Abstract
A temperature sensor installed in the cold water storage tank of a domestic water system. If the water in the hot water tank expands, causing an excessive amount of hot water to rise through the expansion pipe from the hot water cylinder into the cold water cylinder, this is detected by the temperature sensor. The temperature sensor then triggers an alarm which may have an audible or visual indicator. This allows the condition to be detected before damage is done to the cold water tank. The sensor may be made of copper. It may be permanently attached to the alarm via a hole in the ceiling if the cold water tank is in the loft space. The alarm may have a low battery indicator.

Water storage tank heat sensor
In the United Kingdom a large number of domestic hot water systems comprise of a cold water storage tank in most cases located in the loft space delivering water to a copper cylinder below which is heated by several different means including an electric immersion heater. The hot water is then delivered to the taps.
There has recently been 2 reported cases where water has overheated in the cylinder and expanded into the cold water storage tank.
Most modern storage tanks are made of plastic and only designed for cold water.
If these tanks are not supported properly and become filled with hot water the plastic would soften and buckle and eventually collapse.
It is believed the reason for overheating is that the thermostat in the immersion heater in the hot water cylinder failed, allowing the heating element to continually heat the water causing it to expand into the cold water storage tank above in the loft space.
As the hot water expanded into the storage tank the cold water was being replaced back into the hot water cylinder below.
The storage tank finally filled with hot water, buckled and collapsed allowing the hot water to cascade through the ceiling onto the occupants below resulting in terrible injury.
2
To help to overcome this problem this idea is to install a small heat sensor into the cold water storage tank connected to an audible/visible alarm in a suitable position so as can be seen or heard by the occupants.
The advantage of this would be if the immersion heater thermostat fails allowing the heater to continually operate without switching off, when the water in the cold storage tank reaches a certain temperature the alarm will activate alerting the occupants of the danger who can then switch off the immersion heater to prevent any further overheating.

An example of the invention is described in the accompanying drawings.
Figure 1 shows a basic typical layout of a gravity fed domestic hot and cold water system.
Figure 2 is the same layout showing an example of the heat sensor which is placed submersed in the cold water storage tank.
This is shown connected to the alarm which is positioned below the ceiling or floor.
A description of the invention is as follows,
A heat sensor sealed in a copper tube connected to the alarm by a small copper pipe.
The sensor would be set at a suitable temperature and when reached would send a signal to the alarm which is then activated.
When activated the alarm would sound with either a buzzer or continual or intermittent bleep and a visible flashing light.
The heat sensor would be permanently fixed to the alarm with a suitable length of pipe and be small enough so as to feed through a small hole made in the ceiling, passed through and located in the tank.
The alarm would then be offered up to the ceiling and fixed with suitable fixings.
The alarm would be in a plastic housing and of a size and colour to blend in with any decor.

Claims (5)
1. A water storage tank heat sensor immersed in the cold water storage tank which when senses a set temperature sends a signal to an attached alarm which in turn is activated.
2. A water storage tank heat sensor according to claim 1, the sensor being made in copper with a copper tube permanently connected to the attached alarm.
3. A water storage tank heat sensor according to claim 1, the sensor being permanently attached to the alarm and being small enough so as to pass through a hole in the ceiling causing minimal damage.
4. A water storage tank heat sensor according to claim 1, the alarm being battery operated with the sound of a buzzer or bleep being continual or intermittent and having a visual flashing light when activated.
5. A water storage tank heat sensor according to claim 1, the alarm having a low battery warning indicator with a test button and being of a suitable size and colour so as to blend in with any decor.
