Boston’s Heat Pump Revolution: What Your Chimney Faces When You Ditch Gas Heating
Boston homeowners are embracing electric heat pumps at an unprecedented pace, with heat pump installations jumping from 18,362 homes in 2022 to 40,000 homes in 2024. This dramatic shift away from gas heating systems is reshaping neighborhoods across Suffolk County and Middlesex County—but it’s also creating a new challenge that many homeowners don’t anticipate: what happens to your chimney when you no longer need it?
The Heat Pump Boom Transforms Boston’s Heating Landscape
Market tracking shows that heat pumps have topped gas furnaces every year since 2021, shipping 4.1 million units in 2024—about 32 percent more than the 3.1 million natural gas furnaces. In Massachusetts specifically, the state’s climate plan calls for electrifying 26% of households by 2025 and 38% by 2030, translating to about 100,000 heat pumps installed by 2025 and 500,000 by 2030.
This transition makes sense for many Boston homeowners. A heat pump does not burn fuel, instead it uses electricity as its energy source, eliminating the need for gas lines and combustion systems. There’s no chance of carbon monoxide leaking into the home from a faulty furnace. While modern furnaces are very safe, they still present fire hazards that heat pumps don’t.
The Unused Chimney Dilemma
When you switch from a gas heating system to an electric heat pump, your chimney suddenly becomes obsolete. An unused chimney can cause serious problems, including heat loss, roof leaks, and wasted space in the home. An unused and unsealed chimney wastes energy like a small opened window. Even a sealed chimney is losing air through the masonry or any gaps in the seal.
Many Boston homeowners face a critical decision: should they remove their chimney entirely, cap it, or maintain it for potential future use? The answer depends on several factors unique to each property and situation.
Your Chimney Options After Heat Pump Installation
Complete Removal: The roof and floor have already been framed around the chimney, once it is gone then you will just have to frame in the openings. A competent carpenter should have no problems with this. However, you should consult with a structural engineer before taking on this project. After consulting with your expert, you’ll better understand whether this is possible in your home.
Partial Removal and Capping: After years of gradual replacements, when your chimney is no longer needed, you can cap your chimney and air-seal. Capping or removing the chimney will greatly eliminate your frozen pipe risk and your air leakage.
Maintenance for Backup Systems: Some homeowners choose to keep their gas systems as backup heating, especially during extreme cold snaps when heat pumps may struggle.
Why Professional Assessment Matters
Boston’s unique climate presents specific challenges for masonry structures. Boston’s freeze-thaw cycles are particularly hard on masonry, causing spalling bricks, failed mortar joints, and crown damage that lets water penetrate the structure. Even unused chimneys require professional evaluation to prevent structural issues.

Cost Considerations and Timeline
Chimney work varies significantly based on scope and complexity. Basic repointing work starts around $800-1500 for smaller areas, while crown repairs typically run $1200-2500. Extensive brick replacement or structural work can range from $3000-8000 depending on the scope. Every chimney is different, so detailed estimates after inspection are provided.
Most chimney repairs take 1-3 days depending on the scope of work. Simple repointing jobs might be completed in a day, while crown rebuilds or extensive brick replacement can take several days. Weather affects the timeline since masonry work needs proper curing conditions.
