Why is your instant electric hot water system water temperature fluctuating
This is one of the more common questions we come across in the plumbing industry.
Particularly with short-stay apartments and rental property’s that have instant hot water systems installed and new tenant occupying the premises.
The answer to the question is more often than not a quick fix. Continuous/instant hot water systems require a minimum flow of water to engage the hot water system and ignite the burners.
Sometimes it can be that the hot tap is not completely turned on meaning the water flow is low. The operator then opens the cold water tap to reach the desired temperature which overpowers and restricts the hot water flow and the hot water system shuts down.
How to solve the water temperature issue
- Before using the shower, check your dishwasher or washing machine is turned off and not half way through a wash cycle.
- Completely open the hot tap in the shower.
- Wait until the hot water has reached the shower head.
- Slowly turn on the cold water until the desired temperature is set.
*For the best results, ensure nobody in the house uses the taps or toilet while you’re in the shower.
99% of the time the above steps will solve the problem in fluctuating water. If you’ve followed the steps above and find your water temperature is still fluctuating, it could be due to the following causes;
- The taps have ceased and cannot be opened completely which is limiting the water flow.
- A flow restrictor is installed in the showerhead or outlet limiting the water flow.
