Article 28 Requirements specific to heating measures installed at on-gas premises
A heating measure installed at on-gas premises meets the requirements of this article if—
where the measure is installed at premises which, immediately prior to the installation of the measure, have an efficient heating system which is not broken down, the measure—
is—
a renewable heating system;
a district heating connection;
the installation of heating controls; or
an innovation measure; and
in the case of a replacement of the efficient heating system, is not a measure of the same kind as the heating system that is being replaced;
where the measure is installed at premises which, immediately prior to the installation of the measure, have an efficient heating system which is broken down and can be economically repaired, the measure—
is—
a renewable heating system;
a district heating connection;
the installation of heating controls;
an innovation measure; or
a repair of the heating system; and
in the case of a replacement of the efficient heating system, is not a measure of the same kind as the heating system that is being replaced;
where the measure is installed at premises which, immediately prior to the installation of the measure, have an efficient heating system which is broken down and is not economically repairable, the measure—
is—
a boiler, if the efficient heating system is broken down because a boiler forming part of that heating system is broken down;
a renewable heating system;
a district heating connection;
a central heating system;
an electric storage heater, but only if the efficient heating system which is broken down is an electric heating system or an electric storage heater;
the installation of heating controls; or
an innovation measure; and
is not a repair of the efficient heating system;
where the measure is installed at premises which, immediately prior to the installation of the measure, have an inefficient heating system (whether or not broken down), the measure—
is—
a boiler;
a renewable heating system;
a district heating connection;
a central heating system;
an electric storage heater, but only if the inefficient heating system which is broken down is an electric heating system or an electric storage heater;
the installation of heating controls; or
an innovation measure; and
is not a repair of the inefficient heating system; and
where the measure is installed at premises which, immediately prior to the installation of the measure, have neither an efficient heating system nor an inefficient heating system, the measure is—
a wet central heating system;
a renewable heating system;
a district heating connection;
the installation of heating controls; or
an innovation measure.
A heating measure installed at on-gas premises also meets the requirements of this article if—
the measure forms part of an ECO4 project which includes the installation of a district heating connection which meets the requirements of paragraph (1); and
the measure is a wet central heating system installed after the completion of the installation of the district heating connection.
