We do not ask you to accept our credentials on trust. We are pleased to prove our systems by test.

The test procedure is as follows: - First, we survey your site(s) and then we issue you with a forecast/guarantee of the percentage savings we expect to achieve together with a quotation. Subject to your approval we then install our system and run it on a 28-day, alternate DAY-ON/DAY-OFF test. On the DAYS-ON the heating runs under the control of our system and on the DAYS-OFF it runs as it was configured before our system was installed. The monitors measure the firing time and therefore the fuel used.

If, at the end of the test, the system saves at least the amount of fuel we forecast and guaranteed then we expect you to purchase the system.

There is no risk to your heating system during the test as at any time our system can be switched into BYPASS mode, which completely isolates it from the heating system, which then reverts to its previous controls.

The DAY-ON/DAY-OFF test is now acknowledged to be the best test procedure. It eliminates fluctuations caused by variations in the settings, use or demand and compensates for variations in temperature over the test period. Any changes in settings during the test will affect equally both the DAY-ON and the DAY-OFF.
