8CTC Hot Water Storage Tanks
Congratulations on your new product!
You have just purchased a CTC Hot Water Storage Tank, which we hope you will be very pleased with.
CTC’s Hot Water Storage Tanks are coil tanks and volume tanks of 300-750 litres and are designed for almost
all types of energy sources. They are available in several models and sizes, and can also be combined to fit most
heating systems and properties.
All the tanks are well-insulated with polyurethane for the lowest possible energy loss.
CTC Hot Water Storage Tank 1 is a series of coil tanks for efficient DHW heating. DHW heating is via finned copper
coils, which are heated by the radiator water in the tank.
CTC Hot Water Storage Tank 2 is a series of volume tanks that can be connected together to achieve the desired
storage volume.
A hot water storage tank is necessary for wood boilers in order to store energy, since wood boilers often produce
more energy than can be consumed at any given time. The size of the tank depends on the size and type of wood
boiler installed.

1. Important to remember!
Check the following in particular on delivery and installation:
1.1 Transportation
• Transport the CTC Hot Water Storage Tank to the installation site before
removing the packaging. The product must be transported and stored in an
upright position.
• Handle the CTC Hot Water Storage Tank in one of the following ways:
–Forklift
–Lifting eye which is fitted in the sleeve in the middle of the top of the tank.
–Lifting strap around the pallet. NB: Can only be used with the packaging
on. Remember that the product has a high centre of mass and should be
handled with caution.
1.2 Positioning
• Remove the packaging and check before installation that the product has not
been damaged in transit. Report any transport damage to the carrier.
• Place the product on a solid surface, preferably concrete foundation, and
stabilise using the adjusting screws at the bottom of the tank. Models without
adjustment screws can be stabilised with spacers. This must be done before
connecting the hot water storage tank to piping and before it is filled with water.
If the product needs to be placed on a soft carpet, base plates must be
placed under the adjustable feet.
• Remember to leave an open area of at least 1 metre in front of the product for
servicing. Space is also needed around the product for fitting insulation and the
top panel.
• The product must not be placed below floor level.
• Connections that are not being used must be appropriately plugged. During water
filling, condensation may occur on the tank exterior. This may be visible as water on
the floor underneath the tank. This condensation will stop once the tank is heated.
The floor drain must be located in the same area.
1.3 Recycling
• The packaging must be deposited at a recycling station or with the installation
engineer for correct waste management.
• Obsolete products must be disposed of correctly and transported to a waste
station or distributor/retailer offering this service.
Do not discard the product with household waste.
1.4 After commissioning
• The installation engineer advises the property owner on the construction and
servicing of the system.
• The installer completes a checklist and provides contact information – the
customer and installer engineer sign the list, which is kept by the customer.
• Make sure to register for warranty and insurance on the CTC website: www.
