100 Liters Solar Water Heater Price

I. Product Introduction

The 100-liter flat plate solar water heater is a high-performance, energy-saving hot water solution ideal for small households, apartments, and commercial spaces. The system consists of a flat plate collector and an enamel-lined water tank, combining aesthetics, efficiency, and long-lasting reliability.

The flat plate collector boasts a high-strength aluminum alloy frame and a low-iron tempered glass cover. Its sleek, modern appearance allows seamless integration with building roofs or balconies, enabling a perfect fusion of solar technology and architecture. Inside, the all-copper flow channel is coated with a highly selective absorber coating, ensuring high thermal efficiency and minimal heat loss. Even under cloudy or low-light conditions, the collector continues to deliver stable heat output.

The water tank’s inner liner is crafted from premium enamel material, processed through an 850°C high-temperature sintering technique. The result is a smooth, residue-free surface with exceptional corrosion and impact resistance, guaranteeing clean and hygienic water quality. With a compact 100-liter capacity, this system is perfectly suited for 2- to 4-person households, making it an ideal choice for urban high-rise apartments, new rural developments, and overseas villa projects.

III. Working Principle

The flat-panel solar water heater uses forced circulation and an intelligent controller for efficient operation:

1. Heat conversion – Sunlight passes through the low-iron tempered glass and is absorbed by the selective coating, heating the medium (antifreeze or water) inside the copper tubes.

IV. Product Advantages

Here is a concise version of the five key features:

1. Pressurized water supply – Uses tap water pressure for strong, stable flow, eliminating weak flow and temperature fluctuations.

2. Flat plate collector – All-copper channels with high-efficiency coating; sleek, embeddable design ideal for high-rises.

3. Enamel inner liner – High-temperature sintered, scale-resistant, and corrosion-proof; ensures clean water and a 15+ year lifespan.

4. Intelligent control – Features differential circulation, freeze protection, dry-burn protection, leakage protection, and timed heating; maximizes solar use and saves electricity.

5. Compact yet high-capacity – 100L in a small footprint for balcony installation; 50mm polyurethane insulation for excellent heat retention.

V. Factory Advantages

Here is a concise version of the company profile:

1. Qualified & Certified – ISO9001, ISO14001, Solar Keymark, CE, CB; compliant with EU, US, and Southeast Asia markets.

2. In-House Production – Automated enamel tank and flat plate collector lines; full quality control and on-time delivery.

3. OEM/ODM Capability – Customizable tank volume, collector size, heating power to meet diverse regional needs.

4. After-Sales Support – 3-year full unit warranty, 5-year core parts warranty; technical support and installation guidance provided.

VI. List of Accessories

Flat plate collector 100-liter enamel inner tank pressure solar water heater.

VII. Installation Precautions

1. Collector orientation - It is recommended to face south or 15° west of south. Avoid obstructions and the inclination angle should be close to the local latitude. 

2. Water tank location - Installed indoors or in a sheltered area, with a flat and sufficiently strong floor (able to bear twice the weight of the full water), and a drainage floor drain reserved at the bottom. 

3. Pipeline insulation - The pipes are wrapped with ≥ 20mm thick insulation cotton. In cold regions (below -10℃), it is increased to 30-40mm, and an outer waterproof layer is applied. 

4. Anti-freezing measures - In cold regions, add propylene glycol antifreeze (with a concentration of 30-50%) and set the controller to low-temperature circulation protection (start when the collector temperature is below 3-5℃). 

5. Electrical safety - Install leakage protection switches (≤30mA), ensure reliable grounding, and perform electrical component maintenance only after power is disconnected.

VIII. Application Cases

Urban apartment / high-rise residences \ Overseas villas \ Premium hotel (Small hotel / boutique hotel)

IX. Development Trends

With the ongoing implementation of green building and energy-saving policies, the solar water heating industry is undergoing the following key trends:

1. Flat-panel and balcony integration – Due to space constraints in urban high-rise buildings, flat-panel solar water heaters—compact and flexible to install—have become the mainstream choice for balcony wall-mounted systems, and their market share continues to grow.

2. Shift from stainless steel to enamel inner tanks – Traditional stainless steel inner tanks are gradually being replaced by enamel liners. Enamel tanks, with their superior corrosion resistance and water quality safety, have become the standard for high-quality solar and electric water heaters.

3. Multi-energy complementary systems – The industry is evolving from single solar systems to hybrid solutions such as "solar + heat pump" and "solar + gas," with intelligent controllers optimizing energy scheduling.

4. Smart upgrades – Products are increasingly integrating Wi-Fi modules, allowing users to remotely monitor water temperature, set heating schedules, and check system status via mobile apps, enhancing convenience.

Summary: The 100-liter flat plate solar water heater combines efficient heat collection from flat-panel collectors, the corrosion-resistant durability of an enamel inner tank, and a comfortable pressurized water supply. It offers an ideal energy-saving hot water solution for small households and commercial users. Please contact us for more product information and customized solutions!
