How Do You Check the Header Tank Level on a Gledhill PulsaCoil Water Cylinder?

With an unvented water cylinder, there is a need for a header or feeder tank. This helps keep the system primed and working properly. However, if the level of water within the tank drops too low, you may experience a wide range of issues with your hot water system, including pressure drops, temperature drops, and more. If you have a Gledhill PulsaCoil water cylinder, you have a plastic top up cistern attached to the water cylinder. How do you check the header tank level? It’s actually not very complicated.  1. Locate the Header Tank The first step here is to locate the header tank and ascertain its condition. Note that Gledhill actually offer an optional sight glass for the plastic header tank that allows you to see the water level without doing anything else. If your tank is so equipped, simply look at the level of water in the sight glass. If it is low, top off the tank. If it is not, check it again later in the year.  2. No Sight Glass If your system does not have a sight glass, you’ll have a little more work to do. You will need to remove the plastic top to the header tank. Then, using a handheld torch (if there is not enough ambient light), check the water level within the tank. There is a fill line marked on the side of the tank so all you need to do is check the level against that mark to determine if you need to fill the tank. If you do not currently have a sight glass, but you would like one installed, Easy Flow may be able to install one for you to make maintaining your water cylinder simpler and easier. 3. Fill the Tank (If Necessary) The Gledhill PulsaCoil has a manual fill header tank. What that means is you must top up the tank regularly by hand in order to maintain proper operation of your system. You will simply need to add water to the tank until it reaches the fill line, which is roughly halfway up the wall of the tank.  4. Close the Lid Once you have checked the water level and/or topped off the water in the tank, simply replace the lid and make sure that it is well sealed. Leaving it loose could speed up evaporation and reduce the level of water in your tank. How Often Should You Check the Header Tank Level? While it is necessary to check the header tank water level regularly, you do not need to do so very frequently. Gledhill recommends three to four times per year. It should also be part of your annual service. As you can see, there is not a lot involved with checking the header tank unit. The most important thing is to ensure that you do not forget to do it regularly.

Help! My Water Is Only Lukewarm. What’s the Problem?

When you open the hot water tap at your sink, you expect to be rewarded with a stream of piping hot water for your washing needs. The same thing applies when you set foot in the shower, or when you wash a load of clothes on the hot setting. However, there’s a chance that when you open that tap, the water that comes out will be lukewarm rather than hot. What’s the problem here? Actually, it could be one of several different issues. Check the Thermostat The first thing you need to do is to check the thermostat on your water cylinder. It should be located between halfway and one-quarter up the cylinder from the base. It will most likely be a plastic box with a round dial on it, although newer models might have a digital thermostat instead. Check that the thermostat is set for between 60 and 65 degrees. If it has been bumped somehow, the temperature could have been accidentally set lower than this, which would give you lukewarm water. If the thermostat is correctly set, the problem might still lie with it. There is a chance that the thermostat is faulty and will need to be replaced. However, the issue here is that your cylinder actually has two thermostats, and you will need to determine which one is bad before it can be replaced. Easy Flow can help do that. Check the Power Supply If you have a thermal store water cylinder, it can maintain the temperature of the water inside it for a long period even without a source of heating. The water will slowly cool down, eventually reaching lukewarm before it becomes cold. If the thermostat is not the problem, check the power to the system. The place to do this would be at the breaker that controls the water cylinder. If it has been tripped, then no power is getting to the system. Flip it back into position and see if the water heater turns back on. Note that a tripped breaker is often a sign that there’s a deeper problem that needs to be addressed, as circuit breakers are designed to trip in the case of over-power situations where the cylinder is drawing more electricity than it is designed to handle. Check the Fuses Depending on the water cylinder model in question, you will have one or more fuses that control unit operation in addition to the circuit breaker. If one of these fuses is blown, your cylinder will not receive electricity and will not operate. The good news is that replacing a blown fuse is usually not a difficult process, although locating the fuse in the first place can take some time. Failed Immersion Heater Finally, there is a chance that one of the immersion heaters in the cylinder has failed. If this happens, the remaining heater will still attempt to warm the water, but it will not be able to get it up to full temp and the result will be lukewarm water. In this case, the faulty immersion heater will need to be replaced. There you have them – some of the more common reasons that you could experience lukewarm water from the tap rather than hot water.
