Abstract
A device for a water heater has a main waterway 8 closed by a wax capsule 2. Hot water initially passing through a bypass channel past an adjustment screw 1 heats the capsule causing it to open the main waterway 8. A flow rate adjuster 3 is provided. The device is held on to pipe-work by compression fittings 4.
Description
I
Combi-Saver This invention relates to a water and energy saving device for instantaneous water heaters.
On opening the hot water tap connected to a Combi or multipoint water heater, there is often a significant delay before any hot water arrives at the outlet.
On a current system, with a Combi boiler, the standard practise is to open the tap at a high flow rate. Due to this high flow rate and waiting period, a considerable volume of cold water is wasted.
Alongside water wastage another disadvantage occurs as a result of the inability of the heat input from the boiler to rapidly attain the target temperature, due to the volume of water passing through the heat exchanger. This wastes gas and electricity.
The invention involves an adjustable bypass. This allows a minimum flow rate to be established in order to activate the hot water flow switch within the boiler.
A Combi boiler will fire on high gas, and, with a low water flow rate, will, rapidly reach toward the desired temperature.
A wax capsule is in contact with the water and is designed to open when the temperature reaches approximately 35-40 C allowing the full flow of hot water.
A method of limiting the movement of the wax capsule will also be included as once the maximum flow rate, for the boiler, has been exceeded the water temperature rapidly decreases to below the desired target temperature.
Householders are increasingly concerned about high utility-gas, electricity and water charges. Many households in addition, are watermetered. This device will reduce charges in these areas.
Environmentally, this device is very important due to its energy efficiency. It also means that less water needs to be needlessly recycled and for there to be less of a demand on gas and electricity supplies- an ever growing concern at this time.
An example of the invention will now be described by referring to the accompanying drawings- FIGURE 1 shows the wax capsule in the closed (low flow rate) position.
FIGURE 2 shows the wax capsule in the fully open (high flow rate) position.
In figure 1 the water is allowed past the bypass adjustment screw 1. As the water temperature is low the wax capsule 2 keeps the main waterway closed. The maximum flow-rate adjuster is shown at 3. The unit is held on to the pipe-work with compression fittings 4 and the direction of flow arrow is at 5. Arrow 6 shows the resulting closure of the main waterway.
In figure 2 we see the wax capsule 2 in the hot position and the main waterway 8 completely open. The maximum flow adjuster 3 limiting the movement to set maximum flow rate. Arrow 7 shows direction of movement of the wax capsule clearing the main waterway.
Claims (1)
- Claims This device consists of two waterways and a temperature sensitivewax capsule. When the hot water taps connected to the valve are opened water, at first, passes through an adjustable bypass channel. A wax capsule is in contact with the water passing through the bypass channel at a predetermined temperature-approx 35 C - 40 C. The main waterway is cleared allowing full water flow to the hot water outlets.CLAIM 1 The bypass channel is a separate channel to allow water at an adjustable rate to bypass the main waterway channel, but still pass over the wax capsule.CLAIM 2 The wax capsule is temperature operated to open the main channel at a higher temperature and close at a low temperature.CLAIM 3 The main channel allows full flow rate through the valve passing across the wax capsule.CLAIM 4 An adjuster is insitu to allow restriction of maximum flow rate.CLAIM 5 The bypass channel is a separate channel connected to the main channel up and downstream of the wax capsule.CLAIM 6 This device can be made from copper, copper alloys, plastic or composite material.CLAIM 7 Alternative methods of limiting maximum and minimum flow rates may be used.CLAIM8 This valve is designed to be a low cost unit but could at extra cost be designed with a modulating coil and temperature sensor.
