Gledhill pulsacoil a class manual

Other benefits of the PulsaCoil Stainless include the fact that the immersion elements are situated in the same primary water at all times and this water is not renewed so no scaling takes place, even in hard water areas.

As the cylinder can utilise the off-peak electricity supply it keeps the running costs for the householder down to a minimum. Pulsacoil Stainless thermal stores do not require any annual maintenance, unlike with an unvented cylinder.

PulsaCoil Stainless. A thermistor heat sensor is attached to the domestic hot water outlet from the plate heat exchanger. When the thermistor records a fall in temperature, the circuit board inside the Gledhill Pulsacoil A Class runs the pump. The pump circulates stored hot water through the plate heat exchanger, heating it, and the circuit board turns it off again when the thermistor reports a temperature rise. This system is proportional.

The bigger the temperature fall seen by the thermistor, the faster the circuit board runs the pump. This way the designed flow temperature of 52 degrees Celsius, I think can be maintained at almost any flow rate when a hot water tap is turned on, or shower is turned on.

The Gledhil PulsaCoil A Class is a relatively new model so unlike the other models previous to it, below are common fault when we are called out to Gledhill Pulsacoil A Class repairs:. On some early batches of Gledhill Pulsacoil A Class this can light flash during normal operation, even when there is no fault present, and the label incorrectly suggests a fault has occurred.

Also it can occur if the relpol relay has been removed from the Gledhill Pulsacoil A Class assembly rail. There is no particular need to do this unless more hot water is needed immediately. The unit will re-heat automatically at night if the econmoy 7 timer is set correctly or the external timer has been set correctly. This is not the right way to have your Gledhill Pulsacoil A Class operate. A short section of wiring to the Off-Peak heater on a Gledhil PulsaCoil A Class has a habit of burning out, along with the power relay.

When this happens the red light flashes and the unit only produces hot water if the user presses the black button next to the flashing red light this might not work either in some cases as the burnt relay sits next to another relay which could have been damaged to inside the Gledhill Pulsacoil A Class. The burned out section of wiring and relay can be easily replaced.

If an undersized system is installed, this will not give you all the hot water you are likely to need. An upgraded Pulsacoil A class system maybe required. It would be so much of an upgrade but a replacement for the latest model. And if you do decide to have a replacement installed we recommend you advise the installer that the current sized unit does not give you enough hot water.

You can call us to find out more about the latest systems available to you and the pros and cons. The Pulsacoil A Class system will ensure that the energy it needs is minimised. This avoid costly use of electricity by taking advantage of off-peak tariff.

It also does not allow the on-peak tariff to power the top element at the same time. As mentioned before. The Pulsacoil A Class is connected directly to the cold mains water supply and therefore even the hot water supply is pure high quality water each time you use it.

With other standard systems which have a cold water supply cistern in the roof space, there is always the chance that the tank can become contaminated by dust, birds and or insects.

This could lead legionnaire. The information below could help if you are experiencing faults with your system. Please read the information carefully. If you need us to send an engineer to you, please call.

This specific contactor is not sold by us as it tends to burn. The burning of this contactor can cause a fire and in some cases has. Instead we recommend it be replaced with a Relay Retro Kit. A picture of the old contactor is below. Please also note it could damage cables inside the system.

If you do have the old contactor inside your Pulsacoil A Class, we would recommend you replace it. It could cause more damages and work out to be much more expensive.

We have come across situations where the Pulsacoil A Class system is overheats. This most likely will be one of four reasons. Each reason is unique, so please read carefully. The contactor inside the Pulsacoil A Class is burning. This will cause the contactor to stick in the on position even when not needed.

This most likely will be the off peak contactor. The overheat sensor inside the Pulsacoil A Class has failed. When the Pulsacoil A Class reaches a certain temperature it switches off the contactors. If the sensor has failed it will still think it needs heating. This then causes the water in the cylinder to boil. The steam released will damage walls and doors. Please keep an eye out for this as its not obvious all the time. The immersion elements have been bypassed inside the Pulsacoil A Class.

This sounds unlikely but we have come across this situation. On some visits we have found that another company is unable to establish the fault. So what they do is bypass the contact which is controlled by the PCB.

This leaves a permanent supply onto the element. They then reduce the time on the timer. This is very dangerous. If you believe this has been done call us immediately. We would recommend you switch the system off. This reason is very unlikely but does occur. If this is the case have it replaced. Before having it replace, check the settings are on A3. Check the header tank above the Pulsacoil A Class is filled. This is overlooked many times. If it is not, there will not be sufficient water being pumped around the plate heat exchanger.
