Common Power Flush questions
Question: By how much can I expect to reduce my annual fuel bill by if I have a power flush carried out?
Answer: Every system is different! For this reason, expected savings will vary dependant upon the severity of sludge build-up in the system. A badly corroded system can often achieve reductions on fuel usage by as much as 30%, sometimes a little more! However, it greatly depends upon individual circumstances.
Question: My radiators are warm at the top, but are hot at the bottom. Will a powerflush fix this?
Answer: From your description, it sounds like you have air trapped in the radiators (which rises to the top). I would suggest that you bleed the radiator first to see if this cures the problem. You dont want to pay for a powerflush if you dont need one!
Question: Are you ‘Gas Safe’ registered?
Answer: This is an important question to ask an engineer before allowing them access to any component on the gas side of your boiler. However, as ‘Powerflush Engineers’, we DO NOT EVER touch the gas side of a boiler (have no need to), as we only work on the water side of a boiler (heat exchangers, water diverter valves and system main pump).
Question: I have oil fired central heating. Are you still able to perform a Powerflush of my system?
Answer: The simple answer is yes! It does not matter whether your central heating system runs on gas or oil, the radiator system works in the same way, irrespective of which type you have.
Question: Most (Not all) of my radiators are hot at the top, but cold at the bottom. Will a powerflush solve this problem.
Answer: It sounds very much as if your system is suffering from corrosion/sludge build-up. Unless you have had a system powerflush carried out in the last few years, I strongly suspect a thorough flush could be exactly what is required.
Question: On your home page you say a superflush will save me up to 50% on my heating bill. What is the difference between a powerflush and a superflush?
Answer: Our Powerflush treatment provides a full central heating system flush cleaning pipework, radiator panels and central heating heat exchanger. Our Superflush does exactly the same, however, it also includes a TRV (thermostatic radiator valve) upgrade and system pre-dose.
Question: How often should my system be powerflushed?
Answer: As a basic rule of sum, we recommend that a system should be flushed every 8-10 years depending on the type of boiler/pump/system and its age, the type and condition of pipework as well as its bore size (15mm or Microbore), as well as local water hardness (Limescale saturates). If your system has its inhibitor regularly added, one can expect even up to 15 years between powerflushes.
Question: Will powerflushing cause leaks?
Answer: The powerflush pumps we use (Kamco) are the very best available. They are highly developed and work on the principle of ‘Water Velocity’ as opposed to ‘Water Pressure’. In actual fact, the pumps operate at a lower ‘Bar’ pressure than is generally found on an average heating system! Therefore, leaks following a powerflush are very rare and would only be expected if an existing fault or failure was present in the system.
Question: Do you provide some sort of guarantee for the work you carry out?
Answer: Yes. After your powerflush has been completed, your engineer will issue you with an official powerflushing certificate. This certificate confirms that the powerflush has been carried out properly and that pH levels within your central heating system conform to industry standards. The certificate will also confirm that an appropriate anti-rust inhibitor has been added. Furthermore, we guarantee that your powerflush has been carried out thoroughly and that your system will not require a re-flush within the next five years, subject to our standard trading terms and conditions.
Question: I am having a new boiler installed, do I need to have my central heating system powerflushed before installation or can I wait until after I have had this done?
Answer: Installing a new boiler without a powerflush is not a good idea. click here to find out why!
