Trianco Aztec Electric Boilers
The Aztec range suits properties with no gas supply. Because they are electric, every unit converts effectively all the power it draws into heat at the point of use, and there is no flue, chimney or ventilation to fit. That makes them straightforward in flats and rural properties where a gas boiler is not an option.
They are quiet, slim and vertical, so they fit into small spaces, and they carry overheat protection, frost protection and a pressure relief valve as standard. Outputs run from 8kW to 14kW across system and combi models, and any of them can be paired with external heating controls.
Full specifications are in the Trianco Aztec brochure.

Why choose Trianco
Trianco is a long-established British manufacturer based in Sheffield, and the local team is a genuine difference against the multinational competition, both on product support and on answering a technical question quickly.
The range is broader than the boilers alone. Alongside the system, combi and instantaneous models, Trianco makes Aztec infrared heating panels from 400W to 1000W in ceramic and powder-coated finishes, and the Activair R32 air source heat pump at 12kW, for anyone moving away from direct electric heating altogether.
