Type of water heater

Usually, there are two main kinds of solar water heaters, namely: FPC and EPC. The FPC or flat heaters are more expensive than the other ones.

Size of the heater

When looking for a solar water heater, it is advisable to look for larger models. Although you might feel expensive, their performance and efficiency offset the price in the long run. 

Dual functionality

The conventional solar heaters only work in warm and sunny weather. However, if you are looking for a device that can perform well in all the conditions, settle for a dual functionality device.

If you are on a flexible budget, always choose a water heater from a well-known retailer with the maximum warranty possible. Otherwise, carefully look for the features and services the product provides and then make a decision. 


Do not forget to consider the ratings given to the product before you pay for it.
