Kiwa Energy has been at the forefront of the use of BS845 to close the energy balance during continuous test work. Although not definitive, this technique is extremely useful at verifying useful efficiencies.

Please note that not every test method listed above is covered by our UKAS accreditation, but we apply the same technical rigour to all its procedures as if for UKAS accreditation.
Energy efficiency is an ever-increasing activity for us, and we are constantly developing new techniques and methods to test, for example, electrical water heater efficiency, electric oven efficiency, and boiler efficiency assessment under a dynamic heat load.

The EcoDesign regulation whilst in principle could apply to all products which use energy, is targeting various 'lots' of technologies in phased tranches. Among these first tranches are hot water boilers, water heaters, biomass boilers and standby electricity. Kiwa Energy is working with manufacturers across these areas to assist with compliance under the ErP.
