Energy efficiency labeling to meet the ErP Directive

Viessmann supports market partners with service package

From September 26th, 2015, it will be mandatory for trade

professionals to include efficiency ratings in their quotes for heat

generators, DHW generators, storage cylinders, and for entire

systems in order to adhere to the EU guideline. They will also be

required to specify the efficiency class of products in brochures

and advertisements and to attach energy efficiency labels to units

on display. Viessmann has created a comprehensive service

package to help their market partners meet this requirement: product labels for the individual products, a universal label for the factories for package solutions put

together from the package price list, delivery service of universal labels for systems that trade

professionals configure themselves using Viessmann

components, label-generating software for trade professionals.

Product labelsFrom the September deadline onwards, product labels and fact

sheets will be available for all heat generators, DHW generators,

and storage cylinders. The efficiency rating, which is based on the

relevant EU regulations, will be specified on the product labels and

the fact sheets as well as attached to the relevant products. For

heat generators, efficiency will be rated on a scale ranging from G

to A++ and depicted on said scale by a black arrow. Specifications

will also be included on output and noise emissions. The labels for

CHP units will include an additional symbol for power generation.

The labels for heat pumps will show two efficiency ratings: one for

the flow temperature of 55°C and another for 35°C. In addition,

specifications on output will be provided for three climate zones

(symbolized by a small EU map with three differently colored

areas) for heat pumps. There will therefore be six different values

on the labels: two flow temperatures for each of these three

climate zones. DHW generators and storage cylinders will also

have an own label with a scale rating efficiency from G to A.

Universal labelsThe purpose of the universal label is to provide a comprehensive

statement on the energy efficiency of an entire heating system.

This is calculated based on the different product fact sheets – for

example, by taking into account the values for the heat generator,

controller, storage cylinder, and solar collectors. The relevant

calculation methods are set out in the EU regulations. In the future,

trade professionals will be obliged to specify the overall energy

efficiency of an entire system to their customers in their quotes and

provide the label when installing the system. The Viessmann

market partners have the advantage that all of the Viessmann

components are compatible and therefore function perfectly with

one another. In addition, they do not have to put any resources

into creating the universal label, as calculating and providing the

label is an integral part of Viessmann's service package.

Top ranking for integrated systems with Viessmann product rangeThe universal label for an overall system can achieve a better

efficiency rating than the system's individual components, which is

why the scale on the label goes up to A+++. A system with a

primary heat generator rated as A can therefore be rated as A++

when combined with a solar thermal system rated as A+ or with an

additional heat pump. This rating system therefore clearly

highlights the appeal of bivalent and multivalent systems. The

Viessmann comprehensive range of products contains perfectly

matched system components for all areas of application and all

fuel sources. In addition, superordinate control systems leverage

the efficiency potential of different system configurations.

Viessmann packages labeled at the factoriesFor pre-configured system solutions made up of components from

the package price list, trade professionals do not have any

workload creating the universal label. Viessmann will deliver

finished universal labels and data sheets for these systems so that

they can be directly included in the quote. Combination units,

compact systems, and pre-configured packages with DHW

cylinders specify the energy efficiency ratings for room heating and

DHW generation.

Products delivered without labels before the deadlineAlthough heating products placed on the market before September

26th, 2015, will not have energy efficiency labels, they can still be

sold, installed, and commissioned after this date. Trade

professionals can therefore be sure that they will be able to sell

and install deliveries they received before the deadline or products

from stock.

Labels are not initially required for domestic ventilation systems

and biomass boilers. Experts at the EU Commission are currently

working on regulations for these products. Energy efficiency labels

will probably not be introduced for them until 2016 or 2017. In

principle, solar components such as collectors and solar pump

assemblies do not require product labels. As solar heating is

always combined with other heat generators, the EU regulations

only require product data sheets, which are then used to determine

the universal label.

Legal basisThe purpose of the new, uniform pan-European energy efficiency

label is to introduce a benchmark and decision-making aid for

building contractors and renovators buying new heating systems.

The legal basis for this is provided by the Energy Labeling

Directive 2010/30/EU, the ErP Directive (Energy-Related Products

Directive), and the EU regulations:

2013/811/EU on the energy labeling of room heating

systems, combined heat and power generation units, and

universal systems. These include boilers with outputs up to

70 kW for oil and gas, heat pumps, CHP units, and

integrated systems with solar collectors and controllers.

2013/812/EU on the energy labeling of DHW generators

DHW cylinders with a capacity of up to 500 liters and

integrated systems.
