LINUO RITTER FP Series Flat Plate Solar Water Heaters Earn DCL Certification

DCL-Certified Solar Water Heaters Now Authorized for Sale and Installation in Dubai

Shandong Linuo Paradigma Co., Ltd. (brand: LINUO RITTER) is proud to announce that its FP Series Flat Plate Solar Water Heaters have officially received DCL (Dubai Central Laboratory) Product Conformity Certification – Certificate No. CL26021107, valid until August 12, 2027.

This certification confirms that the FP Series fully complies with BS EN 12975-1:2006+A1:2010 – the European Standard specifying requirements for durability (including mechanical strength), reliability, and safety for liquid heating solar collectors. The certification was issued by the Dubai Central Laboratory Department – Certification and Quality Control of Products Section (DCLD-CQPS) under Dubai Municipality, following assessment in accordance with DM-DCLD-RD-DP21-2001 (IC) – “General Rules for DM third party product certification system through factory assessment” and the relevant Specific Rules.

DCL certification is mandatory for solar water heaters sold or used within the Emirate of Dubai. According to Dubai Municipality Circular No. (183) of 2011, all new buildings must meet 75% of their hot water demand through solar energy, and swimming pools must meet 50% of their heating needs from solar sources. The solar heating system must be approved by the Dubai Central Laboratory. With this DCL approval, LINUO RITTER FP Series flat plate solar water heaters are now fully authorised for installation in building projects across Dubai.

Why DCL Certification Matters

Dubai Municipality Circular No. (183) of 2011

The foundation of Dubai’s solar water heating mandate is Dubai Municipality Circular No. (183) of 2011, which requires:

• New buildings to meet 75% of their hot water demand through solar power

• Swimming pools to meet 50% of their heating demand from solar sources

• The solar water heating system to be approved by Dubai Central Laboratory

• The system to be equipped with a backup system

• The design and planning approval to be handled by an engineering consulting office

Al Sa’fat Green Building Rating System

Dubai Municipality’s Al Sa’fat green building rating system is the primary regulatory framework for the built environment. All new buildings must achieve a minimum Al Sa’fat Silver rating. For Gold and Platinum ratings, solar water heating requirements apply to all building types. This means developers, contractors, and building owners across all project scales must specify DCL-certified solar water heaters to ensure compliance.

DCL Conformity Mark Requirement

Under DCLD regulations, DCL-certified solar water heaters must bear the DCL Conformity Mark as part of product marking. Certified manufacturers and registered local suppliers are required to ensure all DCL-certified products sold and used in Dubai carry this mark. Non‑compliance may result in suspension of the certification.

By choosing DCL‑certified LINUO RITTER flat plate solar water heaters, you gain:

✅ Regulatory Compliance – Meets Dubai Municipality’s mandatory certification requirements for solar thermal products
