Here are the key considerations to have before choosing between the two:
Temperature Consistency: If you leave a fast-paced lifestyle and require consistent hot shower for your daily activities, then STORAGE water heater should give you the consistency you need.
Pressure and flow: This varies for every person. Some people want low pressure for showering, and the instant water heater is the best option. For those who require higher water pressure, storage water can deliver the job.
Space: Most Singaporean homes go for instant or tankless water heater because they do not only look good aesthetically; they also require way less space for installation. The storage water heater is more appropriate for a large household with heavy usage for hot water.
