Vortex Pro External Module Condensing Range
|
The Grant Vortex Pro Range of external modules encompass Grant’s original Vortex heat exchanger and have some of the highest efficiencies available in the market today. The boilers are available in four outputs ranging between 15 and 46kW (50-157,000 Btu/h).
FEATURES
Grant Pro External modules feature the same unique benefits as the Eco External Modules, such as the multi-directional factory fitted low level flue, external powder coated robust casing, built-in frost protection, a mains isolating switch and a test switch. Additionally, the boilers are factory wired to receive an ‘optional’ RF (radio frequency) wireless programmer. With this, the receiver can be plugged into the control panel of the boiler, enabling the appliance to be operated using a remote controller from any room inside the house without hard wiring.
SEALED SYSTEM OPTION
Grant Vortex Pro external condensing modules can also be converted to sealed system operation by purchasing a pre-assembled system kit from Grant. The kit comprises: an expansion vessel (size varies), automatic air vent, pressure relief valve, circulating pump, filling loop and pressure gauge. These can be fitted within the module casing, or conveniently sited within the building, located between the cold main and central heating return.
