Draft Act amending the Constitution, reissuing the Hamburg Climate Protection Act and amending further provisions (document 21/19200

Re 6.1: ‘§ 11 HmbKliSchG-E (restrictions for the new connection and replacement of electric heaters) in connection with § 3, subparagraph 7 HmbKliSchG-E’

The provision prohibits the new connection of permanently installed direct electric heaters used to generate space heat with an output of more than two kilowatts for each residential, operating or other usage unit. After 31 December 2025, the exchange and replacement of direct electric heaters will also be prohibited. The provision also contains
exemptions. § 3, subparagraph 7 defines the term direct electric heaters (formerly referred to as electrical direct heaters and night storage heaters).

Re 6.2: ‘§ 12 HmbKliSchG-E (restrictions for certain boilers) in connection with § 3, subparagraph 8 HmbKliSchG-E’
The provision prohibits the new connection of boilers powered by liquid fossil fuels from 31 December 2021. This does not apply to boilers powered by liquefied gas. The ban will also apply to the exchange and replacement of these boilers after 31 December 2025. The provision also contains exemptions. § 3, subparagraph 8 defines the term boiler. The term is based on the definition in § 2, subparagraph 7 of the Energy Saving Ordinance of 24 July 2007 (Federal Law Gazette I p. 1519), last amended pursuant to Article 3 of the Ordinance of 24 October 2015 (Federal Law Gazette I p. 1789).

Re 6.3 ‘§ 13 Restrictions for mechanical space cooling’
The provision prohibits the new installation of air conditioning and ventilation systems or components for the mechanical cooling of buildings or human occupancy areas if the intended use cannot be achieved in an economically justifiable manner by structural engineering or other suitable measures. Space conditions that, contrary to generally accepted engineering practice, require a higher level of energy usage will not be permitted. By means of an ordinance, the Senate will determine those buildings and human occupancy areas for which mechanical space cooling is permitted.
