One of the best ways to protect your central heating system is to stop the sludge, rust, and other debris from entering the system in the first place. The best way to do this is by having a filter fitted. Without one, you can drastically shorten the life expectancy of critical components of your heating system, which will cost you more money in the long term.

Here at Complete Gas Heating Services, we can supply and fit a range of top-quality filters, including the award-winning ADEY MagnaClean, Spirotech, and the Worcester Greenstar System.

What makes each of these filters unique, and which one should you choose?

ADEY MagnaClean

The name MagnaClean alludes to the innovative magnetic filter system that ADEY created. Some of the unwanted particles that pass through your system are tiny – microscopic, even. However, while they are small, they are absolutely mighty in terms of the damage they can do to your central heating system. The ADEY MagnaClean filter captures even the tiniest of particles before they stick around and cause problems.


The Spirotech is a reliable filtration system to prevent sludge and other small particles from getting in and making their way around your central heating system.

3 types of spirotech:


Today’s highly efficient heating and cooling systems can only offer optimal performance and safe energy with dirt free water, in untreated systems, dirt can acuminate in multiple places throughout the system, studies and practical experience show that magnetite in particular leads to greatly reduce energy efficiency and their higher energy costs. The benefits of the Spirotrap entail:

  1. Very small particles from .005mm are separated and removed.
  2. Including a magnet for extra protection and highly efficient removal of magnetite.
  3. Dirt can be removed while the system is in use.
  4. No shut off valves.
  5. Maintenance takes a few minutes.


Air removal/deaeration in heating or cooling systems heat is transported from the heating or cooling unit via the systems fluid (mostly water) stacked air in the systems will harm the performance and efficiency of your system as it disturbs the free flow of systems and will encourage rust sludge and micro-organism building in system. The benefits of the Spirovent/deaeration.

  1. Removes all circulating air and microbubbles effectively.
  2. Applicable for high temperature systems configurations.
  3. Removes trapped air when installed at the correct location.
  4. Greatly reduces the need for manual venting.
  5. No unnecessary shutdown.


A good hydraulic balance is highly important in large domestic, light commercial and large commercial system, with separated circuits or several groups and pumps, the effective removal of air and dirt also ensures water heating systems perform at the best, hydraulic balancing and air dirt separation are combined in the Spirocross. The benefits of the Spirocross.

  1. Three functions in a single component.
  2. An optimal hydraulic balance between primary and secondary pumps.
