Rocky Hot Water Heat Pump – Save Up to 75% on Heating Your Water!
The Rocky hot water cylinder is powered by a heat pump which is integral to the unit and is
located on top of the cylinder.
It works up to 30% more efficiently than Solar powered hot water panels and is significantly
cheaper to purchase and install. In the process of heating water, it will de-humidify your
bathroom, or kitchen.
The exhaust air which has a temperature of about 10 deg can be used to keep a pantry cool if
the distance is not too great from the cylinder, otherwise it should be exhausted to the outside.
The Cylinder is available in sizes from 80L, 150L, 190L, 260L and 300L.
Key Advantages
•On average its performance is up to 30% better than solar, with significantly reduced
installation and capital cost.
•The co efficiency of performance is 4:1 - this means that for every 1Kw of electricity input,
it gives 4Kw output.
•When you are using the ambient air from a bathroom or kitchen, you are also
de-humidifying the air from those rooms.
•The Exhaust air that is normally discarded, can provide cooling to a room.
•Stainless steel tank.
•18 month warranty.
How it works
The heat pump uses the ambient air from the building. This air can be taken from a bathroom,
kitchen or from the ceiling of a stairwell. A 150mm duct is used to bring the air to the cylinder
and likewise to exhaust the air away from the cylinder.
When the heat pump is switched on, it extracts air from the rooms mentioned above and further
compresses it to heat the water to 55deg by means of an internal coil down through the cylinder.
The exhaust air which is now approximately 10 degrees needs to be discarded; this air can be
exhausted through the roof, the wall, or can be directed to another room for cooling.

C. Installation instruction
How it’s works
The heat pump uses ambient air temperature from the building and this can be taken from a
bathroom or kitchen etc.
The pump takes the heat from the air, compresses it to a higher temperature and transfers
this heat directly into the water.
The exhaust air which is now approximately 10 degrees needs to be discarded; this air can
be exhausted through the roof or wall of the dwelling, or can provide cooling for another room
(e.g. pantry).
Installation notes:
1. The cylinder can be installed anywhere within the building provided the intake and exhaust
air ducts can be installed without having to run the pipes too far or having to fit too many
bends on the run.
2. The heat pump is best located with the air intake coming from an area with excess heat e.g.
a bathroom or kitchen (minimum of 120 cubic meters).
3. The air inlet and outlet are at the top of the cylinder.
4. The cylinder should not be placed in the open air.
5. Avoid debris entering the vents.
6. The air inlet and outlet ducts are 150mm dia.

C. Installation instruction
(Fig. 3)
Option 1: Exhaust air to outside through the roof, ambient air from another room.
Option 2: Exhaust air to outside through the wall, ambient air from another room.
9. Fig 3 shows the inlet air duct taking air from another room and the exhaust air being dumped
outside either through the roof or external wall.
10. Because the air outlet comes with cooling air, the surface of the pipe may have condensation
water, it’s necessary to insulate the indoor outlet pipe to prevent water leakage.
11. Heat pump water heater unit must be placed upright, and installed on a solid surface that can
be able to withstand a weight of over 700kgs. Supporting surface should be level.
12. In operation the unit should be located in a well-ventilated location and with nothing blocking
the air vent, so that the machine can be able to inhale and exhaust enough air, to achieve hot
water supply function.
13. The appliance can work without an air duct.
14. There should be a drain around the system unit for drainage. And the surrounding area of
the tank should have enough space for maintenance. Because the top cover can be opened,
at the top side of the unit, there should be at least 800mm space for maintenance at the top.
15. Nearby the system unit, there should be a reserved water supply pipe and hot water pipe
interface equipped with valves, the water inlet pipe should have a filter (for cleaning).
16. For waterway connection of this integrated unit, please refer to the “Waterway installation
diagram” (Fig.4 pg7).
17. On the system unit, there should be a three-port valve, a safety valve and a filter installed.
Connect them to the water inlet and outlet of the unit.

6
C. Installation instruction
18. The working pressure of this water heater tank must be ≤7 bar. The water inlet must be
connected to the safety valve with an operating pressure of 7 bar.
19. Water inlet pressure should be greater than 1 bar, if the pressure is lower than this connect
the pressure pump on inlet pipe to get a higher water flow.
20. Ensure the water tank is fully filled with water before turning on the system: First, open
the valve on the water supply inlet, then switch on either valve of the water outlet, and then
you can pour water to the tank until the water overflow the water outlet valve. After which you
can turn off the water outlet valve and check for leaks. (Make sure there is no water leaking).
21. If the system is switched off for a long period through the winter, the water tank should be
drained to prevent frost damage.
22. If connecting to a pressurised system or mains water always use a pressure vessel for
expansion.
23. If the water heater is equipped with an optional auxiliary heating coil at the bottom of the tank.
This coil can be connected to solar panels, solid fuel back boilers, oil or gas boilers. This
option is generally only used as a backup system.
24. If the water heater is equipped with an optional coil at the top of the tank, this coil can be
used for heating a small underfloor area, a few radiators or a couple of towel rails which would
avoid having to turn on the main system in the Summer time to heat the bathroom.
25. There should always be enough space around the system for maintenance.

2 Before installation, it’s better to reserve a water supply pipe interface, hot water outlet pipe
interface and drainage pipe interface. Among them, the water supply pipe and hot water outlet
pipe should be used in line with standards for drinking water pipes. (E.g. PPR pipe or stainless
steel pipe, etc.), can’t use iron pipe or the rubber hose with odor for installation.
3 If using in a place below 0 degrees, make sure to insulate the water pipes to prevent freezing.
4 Air inlet /outlet can connect Φ150mm vent tube, but pipes shouldn’t be too long.
