Weatherproof and durable - High-quality materials for long-lasting use: This solar panel is made of high-quality, UV-resistant PP plastic and is equipped with a PC protective cover. This combination protects against sunlight, rain and temperature changes. The aluminium feet with plastic protective pads ensure a stable, scratch-resistant stand on any surface. Max. Water absorption: 15 litres. Winter break note: empty before the first frost, dry and store at 5-8°C.
Unique protective plate - Clean, powerful and durable: Our solar panel is equipped with an integrated protective plate made of PC material. This plate reliably keeps dust, pollen, leaves and insects away from the heating surface. For you: less cleaning effort, constant heating output throughout the season and a longer service life. The smooth surface can be easily cleaned with a soft cloth. So your solar panel remains efficient and visually appealing even after many months outdoors.
Environmentally friendly and cost-efficient - 100% solar energy: works completely with free solar energy - no electricity costs, no CO₂ emissions. The absorption rate depends on the orientation of the collector as well as the usable area. For best results, place the solar panel in the most sun-exposed place without shading. Ideal for environmentally conscious pool owners who want to reduce their energy costs while doing something good for the environment.
Effective solar energy use - Extend bathing season by months: Use the free energy of the sun to comfortably warm your pool water without additional electricity costs. Our solar panel made of UV-resistant plastic allows you to extend the bathing season by several weeks - enjoy warm water as early as spring and into autumn. The black surface absorbs maximum solar radiation and efficiently converts it into heat.
Easy to assemble - Includes adapter for 38 mm hoses: Thanks to the quick installation system, installation is easy even for less experienced pool owners. Does your pool filter have a 38mm hose? No problem - we supply 2 adapters (38mm) that fit our 42.5mm (inner diameter) or 50mm (outer diameter) connectors. Included in the pack: adapters, snap rings, O-rings and PTFE sealing tape.

Stainless Steel Fire Barrel: A robust, rustproof pool heater made of heat-resistant stainless steel (up to 300°C). More durable than iron or copper, even when stored outdoors. With vents for more efficient burning of firewood.
Safer & More Convenient Pool heaters come complete with tray and fireproof mats. A tray at the bottom of the pool heater protects the pool from ash, sparks or other impurities that may occur during the heating process. The fire mat creates a secure base and reduces the risk of floor damage from the combustion unit.
REINFORCED STAINLESS STEEL HEATPIPE The pool heater is equipped with a seamless stainless steel heating tube, which is particularly sturdy and durable. The diameter of the heating pipe has been increased to 20 mm to achieve higher water output and improved heating effect. It is possible to connect a hose with a diameter of 32 to 38 mm.
Pool heating fire: the water temperature is adjustable by the amount of logs located, while pools of different sizes heat up at variable speed. Note: Do not stack flammable materials near the pool heater.
POOL HEATERS WITH FIRE Regardless of electricity, sunlight, time of day or even the seasons, our pool heaters use firewood, briquettes or charcoal as fuel to heat your pool quickly and easily. Start the pool season as you like and enjoy swimming at a pleasant water temperature.

Main highlights

Wide size and high capacity: the solar panel is available in eight sizes from 300 x 70 cm to 600 x 140 cm and covers a wide range of applications. The smallest version with 4.7 litres is suitable for pools up to approx. 12,000 litres, while the largest version with 18.4 litres is designed for pools up to 48,000 litres. This gradation allows for precise selection depending on the pool size and desired heat output.
MODULAR SYSTEM FOR INDIVIDUAL ENERGY The sophisticated module system allows flexible expansion of the heating output by connecting several collectors in series. Depending on the desired water temperature and pool volume, the system can be individually adjusted. This allows for needs-based scaling from small to large pools and ensures optimal use of the available solar energy.
Effective water heating: the KESSER solar panel uses solar energy to heat the pool water and allows a temperature increase of up to 6 °C – depending on sunlight, flow and pool size. The heat-absorbing surface absorbs radiation efficiently while the water absorbs heat and is returned to the circuit for even heating without additional energy costs.
Comprehensive accessories for safe installation. Included are end caps, stainless steel hose clamps, hose adapters and Teflon tape for a tight and reliable connection of all components. The high-quality fasteners ensure secure installation and stable operation even during prolonged use. This ensures long-lasting use and efficient heat transfer throughout the system.
Compatible and easy to use: thanks to the standardised connection diameter of 32 mm and 38 mm, the solar collector is compatible with standard pool hoses as well as standard filter and pump systems. Integration into existing water circuits is uncomplicated and without complex adjustments. This allows the pool heater to be quickly put into operation and used efficiently.

Main highlights

Versatile: you have the option to operate our solar panels with 32 mm or 38 mm hoses. You can also use these solar heaters to support the operation of a heat pump.
The connection: you need a connecting hose in the diameter of your preferred diameter for the connection. The flow rate should be rather low. Technically up to 10 m³/h are possible, but that would be too much for good results. PTFE sealing tape is recommended for sealing.
Strong heat: If you provide enough collector space for your pool, then you can heat up your pool very well. Note that the use of a solar film is necessary for good results.
Reusable: For medium and large pools, the use of several collectors is necessary. This can greatly increase the effect.
CORRECT DIMINATION: A solar panel should come with a maximum of 6,200 litres of water, so that they achieve reasonable results in practice. For example, a pool with 12,400 litres requires two solar panels as a minimum.
