TECHNICAL MANUAL
HEAT PUMP TANKS

Before the installation and use of an ENVIROENERGY SOLUTIONS Solar Tank, Buffer Tank, Heat Pump
Tank or electric Calorifier please read and observe carefully all the instructions concerning the
installation, maintenance and use of the product, in this manual. The non-observance of these
instructions may result in the cancelation of the warranty.
GENERAL SAFETY INSTRUCTIONS
•Attention when lifting the tank and always take precautions in order to avoid possible accidents,
injuries and other hazards. During transportation and handling of the tank avoid abrupt
movements as they may result in fall and damaging of the Tanks. To avoid damaging the tank, do
not remove the packaging, until it reaches the installation location.
•All installations and maintenance must be performed by qualified and certified professionals,
following all relevant local norms and regulations (1), industry codes, and according to the
manufacturer’s instructions.
•Always make sure that the installation site, especially on roof tops, is adapted to the weight and
mechanical restraints of Tank when full (and eventually a 30% margin), as well as any further
weight expected (snow, rain, etc...). ENVIROENERGY SOLUTIONS declines any responsibility that
may arise from an improper or defective installation or from incorrect manipulation of the system
or accessories composing it.
•Always make sure there is enough space around the Tank for maintenance purposes, as well as
for the electric cabling and plumbing. It is recommended to agree with the client for the location
of the installation and the routing of pipes and cabling.
•In case the Tank is placed Outdoors in regions with heavy snow fall or strong winds, it may be
necessary to further anchor the system to the point of installation. In this case it is up to the
installer along with the client to determine the best and safe way to install the Tank. Additional
fixing points or equipment may be required.
•Never fill the closed circuit or connect the electric element with an empty tank. The tank must
always be filled with water during these operations due to a risk of severe damage to the Tank.
•Before starting the installation or maintenance, the main power supply to the system must always
be turned OFF, and the Heat Exchangersin case of Removable Heat Exchangers, must be removed.
•Improper installation and works can contaminate the potable water. Install the Tank hygienically
and rinse the Tanks and piping thoroughly with potable water
•Install and use potable water pipes according to current standards and local norms and
regulations.
•The use of plastic, PVC or polypropylene piping is not recommended, especially for the closed
circuit, due to the very high temperatures developed by the installations. In any case, make sure
that all the piping used in contact or close to the systems outlets can withstand minimum
temperatures of 100ºC, or 180ºC if in contact with the primary (closed) circuit.
ENVIROENERGY SOLUTIONS recommends the use of copper or stainless-steel piping for safer and
higher performance.
•It is recommended that the Tanks be maintained by a professional, checked and cleaned at least
every 2 years. In locations with hard or dirty water an annual maintenance and cleaning is
recommended. Please refer to the “Maintenance and Servicing” section of this manual.
•A pressure release and safety valve ismandatory on the cold-water inlet of the tank and a pressure
reducing valve is mandatory in case the pressure of the water coming into the tank is above 3 bar.
•A mixing valve is compulsory on the hot water outlet in order to limit risks of burning and
Expansion Vessels are recommended in order to limit pressures in the Tank and unnecessary loss
of Water.

GENERAL INSTALLATION INSTRUCTIONS
•Always make sure that all the piping of the primary and secondary circuits, going to and coming from
the Tank, are very well insulated, even in hot climate regions and treated for UV radiation.
•Avoid leaving the Tanks for long periods without using hot water (holidays, prolonged absences, etc...)
due to risks of overheating, or make sure all the heating sources (solar panels, heat pumps, electric
elements, burners, etc…) are turned off or inactive during this period.
•In case of use of Electric Heating Elements, the Tanks must be grounded
•It is recommended that the installation location be equipped with functional drainage on the floor
•Hydraulic connections to the tank must be such as to limit the phenomenon of electrolysis
•Every service and maintenance should be recorded in the maintenance book. This record is a key
element to the validity of the warranty and should be made available on request
•Under no circumstances should any welding or repairing be made on the tank’s metal structure. Risk
of deterioration or destruction of the tank and annulation of the warranty.
•The electric heating element is not part of the system but an additional part and it should be installed
by a certified electrician. The electric back-up should be used only in case the water temperature in
the Tank is under 50°C. The constant and unreasonable use of the electric back-up may cause damage
to the tank and cause annulation of the warranty.
•The quality of the water entering the Tanks should be within potable standards and in any case be
within the values of the table below. If the quality of the water does not correspond to these values
then special filters and water softeners may need to be installed to satisfy these conditions, or the
warranty will not be valid.

WARNING:
IF THE HOT WATER SYSTEM IS NOT USED FOR TWO WEEKS OR MORE, A QUANTITY OF HIGHLY
FLAMMABLE HYDROGEN GAS MAY BE ACCUMULATED IN THE WATER HEATER. TO DISSIPATE THIS GAS
SAFELY, IT IS RECOMMENDED THAT A HOT TAP BE TURNED ON FOR SEVERAL MINUTES UNTIL
DISCHARGE OF GAS CEASES. USE A SINK, BASIN, OR BATH OUTLET, BUT NOT A DISHWASHER, CLOTHES
WASHER OR OTHER APPLIANCE. DURING THE PROCEDURE THERE MUST BE NO SMOKING, OPEN FLAME
OR ANY ELECTRICAL APPLIANCE OPERATING NEARBY. IF HYDROGEN IS DISCHARGED THROUGH THE TAP,
IT WILL PROBABLY MAKE AN UNUSUAL SOUND AS WITH AIR ESCAPING.
•The safety of the Tanks and validity of the warranty are conditioned by the use of genuine
ENVIROENERGY SOLUTIONS spare parts and accessories. Please only use genuine ENVIROENERGY
spare parts and accessories from your nearest ENVIROENERGY SOLUTIONS dealer or contact the
manufacturer.
ENVIROENERGY SOLUTIONS declines any responsibility that may arise from the non-observance of the
installation, maintenance and use instructions herein, non-observance of relevant local norms,
regulations and industry codes, improper or defective installation, or incorrect manipulation of the

MAINTENANCE AND TROUBLESHOOTING
A. MAINTENANCE AND SERVICING OF THE SYSTEM
1. General maintenance
In order to ensure the constant well-functioning of the Tanks, they must be reviewed and maintained
periodically (see warranty sheet) and the warranty sheet accompanying must be completed accordingly
by the installer.
All installations and maintenance must be performed by qualified and certified professionals, following all
relevant local norms and regulations (1), industry codes, and according to the manufacturer’s instructions.
Before starting any maintenance work, the main power supply to the system must always be turned OFF,
and the Heat Exchangers in case of Removable Heat Exchangers, must be removed.
Revisions consists of:
➢The optical and physical inspection of the tightness of all joints and connections (hydraulic and
electrical), verification that all safety valves, pressure reducing valves and mixing valves are
working properly (safety valves on primary and secondary circuit), that the insulation of all the
pipes is in good condition.
➢Making sure that scale and salts have not accumulated in the valves or in the Tank. Poor water
quality at the water can result in scale formation and may block the safety valves and Tank outlets
leaving the tank unprotected against very high temperatures above 90°C and high pressure
(greater than 10 bars).
➢Making sure the electrical heating elements and thermostats are working properly and do not
have scale or salts accumulation.
➢Cleaning of the Tanks and removal of scale or deposits inside the Tanks, on the Heat Exchangers
and on the electric elements, valves, etc…
➢Making sure that the Heat exchanger is in good conditions and perfect working order
➢The anode (magnesium rod) must be checked every year and replaced if it has been worn-out or
reduced to 50% of its initial size or weight or if it has been covered by the accumulation of salts.
➢Verifying that the weight of the thermal fluid in the primary circuit is adapted to local climatic
conditions. The thermal fluid must in any case be changed at least every 3 years as it loses its
properties through time.
➢Verifying that the water quality entering the Tank is within standards as per the requirements in
the table in the General Installation Instructions in this manual and the eventual filters and water
softeners are in proper working order.
Attention: do not use any detergents, acids or any other corrosive products that may damage the enamel
lining of the Tanks.

When Removing the Stainless Steel DHW Coil, it is Imperative to follow the order 1 to 7 as per the pictures below,
and reverse order when re-installing it.
Pic. 1
2. Replacing the sacrificial anodes (magnesium rods)
For optimal protection of the system against electrolysis, all ENVIROENERGY SOLUTIONS tanks include
magnesium rods (sacrificial anodes) which must be checked and replaced if necessary, at least every year
depending on the quality of the water. The size of the anode varies depending on local norms and
requirements. For replacing the anode, proceed as follows:
•Shut down the main power supply
•Remove the safety valves or expansion vessel.
•Empty the tank.
•Remove the protective cover of the flange and Heat exchanger.
•Pull out the thermostat with caution.
•Remove the flange and unscrew the anode. Screw-on a new anode and following the same procedure
backwards prepare and set the system back to work.

Coil is unscrewed.

B. TROUBLESHOOTING
In case the Solar System does not produce enough hot water, please verify the following:
1. That all hydraulic connections of the system are water tight and there are no leaks.
2. That there are no leaks on the taps or on the piping of the building
3. That the heating sources are working properly.
4. If the level of the thermal fluid in the closed circuit is not too low. Set to level filling with thermal
fluid mixture through the fluid inlet where the safety valve or expansion vessel is placed.
5. That the pipes connecting the heating source to the tank are not bent twisted nor have any angles.
6. That there is no air trapped in the closed circuit of the system.
7. That the supply of cold and hot water is connected.
8. That the temperature set on the mixing valve is not too low (below 50ºC depending on local
regulations)
9. If the electric back-up is working. In case it is not working please check the following:
•That the main power supply is ON
•That the thermostat is not set too low
•That the back-up element is not on security mode. The security button must be pushed-in
•That the thermostat and back-up element are not damaged
•That the back-up element wiring is properly connected and to the relevant terminals
