Solar system kit Hewalex ZNP 24 DS DN 16 with solar collectors

Hewalex ZNP 24 DS DN 16 with solar collectors is a complete solar system kit designed for domestic hot water production and support of space heating systems. The kit includes matched collectors and the necessary hydraulic connections with DN 16 sizing to integrate into residential or small commercial solar thermal installations. The design focuses on dependable thermal energy capture and straightforward integration with existing boiler or heat-storage arrangements.

Advantages

The kit combines solar collectors and compatible hydraulic components engineered to work together, simplifying installation and reducing the need to source separate parts. DN 16 connections provide a common pipe size for domestic systems, which helps with compatibility and serviceability. The collectors are configured to optimise solar thermal capture for hot water and heating support, improving system efficiency when properly installed and connected to storage or heat-exchange equipment.

Suitable for

• Domestic hot water production in single-family homes
• Supplementing central heating systems in residential buildings
• Small commercial facilities requiring solar thermal support
• Retrofit projects where DN 16 connections are already in place

Key specifications

• System type: solar thermal kit with flat-plate or evacuated collectors (as supplied in kit)
• Intended use: domestic hot water and heating support
• Connection size: DN 16 hydraulic connections for integration with building plumbing
• Application scale: residential and small commercial installations

How to use

Install the Hewalex solar collectors on a suitably oriented and inclined roof or mounting structure to maximise solar exposure. Connect the collectors to the heat-transfer circuit using the provided DN 16 connections, and link the circuit to a compatible storage tank or heat exchanger. Integrate temperature sensors, controller, and safety devices according to local regulations and system design. Commission the system by filling and purging the circuit, checking for leaks, and setting controller parameters for collector operation and pump control.

Usage recommendations

For reliable performance, position collectors with unobstructed sun exposure and ensure correct hydraulic balancing and insulation of pipes. Use an appropriate heat-transfer fluid and fill procedure for your climate, implement frost and overheat protection where required, and follow local building codes. Regular maintenance such as checking connections, insulation condition, and controller settings will help maintain expected thermal output.
