Abstract
A warning sensor unit may be fitted to any part of the condensate pipework installation of a central heating condensing boiler system where the boiler is being used to provide domestic hot water and hot water for a wet radiator central heating system. The warning sensor unit operates by detecting a blockage in the condensate pipe and sends out an electrical signal to the boiler control panel and the control panel immediately places the boiler in a stand by position of safety. The trigger mechanism may be provided by, for example, metal probes, a microswitch, a pressure switch or a float switch.
Description
APPLICATION TO REGISTER A PATENT
STEP 1 The preparation of a UK Patent Specification (a) TITLE The invention is referred to in this application as a WARNING SENSOR UNIT
(b) BACKGROUND
This invention relates to the problem that can arise in a drain off condensate pipe which forms part of a central heating condensing boiler set up -the boiler being used for the purposes of providing domestic hot water and hot water for a wet radiator central heating system.
1. l'hrough the function of a condensing boiler an emission of condensate water is created in the heat exchanger unit of the boiler when the boiler is heating up water for either domestic hot water or hot water for a wet radiator central heating.
2. Within the design and installation of the boiler the condensate water as it is created is allowed to drain to an outlet point, usually at the bottom of the heat exchanger unit.
3. The condensate water is then drained away ( via gravity) from the boiler itself to an outside galley or discharge drain via a pipe connected to the boiler, usually 22mm diameter of upvc or as recommended by the boiler manufacturer which is referred to as the condensate pipe.
4. In the event of the condensate pipe carrying the condensate water away from the boiler becoming blocked (for whatever reason: frost, vandalism etc. ) and the condensate water is unable to drain away from within the boiler, the condensate water will back up into the boiler exchanger unit itself creating a flood situation which could result in a hazardous and dangerous circumstance.
(c) STATEMENT OF INVENTION
I. To overcome the problem as described under the section BACKGROUND, the invention comprises of a WAR1'JING SENSOR UNIT installed as part of the condensate pipe.
2. The invention ( WARNING SENSOR UNIT) and its introduction as part of the condensate pipe is for the purpose of detecting the backing up (through blockage) of condensate water within the condensate pipe and sending an electrical warning signal to the boilers control panel to be act upon before condensate water can reach the heat exchanger unit within the boiler.
(d) ADVANTAGES There is a recognised need to prevent condensate water from backing up into the boiler which if allowed to occur could have both material and human consequences 1. The filling up of the beat exchanger unit within the boiler with condensate water creates a danger and hazard in that:-a. Condensate water could come in contact with the heat source to the boiler ( ie high intensity flames) and cause the boiler to malfunction and eventually cut out.
b. Condensate water flooding through the heat exchanger unit within the boiler could result in an electrical short and a possible fire hazard.
c. With the heat exchanger unit disabled through flooding by condensate water any frost stat linked to the boiler which is used as a fail safe device to operate the boiler below set temperatures would not operate and expose the boiler to freezing and serious damage.
d. The condensate water is acidic and is harmful if coming into contact with skin and eyes.
2. The introduction of the invention as part of the condensing boiler installation set up has the advantage of preventing these occurrences and avoid costs in repairs and harm to individuals.
3. Users of the boiler can be alerted of a danger / malfunction to the boiler system through audible alarms and visible flashing lights attached to the exterior of the boiler casing.
(e) INTRODUCTION OF DRAWINGS (as attached -2no drawings) Drawing no 1 of 2 Shows a set up of a typical condensing hot water I central heating boiler with a condensate pipe outlet installed in accordance with the manufacturers recommendations.
Shows also the same arrangement but with the WARNiNG SENSOR UNIT installed (alternative positions are possible) Drawing no 2 of 2 Shows the details of the WARNING SENSOR UNIT in the condensate pipework system in accordance with the invention to which this Patent Application relates.
(f) DETAILED DESCRIPTION
1. The invention works through a mechanism forming part of the WARNING SENSOR UNIT which sends out a low voltage electrical signal to the boiler control panel warning of the pending danger through a backing up of condensate water within the condensate pipe ( caused by an undescribed blockage) 2. The mechanism within the WARNING SENSOR UNIT can vary, either being electrical or mechanical (examples being: micro sensor switch, pressure sensor switch, float switch, sensor probes) and the switch is operated by the condensate water filling up within the condensate pipe until it reaches the WARNING SENSOR UNIT.
3. Within the boiler control panel the electrical signal is received and transferred to a command to turn off the boiler leaving it in a standby position.
4. The cause of the water blockage within the condensate pipe can be identified and water drained from the pipe by dismantling or the provision of a drain off point within the pipework and the boiler control panel re set to its original operation mode.
Claims (8)
- CLAIMSThe STATEMENT OF INVENTION describes the purpose of the invention and which Claims to be:- 1. A Warning Sensor Unit fitted either at the immediate connection of a condensate pipe to a condensing boiler or into any part of the condensate pipe that will detect a hazardous build up of condensate water within a condensate pipe and send out an electrical warning signal to the control panel of the condensing boiler.
- 2. A Warning Sensor Unit according to Claim 1, in which the warning signal to the control panel of the condensing boiler is provided through a sensor fitted within the Warning Sensor Unit.
- 3. A Warning Sensor Unit according to Claim 2, in which the sensor is activated by a build up of condensate water backing up the condensate pipe.
- 4. A Warning Sensor Unit according to Claim 3, in which the sensors trigger mechanism is two metal probes which are capable of completing a low voltage electrical circuit when activated by condensate water in the condensate pipe filling up and over the probes.
- 5. A Warning Sensor Unit according to Claim 4, in which the sensors trigger mechanism within the Warning Sensor Unit can also comprise of:-an electrical micro switch activated by the condensate water filling up in the condensate pipe.an electrical float switch activated by the condensate water filling up in the condensate pipe.an electrical pressure switch activated by the condensate water ifiling up in the condensate pipe.
- 6. A Warning Sensor Unit according to Claim 4, in which the low voltage electrical circuit is provided from and linked to the power source within the condensing boiler control panel.
- 7. A Warning Sensor Unit according to the preceding Claims, that when activated will send an electrical warning signal to the condensing boiler control panel -the received signal would then be acted upon within the control panel by shutting down and placing the boiler in a standby position of safety.
- 8. A Warning Sensor Unit according to the preceding Claims, that can be fitted as part of the condensate pipe installation and be removable for any maintenance or replacement.
