What types of condensing gas water heaters does Adveco offer?

Adveco offers several types of condensing gas water heaters including AD semi-instantaneous water heaters (70-280kW), ADplus instantaneous water heaters, BFC Cyclone storage water heaters (28-120kW, 217-480 litres), Innovo storage water heaters (12-32kW, 160-380 litres), SGE direct gas-solar storage water heaters with integrated solar coils, and Twister II stainless steel storage water heaters (35-45kW, 182 litres).

What is the difference between glass-lined and stainless steel water heaters?

Glass-lined water heaters (such as GLE, GLC, GLT, IT, and ITS ranges) are WRAS approved and ideal for hard water applications with working pressures up to 10 bar. Stainless steel water heaters (such as SSB, SSI, SST, ATSB, ATSI, and ATST ranges) are suitable for all water conditions and are available with working pressures of 6 or 10 bar. Stainless steel options often feature modular flanges and removable coils for easier maintenance.

Can gas water heaters work with renewable energy systems?

Yes, Adveco's gas-fired appliances can work in conjunction with solar thermal systems to provide a practical, highly effective, and low-cost renewable alternative to legacy gas water heating systems. The SGE range features integrated solar heat exchange coils for compact installations, whilst twin coil models like GLT, ITS, SST, and ATSR are specifically designed for use with renewables.

What are the benefits of semi-instantaneous water heaters?

Semi-instantaneous water heaters like the AD range offer compact floor-standing arrangements with high outputs from 70kW to 280kW. They provide on-demand hot water whilst maintaining a small storage capacity, making them space-efficient for commercial applications with high hot water demands.

What cylinder types are available for commercial hot water projects?

Adveco offers three main cylinder types: Buffer Vessels (for direct heating or electric immersion use), Single Coil Calorifiers (indirect water heaters with one heat exchange coil), and Twin Coil Calorifiers (indirect water heaters with two coils, ideal for combining conventional heating with renewables). These are available in glass-lined steel, stainless steel, or carbon steel construction depending on the application.

Which water heaters are best for hard water areas?

Glass-lined water heaters are specifically recommended for hard water applications. This includes the GLE, GLC, GLT buffer vessels and calorifiers, as well as the ST, IT, and ITS ranges. These WRAS approved vessels feature glass lining that protects against scale build-up and corrosion in hard water conditions, with working pressures up to 10 bar.

What are buffer vessels and when should they be used?

Buffer vessels are storage cylinders without internal heating coils, used to store pre-heated water from external sources such as boilers, heat pumps, or electric immersion heaters. They are available in glass-lined steel (GLE, ST), stainless steel (SSB, ATSB), and carbon steel (MSB, MSS) construction. The MSS premium range features multiple large flanged connections, baffle plates, and inspection ports, making them ideal for projects featuring heat pumps.

Are Adveco gas water heaters suitable for enhancing lower carbon status?

Yes, for buildings already on the gas network seeking to enhance lower carbon status, Adveco's highly efficient condensing gas water heaters working in conjunction with solar thermal systems provide a familiar, practical, and highly effective renewable alternative. These systems offer low operating costs whilst improving environmental performance compared to legacy gas water heating systems.

Condensing Gas Water Heaters

Adveco supports commercial new build and refurbishment projects with a wide selection of highly efficient condensing gas water heaters. Choose from glass-lined or stainless steel vessels with a range of tank sizes to meet project demands.

For buildings already connected to the gas network, simple replacement of ageing non-condensing water heaters with the latest generation of condensing technology is extremely advantageous. With greater thermal efficiencies comes as much as 35% savings on energy use, which operationally can save building owner/operators up to £220,000+ over a system’s lifetime.

For those seeking to enhance lower carbon status, replacement gas-fired appliances working in conjunction with solar thermal systems provide a familiar, practical, highly effective and low-cost to operate renewable alternative to legacy gas water heating systems.
