5.4 Heating /cooling circuit connection
ecoGEO C heat pumps are designed for use in heating systems with low temperature heat radiators (underfloor
heating or fan coil) or medium temperature radiators (convector or low temperature radiators).
For maximum energy efficiency of the heat pump we recommend designing the heating system with a forward
temperature as low as possible (ideally around 30°C), since the increase of the forward temperature causes a
significant reduction of energy efficiency.
Inside the heat pump are included the following components required for the heating/cooling system (see
section 3.4).
• Variable speed and high efficiency pump (energy class A).
• Expansion vessel (12 l).
•
Safety valve (6 bar).
•
Drain valve.
To connect the heating/cooling circuit piping, take into account the note in Figure 5.2 and the following
recommendations.
•
Use the flexible hoses that come with the heat pump to avoid excessive stress in the inlet and outlet
pipes.
• Install shut-off valves on the heating/cooling outlet and inlet circuits. These should be as close to the
heat pump as possible to facilitate future maintenance work on the heat pump.
• Install a particle filter in the heating/cooling inlet circuit.
• Install air vents at all points of the installation where air pockets may form.
NOTE
ecoGEO C heat pumps must not be used in heating systems with high temperature radiators, or in
other applications that require outlet temperatures of above 55ºC; these would cause equipment
malfunction.
Make sure the pipe connections are not subject to stress. This may cause leaks.
The inlet and outlet pipes of the heating/cooling circuit must be insulated to prevent heat loss and
avoid unnecessary risks of freezing the fluid.
DANGER!
Do not install components that may clog the inlet or outlet of the safety valve of the
heating/cooling system. There may be risk of breaking some of its components and causing injury
and damage to property or both.
When installing the heating/cooling circuit, special care must be taken to avoid getting water on the
electrical panel. This could result in personal injury from electrical shock and cause equipment
malfunction or both.
