  • How does a central heating pump work?

    central heating pumpCentral heating pumps are responsible for the pumping of hot water around your central heating system. These pumps will deliver hot water around your building from the boiler, to the radiators, and back to the boiler again.

    When water travels from your boiler it’s hot, and as it makes its way through your pipes and to your radiator it loses heat. It is the heat from this pumped hot water that is responsible for the heating of the room. The water in the radiator then cools and travels to the boiler to repeat the process again. The whole purpose of a central heating pump is to make this procedure far more efficient and therefore effective.

    Some heat pumps come with a number of features & benefits that can really help increase the efficiency of it. One of these features is a wet rotor pump, which is specifically designed in such a way that it provides consistent pressure in your pipes. A huge benefit of this kind of pump is that it can automatically adjust the central heating pumps performance based on the demands of the system, which can greatly decrease the running costs of your central heating.

    Sometimes problems occur within a pump, but these are easily fixed for the most part. Here are some common problems when it comes to central heating pumps and the action you can take to fix them.

    The central heating pump makings a rattling noise against the wall

    Be sure to check if the pump is secured properly, if the screws holding it into place are loose be sure to tighten them.

    The pump doesn’t heat all of the radiators

    Turn the pressure up, though be aware this should only be done if the problem is upstairs. There could also be a problem that the pump is old and doesn’t have the power that it used to in order to be able to pump the water round the system.

    Noises from central heating

    There may be air in the pumps, be sure to bleed the radiators to rectify this.

    The pump casing is hot

    You may need to get the pump replaced, the pump casing can be warm but if it is too hot to be able to leave your hand on then there is a clear problem.

    The pump is making a lot of noise

    If you can hear a knocking noise within the pump, there is a good chance something has become misplaced inside of it. You will need to replace it.

    The pump isn’t making any noise at all

    It may be dead. Check if the pump has been turned off, or if a fuse near the pump has blown.

    Boiler heating the hot water but not the central heating (or vice versa)

    This is a common problem when the heating has not been used for a while and it has a simple solution: simply give the central heating a gentle tap. This can be more effective than you realise as it can free a sticking valve.

    At Pump Sales Direct, we are fully equipped if you need to replace your central heating pump. We have a wide variety available to choose from that will suit anyone’s needs.

  • FAQ: Submersible water pumps

    submersible pumpsHere at Pump Sales Direct, we are proud to offer a range of quality Submersible pumps. These pumps are designed to be underwater and therefore are perfect for outdoor water projects, whether it be a pond, a fountain or a pool. Understandably, not everyone is going to have impeccable knowledge when it comes to pumps, but at Pump Sales Direct, we consider ourselves experts on the subject. Here are a few common questions & answers related to submersible water pumps.

    How much of the pump is actually submerged in water?

    Everything. A submersible pump’s purpose is to be completely submerged in fluid, including the motor which is fixed to the body of the pump.

    How does the motor function when surrounded by water?

    While it is true that when a motor is exposed to water it can result in short circuits, the pumps are designed to be immersed in water. The machinery possesses a set of seals that fully ensure liquid is kept out of the motor.

    Can the pump work in dirty water?

    It depends. We stock two types of pump: clean water pumps and dirty water pumps. The clean water pumps are used for generally clean water sources, such as pools or cisterns, however, they cannot pump fluids that contain particles greater than 1mm in size. Dirty water pumps, on the other hand, are capable of this kind of task.

    Can dirty water pumps be used in clean water environments?

    Yes, there is no problem with doing this. Also, you will have the additional benefit of being able to filter out unwanted contamination, such as, mud or salt.

    What are the different application to these pumps?

    There are many applications for these pumps. A single stage submersible pump (one impeller) is used in sewage pumping, industrial pumping, slurry pumping, drainage and pond filters. A multiple stage submersible pump (twin impeller) is typically lowered down into a borehole and is generally used in domestic, business or industrial settings where water extraction is needed, as it creates artificial lift.

    What are the common reasons for pump failure?

    Generally speaking, the typical reasons for pump failure range from: the tank size being too small for the job it has to perform, improper choice of pump, running dry and short cycling.

    Can I install a pump myself?

    While you can do this yourself, we would recommend hiring a professional as the whole unit must be installed with the greatest of care. This is also true for servicing, as the pump will need to be extracted from the ground for a proper examination.

    How reliable are they?

    Submersible pumps have a stellar reputation, they are well-known for their reliability and for posing little to no problems given the proper care. Sometimes, pumps can last approximately 20 years without needing servicing.

    Can submersible pumps be used in professional, industrial settings?

    Yes. These pumps are used in various settings, including: seawater, firefighting, well-drilling, offshore oil drilling rigs, sewage treatment plants and irrigation systems.

  • How to lower your heating bill in 2017

    Lower bills with Grundfos central heating pumpWinter is an expensive time for everyone. Not only are our bank accounts depleted with the December Christmas frenzy, our bank accounts take an additional hit in the way of energy bills. Heating your home is a necessity, but it doesn’t always have to be an expensive one. Here at Pump Sales Direct we have compiled a list of some tips to help you keep those heating bills in check.

    1. Be selective with which rooms you heat

    Just because you decide to have the heating on doesn’t mean every room in the house has to be warm. If you have a spare bedroom or any room that you simply don’t use, turn the radiator off in there.

    2. Insulate your home properly

    You would be surprised at the amount of heat that you may be losing through the walls of your home. It’s a fact that over 60% of your home’s heat can be lost if not insulated. It may seem like a lot of money to spend, but think about how much you’ll be saving in the long run.

    3. Get yourself a Grundfos central heating pump

    Central heating pumps are vital in preventing wastage of hot water within your home. The Grundfos central heating pump range we offer are the most advanced and energy efficient circulators on the market. They have variable and fixed speed operation, incorporated power display units and ‘A’ energy rating (the lowest consumption rating and low noise operation). If you already have one, it maybe time to replace your pump.

    5. Adjust your thermostat to suit the weather

    Shaving a few degrees off your thermostat on particularly warm days can make a significant difference in saving wasted energy. If the day turns out to be warmer than expected, turn it down, or even better: turn it off. Find out how you can control your heating from your iPhone.

    5. Invest in a humidifier

    While it might sound like a bizarre tip, but adding moisture to the air creates humidity which feels warmer and can actually keep the heat in better. Another way to add humidity to your home is through decorating your house with plants, they’re not just for show!

    6. Don’t overuse your exhaust fans

    While they can be great for clearing steam when cooking or showering, if you leave an exhaust fan on for too long it will suck the warm air out of the room. Make sure you use it sparingly and turn it off when you’re finished.

    7. Utilise your blankets & clothing

    Sometimes wrapping up warm can be a fantastic (and much cheaper) alternative to reaching for the thermostat. Wearing your jumpers indoors in the daytime and throwing additional blankets on your bed at night can keep you warm and toasty.

    8. Make use of the sun

    Natures natural source of heating, be sure to keep your curtains open in the daytime to let the heat in; especially in the south side of the house where you are more likely to get direct sunlight. Remember to close the curtains at sundown so you can trap the heat within your home.

  • 10 tips to prevent frozen pipes this January

    sumps pumps prevent freezing pipesThe coldest months of the year are January & February, and with that bitter chill comes the risk of the pipes in your home becoming frozen. When pipes become frozen there is a chance of them bursting, which can be catastrophic to a building. Fixing them is a long and arduous process that leaves you with a lengthy bill to pay at the end. Obviously, nobody wants to be caught out by this and you will want to do everything you can to prevent it – so we at Pump Sales Direct have done our research to compile helpful tips to stop your pipes from freezing.

    1. Check outside taps

    Be on the lookout for any leaks or drips coming from your outside faucets, if they have either of these, they will need repairing. The cost of this will be miniscule compared to what you must pay if it bursts.

    2. Take the hose out of the garden tap

    When you leave a garden hose connected in the winter, you run the risk of water in the hose freezing. This may not sound serious, but the ice in this hose can expand and, in the worst case scenario, can even lead up to the connecting faucet – which can cause it to freeze and break.

    3. Utilise outside shut-off valves

    Some homes are equipped with shut-off valves that allow you to turn off the water leading to any outside taps and drain the water from the pipes. Incredibly useful since outside taps aren’t necessary during the winter.

    4. Check the quality of your sump pump

    The purpose of a sump pump is to keep the underneath of your house dry, so obviously this is key to keeping any unwanted water away from your pipes. Located in your basement, make sure your pump is working by tipping a bucket of water into the sump pit, it should pump the water out, then turn itself off. We provide a range of quality sump pumps here at Pump Sales Direct.   

    5. Clean debris from the sump pit

    Another reason for your sump pump not functioning properly is improper cleaning of the pit it’s situated in. Clean out anything that shouldn’t be there, like rocks, and test it to make sure that it functions properly.

    6. Keep the heating on

    If your home is susceptible to the cold, the best option would be to turn up the heat on your thermostat to keep everything above freezing temperature.

    7. Insulate any exposed pipes

    Any piping on the outside of your home has a much higher chance of freezing. Luckily, there are some inexpensive methods to fix this, such as, heat tape.

    8. Declutter your drains

    A horrendous job to be undertaking in the winter, but we cannot stress enough the importance of proper drainage in your home. Any buildup of water is a terrible thing during the winter months.

    9. Keep a tap dripping if you go abroad

    Keeping water flowing will make it less likely to freeze, but when you aren’t in the house water will stay immobile in the pipes. Keeping a tap dripping when you aren’t in the house can be enough to prevent this.

    10. Turn the water off altogether

    Definitely a last resort, but when the house is vacant you can turn the water off to limit damage. If a pipe bursts, it will only leak water that is currently in the pipe, and not lead to a disaster where a constant supply of water sprays out.
