Grant Vortex 15/21 kW External Heating BoilerGrant Vortex 15/21 kW External Heating Boiler  Ref: VTXOM1521
Vortex Pro External Module 15/21 Kw

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).
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.
