Note that the cartridge needs to be installed simply in contact with the heating water.  It does NOT require electricity or connection to anything else except to hold it in place physically.

Technical requirements for the installation of a cartridge:

  1. The cartridge must be placed in contact with the circulating heating water of the heating system.
  2. Ideally the cartridge should be in the ‘return’ part of the system where the water is not turbulent. However it can be placed almost anywhere, such as a dead end section of pipe, as long as it is in contact with the water.  It can also be placed in a ‘u-tube’ side portion of the system away from, but connected to, the main flow.
  3. There is no need for electricity, the cartridge does not use chemicals and it does not use magnetism. The cartridge simply needs to be in contact with the circulating water.
  4. The cartridge must not be placed where it may form a blockage or significant obstruction in the main flow pipe.
  5. The cartridge needs to be restrained from moving in the heating system. There is a wire to help hold it in place, but where there may be strong chemicals in the water it is advisable to have it placed so it is restrained and cannot move.
  6. The cartridge is 205 mm long and has a diameter of 25 mm.
  7. The cartridge needs to be placed where air pockets will not form.


Quantifying Energy Savings:

  1. A minimum of a year’s history of meter readings is needed to form a baseline.
  2. The more detail that is available from the meter readings the better. We recommend that you use daily totals, but the data needs to be on at least a monthly for the history using real readings, not estimates.
  3. The analysis of savings uses degree days data and kWh readings from your site.
