In a final step, the one or more fastener members [202] are guided through the one or more cut-out portions [218], by means of the one or more depressed guide slots [110]. More particularly, the first and second fastener members [202a, 202b] are guided through the first and second cut-out portions [218a, 218b], by means of the

first and second depressed guide slots [110a, 110b]. Notably, this step facilitates mounting and supporting of the electrical appliance [100] on the first and second fastener members [202a, 202b].
THERMAL EFFICIENCY TEST RESULTS
The standing loss test data (thermal efficiency) for the water heater [100] is mentioned below. Table 1 provides a tabulation of the test results for standing loss in the water heater [100] of 15L capacity. Table 1 is to be referred to in conjunction with the description provided hereunder, in order to better understand the concepts of the present disclosure.

Star rating 5 star
Water Heater Capacity 15L
Average Cut-In Temperature (θA) 67.94°C
Average Cut-Off Temperature (θE) 72.26°C
Average of Cut-in & Cut-off Temperatures
(θM) 70.10°C
Total energy consumed (E1) 704 J
Total time (t1) 52.10676568 minutes
E = (E1*24)/ t1 324.2573163 J
Average Ambient Temperature (θamb) 26.75294118°C
Net Heat Loss (Qpr) = (45/θM-θamb))*E 336.6080102 J
Table 1: Standing loss test data for water heater
Table 1 represents the standing loss test data for the water heater [100] having a capacity of 15L and a safety rating of 5 star. It is noted that for a water heater to be compliant with the safety rating of 5 star, the net heat loss shall be less than or equal to 381 J.

Generally, the conventional water heaters with the same capacity (i.e., 15L) and same safety rating (i.e., 5 star) results in a net heat loss in the water heater of about Qex = 381 J, which falls on the border of the prescribed 5-star rating norms. Whereas, as represented in Table 1, the water heater [100] of the present invention results in a net heat loss in the water heater [100] of Qpr = 336.6 J, i.e., a 10% reduction in the net heat loss from the conventional water heaters.
Thus, the mounting arrangement [200] for the water heater [100], as disclosed in the present invention, proves to provide a better thermal efficiency as compared to the conventional mounting arrangements.
Advantageously, the mounting arrangement [200] facilitates low heat loss at the depressed region [108] of the electrical appliance [100]. The mounting arrangement [200] also provides for a fail-safe installation in view of the blind connection, by engagement of the one or more fastener members [202] with the one or more cut¬out portions [218] of the mounting bracket member [206]. Furthermore, the mounting bracket member [206] has a robust and receptive design for active engagement with the one or more fastener members [202].
Additionally, the spacer member [204] is made up of a plastic material. The insert moulding of the insert moulded nut [210] within the spacer member [204] facilitates thermal insulation and disconnects heat flow from the bracket portion [106] of the tank member [102] to the surrounding environment, through the one or more fastener members [202] and the mounting bracket member [206] of the mounting arrangement [200], thereby improving thermal efficiency of the electrical appliance [100].
Further, the mounting bracket member [206] and the one or more fastener members [202] make no metal-to-metal contact with the bracket portion [106] of the tank member [102], thus eliminating loss of heat to the surrounding environment. This, in turn, enhances the thermal efficiency of the electrical appliance [100].

While the preferred embodiments of the present invention have been described hereinabove, it should be understood that various changes, adaptations, and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims. It will be obvious to a person skilled in the art that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive.
