Scope
This document specifies the requirements and tests methods concerning the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of hybrid units.
A hybrid unit is composed of:
- a gas boiler as a heat generator which is able to supply the heat demand in all operating conditions;
- an electrical air-to-water heat pump, as a heat generator, which does not have to meet the heat demand in all operating conditions;
- a control unit (see definition 3.1.10).
A hybrid unit can include the facility to produce hot water, either by the instantaneous or storage principle, the whole being marketed as a single unit.
A gas boiler as part of a hybrid unit covered by this document is a gas-fired central heating boiler from the types C1 up to C9 and the types B2, B3 and B5, according to the classification in EN 1749:2020:
a) that have a nominal heat input (on the basis of gross calorific value) not exceeding 400 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021;
c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation;
d) where the maximum operating pressure in the water circuit does not exceed 6 bar;
e) which are classified as a gas-fired central heating boiler;
f) which are intended to be installed either indoors or outdoors in a partially protected place;
g) which are designed for either sealed water systems or for open water systems.
This document provides requirements for boilers with known constructions.
NOTE 1 For boilers with any alternative constructions, which might not fully be covered by this document, the risk associated with this alternative construction needs to be assessed.
NOTE 2 An example of an assessment methodology, based upon risk assessment and which covers the essential requirements of the Gas Appliance Regulation UE/426/2016, is given in Clause 11.
This document does not cover all the requi ...
