OSO Delta will be launched in autumn 2015 as the UK's first full range of domestic A rated cylinders under the new European Energy related Products Directive (ERP), which goes live on September 26th 2015.
ERP will energy rate all hot water cylinders from this point from A - G according to standing heat losses. OSO has invested considerably in recent years to develop outstanding new insulation technology to minimise heat loss.
OSO will create a new market for discerning and environmentally conscious customers searching for the most energy efficient products available.
