How much power does each heater use?: Instant Water Heater vs Storage Water Heater Power Consumption

The power consumption of water heaters varies based on their type and model. Each heater uses different amounts of electricity due to its operational mechanism.


Instant water heaters, often preferred in the fast-paced city life of Singapore, offer on-demand hot water without needing to wait for a tank to heat up, thus potentially saving energy during short showers.


On the other hand, electric storage water heaters heat water in advance, maintaining it at the desired temperature, which might result in higher electricity usage if not managed properly.


In terms of safety, both electric instant heaters and electric storage water heaters must be installed properly to prevent issues such as water pressure irregularities and overheating concerns.


The false ceilings often found in Singapore bathrooms might impact heat retention and should be considered during installation.


For gas water heaters, there is an additional need to ensure proper ventilation to mitigate risks associated with gas use.


To compare electricity consumption: suppose an instant water heater uses 3kW and runs for 10 minutes per shower. In Singapore, where the average cost of electricity is about S$0.30 per kWh, the cost per shower would be approximately S$0.15.


Calculating for a storage water heater, which uses around 2kW and is on for 2 hours per day to ensure hot water is ready upon demand, the daily cost would be around S$1.20.


Therefore, selecting between instant and storage heaters involves comparing these operational dynamics, as well as considering factors like personal usage habits, pressure, and the needs of each bathroom.
