MISOL Solar Collector Of Solar Hot Water Heater
The MISOL solar collector features 10 evacuated glass tubes and a heat pipe system designed for hot water generation. Its outer shell uses aluminum alloy with a 1.8mm thickness, while the insulation relies on rock wool for overall efficiency. This setup aims to minimize heat loss while delivering steady solar heat into a domestic system. The unit’s vacuum tubes are 58mm in diameter and 500mm in length, suitable for compact installations and integrated with a metal manifold for reliable performance.
Duda Solar 30 Tube Collector 45° Frame
This SRCC-certified Duda Solar collector uses 14mm TU1 copper heat pipes and φ58mm x 1800mm tubes to maximize heat collection. The system includes a 45mm rockwool insulation in the manifold and a high-retention design to reduce heat loss. With dual copper and aluminum components and robust glass, it is built for reliable performance in moderate climates and can support efficient solar water heating with a medium to large storage tank.
MISOL 110V Controller For Solar Water Heater
The MISOL controller is designed for a separated, pressurized solar hot water system. It controls a single collector array, one storage tank, one pump, and auxiliary heating. The control unit measures temperature with three sensors (one PT1000 and two 10K NTCs) and has compact dimensions (approximately 187mm x 128mm x 46mm). This component is essential for automating temperature regulation and ensuring efficient system operation.
Duda Solar 30 Tube Collector 37° Frame
This variant from Duda Solar emphasizes a 37° frame, suitable for specific roof angles and sun exposure. It shares many features with other Duda collectors, including φ58mm x 1800mm tubes and a similar insulation profile. The combination of high-quality heat pipes and insulated manifold is designed to retain heat, supporting efficient hot water generation across different seasons and roof orientations.
Duda Solar 30 Tube Pool Collector
This pool-oriented collector is built to withstand chlorinated water. It uses a 316L stainless steel inner manifold and φ58mm x 1800mm tubes with evacuated designs for efficient heating in pool applications. The unit prioritizes corrosion resistance and durability, making it suitable for outdoor pool heating with lower maintenance over time, especially in coastal or chlorinated water environments.
Duda Solar 30 Tube Slope Roof Collector
Designed for slope roof installations, this Duda Solar model emphasizes a balance of heat pipe efficiency and tube performance. The package includes 14mm TU1 copper heat pipes, robust rockwool insulation, and the same high-quality glass used across the line. It aims to provide reliable hot water output while accommodating common residential roof angles and layouts.
Thaisan7 Solar Pool Heater
This outdoor solar pool heater by Thaisan7 is designed to extend the swimming season with solar energy capture through a clear lens and black coiled hoses that carry pool water. It is compact and aesthetically suited for external installation, with hoses sized for 1.5 inch connections. The design focuses on cost-effective pool heating and reduced energy use for larger outdoor spaces.
Buying Guide: Key Purchase Considerations
- System type and goals: Choose between domestic hot water and pool heating, as well as whether you need a dedicated controller or a full heat-pipe collector array.
- Climate and sun exposure: Install collectors with tubes and insulation suited to your average sunlight hours and seasonal temperatures to maximize efficiency.
- Tubing and materials: Evacuated tubes with copper heat pipes and robust glass tend to offer better performance in heat retention and durability in many U.S. climates.
- Mounting orientation: Frames at 37°–45° are common for residential rooftops, while slope and pool-specific collectors may require different mounting strategies.
- Insulation and heat losses: Rockwool or similar insulating materials in the manifold reduce heat loss, improving overall system efficiency.
- System components: A reliable controller, pump, and properly sized storage tank are essential for automation and stable hot-water supply.
- Water quality: Pool heaters should consider corrosion resistance for chlorinated water; domestic systems benefit from materials compatible with potable water.
- Maintenance and warranty: Look for SRCC certification or similar standards, along with clear guidance on service intervals and warranty terms.
