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).
BESPOKE FEATURES
All Pro External Modules enjoy the same unique features as the Eco External Modules including the factory fitted multi-directional flue, high quality external powder coated casing, built in frost protection, mains isolating switch and a test switch. However, in addition, the boilers are factory wired to receive an ‘optional’ RF (radio frequency) wireless programmer. In this situation, the receiver can be plugged into the control panel of the module, enabling the boiler to be operated using a remote controller from any room inside the house, without the need for hard wiring.
SEALED SYSTEM KITS
Grant Vortex Pro external condensing modules can be converted to sealed system operation by purchasing a pre-assembled kit from Grant UK. The sealed system kit includes an expansion vessel (size varies), automatic air vent, pressure relief valve and circulating pump. A filling loop and pressure gauge are also supplied as part of the kit. These can be fitted within the module casing, or ideally in a convenient site within the building, located between the
cold main and central heating return.
