Do tankless water heaters have TPR valves?
Gas-fired tankless water heaters will usually require a pressure relief valve, while electric on-demand water heaters may not. The manufacturers typically only require a pressure relief valve, not the combination temperature and pressure relief valve that is necessary for tank-type water heaters.
What happens if you don’t descale your tankless water heater?
Why You Should Flush In standard tank models, failing to descale can pose a risk of explosion. Tankless water heaters won’t explode, but if you don’t flush out the sediment, you may force the unit’s heat exchanger to work harder than necessary.
What valve is required on a tankless heater?
Pressure-relief valves
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. The pressure relief valve is similar to an emergency stop valve.
Should I descale my tankless water heater?

Where is water heater relief valve?
Also known as the temperature/pressure relief valve, or the TPR valve, this valve is located near the top of the water heater. It usually features a lever you can lift up or down and has a discharge pipe that runs from the valve down to the water heater’s base.
What does a TPR valve do?
Temperature/pressure-relief or TPR valves are safety devices installed on water heating appliances, such as boilers and domestic water supply heaters. TPRs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels.
How do you remove calcium from a tankless water heater?
Treat with organic chemicals. — The most effective chemicals for combating calcium buildup are vinegar or lye. Once you flush your water heater, let the chemicals sit in the tank for a few hours, then flush it again before turning the heater back on for use. Keep it at the right temperature.

During a regular maintenance visit, a professional will descale, also called delime, your tankless water heater to make sure there’s no buildup around the heating elements. A professional should descale your water heater at least once a year.
What causes pressure relief valve to open?
When water is heated up inside of a water heater, thermal expansion causes the pressure inside of the tank to build up. If the temperature’s or pressure in your tank exceeds a certain level (often times 210 degrees and 150 psi), the relief valve opens up and allows some water to drain out of the tank.
What is a neutralizer on a tankless water heater?
9007607005. The 9007607005 Neutralizer assembly neutralizes the condensate (acidic water) that forms in the secondary heat exchanger of the water heater. It connects to the condensate drain port of the water heater by using connectors included with the neutralizer kit.
Do tankless water heaters really save energy?
A tankless water heater detects when you turn on the hot water tap and heats the water as it passes through the unit. When you turn off the tap, the tankless water heater also turns off. This helps save energy and money. Being tankless also means that these units are much smaller.
How hot is the water from a tankless water heater?
Depending on the brand and model, most tankless water heaters have a temperature setting that is adjustable between 100° to 140° (most tank water heaters are set around 120°). In order to make sure the water will be hot enough, it’s important that a tankless water heater is sized based on your climate and hot water needs.
How to flush a tankless water heater?
