Central Heating Inhibitor: Why Should I Use A Central Heating Inhibitor?

Central Heating Inhibitor: Why Should I Use A Central Heating Inhibitor?

Let me start off by briefly explaining what a central heating inhibitor actually is..

A central heating inhibitor provides protection for domestic central heating systems against limescale and corrosion formation.

Curious customers sometimes ask why we add inhibitor to their brand new central heating systems which we’ve just installed. There are no guarantees to how long your new central heating system will actually last but we always recommend playing the odds and doing everything which is likely to work in your favour. Using a good quality central heating inhibitor, along with installing a programmable room stat, a magnetic filter and a scale inhibitor, will only help to extend the life of your system.

We don’t actually ask our customers if they would like us to use an inhibitor. It’s always been standard practice for us and for most good plumbers out there.

The different boiler manufacturers use different metals in their boilers so a central heating inhibitor helps to keep your system clean which in turn means that it’s less likely that your boiler will break down. This can be seen as a potential cost saving as you won’t have to spend money on boiler spare parts and labour.

Central heating inhibitor is suitable for hard, soft and softened water and help to prevent cold spots in radiators.

Other benefits include improved energy consumption efficiency which can help lead to cheaper gas and electricity bills. An efficient central heating system will use less power.

How Do You Add Inhibitor To My Central Heating System?

The most common way of adding the inhibitor into the central heating system is simply by pouring it into the radiator using a funnel. We normally pour it in when the system is empty. When the system is filled the inhibitor will spread evenly throughout the pipework.

We normally pour the central heating inhibitor directly into the radiator.

How Much Central Heating Inhibitor Do You Use?

Most domestic properties will need at least 1 litre of central heating inhibitor. The general rule of thumb is 1 litre to 8 radiators.

Which Central Heating Inhibitor Shall I Buy?

The top rated central heating inhibitors on the market today are Sentinal X100 Inhibitor and Fernox Protector F1.

We normally go with Sentinal but Fernox is just as good.
