Return on Investment

Home / Return on Investment

How long will it be before Irus has paid for itself?

From the information we have accumulated over time, the majority of projects where Irus has been installed have ‘washed their faces’ over a 3-5 year period.

Every project is different and the Return on Investment is dependent on contributory factors specific to the site, that will affect the potential savings;

• What was the original heating source?
• What was the previous heating control?
• Has the building’s infrastructure been changed with regard to insulation or room configuration?
• Is water heating part of the calculation?
• What is the geographical location of the property?
• What are the time, Setback and Boost temperature parameters?

For the purposes of demonstrating the ROI achieved when installing our products, we use average figures for as many installations as we have access to data from.

It is understandable that our clients consider their data  to be commercially sensitive and do not wish for it to be in the public domain. Therefore, we have taken data and, with permission from a number of organisations, have made it anonymous. All information is accurate as supplied to us.

The information below illustrates a project where we have been able to compare two blocks of a similar size; A.Block – with existing controls; and B.Block controlled by Irus.

The study took place over 5 heating seasons. The graph shows the energy costs over each season and the energy savings, both of which remain relatively constant.

The red line represents the initial system and installation costs with the savings subtracted at the end of each season.

This particular project did not include provision for water heating, PIR detection or window-open technology. The second graph includes a conservative estimate to show further savings if these were to be included.

In this instance ROI occurs during the final heating season.
So, payback is within 5 years.
