1.0 INTRODUCTION
THIS MANUAL SHOULD BE READ IN CONJUNCTION WITH THE ALPHA INSTALLATION AND SERVICING MANUAL
FOR THE E-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,
For reference the boilers within each TWIN PLUS WATER HEATERS package are identical and the following
references should be used.
TPWH60 Equates to 2No E-Tec 30S Boilers
TPWH80 Equates to 2No E--Tec 40S Boilers
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 Twin Water Heater has been specifically developed as a compact energy efficient boiler cylinder
module for use where high domestic hot water volumes are required together with fast recovery and a high
degree of fault tolerance is required.
The Water Heater can also be configured to supply space heating if required see schematic layout on page 17.
Each boiler module can work independently to supply the cylinder with hot water so if a boiler failure occurs
then the hot water system will still function.
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 frame also contains the appropriate number of Passive Flue Gas Heat Recovery Devices (PFGHRD) which
usesthe normally wasted latent heat within the flue exhaust gases. These are connected tothe boiler via the boiler
flue spigot. 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%. It should be
noted on this boiler the PFGHRD can be used in conjunction with standard ALPHA concentric flue
components.
Each Twin Water Heater contains two standard high efficiency condensing fan assisted system boilers. See
ALPHA manual Appendix A for boiler performance data, together with a 500 litre hot water cylinder
The burner is ignited electronically and the heat output is controlled by a modulating fan and gas valve.
Together with a 500 litre stainless steel domestic hot water storage vessel with all necessary inter- connecting
pipework, hot water circulating pumps, plate heat exchangers, internal controls and wiring terminating at
convenient interface points for extension into the building services.
The equipment is mounted within a rigid powder coated mild steel mobile frames suitable for free-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 exchangers with a
cylinder destratification pump the recovery time can be dramatically reduced . This allows high volumes of DHW
to be delivered from a 500 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.

5.5 DHW CYLINDER THERMOSTAT
User explanation
A cylinder thermostat switches on and off the heat supply from the boiler to the hot-water cylinder. It works by sensing the temperature
of the water inside the cylinder, switching on the water heating when the temperature falls below the thermostat setting, and switching
it off once this set temperature has been reached. The water heating will not work if a time switch or programmer has switched it off.
The cylinder thermostat will have a temperature scale marked on it, and it can be adjusted to the chosen temperature, then left to do
its job. The thermostat must be designed to kill off harmful bacteria in the water. Raising the temperature of the stored hot water
unnecessarily results in wasted energy and increases the risk of scalding.
Dual cylinder thermostats combine both the controller and the limit thermostats into one common unit. If you have a boiler control
thermostat, it should always be set higher than that of the cylinder thermostat. In most boilers, a single boiler thermostat controls the
temperature of water sent to both the cylinder and radiators, although in some there are two separate boiler thermostats.
Important Note
As a safety feature, when first connected the Electronic Dual Cylinder Thermostat will call for heat until the hot water cylinder has
reached 61°C and held that temperature for one hour. During this time there will be a live output to the and therefore to the boiler and
the pump
The Electronic Dual Cylinder Thermostat
The hot water can be stored at any desired temperature between 25°C and 65°C, with the confidence that the weekly automatic one
hour “boost” to above 60°C kills any legionella bacteria, resulting in substantial energy saving.
The LCD display shows the current water temperature and the user defined water temperature, while the red LED indicates that the unit
is calling for heat. The sensitive electronic sensors operate at a far greater accuracy than conventional oil filled mechanical dual
thermostats, and do not need physical contact unlike traditional dual thermostats.
The large dial makes it easy to set the required controller temperature (between 25°C and 65°C). While the second (limit) safety
thermostat is pre-set to 80°C with a concealed manual reset, to comply with building regulations.

Blade 60 & 80 Twin Plus Water Heater Manual July 2020
11
Boiler Setting
To ensure the elimination of Legionella Bacteria in the Hot Water Cylinder, at least once a week the Cylinder should be heated to 61°C.
This is carried out automatically by the Cylinder thermostat. The Boiler Thermostat (output temperature) must therefore be set to
maximum and USER should be made aware that once a week the hot water will be warmer following the automatic “weekly boost”. We
also therefore strongly recommend the use of a thermostatic mixing valve (TMV), these blend hot water with cold water to ensure
constant safe shower and bath outlet temperatures, preventing scalding.
Holiday Switch
This is the black button located under the display. Press and hold the holiday switch for a minimum of 10 seconds until you hear an
audible click, and this switches the cylinder thermostat off completely so there is no water heating and no weekly “boost” heating. This
feature should only be used when the property is vacant for extended periods and there is no requirement for water heating or for the
weekly “boost”. Pressing and holding the holiday switch again (for a minimum of 10 seconds until you hear an audible click) will restart
the cylinder stat, the display will show the cylinder temperature and the weekly “boost” will immediately start and recur every 1-7 days
depending on the user set position at the same time.
Adjusting and Resetting the Cylinder Thermostat
Adjust the dial to show the desired hot water temperature on the display, between 25°C to 65°C. The lower the temperature, the less
chance of scalding and the more energy saving. The Cylinder temperature will be factory set at 61°C. If the system should overheat, the
cause must be determined and resolved by a suitably qualified person. In the event of an overheat, the thermostat cuts out
automatically. THE RESET FOR THE OVERHEAT THERMOSTAT IS LOCATED UNDER THE ADJUSTMENT DIAL.
Adjusting the 1 Hour Boost
The Cylinder thermostat has user defined settings where the duration of the Legionella Override can be adjusted from 1 to 7 days or
completely disabled to operate as a conventional Dual Cylinder Thermostat.
1. To disable/adjust the legionella boost turn the unit off by pressing and holding down the HOLIDAY button until an audible click is heard
and the red LED turns off.
2. Release the button and after approx. 10 seconds press and hold the HOLIDAY button again. After 5 seconds the red LED will light up
and an audible click is heard, keep the HOLIDAY button pressed for a further 5 seconds until the LCD display flashes.
3. Release the button and use the HOLIDAY button to choose between disabling the override (OF) or setting the delay between the
overrides from 1 –7 day
