On-demand water heater now protected
The high efficiency on-demand water heaters are great. Unlike a traditional water heater that holds 40 or 60 gallons of water and keeps reheating it over and over, the on-demand system only does the job when needed. Open any hot water tap in the house and, when the water starts to flow, the flame ignites and the water is heated as it is delivered. Once the tap is closed, the system shuts down.
These water heaters work great provided that the water going through them has no iron and very little, if any, hardness. Having either element in the water will cause problems that reduce the efficiency of the heater and lead to maintenance issues. The best scenario is to condition the water with a softener to ensure the water heater operates properly.
This family in Lucan (south of Exeter) wanted a water softener that would use a minimal amount of salt and not require ongoing maintenance. The model we installed keeps track of the household water use for the past 28 days (exactly 4 weeks) and adjusts its cleaning cycle as needed based on the past average for the upcoming day.
