Can the system run the central heating in a house?
Yes, that is one of the principal applications of the system.
Can the panels face in any direction?
They should preferably face south.
What is DHW?
DHW stands for Domestic Hot Water
What does each panel weigh?
Approximately 8 kg.
How many panels are needed for DHW for a 5-person family?
For a 5-person family, the system normally used is the Eco300 (300 litres) with one solar panel.
What temperature will bath water get up to?
Approximately 55 ºC (the temperature allowed by law).
Can it be adapted to any type of central heating (radiators, convectors or under-floor heating...)?
Yes, preferably convectors, under-floor heating, air convectors or radiators.
Will it give hot water on cloudy days?
Yes, as the fluid passes through the low temperatures inside the panel it receives energy, even on days with no sun and at night, and transmits this same energy to the water.
Does special plumbing have to be installed?
No. Your current plumbing will be compatible.
Do the panels have to be installed on the roof?
Not necessarily. They can also be installed on a terrace, flat roof, façade, on the ground, etc.
What liquid is used in the panels?
For DHW systems use R134a, for central heating and Swimming pool and DHWLV it's the R407c, or other ecological refrigerant..
If there is a leak, can the gas be dangerous?
No. They are ecological, non-toxic gases.
Does the refrigerant have to be regularly re-charged?
No its not.
Are there cylinders from 500 litres?
There are DHW systems up to 500l then there are DHWLV systems with cylinders up to 6000l.
Does the DHW system need a great deal of maintenance?
No, just check the magnesium anode (the protective element for the cylinder) once a year, and change it if necessary.
What distance should the panel be from the tank?
It should not be more than 15 metres higher and/or 30 metres in distance.
How much energy does it use?
That depends on the system in question, but the systems are low in consumption when compared to the thermal power supplied, e.g. the ECO 300I uses 390 W. In an extreme situation where the compressor runs for 1 hour without stopping it will cost (0.039 €/h), with a bi-rate meter you will get a 41% reduction in cost.
For how long will the panels resist corrosion?
The panels are made from anodised aluminium, that is, they have no corrosion problems.
Can the panels be painted?
Yes, preferably in dark colours.
How are the panels fixed?
They must be fixed with the six screws provided for that purpose.
Can it be used to heat swimming pool water?
Yes. That is the situation that will give you the quickest return on your investment.
Do they have a guarantee?
Yes. Panels 5 years and the block 2 years.
