Abstract
The vent safe device comprises a sensor 4 that monitors the temperature in the vent pipe 2 on a hot water cylinder 3 or the cold water temperature (fig 2, D) of a combined cylinder and tank (fig 2, C). If the temperature becomes too high, it shuts down the power to a heating element such as immersion heater 1. A manual button may be used to reset the device. Overheating of the water, possibly due to thermostat failure, is prevented, reducing the risk of scalding.
Description
Vent Safe This invention relates to a device for the safety of cold water storage tanks and hot water cylinders.
A particular form of heating water is by the use of an immersion heater. This is an electric heater inserted into the side of a cylinder or tank.
It is a possibility that these immersion heaters can fail to turn off. This can lead to boiling water travelling up the vent pipe and into the cold water storage tank above.
This can then lead to the malfunction of the tank resulting in boiling water being spilt uncontrollably. Another result of this is scalding water being delivered to the taps.
The present invention is a fail-safe system to prevent this. It can be installed to all types of hot water systems. When the temperature in the vent pipes reaches a set limit the device cuts the power to the immersion. This device then needs to be manually reset. When the device has cut the power the water will cool down to a safe temperature.
The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows a hot water cylinder with a cold water tank above, the device is fitted to the vent pipe and wired to the electricity supply and immersion heater.
Figure 2 shows a combined hot water cylinder and cold water storage tank, the device is fitted into the cold water storage tank.
In figure 1, the device 4 is installed in the vent pipe 2. It is a 22mm compression tee with a thermostat pocket on the branch. Inside the unit 5 is an overheat thermostat.
The sensor from the overheat thermostat is located in the sensor pocket at 4. The water in the cylinder 3 is heated by the immersion heater I. The immersion heater I gets its power from the switch 6, with the invention in place the wire will pass througI the unit 5. If the immersion heater I fails to shut down, the sensor in the vent * pipe 4 will cause the overheat thermostat in the unit 5 to cut the power. The result will be the cooling of the water back to a safe temperature. The device now has to be manually reset which gives the possibility to rectif' the fault without an accident.
Figure 2, this shows a combined hot water cylinder A and cold water storage tank C. The immersion heater B is protected in the same way as figure 1 except the sensor D is located in the cold water storage tank C. The sensor D monitors the temperature of the water in the tank C, if this gets to hot it will trip the overheat thermostat in the unit E, cutting the power which is coming from the original source at F.
Claims (4)
- Claims 1. A single purpose fail safe device to prevent scalding and product failure due to overheating of water.
- 2. A safety device according to claim 1, in which the vent pipe of a cylinder is monitored with a pocket sensor to control over heating.
