What Is A Tankless Water Heater

The tankless water heater is often installed in commercial buildings or homes that have limited storage space. It is wall-mounted and has a few pipes running into and out of it. Additionally, the purpose of the tankless water heater is to heat any water that flows through it and send that water back through your pipes for a hot shower or dishwasher, or washing machine.

The goal here is to lower your energy costs, provide an unlimited amount of hot water, and last longer than your storage-tank water heater. Tankless water heaters do not wear down as fast because they don’t have the stress and pressure build-up of water in the tank. They work less because they don’t store water, so their parts last longer.

Why The Leak

• Acid water – acidic water can eat away at your systems metal and plumbing. Pinholes can begin to form and allow water to leak out of the system. Do your best to reduce the acidic levels of your water so that your system can maintain its functionality.
• Hard water – hard water contains mineral deposits that can buildup in your system. This causes a system shut-down. You will notice an error code that messages you what the issue is. Make the repair and clean the pipes prior to attempting to restart the system. Failure to make the necessary repairs could cause long term damage to your system.
• Increased flow rates – the goal for a tankless water heater to work efficiently is to have a low flow rate of 5 GPM with a system pressure of 30 PSI. If you tankless water heater exceeds these numbers you will need to conduct maintenance on your shower-head and faucet aerators. High pressure can cause damage to the tankless heater and heat exchanger.
