We at ReviewCounty try our best to provide the most valuable information to make your shopping experience easier. Check out the Top 3 of our choice.

Our compiled list of the Best Instant Water Heaters is here for our readers.

Our recommendations

We always recommend saving water and using lesser water for all purposes. More water is required if you take bath in shower or tub (about 25-30 lts), bathing using a bucket uses lesser water (about 15 lts). A 6, 10 or a 15 lts storage water heater is mostly sufficient for such use. In places that are cold or extremely cold during winters, a 15 lts water heater may be sufficient, whereas in places where the room water temperature is not too cold, a 10 or even a 6 lts water heater may suffice.

If water heater is to be used in kitchen and usage of water is less, a 6 or 10 lts storage water heater may be good enough. The intent should always be to heat optimum water to save electricity.  Smaller water heaters also have smaller energy losses and thus provide ideal water heating. Please note that there are few models of 6 or 10 ltrs storage water heaters are also rated at 3 kW (and not 2 kW). These are again not recommended from power system point of view.
