Using Hard Water? Here Are Three Signs Your Tankless Hot Water System Requires Repairs
Tankless hot water systems are a significant improvement from the traditional tanked options. They bring convenience by allowing you to access hot water when you need it. These systems also save energy as they don't have to keep reheating stored water. However, despite their numerous advantages, they can't hold up against hard water. If you're using hard water in your home, the minerals may slowly start to degrade your heater.
You should be on the lookout for hard water-related problems that can cause your heater to malfunction. Here are three signs that indicate you need to repair the heater before it fails.
Inadequate Hot Water
Tankless hot water systems should produce a constant flow of hot water at all times unless there's a power outage. If your heater is suddenly not heating the water properly even after setting the thermostat, it could be on the road to failure. In homes with hard water, the minerals in the water buildup around the element over time. They create a physical barrier that prevents the element from heating the water properly.
For you to get water at the right temperatures, you have to clean the hot water system to get rid of the accumulated minerals. This is done in a process known as descaling. If the heater is severely damaged, it should be replaced. In the future, you should consider softening your water to prevent mineral buildup in the heating system.
Rust-Coloured Water and Musty Smells
Excessive mineral buildup in your tankless heating system will lead to corrosion of metallic parts. They rust sheds into the water, and this causes your hot water to have a brown or rust- like colour. You may also notice a metallic smell in the water. Additionally, corrosion wears metal parts and can cause leaks in the system. The leaks and high temperatures around the heater encourage the growth of mould, which gives off a musty odour.
Rusted components in your heating system may require immediate replacement. Ask your plumber to inspect the system for leaks as well. They will not only lead to energy inefficiencies but will also cause mould and air quality issues in your home.
Unusually Low Water Pressure
There are times when the water pressure in your home is low due to reduced water supply. However, if the pressure issues are only isolated to the hot water faucets and shower, your heater may be on the brink of failure. Again, the accumulation of minerals in your hot water pipes can cause blockage and reduce water flow to the faucets. Check the pressure of the cold water in your home. If it's high, your heating system requires immediate repairs.
Call a plumber for hot water repairs if you notice any of these signs. Also, if you don't intend to buy a water softener, schedule for regular descaling to protect your water heater from the devastating effects of hard water.
