Low energy ventilation less than a penny

Less than a penny a day to run

We are experts in balancing energy efficiency with airflow performance - we've got fans that cost the equivalent of two cans of baked beans to run for the entire year!!!

Utilising low energy motors, our products offer excellent energy performances and, for new build, contribute directly to reducing Dwelling Emission Rates in SAP.  For existing homes and refurbishment projects, our intermittent and continuous extract fans use as little as 1 watt in operation! 

We've never 'bean' cheaper...

We are always asked, "how much does a fan cost to run per year?" or, "how much does an MVHR unit or system cost to run per year?"
