CYLINDERS AND COMBINATIONS
Albion ECO products are designed for use in systems employing ECO heat sources eg. solar,
geotherm and heat pumps with additional heat provided by fossil fuel i.e. gas, oil, electric input.
The installation must be carried out by a competent installer. In addition to the information
provided within this document all legal requirements and best practices must be adhered to.
Position the unit on a firm base which allows air flow under the concave bottom of the
product. Ensure the structure is capable of supporting the gross weight of the product see product label.
CYLINDERS ONLY
ECO cylinders are open vented storage vessels designed for use in static open vented
systems. The maximum working head is indicated on the product label. Ensure this cylinder
is suitable for your installation before proceeding. Connect ‘C’ cold feed to the cold feed
cistern via an isolation valve and fit a drain cock at the lowest point of this pipe adjacent
to the cylinder. Connect ‘A’ hot water draw off and open vent connection to hot outlets
and provide an open vent to the cold feed cistern. The minimum size for an open vent is
22mm. The vent must rise continually and be permanently open with no obstructions. Try
to avoid a wholly vertical vent pipe.
COMBINATION UNIT ONLY
ECO Combination units are open vented vessels with an integral cold feed cistern. The cold
feed and open vent pipes are also integral. Cold entry to the unit is via a ball valve and a
float (not provided) and an overflow warning pipe must be installed. Connection ‘L’
female BSP is a drain point. The hot water draw off ‘A’ connects directly to the hot
water outlets.
BOTH CYLINDERS AND COMBINATION UNITS
ECO Element
Connections ‘D’ and ‘E’ are the ECO element providing heat input into the base of the
unit. Connections are 22mm compression. ECO elements must be fully pumped and are
suitable for open and sealed systems up to a maximum pressure of 7.0 bar pressure. If
the pipework does not rise from the ECO element, ensure adequate air release is
provided. Connect flow to connection ‘E’. Thermostatic control of the ECO system is via
a probe thermostat (not supplied) and
ECO control system. Connection ‘F’ provides for this facility. Ensure the setting of the
thermostat will not allow the water temperature to exceed 65

Please note that the Centurion ECO cylinder has a 28mm diameter spirally wound coil
suitable for both gravity and pumped systems, whereas Superduty ECO HE cylinders are
fitted with the Superduty Multicoil which is suitable for fully pumped systems only.
Both types of coil are suitable for open vented or sealed systems up to a maximum
pressure of 3.5 bar. Flow share and priority heat plans are acceptable. The primary
connections are 1” male BSP fitted with Albitec adaptors allowing easy connection to
22mm or 28mm pipework. Where primary pipework does not continually rise, provide
an air release point to connection ‘J’. Either ‘H’ or ‘J’ may be used as flow or return.
Provide thermostatic control of hot water via a strap-on thermostat (not supplied)
positioned halfway between ‘H’ and ‘J’. Set thermostat to ensure water does not exceed

Connection ‘G’ provides for an indication of the stored hot water temperature
in the upper part of the cylinder. Clear Skies approvals indicate the type of thermometer
to be used.
IMMERSION HEATER ‘K’
” BSP connection is provided for the installation of an immersion heater. This

facility is designed as a back-up heat source should there be a boiler failure.
OPERATION
The operation of the Albion ECO unit is simple. Cold water in the cylinder is pre-heated
by the ECO source. The heat rises to the upper area. Should the water in the upper 70%
of the unit not achieve the desired temperature, this shortfall will be provided by the
fossil fuel coil or immersion heater as programmed. As hot water is used, pre-heated ECO
water from the lower 30% of the cylinder rises and new cold water enters the unit ready
for ECO pre-heating. As further hot water is used, the cycle continually repeats itself.
