which is extremely corrosion resistant, making it the perfect
choice for the Greenstore unvented and solar compatible
unvented cylinder series.
There are two different coil output sizes within the

What is ErP?
The ErP Directive, which is a new regulation
set by the European Union, is designed to drive
improvements in the efficiency and performance of
heating and hot water products. Its purpose is to
ensure that end users are aware of the level of
energy efficiency inherent within their appliances.
As such, the Directive will help improve the overall
efficiency of the housing stock, while enabling
homeowners to reduce their energy bills. The ErP
regulations cover boilers, combination boilers,
heat pumps and other heating appliances up
to 400kW.
What is Energy Labelling?
The Energy Labelling involves a label which we are
familiar with today on washing machines and

Please note, some systems may require a check valve to be installed depending on the position of the boiler to the cylinder – in order to prevent
gravitational circulation.
The Worcester Greenstore unvented cylinder is designed to be installed with any gas- or oil-fired boiler. It features 1 coil
and a G3 compliant Inlet Control Group.
The Worcester Greenstore solar compatible unvented cylinder is designed to be installed in conjunction with the
Greenskies solar package. The lower coil is connected to the Greenskies solar system and controls as per the Greenskies
instructions. The solar sensor supplied as part of the Greenskies collectors inserts into the lowest pocket. The upper coil is
connected to the secondary appliance, which will heat the cylinder if insufficient energy is available from the lower coil.
Either of the coil connections may be utilised as the flow or return on a Greenstore cylinder.
