Just like changing the oil in your car, the tankless water heater also requires regular maintenance for its best performance. Flushing tankless water heater eliminates the minerals and sediments that can affect the performance of your water heater. These may include of lime and calcium.
On tanked water heaters sediment gathers in the tank at the base. With tankless water heaters, sediment will gather in the heat exchanger and interior piping, slowly narrowing the openings which restricts the amount of water flow. Due to this reason, the heater works harder and demands more energy and time to heat the same amount of water.
A lot of manufacturers suggest flushing the tankless water heater at least once or twice a year. Some plumbing companies send homeowners a reminder as the yearly flushing of water heater is essential.
As per the flushing requirements, these actually depend on the quality of the water and the place you reside. In Seattle, for example, the need for flushing is seldom due to the fact that it has the cleanest water all throughout the region. On the other hand, most tankless water heaters in California must be flushed at least once or even twice a year. But, it is still best to stick to the recommendation of your professional plumber.
Having a service valve kit allows for easy maintenance of a tankless water heater. Each kit should include (2) valves – one for hot side and one for cold, both color coded, with a full flow side drain valve, and a pressure relief valve (a required component for water heater installation). Bypass service kits are compatible with all tankless brands, including Navien, Takagi, Rinnai, Paloma, Bosch, Noritz and many others. Meeting California lead-free requirements the tankless water heater kits are Lead-free brass construction. Without these bypass kits it is impossible to completely flush and service the tankless unit correctly.
Professional plumbers will connect a hose to the water tank, drain the water and then flush the inside of the tankless water heater usually with a biodegradable solution. This has to be done with some type of pump and should be cleansed multiple times, taking up to an hour plus. This eliminates the sediments inside the heat exchanger and gives clean hot water with faster flow rates. The impressive thing about hiring a professional plumber is that they also clean and assess the filters, flow sensors, temperature rise, the ventilation and all other essential parts.
There are some consequences of not flushing the tankless water heater. Apart from decreased energy efficiency, the sediments that gather in the water heater result in even more serious issues. Once this sediment gets into your unit and pipes, you may later be shocked as they come out of your faucet. The moths and dirt daubers can also create the nests in the piping. And thus, you’ll have to face even more serious issues.
