Download PDF System schematic of a sealed system with a large boiler as the heat source. The system has six central heating or domestic hot water (DHW) zones. This schematic highlights how the NRG Zone manifold can handle large boilers even though it only has 1″ connections. In this schematic the boiler has 1.5″ flow […]
Download PDF System schematic of a sealed system with a heat pump, a radiator circuit, an underfloor heating zone and a domestic hot water (DHW) cylinder. The NRG Zone 4 manifold ensures that the heat pump receives the coldest possible return water so that it is working under optimum conditions and with optimal efficiency. The […]
Download PDF System schematic of a system with two oil boilers, solar panels and two optional gas boilers as the heat sources. The outputs are an underfloor heating zone, a radiator zone and a domestic hot water (DHW) cylinder. The DHW cylinder has two coils and can either be heated from the solar panel, or […]
