ACV E-Tech electric boilers

ACV E-Tech electric boilers cover domestic and larger three-phase applications. Current E-Tech W models are wall-hung sealed-system boilers and can be used with hot-water cylinders, radiators and appropriately designed underfloor-heating circuits. We assess electrical capacity and system demand before specifying output.

ACV E-Tech domestic and commercial applications

ACV's E-Tech family extends beyond small domestic boilers. Wall-hung E-Tech W units include single- and three-phase variants, while larger E-Tech P products are aimed at higher-output and commercial duties. That makes the incoming electrical supply and phase arrangement a first-order design issue.

When we would consider an E-Tech system

Electric boilers can be useful where a flue is impractical, as a backup or top-up heat source, or in buildings without gas. ACV publishes wall-hung models that integrate heating-system components and can be paired with external domestic-hot-water cylinders.
