Do tankless water heaters restrict flow?
Tankless water heaters work by restricting flow until the water reaches the preset temperature, so if the flow is too low from your tankless heater, you may increase it by lowering the temperature setting, says BEC Green. If that doesn’t work, it’s possible your heater is too small.
Do tankless water heaters lose pressure?
Deposits inside the heat exchanger can cause the outlets from the tankless system to become clogged. If you notice low water pressure coming from your hot water faucets, these clogs might be the reason. The most common cause of these deposits is hard water.

Why has my hot water pressure dropped?
The cause of your low hot water pressure could be debris and sediment in showerheads and taps, water leaks, blocked filters, a faulty tempering valve or something else.
What causes too much pressure in tankless water heater?
There’s a safety valve in every water heater, called the Temperature and Pressure Relief Valve, or a T&P relief valve. In short, when the temperature or pressure of the water heater gets too high, the valve opens, and releases water that’s causing the increase in pressure.
How do I know if my tankless water heater is leaking?
If your tankless water heater is functioning correctly, it should not be dripping. The only exception is when there is a drip at the relief valve due to mounting pressure within your water heater. Any other drip or leak will be a result of one of the above reasons highlighted earlier.
Do tankless water heaters need a pressure relief valve?
Pressure-relief valves are an essential component of tankless water heaters. The valves allow you to manually release air from the heating chamber when filling the chamber with water for the first time, or during periodic maintenance.
When should I replace my tankless water heater?
How Long Do Tankless Water Heaters Last? Gas-burning tankless water heaters should operate for 20 years or more, two or three times longer than tank-type heaters. Tankless electric units have shorter life spans, on the order of 7 to 10 years.
Why would a tankless water heater stop working?
The Air Supply or Exhaust Is Blocked
At times, your exhaust or air supply might get blocked, which can cause your tankless water heater to stop heating. Many water heaters will automatically shut off as a way to protect the appliance and help prevent other safety hazards that could result.
How many years does a tankless water heater last?
20 years
Most tankless water heaters will last for up to 20 years or more, which is a long lifespan in comparison to tank water heaters, which last around 10–15 years.
