AD Wall-Mounted Water Heaters

AD Wall-Mounted Water Heater

The Adveco AD wall-mounted range of high efficiency condensing gas-fired water heaters is designed to provide a compact, high capacity and reliable method for delivering instantaneous hot water to a building.

The Adveco AD wall-mounted range is also compatible with proposed 20% hydrogen blends in natural gas networks, offering a transitional route to a more decarbonised energy without requiring physical alteration to the appliance or building.

Features & Key Technologies

Options

AD wall-mounted is a range of ‘A’ class energy efficient water heaters available in three rated heat outputs, 27 kW (AD16), 33 kW (AD22) and 61 kW (AD37). When combined with a water cylinder, AD wall-mounted helps meet peak withdrawals without increasing the water heater power. AD wall-mounted can also integrate with solar thermal systems to supply top-up heating when solar radiation during winter months is not enough to guarantee the required temperature for DHW demands.

The water heater features a single high-quality patented heat exchanger constructed from a continuous, non-welded run of AISI 316 Ti (Titanium) stabilised stainless steel, providing exceptional construction strength and corrosion resistance. With radial variable circulation, the heat exchanger recovers the latent heat of the flue gas, improving heat transfer for a net efficiency of up to 107% to produce domestic hot water (DHW).

With an efficient pre-mix burner and ultra-low NOX and CO emissions, the AD range is an eco-friendly way to serve a domestic hot water system. The unit additionally features a high 1:8 modulation ratio to ensure maximum efficiency even during periods of low demand.

By reducing energy consumption, AD can deliver operational savings of up to 30% compared to traditional water heaters for a wide range of commercial applications that demand large production of DHW, such as sports facilities, gyms, B&Bs, cafés, and other light commercial businesses.

Also included is an inbuilt controller with LCD display that ensures full temperature control and a maintenance self-check of primary components and functions.
