The energy sector is experiencing a constant and fast-paced period of change as the UK Government strives to meet its 2050 Net Zero targets and, in turn, seeks to decarbonise the energy network. The challenge for heating manufacturers is developing new innovative products which respond to the needs of the user, many of whom will still require products that work off gas.
In response, leading heating manufacturer Alpha has launched the ProTec NX to its portfolio of gas boilers, offering a high-efficiency, fan-assisted condensing boiler for commercial applications, as well as larger domestic projects. With the maximum efficiency available for condensing boilers, the ProTec NX improves running costs and has ultra-low emissions to meet the latest building regulation and authority requirements.
Available in six individual outputs ranging from 48kW up to 180kW, the boiler range has the capability of cascading to achieve higher outputs and increase load flexibility. Its wide 1:10 modulation range enables the boiler to run at a low output with fewer on/off cycles, reducing emissions and increasing component longevity.
For installers, the ProTec NX offers an easy-to-fit unit which can be wall-mounted or fixed to a freestanding low or ultra-low frame. The boiler is factory-fitted with a room-sealed ‘C’ flue type configuration but is also compatible with ‘B23’ or twin flue systems using the stub kit.
The new range offers a more compact, space-saving solution, especially when banking boilers together with a range of flue options for individual, cascaded and different ventilation scenarios. A wide range of hydraulic accessories is available to link boilers, and plate exchangers and low loss headers to feed multiple heating and hot water zones.
Commercial Controls
The ProTec NX has an inbuilt option within the boiler control panel capable of setting programs, temperatures and zones to suit the system need. Using Alpha’s smart commercial controls, it’s possible to link multiple boilers in cascade and drive them all from one ‘master’ boiler.
Alternatively, installers can use separate controls to manage the ProTec NX, either using Alpha’s own cascade controller or a separate panel from the plant room. Input from these can be simple ON/OFF control; or using OpenTherm compatibility according to the required demand and energy-saving requirements.
The commercial controls engineered by Alpha are not only technologically advanced but compatible with a broad spectrum of market options, ensuring seamless integration and maintenance. While the controls for these boilers are undeniably more advanced than those of domestic counterparts, the art of mastering them is within reach for installers when armed with the right training – offered within Alpha’s commercial training course.

Darran Smith, technical manager for Alpha, comments: “Our new ProTec NX range offers a brand-new innovative gas boiler for commercial premises that require a boiler system upgrade. Updating our former ProTec Plus range, NX enables greater ability to link and cascade boilers, depending on power required, and seasonal and building load demands.
“All models are approved and certified for hydrogen blended gas when the network begins to offer it, to further reduce carbon levels towards the decarbonising goals. Weather compensation also comes as standard, with the use of a sensor to monitor outside temperature and adjusting the output of the boiler to suit the demand and desired internal temperature.
“It is vital for installers to understand the requirements and controls of this system, and the vast opportunities it offers in commercial projects. We offer a wide number of training courses to assist installers in doing this.”
