Nowadays, water heaters are installed in the bathrooms of nearly every household. The choice of water‑heater type depends on personal preference. Available options include storage‑type electric water heaters, rapid‑heating electric water heaters, instant‑electric water heaters, gas water heaters, solar water heaters and the new‑generation air‑source water heaters. Each type has its own strengths, and users may select according to household demands. Today we will focus on rapid‑heating electric water heaters. If you are interested, we will cover other types of water heaters in subsequent articles for your reference.
Literally, a rapid‑heating electric water heater heats water quickly. It sits between storage‑type and instant‑electric water heaters, or can be regarded as a combination of both. Adopting rapid‑heating engine technology, it delivers fast hot‑water output with low‑power heating. As a new‑generation electric water heater, what are its advantages and disadvantages?
- 1.Fast hot‑water output, no long waiting: Unlike storage‑type models that require long pre‑heating, it only takes 3‑5 minutes of pre‑heating to obtain hot water at a comfortable temperature, satisfying the demands of modern fast‑paced lifestyles.
- 2.Energy‑saving and power‑saving: Turn it on when needed and switch it off after use. It supplies hot‑water on demand and avoids energy waste from leftover hot water, saving 30%‑50% electricity. Classified as a national energy‑saving product, it is of great significance amid today’s water and power resource constraints.
- 3.Safe and eco‑friendly: Safety has always been a major concern for electric water‑heater users. To fully guarantee user safety, great efforts have been made in product research and development. Multiple safety features such as water‑electric isolation technology, leakage‑protection device, high‑pressure relief, electronic control, temperature display and multi‑level power settings are adopted to achieve maximum safety performance.
Having covered so many merits, does the rapid‑heating electric water heater have no drawbacks? Certainly it has some shortcomings, which are introduced below.
- 1.Relatively high power rating: Fast hot‑water output requires relatively high power. The power of rapid‑heating electric water heaters generally ranges from 5000 W to 6000 W. If you plan to use this product, new wiring is required during bathroom renovation or retrofitting. For safety purposes, 4‑square‑millimeter wires are required. For instant‑electric water heaters, wires of no less than 6 square‑millimeters are needed. Such requirements should be calculated at the early‑stage of renovation design.
- 2.Strict installation requirements: The inlet water pressure shall not be excessively high. A separate 32 A air‑circuit breaker must be installed at the household electricity meter with dedicated wiring. Taking other household appliances into account, the main circuit breaker shall be at least 80 A. This has long been a bottleneck for rapid‑heating electric water heaters. Nevertheless, such constraints are gradually diminishing with the improvement of living standards.
That is all for today’s introduction to rapid‑heating electric water heaters. For genuine hands‑on experience, you need to purchase, install and operate the product yourself. Hope this article is helpful to you!
