1.0 INTRODUCTION
THIS MANUAL SHOULD BE READ IN CONJUNCTION WITH THE ALPHA INSTALLATION AND
SERVICING MANUAL FOR THE E-Tec 20S, 30S & 35S BOILERS WHICH IS APPENDED TO THIS
MANUAL IN APPENDIX “A” AND SHOULD BE ADHERED TO IN ALL RESPECTS WHERE
APPLICABLE,THE FOLLOWING BOILER REFERENCES SHOULD BE USED:-
THE ALPHA 30S RELATES TO THE WHP030-THE ALPHA 35S RELATES TO THE WHP040
The boiler must only be used in conjunction with flue components supplied by ALPHA unless written
consent to use an alternative is obtained prior to installation from Blades LCS
The boiler and cylinder must be checked and serviced annually in accordance with section 6.0 in
the Alpha Boiler Manual and section 7.0 and relevant items shown in the commissioning and
service check list on pages 21-22 of this manual. Failure to comply with this note may invalidate
the warranty. A service record logbook must be kept on site at all times detailing date of service,
any action undertaken.
The Blade Water Heater has been specifically developed as a compact energy efficient boiler cylinder
module for use where high domestic hot water volumes are required.
The Water Heater can also be configured to supply space heating if required see schematic layout on
page 25???
The frame also contains a single Passive Flue Gas Heat Recovery Devices (PFGHRD) which recovers
thenormallywastedlatentheatwithintheflue exhaustgases.Theseareconnectedtotheboiler via a
purpose made insulated stainless steel manifold with a separate condense drain. The recovered energy
from the Passive Flue Gas Heat Recovery Devices is used to pre-heat the cold feed to the DHW
cylinder this increases the overall system efficiency of this unit to 97%. The PFGHRD can be used
with standard CONCENTRIC ALPHA FLUE SYSTEM see ALPHA manual section for details. The
Water Heater can be supplied in two boiler configurations depending on site requirements, either with the
boiler FRONT facing or SIDE facing, all other featured size, duties etc are exactly the same for both
models
Each Water Heater incorporates a high efficiency condensing fan assisted system boiler. See ALPHA
manual Appendix A for boiler performance data.
The burner is ignited electronically and the heat output is controlled by a modulating fan and gas valve.
Together with a 200 or 300 litre stainless steel domestic hot water storage vessel with all necessary
inter- connecting pipework, hot water circulating pump, plate heat exchanger, internal controls and
wiring terminating at convenient interface points for extension into the building services.
Theequipment is mounted within a rigid powder coated mild steel mobile frame suitable forfree-standing
within the plant room.
Each boiler has a built-in controls system allowing boilers to operate as part of a modular system or
individually dependent on application.The boiler is fitted complete with a DHW time control, switch live
for external CH control and a remote boiler fault indication signal connection.
The units are factory tested prior to dispatch, allowing ease of installation with reduced on-site works
requirement.
The benefit of the Water Heater is that by the incorporation of a high recovery plate heat exchanger with
acylinder destratification pumptherecovery timecan bedramatically reduced . This allows high volumes
of DHW to be delivered from a compact 200 or 300 litre storage cylinders, reducing cylinder heat losses
and increasing the overall energy efficiency of the system.
To increase fault tolerance the cylinder is fitted with a manually operated 3kW immersion heater.
