Perfectly suited for a larger home with high demand for both hot water and central heating, the ProTec Plus 50 has an output reach of 54kW, which is powerful enough to heat a property with up to 20 radiators and two bathrooms with baths. Many homes will not require a higher kW output than this boiler model, however, the range includes the ProTec Pro 50, 70, 90 and the ProTec Plus 115, which would be great for large commercial properties.

System boilers are ideal for those that need instant hot water, however, it is important to note when purchasing a new or a replacement system boiler, you will need to accommodate for an additional hot water storage tank. This is because the water is supplied directly from the mains, heated up, and then stored inside a hot water storage tank for when it's needed. Due to needing an additional tank, system boilers are not recommended for homes with limited space.
Most of the important parts of the hot water and heating system, such as the pump and expansion vessel are already built-in with a system boiler, making it quicker and easier to install.
