Problems solved by technology

[0005] The second flaw involves two kinds of gas waste
The second type of gas waste occurs because many users only turn on the hot water tap when washing their hands, wash with cold to lukewarm water at first, and then turn off the water tap
In that case the gas is only used to go through the start-up phase while the hot water is left in the pipes which cools down afterwards and is thus wasted

Embodiment Construction

[0116] figure 1 A water heating system 10 is shown in a first embodiment comprising a tankless gas water heater 12, preferably 4, 5 or 6 star. Upon detection of water flow through the water heater 12, the burners in the water heater 12 are automatically activated. The system 10 also includes a (buffer) water storage tank 14, preferably having a volume of 4-50 liters. Box 14 is enclosed by insulating material 16 . Water heater 12 has an inlet 18 and an outlet 20 . Tank 14 has an inlet 22 and an outlet 24 . The inlet 18 of the water heater 12 is connected to a mains water supply pipe 26 . The outlet of the water heater 12 is connected to the inlet 22 of the tank 14 via a pipe 28 . Outlet 24 of tank 14 is connected via tube 30 to a user-controlled outlet device, such as a hot water tap (not shown).

[0117]When the user initially turns on the tap, water flows from the water supply pipe 26 into the water heater 12 where it is heated by the gas burner. The hot water then flo...

Abstract

A hot water system (10) comprising a water storage tank (14) and an instantaneous-type water heater (12). The water storage tank (14) has an inlet (22) and outlet (24). The instantaneous-type water heater (12) has an inlet (18), in fluid communication with a mains water supply (26), and an outlet (20), in fluid communication with the inlet (22) of the tank (14). The water heater (12) energises in response to a flow of water through the water heater (12).

Description

technical field [0001] The present invention relates to a water heating system and method of operation thereof. [0002] The invention has been primarily developed for tankless gas water heaters and will therefore be described hereinafter with reference to this application. However, the invention is not limited to this specific field of application, but can also be used in instantaneous electric water heaters. Tankless water heaters are also known as tankless heaters in the United States. Background technique [0003] Known tankless heaters have an inlet connected to a water supply and an outlet connected to, for example, a water tap. The flow of water through the heater automatically activates the gas burner or electric element within the heater. This known structure has two drawbacks. [0004] The first flaw concerns the waste of water. When a user turns on a hot water faucet, the user must wait for the water supply to be heated and for all unheated water in the pipe ...
