The Importance of 22mm Pipework in a Gravity Fed Central Heating System

When it comes to a gravity fed central heating system, utilizing the correct size of pipework is integral to its efficiency and performance. 22mm pipes are one of the most popular sizes for these systems - but why? In this article we will explore why using 22mm pipe in your gravity fed central heating system can make all the difference.


Optimal flow rates can be achieved with the use of 22mm pipework. Gravity fed central heating systems rely on gravity to circulate hot water through pipes, and if these pipelines have a larger diameter it enables for smoother flow. 22mm pipework produces an ideal balance between having enough width for optimal performance, whilst also being affordable and effortless to install.



22mm pipework serves an essential purpose in mitigating heat loss. The bigger the diameter of a pipe, the more room there is for heat to slip away. 22mm pipes are ideal because they provide both a sizable surface area and exceptional flow rates, controlling temperatures while still maintaining strong water pressure output.


22mm pipework is essential for its ability to reduce pressure drop, which occurs as water moves through pipes due to friction. The greater the diameter of the pipe, the less pressure reduction will be experienced. 22mm pipework strikes an ideal balance between reducing pressure and providing optimal flow rates that cannot be achieved with other sizes or types of piping.


In conclusion, 22mm pipework is important in a gravity fed central heating system because it allows for optimal flow rates, minimizes heat loss, and reduces pressure drop. Using the right size of pipework is crucial for the overall performance and efficiency of your central heating system, and 22mm is a great choice for gravity fed systems, if in doubt consult your local plumber in Stoke for more advice.
