ACV E-Tech P High-Output Three-Phase Electric Boiler

ACV E-Tech P High-Output Three-Phase Electric Boiler

ACV E-Tech P electric boiler

The ACV E-Tech P is a high-output, floor-standing three-phase electric boiler designed for commercial buildings, industrial heating systems, large properties and applications requiring substantial electrical heating capacity.

The E-Tech P range is available in five output levels: 57.6kW, 115.2kW, 144kW, 201.6kW and 259.2kW. Each model uses a 400V three-phase power supply and can provide staged heating control to match the required load.

With no combustion process and no flue requirement, the ACV E-Tech P can be considered where a high-output electric heating solution is required and suitable three-phase electrical infrastructure is available.

ACV E-Tech P Models

The exact staged power configuration varies by model. ACV documentation confirms the five model range and the corresponding electrical outputs.

Four-Stage Electric Heating Control

The ACV E-Tech P uses an electronic sequencing controller with four-stage modulation. The system progressively brings heating stages into operation according to the required heat demand.

The maximum power can also be limited to 25%, 50% or 75% using the manufacturer’s specified configuration method.

This makes the E-Tech P suitable for heating systems where controlled staged electrical output is required rather than a simple single-stage electric heat source.

Commercial and Industrial Heating Applications

The ACV E-Tech P can be considered for applications such as:

• Commercial buildings
• Large residential properties
• Apartment buildings
• Schools and educational facilities
• Healthcare facilities
• Industrial buildings
• Workshops and production facilities
• Warehouses
• Large offices
• Backup and emergency heating systems
• Gas-free heating installations
• Multiple-boiler heating systems

The appropriate model should be selected according to the building heat-loss calculation, hydraulic design and available electrical capacity.

Three-Phase Electric Boiler for Large Heating Systems

The E-Tech P is specifically designed for installations where substantial electrical heating output is required.

The models use 3 × 400V three-phase electrical power, while the control circuit uses 230V single-phase power. Electrical demand is substantial, particularly on the higher-output models, so the installation must be designed around the manufacturer’s electrical specifications and the site’s available supply.

Heating System Compatibility

ACV states that the E-Tech P is suitable for connection to most sealed heating and hot-water systems, with a maximum working pressure of 4 bar and maximum temperature of 90°C. It can also be connected to external storage cylinders for domestic hot-water production where the system is designed for this purpose.

E-Tech P Heating Elements

The boiler uses removable stainless steel Incoloy 800 heating elements mounted from the front of the heating body.

The heating body is constructed from mild steel and is hydraulically tested before operation. The maximum operating pressure is 4 bar.

Installation Requirements

The ACV E-Tech P is a commercial-scale electrical heating appliance and should be specified and installed by appropriately qualified heating and electrical professionals.

Before purchasing, confirm:

• Required boiler output
• Building heat-loss calculation
• Available three-phase electrical supply
• Electrical protection requirements
• Hydraulic system design
• Heating-system operating pressure
• Pipework and connection requirements
• Plant-room access and dimensions
• Local electrical regulations
• Local heating and building regulations
• Whether additional system controls are required

ACV documentation specifies that the boiler’s power circuit operates at 400V three-phase and that the control circuit operates at 230V single phase.

Important Frost Protection Information

The E-Tech P is not fitted with integral frost protection. ACV recommends a suitable external frost thermostat where the boiler is installed in a location where freezing may occur.
