The Wattage of the tank
For low-demand families, you should choose a Storage Water Heater with a capacity of 1500W - 2500W or a Tankless heater. If you consume a lot of electricity, you should pick a capacity of 3000W or higher or convert it to Solar.
Installation space
Because of the likelihood of heat loss when storing the container and the shower, this is especially necessary for the Storage or Solar. This will also affect the installation cost, so you should think carefully about it.
Warranty
Simple maintenance and installation are suitable for Tankless water heater. Dismantling and repairing is nearly tough to perform rapidly, especially with Solar water heater and storage water heater, and the cost will be exceedingly expensive if something goes wrong. As a result, the company's warranty will be required while making a purchase decision. To minimize mishaps, use reputed organizations with production expertise and knowledgeable technical employees while installation.
