The electrical connections for old homes were designed in a centralized manner. The main electrical supply would be the hub of the house. This would be that spot where maximum distribution took place. Today, people have recognized the disadvantages of such an approach.
For starters, even the slightest excess consumption in a single room puts the entire house at risk. This has led to installation of circuit breakers and divisions all over the house. For example, a house with two floors can be divided into two different houses of one floor each.
Although the power meter can remain the same, the supply can be rooted in such a manner that there are two electrical mains for each floor. In such a scenario, it becomes easy to isolate the problematic area. Further, the division can be done on the basis of rooms. Each and every room can have a specific circuit breaker. Once this circuit breaker falls, the supply to that room will come to an end.
The breakers can be determined on the basis of the total number of appliances that may be installed in the room. For example, a kitchen is obviously going to require more power supply because there would be numerous electrical items fitted in it.
On the other hand, a bathroom or a study room would not have numerous electrical appliances unless you have installed air conditioners in each and every room. This means that the resistance to excess power can be higher in case of the kitchen and lower in case of the other rooms.
Despite this, you should pay special attention to the power factor when installing water heater under the sink or any other place in the kitchen. Did you intend to do so from the very beginning? If yes, then you should not have any problem in installing the device.
However, if you never anticipated the possibility of installation of heater in the kitchen, you may have to make changes to the electrical setup. The last thing you want is for your supply to trip on a regular basis just because the heater is drawing excess power.
You may end up in a scenario where you cannot use multiple devices in the kitchen at the same point of time. Even if you intend to use the heater on a very irregular basis, you cannot afford such a setup. The smartest option is to have an electrical expert take a look at the entire set up before finalizing the deal and proceeding further.
