Electric water heaters are divided into single-tank and double-tank models. What are the differences between them? What are the advantages of double-tank water heaters?

1. Single-tank water heaters heat up slower and have a lower hot water output rate than double-tank water heaters of the same capacity. Their heat retention is also relatively poor, resulting in higher electricity consumption. In terms of space, single-tank water heaters are bulkier, with greater thickness and depth, while double-tank water heaters occupy less space and have a thinner body.

2. Double-tank fast-heating water heaters feature a novel ultra-thin design and a rational structure, offering rapid heating and variable capacity functions, providing users with a more energy-efficient, convenient, and flexible usage method.

3. The dual-tank instant-heating electric water heater is a new type of storage-type electric water heater with a new structure, new functions, and a new appearance. It adopts a novel appearance and reasonable structure with a dual-tank ultra-thin design, featuring rapid heating and variable capacity functions, and has a higher hot water output rate. Its different heating methods can obtain different capacities of hot water and heating speeds. The Angel dual-tank instant-heating electric water heater can achieve the effect of variable capacity and rapid heating, and can reduce residual water and heat more than the single-tank instant heating solution, providing users with a more energy-saving, convenient, and flexible way of use.

4. The dual-tank rapid-heating electric water heater is a new type of storage-type electric water heater with a novel structure, new functions, and a new appearance. It adopts a novel ultra-thin dual-tank design and a reasonable structure, featuring rapid heating and variable capacity functions, resulting in a higher hot water output rate. Its different heating methods can produce different capacities of hot water and heating speeds. The Angel dual-tank rapid-heating electric water heater achieves variable capacity and rapid heating effects, and compared to single-tank rapid-heating solutions, it reduces residual water and heat, providing users with a more energy-saving, convenient, and flexible usage method.

5. High reliability: The dual-tank electric water heater has two heating elements. If one heating element fails, the other can still heat, and the water heater can still be used. A single-tank electric water heater has only one heating element; if it fails, the water heater cannot be used.

6. Rapid heating: Compared to a single-tank cylindrical electric water heater of the same capacity, the dual-tank electric water heater has a smaller storage capacity, higher heating power, and shorter preheating time.

7. Small footprint: Dual-tank electric water heaters are generally flat and round in shape, taking up less space compared to single-tank cylindrical electric water heaters of the same capacity.
