    How To Add Inhibitor To A Pressurised Heating System

    Thu 24th Jul 2014 - 6:40am DIY Troubleshooting How To Add Inhibitor To A Pressurised Heating System


    Benjamin Clarke

    This article will look at how to add inhibitor directly into a radiator via a pressure sprayer.

    It’s common to use this method if you have a pressurised heating system and it’s also one of the more complex ways of adding inhibitor to your system. For this reason, we recommend that you tackle this job only if you have done some plumbing before and if you have fairly extensive knowledge of your system.

    Before starting, remember to turn off your heating system, making sure the boiler is off and that it’s completely electrically isolated.

    Firstly, turn the radiator you’ve chosen to add the inhibitor into off at both ends. Then use a standard radiator bleed key to open up the air valve and dissipate any pressure in the radiator. Use a towel to catch any drips or spillages.

    Take a pair of adjustable spanners and remove the nut that houses the air bleed valve. If possible, be as quick as you can when removing the nut and replacing it with your adapter valves. This will avoid any water coming out and making a mess.

    Attach your hose to the adapter, tighten it up and ensure your hose is firmly attached to your pressure sprayer. Pour your inhibitor into the pressure sprayer and open up one of the radiator valves. Start methodically pumping the pressure sprayer so that the inhibitor flows into the radiator and continue to pump a little air into the rad after all the inhibitor has gone into the system. Turn off the valve you previously opened and release the pressure valve on the pressure sprayer until all the air has escaped.

    Remove your hose from the valve at the side of the radiator, unscrew and remove the valve and replace it with the bung that houses the air bleed. As before, do this as quickly as you can to avoid any water coming out. Again, use your radiator key to shut the air bleed valve and open up both of the radiator valves. Open up the air bleed valve again to allow the cushion of air you pumped in to escape, and have your towel close at hand to catch any water.

    At this point you can turn your heating system back on and release more air via the air bleed if necessary. If you have a pressurised system, set the pressure to where you think it should be. If you have a feed and expansion system, it’s likely that you don’t need to do anymore, although you may wish to take a quick look in your loft just to double check everything is ok.

    Energy efficient legacy of the Glasgow Commonwealth Games 2014

    Tue 22nd Jul 2014 - 10:43am Energy and Heating Energy efficient legacy of the Glasgow Commonwealth Games 2014


    Benjamin Clarke

    With the Commonwealth Games 2014 starting tomorrow (23rd July) in our own back yard of Glasgow, we’ve found ourselves very interested in the athletes village and how the houses have been constructed.

    The homes, located in Glasgow’s East End, will house around 6500 athletes for the duration of the games after which, 300 will be sold to private owners, 400 will be for social housing and there will also be a 120-bed care home.

    What interests us most is the fact that these homes will be incredibly green and carbon free and will be heated by a very powerful community heating system, known as ‘district heating.’

    District heating works by having a heat generating plant in a certain location that can then be distributed out to homes in a residential area in a cost-effective, clean and efficient manner. In the case of the Athletes Village, the heat and power will come from a 70,000 litre thermal store, and then will be fed to the houses via 28km of underground piping on a flow and return system.

    What this means for householders is they will have hot water whenever they like without the need for a boiler, as well as a reliable heating source. The water will be on a continuous loop between the thermal supply store and the residential area, where the water will enter the system, be heated in a heat exchanger and then the hot water will be distributed around the home.

    Throw into the mix that these homes have solar panels on their roofs, the savings that householders can expect to make can be anywhere up to as much as 30% when compared with the standard individual heating systems.

    This environmentally-friendly way of providing heat and power is of great interest to us and we’re proud that it’s been happening in Glasgow. We expect more of these district heating systems to be rolled out around the UK in the coming years.

    If you’re interested in energy efficiency and saving money on your heating bills, but are not part of a district heating system, then take a look at our low water content Convector Radiator Range. The main benefits of the radiators is they have huge heat outputs and a stylish design but can run effectively on low temperature heating systems with ground source heat pumps. They use a low amount of water, but can have a very quick impact on the temperature of a room, making them a very efficient and low-cost way of heating your home.

    We wish all the athletes the very best of luck and expect them to get a very warm Glasgow welcome. Here’s hoping for a high-quality, action-packed and energy efficient Commonwealth Games 2014!
