Nu-Heat individually sizes each solar system. The number of panels specified will vary depending on geographical location, hot water demand, orientation and angle of the panels and the amount of shading present from trees and buildings. Our specification process has been developed in conjunction with European solar design software, TSol, as well as the government's SAP building regulations assessment criteria. Up to eight collectors can be fitted from one pump station, so even the largest project can be catered for.

Hot water generation can be as high as 100% in the summer, but falls during the cooler months giving an average annual provision of up to 60% (depending on the environmental factors present). Every Nu-Heat quote states the estimated annual proportion of hot water the solar collector(s) will supply based on the individual demand for the household.

Flat plate collectors from Nu-Heat utilise the latest collector technology including prismatic glass and titanium oxide absorber coating, both of which maximize performance.

The integrated solar pumping station supplied with every system has simple-to-operate controls. It accurately measures the temperature of the roof panels ensuring that free energy is harvested whenever the hot water cylinder can accept it. Full thermostatic control of all elements of the system is important to maintain efficiency and to prevent heat from the cylinder's store being pumped back through the panels and lost to the atmosphere.
