The TDCH is a thermo dynamic sytem based on air source heat pump
using ambient room air which is then forced through a heat exchanger
and condenser using refrigerent fluid. This is all contained in a
compact easy to install housing

space for air in and air out
The installation should be carried out as detailed
below:
• Check that there is sufficient space for the
unit see Fig 4
• Check that there is sufficient space to hook up
the pipework and electrics.
• The unit must be transported vertically
• The unit must be installed vertically
• Check that the setting area in strong enough

NOTE
The TDCH works by drawing ambient air in, extracting the heat, and expelling cold air out at the
rear of the unit.
It is best pactice to situate the unit next to an outside wall and and fit ducting to direct the cold
air to the outside of the building.
Hot air drawn in through top of unit and
cold air expelled at rear through wall
ducting

IMPORTANT
The equipment is rated to 6 bar on the cold water feed side and a safety valve is
supplied see Fig 5 and should be installed.
It is recommended that an expansion vessel (tank) is fitted on the cold water outlet side.
The current plumbing regulations should be referred to when fitting the
expansion vessel
17 is located on the rear of the unit see Page 8

NB Resitance refers to Immerser Coil
After the pipework for the tank and the CH coil have been fitted.
Fill the tank by opening the cold water feed at the bottom of the unit See page 8,
allow the tank to fill and monitor the hot water outlet for water returns.
Close the cold water feed and hook the hot water outlet to the hot water system

The unit is fitted with a 2 K watt immerser coil situated at the back of the unit this can be
switched on manually maximum temperature is set at 70 deg C, the switch is on the front
of the cabinet see Fig 7 (resistance switch).
NOTE
To activate the immerser coil both the thermodynamic and the immerser coil switches
must be in the on position

9 Central Heating Booster
The principle is that wet central heating systems use the majority of the fuel when the system
starts up in the morning after the water in the system has cooled down in the circulation pipe
work
The TDCH provides hot water to the CH system at circa 40 deg C constantly or at specified
times.
If a CH system starts up at 6 am the energy required by the boiler to get the system up to
operating temperature is a function of the start and end (operating temperature) temperature
i.e
Without TDCH booster
A Start temperature = 15 deg C
B End temperature = 80 deg C
Energy required= B-A (80-15) = 65 multiplied by the volume of water in the system V
X This equals 65 V calories
With the TDCH booster
A Start temperature = 40 deg C
B End temperature = 80 deg C
Energy required= B-A (80-40) = 40 multiplied by the volume of water in the system V
Y This equals 40 V calories
The energy saving is the difference between X & Y
9.1 Connecting the TDCH booster
After the TDCH water heater is connected to the drawn hot water circuit.
The central heating booster coil is connected to a WET CH system.
Standard or Combi. ( in the case of a combi boiler the drawn hot water should be switched off)
When the booster coil is connected to the CH sytem the TDCH acts like a
indirect unvented cylinder in as much that when the boiler is in operation it will
raise the temperature in the TDCH tank to the boiler operating temperature if the
boiler temperature is above the TDCH temperature, usually 55 deg C
1. Turn off the fuel supply
2. Turn off the electical feed
3. Drain the CH system
4. Connect a 22 mm isolation valve to both the oulet & inlet on the TDCH booster coil
5. Connect the ciculation pump to the oulet on the TDCH booster out let fig 7 on page 22
a. MAKE SURE THE BOOSTER PUMP IS CIRCULTING IN THE SAME
DIRECTION AS THE BOILER PUMP
6. Connect a 22 mm feed fig 7 on page 22 by teeing it into the FLOW side of the CH
system as near as possible to the boiler and the other end onto the isolation valve on
the oulet on the TDCH
Thermo Dynamic water heater & central heating booster
www.elitetdch.com ELITE TDCH Aug 2014v1 Page 23 of 25
7. Connect a 22 mm return fig 7 on page 22 by teeing it into the RETURN side of the CH
system as near as possible to the boiler and the other end onto the isolation valve on
the inlet on the TDCH
8. Make an electrical connection under BS 7671 between the pump and and a 240V 60
Hz electrical connection on a timer
9.2 Commisioning the system
9. Set the timer to on
10. Close the system drain cock
11. Fill the system with water
12. Bleed off any air from the highest radiator.
13. The TDCH system usually takes 8 hours to reach 50 plus deg
14. After the system is at operating temperature
15. Switch on the TDCH circulting pump.
16. The TDCH pump starts pumping hot water into the central heating system.
a. If any problems or leaks are detected .
Switch off the circulating pump close the isolation valves refered to in step 4
above, then rectifying the problem then open the isolaton valves and turn the
circulting pump back on
17. The boiler starts up but uses less fuel to reach operating temperature.
18. When the boiler reaches operating temperature close the TDCH pump manually or by
insertation of a thermastaically controlled switch ( optional)
19. Set the timer to come on
a. 1 hour before the boiler start up time .
b. ½ hour after the boiler start up time.
The hot water setting is 55 Deg C
The temeprature can be raised to 70 Deg C for the elimination of legionella by switching
on the immersor button for 1hour see page13
Recomendation :If the water coming from the hot water outlet is above 55 deg C then
either adjust the TDCH temperature control or the central heating boiler temperature.
If required a zone valve can be installed in the TDCH central heating return line so that it
is timed to close the return feed line after the central heating boiler starts up, it is then
timed to open when the TDCH starts circulating prior to the central heating boiler starting
up, this will ensure that there is no secondary source of energy to raise the water
temperature.
Current building/ hot water regulations should be adhered to at all times
