Ideal Replacement for Older Gas Wall Heaters

The DRU Art 3 Balanced Flue Gas Wall Heater is a powerful and dependable wall-mounted gas heater designed for homes, commercial buildings and public spaces. Delivering up to 3.5kW of heat output on Natural Gas or 3.1kW on LPG, the Art 3 provides effective heating for medium-sized rooms and larger spaces requiring supplementary warmth.

As the larger model in the Art Series, the DRU Art 3 combines proven balanced flue technology with quiet natural convection heating and robust construction. It operates without a mains electrical connection or traditional chimney, making it a practical independent heating solution for a wide range of buildings.

The DRU Art 3 uses a sealed balanced flue system with two concentric tubes. Fresh combustion air is drawn into the appliance from outside, while combustion gases are safely expelled through the inner flue.

Because combustion air is supplied directly from outside, the heater does not rely on room air for combustion. This makes the Art 3 a versatile solution for properties where a conventional chimney or open-flued appliance is unsuitable.

With efficiency of up to 78%, the Art 3 is designed to provide effective room heating while making good use of the gas consumed.

With a maximum output of 3.5kW on Natural Gas and 3.1kW on LPG, the DRU Art 3 provides more heating performance than the smaller Art 2.

Its output makes it particularly suitable for:

• Churches and chapels
• Church vestries
• Schools and classrooms
• Offices
• Community halls
• Conservatories
• Workshops
• Domestic properties
• Outbuildings
• Commercial premises

The Art 3 can be used as a primary heating source in suitable smaller spaces or as supplementary heating where additional warmth is required.

The DRU Art 3 distributes heat using natural convection, eliminating the need for a fan or mains electrical connection. This provides quiet operation while allowing warm air to circulate naturally around the room.

The heating system is designed to provide approximately 85% convection heat and 15% radiant heat, combining circulating warmth with direct radiant comfort.

The heater can reach full operating temperature within approximately 30 minutes, providing effective warmth when it is needed.

One of the key advantages of the DRU Art 3 is its ability to operate independently of mains electricity. This makes it particularly useful for buildings where electrical connections are limited or where an independent heating system is required.

The heater features an integrated modulating thermostat with capillary sensor for temperature control. An automatic time clock can also be connected where scheduled heating operation is required.

The DRU Art 3 is available for Natural Gas and LPG applications, providing flexibility for different properties and installation requirements.

It delivers:

• 3.5kW maximum output on Natural Gas
• 3.1kW maximum output on LPG
• Up to 78% efficiency

The LPG option makes the Art 3 suitable for properties without access to mains gas, subject to the correct appliance configuration and professional installation.

Built for long-term performance, the DRU Art 3 incorporates Ceramet-coated heat exchangers designed to provide durable and reliable operation.

The heater weighs approximately 16kg and features a robust steel construction. Available finishes include the classic beige enamel finish, with a white finish also available with additional corrosion protection.

A cool-touch control design helps make everyday operation safer, while an optional external terminal guard is available for installations in public or high-traffic environments.

The DRU Art 3 offers flexible installation options to accommodate different building constructions and wall thicknesses.

A telescopic balanced flue kit can be adjusted from approximately 250mm to 440mm, while a rigid 600mm flue kit is available for thicker wall constructions.

The Art Series can accommodate wall thicknesses from approximately 70mm to 980mm, depending on the selected flue configuration and installation requirements.

The DRU Art 3 provides a modern replacement option for older or discontinued gas wall heaters, including applications where a Baxi Brazillia replacement is required.

Its balanced flue design, independent operation and compact wall-mounted construction make it suitable for replacing older heating systems in churches, schools, offices, homes and other buildings.
