Product Description
Detailed information about the product features and specifications

Maxi means savings
The Maxi Plus bivalent cylinder guarantees maximum use of renewable energy. The additional solar coil located in the lower part provides gradual heating of water throughout the entire tank. The maximally enlarged, double spiral coil in the upper part supports the operation of the collectors around the clock. It enables faster heating of up to 500 liters of domestic hot water.
Maxi means efficiency
Efficient, thick insulation guarantees comfort of hot‑water use around the clock. It ensures negligible heat losses and low operating costs.
Maxi means safety
Long and hygienic operation of the cylinder is ensured by top‑quality EXTRA GLASS® ceramic enamel and a set of anodes. The lower anode and the regularly replaced upper anode protect the tank interior and extend its durability. Optionally used active titanium anodes are maintenance‑free and require no servicing.
For cylinders with capacity:
- up to 300 liters – a small titanium anode is recommended,
- from 400 to 500 liters – a large titanium anode.
Maxi means expandability
The design of the SGW(S)B Maxi Plus cylinder enables quick and convenient installation. Connections located at the rear ensure a neat appearance. Only the optional GE electric kit is installed at the front. The lightweight outer jacket made of skai‑type material facilitates transport of the cylinder to the installation site. The standard jacket color is gray, but at no extra charge one of 2 additional colors can be ordered (red – catalogue no. ending 30, or white – ending 70). Adjustable leveling feet ensure stable placement.
Maxi means warranty
The best raw materials, advanced production technology and skilled staff guarantee the highest quality at every stage of production. This allows us to offer users of the Maxi Plus heat‑pump cylinder a 60‑month warranty (details in the warranty card).
