Circular preheating system

Abstract

The invention provides a circular preheating system. The circular preheating system comprises a water heater, a cold water pipe and a hot water pipe connected to two sides of the water heater, and a circular preheating device connected to the hot water pipe; the circular preheating device comprises a heating mechanism, a preheating water inlet pipe and a preheating water outlet pipe connected to two ends of the heating mechanism, and a circulating water pump arranged on the preheating water inlet pipe; the preheating water inlet pipe and the preheating water outlet pipe communicate to two places of the hot water pipe; and the preheating water inlet pipe, the heating mechanism, the preheating water outlet pipe, the hot water pipe and the preheating water inlet pipe communicate in sequence to form a circular preheating pipeline. The circular preheating system can realize water heating during starting, can be matched with a general gas water heater for use, is convenient to popularize onthe market, and improves the product popularity and the environmental adaptability.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a circulating preheating system. Background technique [0002] Ordinary gas water heaters need to wait for a period of time before they can produce hot water. This has always been one of the biggest pain points plaguing the gas water heater industry. It not only affects the use comfort of users, but also wastes water resources, which has become a problem that the industry needs to solve urgently. In the traditional technology, a more common solution is to add a circulating water pump inside the ordinary gas water heater, so that the external pipeline and the gas water heater form a circulating water circuit. The cold water is preheated, so as to achieve the function of hot water when the machine is turned on. However, ordinary gas water heaters cannot realize the functions of circulating water flow and preheating in advance because there is no driving water pump inside. T...

AI Technical Summary

Problems solved by technology

However, ordinary gas water heaters cannot realize the function of circulating water flow and preheating in advance because there is no driving water pump inside.

Thereby make adopting this solution and just need to separately develop a brand-new gas water heater model with circulation preheating function, the cost is higher

Moreover, for users who have purchased ordinary gas water heaters, the function of hot water can only be realized by replacing the new gas water heaters with preheating function, and the old gas water heater users cannot be taken into account.

Therefore, this novel gas-fired water heater that realizes instant hot water when starting up is not easy to popularize in the market, and the popularity and environmental applicability of the product are not high.
