Description
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.
This range covers the 100 to 160-litre models, with 1.5 to 3 m² of collectors. There are also 200-litre LP models and triple-energy versions.
Mastersol solar water heaters carry an A+ energy label and are CE and Solar Keymark certified.
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.
Highlights
What makes the difference.
What every LP comes with, from the low frame to the tank.
Double Duro Glass tank
2.5mm 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 certified
The 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 frame
A 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 antifreeze
The 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 Greece
Mastersol 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.

Warranty & installation
We are here after you buy.
5 yearson the cylinder, serviced every 2 years
10 yearson the cylinder, with the extension kit and a yearly service
15 yearson the solar collectors
1 yearon the electrical parts
The extension kit is an overheat valve (94°C / 6 bar), a 10 bar closed expansion vessel and an expansion vessel for the closed circuit. The warranty covers parts, not labour or transport, and does not cover the collector glass.
The system must be installed by a licensed plumber. The warranty form is filled in, signed and emailed to Mastersol (info@mastersol.gr), together with proof of each service.

Questions
Ask us before you buy.
Our technicians answer every question, from choosing to installing.
2610 334 389 info@climaventis.grWhich 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.
What servicing does it need?
Every 2 years the magnesium anode rod and the safety valves are replaced, or every year for the 10-year warranty. Every year the antifreeze is checked and topped up. The technician signs the warranty form and gives you a service receipt.
How are delivery and installation done?
The solar water heater ships by carrier throughout Greece; you see the shipping options and cost in the cart. A licensed plumber installs it, which is also a condition of the warranty; we can suggest a partner in your area.
Complete the installation
For the 10-year warranty.
The cylinder warranty becomes 10 years with an overheat valve (94°C / 6 bar), a 10 bar closed expansion vessel and an expansion vessel for the closed circuit, plus a yearly service. Here is the Mastersol closed-circuit expansion vessel.
