Solar Thermal Stores and Hot Water Cylinders

Enviko provides a range of cylinders specifically for solar applications in mind, providing an efficient way of generating domestic hot water.  Each model features a dedicated high performance solar coil, transferring the maximum amount of heat from the solar circuit to the stored water.

The direct models are electrically heated cylinders, using the 3kW immersion heater supplied with the unit, with a high performance solar coil. They are capable of meeting the requirements of Building regulations, provided that it is matched to the panels and the hot water requirement correctly. The indirect cylinders are heated by a conventional boiler (either gas or oil) through a second high performance coil.  The primary coil is specifically designed to accommodate solar thermal and acts as the primary heat source always heating you hot water through the renewable source.

Resol C Plus Controls

Our range of Resol controllers is suited to all sizes of installation. The Resol C Plus can accommodate up to 4 temperature sensors and is user friendly making it ideal for domestic projects.  It can be mounted remotely away from the other system components allowing for easy access and monitoring.

  • System-Monitoring display
  • Up to 4 temperature sensors (PT1000)
  • 2 semiconductor relays for pump speed control
  • 9 basic systems to choose from
  • Heat quantity measurement
  • VBus Output
  • Function control
  • Thermostat function

BX Plus Controls

The BX Plus controller is designed for more complex installations mainly on a commercial scale.  It is equipped with 5 relay outputs and 9 sensor inputs, connections for digital direct Sensors, and PWM outputs for speed control of energy-saving high-efficiency pumps. With the integrated SD card slot, logging system data and updating the firmware is possible. Additional accessories as well as up to two extension modules, extending the controller by 6 sensor inputs and 5 relay outputs each, can be connected via the Resol VBus.

  • Extra-large graphic display
  • 5 relay outputs
  • 8 (9) temperature sensors (system-dependent)
  • 2 inputs for digital Sensors
  • 2 PWM outputs for speed control of high efficiency pumps
