The layers get caked on and decrease the surface area available to heat up water. Avoid Cold Showers Scale build-up causes water to heat slower and decreases the maximum temperature of water coming out of your heater. Scale will keep adding layers until the system is no longer able to heat water going through your tankless water heater - meaning cold showers are in your future! Save Cash Tankless water heaters don't run efficiently with scale and require more energy (gas or electricity) to run. Extra energy costs add up month after month. You could hire a plumber to do the maintenance, or save even more - and do it yourself. Annual maintenance using a Kelaro Flush Kit keeps your system running efficiently and saves you energy. Even better, the kit can be reused year after year - just replace the cleaning agent.
