Canadian manufacturer Giant produces several types of electric water heaters for residential and commercial water and space heating applications. Giant electric water heaters are designed with the storage water tank and depending on the capacity they can operate in homes with the lower hot water demand such as the point-of-use type, and as models for the whole-house water heating.
Two groups of the whole-house electric water heaters can be differentiated; conventional with two, upper and lower heating elements and exclusively made by the Giant manufacturer – models with three heating elements. All the models are floor standing units that do not require venting – only electricity and water, which makes them easy to install and maintain.
Point-of-use water heaters have a small size and therefore capacity, and are meant for the distant sinks, or single fixtures in the offices, garages, cottages, apartments, and places where the small amount of hot water is needed. These are built as the hot water tanks with the capacities ranging from the smallest of 2 gallons to the largest model with 22 gallons. As its big brother- tall tank-type water heaters, point-of-use units are also equipped with the high-quality protective anode rod while having only one heating element that can operate with the power from 1 kW to 3 kW depending on the voltage (except the 2-gal unit – 103ETE).
Giant electric water heaters for the whole-house water heating can be found as the standard type with the capacities from 30 to 60 gallons, also Cascade and Super Cascade models - both groups with the 40 and 60 gallons. The best choice for the homeowners are the Super Cascade models as they are equipped with the stronger anode rod (made of magnesium) and double layers of blue cobalt glass – both features protecting the metal components from corrosion.
Other features specific for this series include the low watt heating elements, the high-quality brass drain valve (others have plastic valves), bottom cold water access for an increased hot water delivery and the warranty of 10 years for the metal storage tank and 5 years on other elements.
Giant electric water heaters are also designed with the EcoPeak technology; a technology that utilizes not two, but three heating elements; the top element with the 3,800 Watts, a middle element with the 3,000 Watts and lower heating element with the 800 Watts – less powerful than two-element setup heaters but overall more durable and reliable. The lower element works almost all the time, while the other two when it is needed, resulting in fewer Watts required during the peak hours, water is heated evenly throughout the tank, while supplying hot water in sufficient amount, as the traditional models. The EcoPeak technology is found on the Cascade and Super Cascade 60-gal models only.
While the standard type can operate with the factory installed wattages from 120 V to 240 V, models with the EcoPeak technology, operate on 208 V and 240 V.
The common features found on all models are the GreenFoam, 2”- thick Eco-friendly foam insulation that reduces the standby heat loss while keeping the heat longer inside the water tank, and the adjustable thermostats with the safety cut-off for the temperature control and protection against overheating.
According to the upper review of the Giant electric water heaters, it can be said that the best models are coming from the Super Cascade group that utilizes the EcoPeak technology due to the high performance, quality features, long lasting elements and great warranty of 10 years.
