With the fluctuating temperatures in Canada, a water heater is a must in every household. While many people opt for a tank water heater, tankless water heater is also pretty common in Edmonton. Like any other home appliance, an old tankless water heater also starts showing some issues over a period of time. Here are some common problems with old tankless water heater listed by Edmonton hot water heater installation specialist.
Accumulation of Sediments
This problem is majorly faced in areas which get hard water. Edmonton receives moderately hard water. As a result, there’s accumulation of sediments around the heating coil when the water is heated. A major build up over time could lead to breaking down of the heater.
Corrosion is comparatively less in a tankless water heater as compared to a tank water heater. Nevertheless, it can be a problem in old tankless water heaters. Corrosion in the water heater could drip out the condensation in the burner, thereby blocking the gas supply. Such a situation could shut down the system.
A tank water heater has low maintenance cost due to its simple mechanism. The intricate details of a tankless water heater make it expensive to maintain. It has minute parts which can cost more compared to a tank water heater. Also, long-term usage leads to increase in the wear and tear and recurring maintenance.
Cold Water Sandwich Effect
The cold water sandwich effect is an occurrence in which the water released from the water heater is hot for a few minutes, and then there is a gust of cold water. The water then again goes back to being warm, though it may not reach the optimum or desired temperature. The residual hot water, left in the pipes, is a major reason for its occurrence.
Since the process of heating water in a tankless water heater is a quick one, there is a lot of heat in the system. Proper venting is a necessity for tankless water heaters. Over a period of time, the vents tend to get clogged resulting in a blockage. This leads to the heater shutting down altogether.
Water heaters have a long lifespan. Malfunctioning of certain features over a period of time is bound to happen. These issues can be avoided by proper and timely repair of your tankless water heater. A good Edmonton hot water heater installation professional would provide you with tips to maintain the water heater at the time of installation itself.
