Is Radiator Balancing Necessary for Efficient Home Heating?

The fact is that I can no longer count how many times I have been asked for a quote to replace the boiler with a more powerful one, as the existing one is unable to heat the house. Believe it or not, in most cases, the DIY Gas Safe Engineers* would undertake such a job, replacing an existing boiler with a more powerful one without any further investigation. Obviously, that usually ends with thousands being spent, and the problem still remains unfixed.

Of course, the problem is not always a poorly balanced system. Very often, the cause is a dirty/clogged system that requires cleaning/flushing, an incorrectly sized pump and, in very few cases, an undersized boiler.

But now let’s focus on the topic of this post:

Is Radiator Balancing Necessary for Efficient Home Heating?

Radiator balancing ensures that the amount of hot water flowing through each radiator in a central heating system is evenly distributed. When a central heating system is unbalanced, some radiators may heat up too quickly or not at all, while others may remain lukewarm. This not only reduces the efficiency of the heating system but can also result in higher energy bills. Balancing the radiators ensures that the hot water is distributed evenly throughout the system, allowing each radiator to heat up at the same rate. This can help optimise the heating system’s efficiency and reduce energy consumption, leading to lower energy bills.

I hope that this brief post will help you, at least a little, to understand the various aspects that affect the efficiency of our heating system, and you will be more cautious when choosing a contractor.

Let’s also not forget that not all gas engineers are heating engineers and vice versa!
