Electric Water Heater with Variable Hot Water Capacity

[Category : - ELECTRONICS- Construction Processes & Equipment- ELECTRICITY & LIGHTING]
[Viewed 110 times]

This patent makes any new electric water heater much more efficient according to the new seasonal energy efficiency ratios in place in western countries.

It simply manually or automatically adjusts the capacity of the hot water within the water tank of an electric water heater, so for instance reducing the capacity of hot water if there are only 2 occupants in the house and increasing it if there are 4 occupants. The consequence is that only the hot water that is really needed is heated according to user and automatic settings, saving an enormous amount of energy annually and improving the seasonal energy efficiency ratios.


Description

This is a generic patent that benefits all current electric water heaters in the market today. By implementing this invention, any new electric water heater will improve its seasonal energy efficiency ratios.
The patent relates to a system that manually or automatically adjusts the hot water capacity of the electric water heater to the real need, eliminating energy waist and optimizing energy consumption. In a house where there are 2 occupants habitually, the need for hot water can be 100L, but what happen if, for example, the children turn up for Christmas and the occupation becomes temporarily 5 occupants? The 100L electric water heater capacity becomes short to fulfill the new hot water demand... Alternatively, a house that can fit 5 occupants will have a water heater of +200L to meet the demand of all 5 occupants. The water heater will always be full and the energy it will require is to heat the full capacity. But what if the real occupancy of the house is 2? They don’t need so much hot water heated all the time, so there is a energy waist and a lack of optimization in energy consumption, redounding in a further increase of the energy bill…
The invention of the electric water heater of variable capacity, (Spanish Patent granted and PCT Patent Pending ) allows the user or automatically to increment / decrement the capacity of hot water within the tank of the water heater with a simple, cheap to build system, that can be implemented in different ways all covered by the patent.

The great advantage of the invention is that, unlike all electric water heaters in the market today that are always full irrespective of the water being consumed, the patent permits the user or automatically to increase / decrease the hot water capacity within the water tank so when there are fewer people in the house / industry / hotel … the energy needed to heat the water will be much less, because there will be less capacity of water to be heated; and when the need of hot water is more the capacity will be more, taking more energy. The result is a great optimization of the energy consumption throughout the year delivering a great seasonal energy efficiency ratio, which is the new main measure to evaluate the efficiency of an appliance.
The patent is generic invoking several ways to increase / decrease the capacity of the water tank. This system can be sold to any electric water heaters manufacturers so they can implement it in their new models to start selling new electric water heaters that are better compliant with the new energy efficiency regulations worldwide.



Financial information

This patent can benefit all tank based electric water heaters in the world. From now on all can implement this invention so their seasonal energy efficiency ratio will improve drastically contributing to much savings for the user and a more efficient and optimal energy consumption worldwide.
