Double energy source water heater system with quick heat supply function

Abstract

The invention discloses a double energy source water heater system with a quick heat supply function. According to the system, an instantaneous hot water heating device is connected in series between a hot water port of a household water device and a water outlet of hot water of a gas water heater (or a gas wall-hanging stove). The instantaneous hot water heating device comprises a singlechip microcomputer, a water inlet temperature detector, a water outlet temperature detector, an electric heating module, a first temperature display, a first communication module, a button switch module, a water pressure (flow) signal detection module, a fault detection module, an electric leakage protecting device and a water inlet valve; the gas water heater comprises a second communication module, a second temperature display, a temperature adjusting switch, a gas adjusting valve and a master controller. The system disclosed by the invention effectively solves the condition that a lot of cold water is released for a long time for water consumption at the far end of a conventional water heater or the wall-hanging stove, is low in cost, saves water-gas resources and reduces extra consumption, thereby bringing convenience to people; and hot water is obtained by an energy-saving, efficient, comfortable and simply-operated manner.

Description

technical field [0001] The invention belongs to the field of instant water heaters, and in particular relates to a dual-energy heating system with the function of rapid hot water supply. Background technique [0002] With the development of the economy and the improvement of people's living standards, the use of water heaters or wall-hung boilers is becoming more and more extensive. There are still some deficiencies in further improving people's use experience, use comfort and water and energy saving. [0003] In daily life, in order to save space and ensure the safety of water heaters, water heaters or wall-hung boilers are usually installed in the kitchen, living balcony or outdoor platform, etc., but there are more than one places where hot water is used indoors. Bowls, washbasins and showers in toilets, etc., among these devices that need to use hot water, are usually far away from the installation location of the water heater or wall-hung boiler, and the corresponding ...

AI Technical Summary

Problems solved by technology

However, the power of this instant electric heating device is relatively large, and more power lines need to be reserved for it during installation. It is very inconvenient to install in a narrow space, and it cannot reach the rated temperature when used in summer. Power, even if it reaches the rated power in winter, it cannot guarantee a large water flow, and it is difficult to ensure that people have enough hot water for comfortable bathing

Comparing the instantaneous electric heating device with the traditional gas water heater, 1 cubic meter of natural gas produces 36 megajoules of heat, while 1 kilowatt-hour of electricity produces 3.6 megajoules of heat. It takes 10 kilowatt-hours of electricity to reach the 36 megajoules produced by 1 cubic meter of natural gas. Megajoules of heat, in terms of hot water production capacity, a 7.5KW instant electric water heater is only equivalent to a gas water heater of less than 5 liters, so the instant electric heater produces the same amount of energy as a gas water heater When hot water is used, it consumes more energy

[0005] Many do not use instantaneous electric heating devices to solve the problem of a large amount of cold water when using water at the remote end, but use a small water storage electric water heater next to the water heater or wall-hung boiler or add a circulating pumping device and a small water storage The traditional electric water heater can not solve this problem very well, and it also increases the consumption of electric energy, and adding a circulating pumping device will make the cost of the whole system higher, and it is very complicated in installation and operation control, and it cannot reach to better effect
