The solar water heater you control from your phone.
The Mastersol Plus combines collectors with a one-piece pressed aluminium casing with control from your phone over Wi-Fi. The casing has no joints or seams, for better sealing, corrosion resistance and lower heat losses. Plus collectors have a 25-year warranty.
From the app on your phone, on iOS and Android, you switch the system on and off, set temperature and schedules and get alerts. A home Wi-Fi network is needed; features may vary with the app version.
The collector and the jacket run on a closed circuit with antifreeze, for frost resistance down to −47°C. The tank has Bayer Double Duro Glass enamel, a magnesium anode, 5cm of polyurethane insulation and a 3.5kw electric element.
It is dual energy: the sun heats the water and, when needed, the 3.5kw electric element.
The range has eight models, from 120 litres with 2 m² to 300 litres with 5 m². It also comes in triple energy, for a connection to central heating.
Mastersol solar water heaters carry an A+ energy label and are CE and Solar Keymark certified.
What makes the difference
- Control from your phoneSwitch the system on and off remotely, set temperature and schedules and get alerts, from the app for iOS and Android. A home Wi-Fi network is needed.
- One-piece pressed casingThe back and sides of the collector are one piece of pressed aluminium, with no joints or seams. That gives better sealing, corrosion resistance and lower heat losses.
- Copper risersThe selective aluminium-titanium absorber covers the whole surface, on Ø22 & Ø8 copper risers that come out of the casing for the connection. 4cm of rock wool insulation.
- 3.2mm tempered glassThe safety glass stands up to hail and heavy rain. The circuit runs on antifreeze, for frost resistance down to −47°C.
- Tank with heat-exchange jacket2.5 or 3.0mm European steel depending on the model, Bayer Double Duro Glass enamel, a magnesium anode and 5cm of polyurethane insulation. A 3.5kw electric element.
- 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).

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.
What can I do over Wi-Fi?
From the app on your phone you switch the system on and off remotely, set temperature and schedules and get alerts. You need a home Wi-Fi network and an iOS or Android phone; features may vary with the app version.
Does the 25-year warranty cover the cylinder too?
No. The 25 years apply to the Plus collectors. The cylinder has 5 years, serviced every 2 years, or 10 years with the extension kit (94°C / 6 bar overheat valve, 10 bar closed expansion vessel, closed-circuit expansion vessel) and a yearly service. Electrical parts have 1 year.
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.
