The Alpha Protec Plus System is a fan-assisted condensing system boiler that is specifically designed for large properties where heating and hot water demands are greater.

It comes in four outputs of 50kW, 70kW, 90kW and 115kW, with the three larger units measuring in at 1038m (H) x 600mm (W) x 632mm (D). This model will require a separate hot water cylinder and can provide heating only for sealed central heating systems. However, it can be used with an open system if need be.

Priced at the more expensive end of the scale, the Protec Plus System with a standard 3-year warranty typically costs between £2,233.14 and £3,367.14. Please be aware that this guide price is for the boiler only and does not include installation fees.

Energy Efficiency Credentials

Alpha’s Protec Plus System is an A rated, ErP compliant system boiler with a seasonal space heating energy efficiency rating of 92%. Since it’s a condensing model, the boiler captures some of the heat that would otherwise escape and reuses this heat. This basically means that the appliance is more efficient as it uses waste heat to preheat the cold water that enters your boiler, helping to reduce your carbon footprint and lower your fuel bills along the way.

Protec Plus System Technology and Main Advantages

This efficient model by Alpha is equipped with a low power consumption pump and a frost thermostat that activates the pump and burner when the water temperature falls below 6 °C. It comes with a type B23 flue configuration to increase siting possibilities, but this can be changed to a type C with a flue adaptor kit.

Alpha’s Protec Plus System is suitable for single unit or cascade installations (where two or more boilers are used together to achieve a higher overall output). The boiler can also be supplied for use with natural gas or LPG (liquefied petroleum gas). Furthermore, all of the internal components can be accessed via the front of the unit to make servicing straightforward and less disruptive.

You’ll be pleased to learn that this boiler is user-friendly and features an LCD display and push-button controls to enable you to adjust the boiler and set temperatures in seconds. It even has built-in fault finding, an engineer mode for simple engineer setup and an external temperate mode which can be activated with an optional control.

Is the Protec Plus System the Right Boiler Type and Size for Your Home?

The Alpha Protec Plus System is for homes with larger output requirements and more than one bathroom. Put simply, this boiler is best suited to properties with very high heating and hot water demands and is even ideal for some commercial sites in need of a powerful boiler. If a higher output is required, it is possible to use two units together in cascade. Since you don’t need a feed or expansion tank, this model is also a great choice for dwellings with little or no loft space. Regardless of how big your home happens to be, you must ask a Gas Safe engineer to help you choose the right model and output to ensure your new boiler meets your needs.
