Wall-hung Gas Boiler R5L

The R5L Series Gas Heating & Hot Water Boiler is designed to meet the demands of modern home heating, offering a perfect blend of efficiency, intelligence, and safety. Available in 24kW and 28kW models, it provides consistent heating for radiators (30–80℃) and underfloor systems (25–60℃), while delivering a steady supply of hot water (35–60℃) with a 10L/min flow rate. Its compact, Arctic Blue brushed metal design, with a touchscreen display, adds a sleek, modern look to any home.

At its core, the R5L Series features a plate heat exchanger paired with a German Wilo circulation pump and a Japanese Mikuni gas valve, ensuring optimal heat transfer, precise gas regulation, and reliable performance even under heavy use. The boiler’s forced ventilation system and IPX4D protection rating make it safe for installation in bathrooms and other humid environments, while its 48 layers of safety protection—including anti-freeze, anti-dry burn, and pressure relief features—provide round-the-clock peace of mind.

Smart technology is at the heart of the R5L experience. With WiFi connectivity, you can control your boiler remotely via a mobile app, adjust temperatures, set schedules, and switch between “At Home,” “Away,” and “Sleep” modes from anywhere. The four-point temperature control system minimizes hot water fluctuations, ensuring a consistent and comfortable bathing experience, while the gas consumption monitoring feature helps you track and reduce energy use.

The R5L Series is also engineered for longevity and low maintenance. Its stainless steel coaxial flue and corrosion-resistant components can withstand 100,000 water hammer impacts, and the gas valve is tested for 300,000 on/off cycles. With a 2nd-class energy efficiency rating and a three-stage modulation system, it adapts to your heating needs to save energy and lower utility bills.

Frequently Asked Questions

Q: How can I ensure the safety of using a gas water heater?

A:
Our gas water heaters are equipped with multiple safety features. Most models have a “7 + 2” maximum protection system, which includes measures like over - temperature protection, anti-dry-burning protection, and flame-out protection. Additionally, features such as error warning systems and water-pressure release devices further enhance safety. Regular maintenance and inspection as per the user manual are also recommended.
Q: Can the gas water heater maintain a stable water temperature?

A:
Yes, our gas water heaters are designed with advanced temperature control technologies. For instance, micro-flame technology allows for precise adjustment of the flame, enabling accurate temperature control. Smart self-adaptation features can also adjust to changes in water pressure and gas supply, maintaining the water temperature within a narrow range, typically ±0.5℃.
Q: How energy - efficient are these gas water heaters?

A:
Our gas water heaters generally have high efficiency ratings, often exceeding 88%. Models with advanced features like condensing technology can further improve energy efficiency by recovering heat from the exhaust gases. Choosing a high-efficiency model not only saves on energy costs but also reduces environmental impact.
Q: Can I install a Macro wall - hung boiler by myself?

A:
We strongly advise against self - installation. Wall - hung boilers involve gas or electrical connections and complex plumbing work. Professional installers are trained to ensure proper installation in accordance with safety standards and local building codes. They can also perform necessary commissioning to make sure the boiler operates safely and efficiently. If you attempt to install it yourself, it may void the warranty and pose safety risks.
Q: What are the key safety features of your wall - hung boilers?

A:
Our wall-hung boilers are equipped with multiple safety protection measures, typically around 48 types. These include over-temperature protection, which prevents the boiler from overheating; anti-freeze protection to safeguard against damage in cold weather; and pressure relief protection to maintain safe operating pressures. Additionally, features like flame failure protection ensure that the gas supply is cut off if the flame goes out unexpectedly.
Q: How do I choose the right gas water heater capacity for my household?

A:
The capacity you need depends on the number of family members and your hot water usage patterns. For example, if you have a small family with normal hot water demand, a model with a rated hot water capacity of 12 - 16L/min (like some models in our range) might be sufficient. But for larger families or those with higher hot water consumption, such as frequent bathtub filling, you may need a model with a higher capacity, like 18 - 20L/min.
