Check out Pulsacoil Replacement page for the latest system. The PulsaCoil is slightly more modern than some of the other iterations, but still lags behind the Stainless and ECO Stainless options. However, those who do have the PulsaCoil have a solid system that can be repaired and maintained as long as the internal copper cylinder is not leaking.
As explained earlier, the PulsaCoil does a great job of differentiating itself from the original. Working as a full immersion heater, this heats up the water inside a thermal store.
Using a heat sensor known as a thermistor DHW sensor , this attaches itself to the hot water outlet exchanger via the outlet piping. The heat exchanger is what makes the process from cold to hot water possible in the Gledhill PulsaCoil The pump itself regularly circulates stored hot water through the plate heat exchanger system.
In turn, this heats up the water to the expected temperature in a short period of time. You cannot legitimately buy and fit any of the older systems, as they fall behind the quality standards expected in comparison to the modern versions. However, by the same token, you can have them repaired, managed, serviced and maintained.
However, one of the major features of the PulsaCoil is the fact that it uses the exceptional proportional system to manage performance safely. This is very useful, avoiding the problem that a large temperature fall can bring to the table. When the sensor notices any kind of dip, it will kick into action. When the hot taps come on thanks to this proportional feature, you now know that they have a fair and set temperature that is never too hot nor too cold.
If this did occur we would first recommend you check the water level inside your Pulsacoil Should the temperature rise beyond a certain point, then the circuit board will shut itself off to allow a consistent temperature to be achieved. This is very useful in making sure that your PulsaCoil maintains its performance, unlike other thermal systems. In reality it slows down the pump inside the Pulsacoil to keep its consistency in providing hot water. Whilst no longer available to pick up, the PulsaCoil was a major hit in its time.
To understand why people and contractors made the choice to pick this up, it helps to know where you stand with its major features.
Some of the benefits that you can expect from using this system would include; Logically Designed. By making use of the correct balances in terms of water strength and depth, this goes a long way to making sure you get the right volume, velocity and temperature of water every time you use your Pulsa Coil. Add all of this together, and you have a system that has the perfect solutions waiting for you. Whilst diagnosing the problems can be relatively easy if you hire the right Pulsacoil expert.
Many people make the mistake of hiring a plumber, who either makes the problem worse or takes multiple visits to correct the issue with a Pulsacoil The easiest part, though, is sourcing parts. Sometimes fitting it altogether is a major issue when working yourself, so make sure you consider getting a PulsaCoil engineer specifically.
This allows for easy solutions to problems that you would likely fail at when handled on your own. This tends to occur as the heat sensors begin to lose reliability as time passes. Unfortunately, nothing can be done to stop this from occurring.
When this happens, you can look out for the little red LED device. When this flashes seven times in a second easy to notice you are being informed that your thermistor is finished and is due a replacement. This should be carried out by a professional PulsaCoil installation team. Consistency is vital for this tool to work, so thermistor damage should be a primary concern that you have corrected should you notice any weird readings. A major thing to watch out for is when a contractor has fixed your problem by bypassing the PCB which uses the sensors to give the correct amounts of hot water and has directly fed your pump with a power supply.
Because it is so efficient, both high flow rates and high pressures are available to give the best performance for both baths and showers. In most cases, the higher the cistern, the greater the pressure.
Because the Gledhill system uses the pressure from your cold water mains, those cisterns are not required. And that means there are no cisterns in the loft, which removes any worries about freezing pipes. The plastic feed tank should have been filled to the waterline by the installer at the time of commissioning.
The water level in the plastic feed tank should be checked on a regular basis, generally times a year, and topped up when necessary to approximately halfway. Once the level has been topped up or after it has been checked, ensure the lid has been securely replaced.
An optional sight glass can be fitted to the side of the feed tank, to overcome the need to remove the lid to check the water level. Do not attempt to remove or adjust any component part yourself. This should be switched on for an hour during late afternoon to provide a boost to the top part of the Thermal Store on days when a large amount of hot water is required.
If you are considering changing your electricity supplier it is important that you ensure they are able to provide at least the same tariff. Could we ask on what basis you have "moved in"? Ask seller. Ask Agent to get it fixed. Last edited: 12 Jan Agile , 12 Jan Dan Robinson , 12 Jan Really sorry, but it turns out it was a Pulsacoil A-class boiler.
I am renting, and have contacted the agency to look at it, though I thought I'd have a look it myself first as I'd like to understand how equipment work and it makes fixing problems even easier in the future.
Also it helps if I understand it properly as this may prove useful for the engineer who comes to fix it. I haven't found the reset button, but I assume because Daveydub gave instructions relevant to the pulsacoil? Having looked at the booklet for the pulsacoil A-class boiler, it has a display panel which shows the status of the boiler. When I have both switches on, the status illuminates for both off peak and on peak supply present, and when I switch off the off peak switch, the off peak supply present does not illuminate.
Also, when I have them both on, and open the tap, the bottom sensor calling light illuminates, which means the bottom off peak heater is working. Additionally, I've checked my electricity meter, and I have a single rate meter, so I'm not sure of any benefit I can gain with the off-peak supply option. I'm thinking, maybe nothing is wrong with it, and it was set-up with no off-peak timer because the meter is a single rate meter that doesn't measure peak and off peak.
Though not sure why it was set up to only be powered on when the boost switch is on. Maybe I should be using the boost as normal for the top heater , and if I have high demand, then switch them both on? Sorry I'm just thinking aloud here, not sure on how best to use the boiler, and if it does actually have a problem or not.
I've uploaded a few pics if that helps in anything. Ibzo , 12 Jan I am not surprised the bottom heater probably doesn't work. Unless you also have storage heaters you would probably not save money by swapping to economy 7 once you have both heaters working.
A look at uswitch or similar will help you decide on this. Daveydub , 12 Jan
