Sunex FISH Carbon S15 – compact, durable composite water storage tanks (Ultra-light fiberglass composite)

The Sunex FISH Carbon S15 also functions as a reliable hot and domestic hot water storage tank.

Capacity: 200 liters with minimal space requirements.

Hot water tank made of composite material in a vertical design, specially designed for domestic hot water preparation. The tank uses a large-surface heat exchanger, which enables efficient heat transfer from the heat pump, thus ensuring a fast and reliable supply of hot water. Thanks to the use of modern composite materials, the tank is characterized by a very lightweight construction, which reduces installation and space requirements, while offering a long service life. Another advantage is that no magnesium anode is required, which eliminates maintenance and minimizes the risk of anode corrosion. This combines robust corrosion resistance with low operating costs and high operational safety in household operation.

General Concept

The FISH CARBON S15 200 impresses with low heat losses, easy installation, and high durability.

Benefits:

The FISH CARBON S15 200 is a high-quality, vertical hot water storage tank specially developed for use with heat pumps. Thanks to its modern HDPE and fiberglass composite construction, it offers a long service life, lightweight design, and requires no magnesium anode.

The tank features a large-surface heat exchanger and ensures reliable domestic hot water preparation with high efficiency.

• Specially developed for heat pumps
• Large-surface heat exchanger for efficient heat transfer
• Light & durable thanks to composite material
• No magnesium anode required – reduced maintenance
• Energy efficiency class B
• Inner coating HPDE is corrosion resistant (also used in pipe systems, for example)

Structure:

Inner layer made of high-density polyethylene (HDPE); outer reinforcement by fiberglass composite material.

Advantages of the material structure: 

Excellent corrosion resistance, long service life, low weight compared to steel.

Design features:

All connections are located at the top, allowing flexible integration into different heating systems.

Weight:

Very light, typically 35 kg, which facilitates transport and installation.

Connection concept:

All connections centrally arranged at the top; facilitates integration into various heating systems.

Insulation:

30 mm PU rigid foam insulation minimizes heat losses and increases energy efficiency.

Rust-free:

Compared to steel models, rust formation is eliminated, simplifying maintenance.

Material structure: 

HDPE + fiberglass composite ensures stability, corrosion resistance, and long service life.

Versatility: 

Suitable as a hot and domestic hot water storage tank in heating and hot water systems.

Areas of application:

Suitable for new construction and modernization projects where compact size and low heat losses are important. 

Ideal for efficient operation with heat pumps – durable, low-maintenance, and reliable.

Installation:

Due to the central surface connection, flexible integration into central heating circuits, boiler or solar thermal systems is possible.

Maintenance:

Low maintenance requirements due to rust-free construction; regular inspection of connections is recommended, as with other storage tanks.

Important note! 

The installation and commissioning of the devices must be carried out exclusively by specialist personnel. In the event of a complaint, professional installation by qualified specialist companies (specialist contractor certificate and special qualification) must be proven. If no proof is provided, any warranty and guarantee will expire.

Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher GWP. A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming, proportional to the refrigerant's GWP value, than 1 kg of CO2, over a period of one hundred years. Do not attempt any work on the refrigeration circuit or disassemble the unit – always consult qualified personnel.
