Tiled stove (grandfather clause)

Tiled stove (grandfather clause) refers to the legal protection that allows a tiled stove or wood-burning stove installed before the Federal Immission Control Ordinance (1st BImSchV) came into effect to continue operating despite stricter emission limits. Older solid-fuel stoves that do not comply with current limits for particulate matter and carbon monoxide may continue to be used-within certain time limits-due to grandfathering provisions. This issue has practical relevance for property owners in Nuremberg and Franconia, where tiled stoves are widely used as a traditional heating source in older buildings.

Legal Basis: 1. BImSchV and Grandfathering Periods

The First Ordinance Implementing the Federal Immission Control Act (1. BImSchV) sets emission limits for the combustion of solid fuels. The key limits for single-room combustion systems (wood-burning stoves, tiled stoves, masonry stoves) are:

• Dust: 0.04 g/m³
• Carbon monoxide: 4 g/m³

Stoves that do not comply with these values and were installed before March 21, 2010 (Phase 1) or December 31, 2014 (Phase 2) are subject to phased grandfathering provisions:

• Installed by December 31, 1994: The stove had to be either retrofitted (dust collector), subjected to a measurement, or decommissioned by December 31, 2014.
• Installed between 1995 and 2010 (Stage 1 stoves): Mandatory retrofitting or decommissioning by December 31, 2024, at the latest.
• Installed between 2010 and 2014: Transition period until December 31, 2024 (depending on the type approval date).
• Exceptions: Individually handcrafted tiled stoves (custom-made tiled stoves) are generally exempt from the emission requirements, provided they have been approved by a chimney sweep.

Important: Individually handcrafted tiled stoves are permanently exempt from the grandfathering issue, as they are not type-approved as mass-produced appliances.

What should be done if the grandfather clause has expired?

For older wood-burning stoves and heating stoves whose grandfather clause period has expired, the following options are available:

1. Measurement by a chimney sweep: A chimney sweep can measure whether the stove complies with current emission limits. If so, it may continue to be operated.
2. Retrofitting with a dust collector: Certified dust collectors are available for some stove types, which reduce particulate matter emissions to an acceptable level.
3. Decommissioning or replacement: If the stove does not meet the limits and retrofitting is not possible or not cost-effective, it must be decommissioned or replaced with a new, compliant unit.

The responsible authorized district chimney sweep monitors compliance with the 1st BImSchV and can order the decommissioning of a non-compliant stove.

Tiled Stoves as a Value-Adding Feature and Supplemental Heating

Despite regulatory restrictions, tiled stoves remain highly popular in old Franconian buildings and existing properties:

• Value-adding feature when selling: An original, preserved, and functional tiled stove-especially a handcrafted Wilhelminian or Art Nouveau tiled stove-is a sought-after unique selling point and can positively influence property value.
• Supplementary heating: Tiled stoves often serve as a supplement to central heating and reduce dependence on gas or district heating. As prices for fossil fuels rise, wood-burning stoves are regaining appeal as a cost-effective supplement.
• Radiant heat: Many residents find the warmth provided by radiant heat particularly pleasant, and it is an emotional selling point for older apartments and single-family homes.

Practical tip for homeowners in Nuremberg and Franconia

In the Nuremberg metropolitan region, tiled stoves are widespread in Wilhelminian-style buildings, Art Nouveau houses, and Franconian single-family homes. We recommend that owners have their stove’s compliance with the 1st Federal Immission Control Ordinance (BImSchV) checked by the responsible district chimney sweep-especially before a sale, to avoid any negative surprises for buyers. A non-compliant stove should be transparently disclosed in the property listing or checked for compliance with standards before marketing. Handcrafted tiled stoves from the 19th or early 20th century should be actively marketed as a feature-they represent quality and living comfort to our clientele.

Frequently Asked Questions

Do I have to decommission my old tiled stove if it does not comply with the 1st Federal Immission Control Ordinance (BImSchV)?

Yes, if the applicable grace period has expired and the stove does not meet the emission limits. The responsible chimney sweep will advise you on your specific case. Handcrafted, custom-made tiled stoves are largely exempt from this requirement.

Can I operate a tiled stove in a condominium?

Generally yes, provided the tiled stove is privately owned, has its own chimney or connection, and meets the emission requirements of the 1st BImSchV. Approval from the condominium association (WEG) is generally required if structural modifications to common property (e.g., the chimney) are necessary. In a rental situation, the landlord’s consent is required.

Is replacing an old tiled stove eligible for a subsidy?

The installation of a new, modern wood pellet stove or a certified log-burning fireplace may be eligible for funding through the BAFA (Federal Funding for Efficient Buildings - Individual Measures, BEG EM) under certain conditions, provided it is part of a comprehensive renovation with an individually prepared renovation roadmap (iSFP) or is used as the sole heat source. Simply replacing an additional fireplace that is not connected to the central heating system is generally not eligible for funding.

How much does a chimney sweep’s emission measurement report cost?

Emission measurements on an existing wood-burning stove or tiled stove performed by an authorized district chimney sweep typically cost between 50 and 150 euros in Bavaria, depending on the effort involved and travel expenses. The measurement checks whether the stove complies with the current limit values of the 1st Federal Immission Control Ordinance (1. BImSchV) for particulate matter (0.04 g/m³) and carbon monoxide (4 g/m³). The result is documented and can be submitted as proof to the relevant authority. Owners who wish to sell a stove or include it in a purchase agreement should have a current measurement report on hand to provide buyers with peace of mind.

Tiled Stoves in the Context of the Energy Transition

In the wake of the energy transition and rising gas prices, wood-burning fireplaces have seen a significant resurgence in demand since 2022. Tiled stove craftsmen in the Nuremberg-Fürth-Erlangen region report a sharp increase in waiting lists. Important for owners: Anyone wishing to have a new fireplace or tiled stove installed should take the current regulatory situation into account-new stoves must meet the requirements of the 1st Federal Immission Control Ordinance (BImSchV) from the outset and may only be operated with approved fuels. Pellets, natural firewood, and wood briquettes made from natural wood are generally permitted; treated wood, particleboard, and wood waste containing binder residues are prohibited. A violation can result in fines and orders from the chimney sweep.
