What are full and partial warranties?
Full warranties
When users refer to a product “warranty”, they mean an all-charges-in type of warranty. These are full warranties.
Partial warranties
Partial warranties give users an impression of having a long warranty by guaranteeing only one part of the product. (e.g. 10 year warranty on heating element only)
Look out for:
Retailers that incorrectly market their partial warranties as full warranties.

Why is the tank warranty usually longer?
The Tank Warranty
The inner tank is the most important part of the water heater as once it leaks, the whole heater must be replaced. For this reason, tank warranties on the heater are usually longer.
Look out for:
10 year tank warranties – these are usually too good to be true. Often, these warranties come with extremely high labour costs which are equal to that of buying a new heater. (You may as well buy a new heater)
