We‘re familiar with these labels on fridges, televisions and other electrical appliances. From September 2015, heat generators and water heaters will bear their own EU energy efficiency labels. These labels will make it easier to compare individual heating products and decide which ones to buy.
The EU Directive defines two product groups:
Lot 1: Heat generators for space heating only, and combi heaters for space heating and domestic hot water heating (gas, oil and electrical boilers, heat pumps and CHP units).
Lot 2: Water heaters and tanks. From September 2015, all of these must have a label.
Combinations of several products, such as heat generator with room controller or solar thermal system, are called packages and must also have a label. The values for these package labels are calculated on the basis of the efficiency values of the individual components. Packages pre-configured by the manufacturer will be delivered with package labels and the relevant fiches from the factory. This will simplify the work of dealers and installers.
With the introduction of the energy label, the need for skilled consultation from installers will increase. After all, the best efficiency class is not automatically the best solution for the customer. The rating takes no account of the investment and operating costs of products and systems. Only specialist analysis of the building‘s characteristics and the customer‘s requirements will result in sensible – that is, customized, efficient and cost-effective – solutions for space heating and water heating.
All ROTEX products are tested and meet the criteria in the Ecodesign Directive. For both individual products and packaged solutions, energy labels are a reliable indicator of efficiency class. Perfectly matched in terms of their individual components, our complete systems provide both maximum convenience and the highest safety standards.
Hooking up a solar thermal system is the most effective way to reach a higher overall system efficiency class. The ROTEX products (here GCU compact) are already optimised for linking up with a solar thermal system – when you connect it to a ROTEX Solaris, will become your own personal ‚solar heater‘. The integral central heating backup and large storage volume will raise your system‘s energy efficiency ratings for both domestic hot water and space heating.
