From 26th September 2015 all heating and hot water products, with an output equal to or less than 400kW will be affected by the Energy related Products (ErP) directive that comes into force. Energy labels are used for assigning heat pumps to individual classes based on their energy efficiency (heating efficiency). The best class is marked A++, the worst G. The deciding factor for determining energy efficiency is the seasonal SCOP heating factor. Methodology for determining energy efficiency is defined in BS EN 14 825.
As a result of the advanced technology and inverter drive, the MasterTherm heat pumps are positioned among the most efficient and effective heat pumps on European and International markets.This is reflected in their classification and achieved heating efficiency µs. The majority of Inverter driven MasterTherm heat pumps already comply with the future highest class of A+++ (coming into effect in 2019).

The seasonal heating factor represents the ratio between the total produced heat and the total electricity consumption. In contrast to the COP heating factor, which is specified for particular temperature conditions (for example, COP=3.2 at A2W35 – air temperature of 2 °C and heating water temperature of 35 °C), SCOP is calculated for the entire heating season. The SCOP factor thus characterises the real efficiency of heat pumps much more accurately conditions than the COP factor.
Seasonal energy efficiency µs represents a degree of utilisation efficiency of unrenewable primary energy by a particular heat pump. It is calculated as a ratio between the given heat pump seasonal heating factor and the electricity production and distribution coefficient, stated in %. For example, shall the seasonal energy efficiency amount to 150%, the heat pump will, during the entire heating season, supply energy that is by 50% greater than its primary energy consumption (i.e. the consumption of unrenewable energy necessary for the production of electricity for driving the heat pump).
For assessment purposes, 2 types of applications are recognised: medium-temperature applications, when the heat pump provides an output temperature of 55 °C, and low-temperature applications with an output temperature of 35 °C.
