Low Profile solar water heaters
A low frame with the same collector area: the cylinder sits 130 cm above the roof surface. For roofs with low parapets and a discreet installation.
- Cylinder at 130cmAbove the roof, for low parapets.
- Less wind loadAnd less visible from the street.
- Selective collectorFull-plate aluminium-titanium absorber, copper risers.
- Closed circuitWith antifreeze, down to −47°C.
- Sun and electricityA 3.5kw element as a second source.
- Easy accessFor servicing, and better compatibility with PV panels.
Same output, lower height.
The Mastersol LP (Low Profile) is a closed-circuit solar water heater on a low frame. The cylinder sits 130 cm above the roof surface, so the system suits roofs with low parapets, is less visible from the street and takes less wind load.
The collector and the jacket are filled with antifreeze, which carries the sun's heat to your hot water, so the system withstands frost down to −47°C. The tank is made of 2.5mm European steel, with Bayer Double Duro Glass enamel, a magnesium anode and 6cm of polyurethane insulation.
The collector has a full-plate selective aluminium-titanium absorber, copper risers and 3.2mm tempered safety glass that stands up to hail and heavy rain.
It is dual energy: the sun heats the water and, when needed, the 3.5kw electric element.
Mastersol solar water heaters carry an A+ energy label and are CE and Solar Keymark certified.
What makes the difference
- Low frameThe collector sits low and the cylinder reaches 130 cm above the roof surface. The system hides behind low parapets and suits places where height, wind or the look of the building call for a discreet installation.
- Double Duro Glass tank2.5mm European steel with Bayer Double Duro Glass enamel fired at 830°C and 6cm of polyurethane insulation. A magnesium anode against corrosion and a 3.5kw electric element.
- Solar Keymark certifiedThe collector carries a Solar Keymark plate with a serial number. The selective aluminium-titanium absorber covers the whole surface, on Ø22 & Ø8 copper risers, and the 3.2mm tempered glass stands up to hail and heavy rain.
- One-piece aluminium frameA one-piece aluminium frame with a 1.25mm profile, a 0.5mm galvanised steel back and double 4cm mineral wool insulation. 100% neutral silicone.
- Closed circuit with antifreezeThe collector and the jacket are filled with antifreeze, so the system withstands frost down to −47°C. On top of the tank are the fill and vent points of the circuit and the seat of its safety valve (1.5-3 bar).
- Made in GreeceMastersol solar water heaters are made in Greece. The heavy-duty brass connections are marked on the tank: hot water outlet and the connection to the collectors.

Questions
Which size do I need?
Mastersol sizes its systems for a normal use of 40 litres of hot water at 40°C per person. As a guide: 1 person, 100 litres with 1.5 m² anywhere in Greece. 2 people, 120 litres with 2.0 m² (1.5 m² is enough in southern Greece). 3 people, 120 litres with 2.0 m², or 160 litres with 2.0 m² in northern Greece. 4 people, 160 litres with 2.5 m² (2.0 m² in the south). 5 people, 200 litres with 3 m², or 4 m² in northern Greece. If you are not sure, call us.
How is it different from the ECO?
The frame: on the LP it is low and the cylinder reaches 130 cm above the roof surface. It suits places where height, wind or the look of the building call for a discreet installation. Mastersol gives the same factory warranties.
What does dual energy mean?
That the water is heated in two ways: by the sun and, when needed, by the 3.5kw electric element. If you want your heating boiler to heat it too, there are triple-energy models.
Does it withstand frost?
Yes. It runs on a closed circuit with antifreeze and withstands temperatures down to −47°C. The antifreeze is checked and topped up every year, depending on the area.
What warranty does it have?
5 years on the cylinder, serviced every 2 years. 10 years if you also fit an overheat valve (94°C / 6 bar), a 10 bar closed expansion vessel and a closed-circuit expansion vessel, with a yearly service. 15 years on the collectors and 1 year on the electrical parts. The warranty covers parts, not labour or transport.
