I got a heat pump and my energy bill went up
Switching from gas furnaces to electric heat pumps doesn’t always lower household energy bills, especially in regions with high electricity prices or confusing utility rate plans. Commenters trade numbers on gas vs. electric costs, heat pump efficiency, climate and housing differences, and note that policy tools like subsidies, tax breaks, and fairer tariffs can make or break the economics. Many argue that while electrification is essential for climate and health reasons, it must be cheaper and simpler to manage if it’s to work for typical households rather than just affluent early adopters.
Access to the article / paywall debate
- Many objected to the email/content gate on the site, saying they won’t create accounts or risk more spam.
- Several shared tactics to bypass such “soft paywalls” (fake emails, temp mail, disabling JS).
- The content gate was later removed; readers appreciated having the full text and even a PDF version without signup.
- Some felt the clickbait-ish title plus earlier gate skewed initial reactions, as the article itself is more nuanced.
Heat pump vs gas: costs and COP math
- Multiple commenters ran back-of-the-envelope calculations: where electricity is ~$0.10/kWh or less, heat pumps can beat gas; at ~$0.25–$0.50/kWh they often lose, especially in places like California.
- Others stressed using seasonal COP/SCOP, not worst‑case COP, and noting that mild climates or UK‑style winters often yield COP ~3–4.
- There’s disagreement on whether environmental benefits justify higher bills for households on tight budgets.
Utility rate plans and optimization
- Central point repeated from the article: being on the wrong electric rate plan can make a heat pump look uneconomical even when the hardware is fine.
- California/PG&E was cited as having many confusing plans and very high delivery charges.
- Suggestions included automatic plan optimization by utilities and treating energy use as an “optimization problem” with spot pricing, solar, and batteries.
Grid, renewables, and externalities
- Some argue long‑term trends favor electricity: diverse generation (including renewables, nuclear) and home solar make it more resilient than piped gas.
- Others fear grid-upgrade and storage costs will keep end-user electricity prices high.
- Debate over whether externalities of fossil fuels should be priced in; some say current CO₂ damages would flip the economic calculus, others doubt realistic pricing is politically achievable.
Installation, modeling, and practical issues
- Several emphasize that proper design (Manual J or better, blower-door tests, correct sizing, second-stage heat crossover point) is rarely done in residential installs.
- Defrost cycles in cold climates can sharply reduce effective COP if not accounted for.
- Passive-house and high-insulation approaches were mentioned as an alternative path that can nearly eliminate active heating.
User anecdotes and regional variation
- Reported outcomes range from ~75% savings (e.g., Denmark with gas expensive and electricity tax breaks) to 4× higher operating cost (California with very high electric rates).
- Some users in cold regions (Canada, UK, Boston, Netherlands) report savings or rough parity, especially with incentives or solar; others find gas still much cheaper.
- A recurring theme: economics depend heavily on local electricity/gas price ratios, climate, tax/subsidy structures, and whether gas is fully disconnected (to avoid fixed charges).
Equity, simplicity, and adoption barriers
- Several note that rate structures, modeling, and device control are too complex for average homeowners; many will default to gas as the “path of least resistance.”
- There are calls for:
- Cheaper, more stable electricity as a prerequisite for mass adoption.
- Simple, “idiot-proof” tariffs and automation that handle optimization.
- Policy tools (tax breaks, targeted subsidies, low-interest loans) that make switching affordable beyond the upper-middle class.
