3 ways of getting water treatment into a system

There are many situations in which you might need to apply water treatment in a domestic property. You might be changing a boiler or tackling limescale and corrosion build up – whatever the problem, there are a few different ways to approach actually getting the required treatment into the central heating system. Knowing about these methods, you’ll be able to choose the most appropriate for each job to keep your day moving along efficiently.

Method 1: The most cost effective approach

By using a 1L bottle, you’re going to get the most for your money. However, depending on the situation, it may be trickier or take longer to dose than other methods we’ll cover in a minute.

In their 1 litre bottle format, liquid chemicals can be carefully poured into empty radiators, tipped into a partially-drained towel rail, added via the empty expansion tank in the loft or added at the boiler filling loop using a dosing vessel before finally filling the system: we’ve seen all kinds of ingenious ways developed over the years by heating engineers to get bottle contents into the system.

Method 2: The quickest approach

If you’re under pressure to get a job finished quickly then an aerosol-type can could be the best option.

This is also an ideal way to add cleaner to dirty systems ahead of the actual cleaning process.

Add Sentinel X400 when you’re in the neighbourhood or when you’re discussing the job with the customer. You can then return any time in the next three weeks to complete the clean: the treatment has already begun to do its job, giving a great clean with minimal disruption to the customer.

This uses a special ‘bag-in-can’ mechanism to inject concentrated liquid treatment into a system quickly and effectively without introducing any air or gas. The big time saver here is that you don’t need to drain or depressurise the system – which would otherwise be time consuming when working under pressure.

There are a few points where this can be dosed into a system. You can apply it to a radiator with an adaptor or you can dose via the filling loop. Dosing with Sentinel Rapid-Dose™ takes roughly 30 seconds, making it quicker in most cases than adding a 1L bottle.

Many central heating filters come with a bleed pin which can also be used as a dosing point for aerosol versions of water treatment chemicals.

Method 3: The space-saving approach

If you struggle for storage space in your van then a gel concentrate, used in conjunction with a suitable skeleton gun, may be your best option.

Thanks to the slimline nozzle, application is fuss-free and easy – no need to grapple with a larger container. This is a huge space saver, allowing you to tackle more jobs before restocking the van – perfect for those with a high volume workload or limited storage space.
