fittings.
4.Install a new tankless water heater according to the manufacturer’s instructions.
5.Run the cold water supply to the tankless water heater and attach the appropriate fittings.
6.Install piping between the tankless water heater and the hot water lines in the home.
7.Connect the tankless water heater to the water outlets in the home.
8.Turn on the water supply at the main shutoff valve and check for any leaks.
9.Turn on the power to the water heater and test the heater to make sure it is working properly.
Adding a tankless water heater to a tank water heater system requires a few steps to properly install and configure the system for optimal operation.
1. Shut off the water supplies to the existing tank water heater.
2. Disconnect the existing tank water heater from the plumbing.
3. Install the new tankless water heater according to the manufacturer’s instructions.
4. Connect the tankless water heater to the plumbing using appropriately-sized pipe and fittings, ensuring that all connections are secured and all joints are properly sealed.
5. Turn the water supplies back on and test the tankless water heater to ensure it is operating correctly.
6. Adjust the settings on the tankless water heater per the manufacturer’s instructions.
7. Monitor the performance of the tankless water heater to be sure it is working as designed.
When adding a tankless water heater to a tank, it’s important to consider the water pressure and flow rate. A tankless water heater requires a higher water pressure than a tank-type water heater. If the existing water pressure is too low, then there won’t be enough pressure to properly heat the water. Additionally, a tankless water heater requires a higher flow rate than a tank-type water heater, so the hot water will be delivered more quickly. You may need to install a larger water line in order to accommodate the higher flow rate demanded by the tankless water heater. It’s important to also consider the energy efficiency of the tankless model you choose and make sure it meets local energy codes.
