Abstract

The electronic control of heating and plumbing systems in homes has become a common occurrence in many households. Anything from computerized thermostats to digital thermometers and humidity control, these innovation lead to increased control and manipulation of home climate control. New innovations can offer the consumer greater control over his/her house’s systems to increase comfort, efficiency and reliability. Hot water heaters heat service water to a desired temperature. Controlled by a thermostat, the heater maintains that temperature. When some of the hot water is drawn out of the tank and replace by new colder water there can be a time lag in getting the water back to the desired temperature. Prior to turning on a shower there is no way of knowing how hot the water in the system is. Conventional methods for monitoring the hot water tank temperature require the user to go to the heater and view the thermometer on the tank. This is too cumbersome for the consumer who only wants to view the water temperature before entering the shower. What is needed is a way to monitor a hot water tank remotely. The present invention is a thermocouple system inside the hot water heater, which is linked to a battery powered LCD display located near a shower.

Hot Water Thermometer

The electronic control of heating and plumbing systems in homes has become a common occurrence in many households. Anything from computerized thermostats to digital thermometers and humidity control, these innovation lead to increased control and manipulation of home climate control. New innovations can offer the consumer greater control over his/her house's systems to increase comfort, efficiency and reliability.

How to monitor a hot water tank temperature remotely?

Hot water heaters heat service water to a desired temperature. Controlled by a thermostat, the heater maintains that temperature. When some of the hot water is drawn out of the tank and replace by new colder water there can be a time lag in getting the water back to the desired temperature. Prior to turning on a shower there is no way of knowing how hot the water in the system is. Conventional methods for monitoring the hot water tank temperature require the user to go to the heater and view the thermometer on the tank. This is too cumbersome for the consumer who only wants to view the water temperature before entering the shower. What is needed is a way to monitor a hot water tank remotely.

The present invention is a thermocouple system inside the hot water heater, which is linked to a battery powered LCD display located near a shower.

Figure 1 illustrates a hot water temperature monitoring system including a hot water tank 110 that is supplied with cold water 120 and supplies hot water 130 to the house. Thermocouples 140 are positioned at various places in the tank. These thermocouples are electrically coupled to a temperature display monitor 150, which is located near the shower. Temperature display monitor 150 includes of an LCD display powered by a small battery.
