The Heating Infrastructure
Built Into the Neighborhood

Burbas designs and operates shared geothermal loop networks for residential developments — clean heating and cooling delivered as a utility-style service.

IRA tailwinds. All-electric mandates expanding. Developers under pressure to deliver net-zero buildings without cost volatility. The infrastructure layer for neighborhood-scale decarbonization hasn't been built — until now.

The Problem

45% of U.S. Emissions Come From Buildings.
Most Decarbonization Plans Stop at the Roof.

01

Gas Heating Isn't Going Away on Its Own

60 million U.S. homes run on natural gas for heat. Electrification efforts focus on new construction and largely ignore the installed base. The infrastructure gap is enormous — and growing.

02

Individual Heat Pumps Don't Scale

Per-unit air-source installation costs remain high. Grid demand spikes are unmanageable at density. Retrofits require homeowner coordination that rarely materializes at neighborhood scale.

03

Developers Need a Better Answer Now

All-electric mandates are expanding across New England and the Mid-Atlantic. Developers want a credible infrastructure solution that doesn't add construction complexity or cost volatility.

The Solution

Shared Ground.
Shared Savings.
Built Once.

Burbas installs a single underground thermal exchange network beneath a residential development. Every home connects to the shared loop — no individual ground boring, no gas lines, no combustion. Burbas operates the infrastructure. Homeowners pay a monthly subscription typically 40–55% lower than legacy gas and electric systems combined.

Phase One

Install the Loop

A single underground thermal exchange network is installed beneath or alongside a residential development. One bore field. One loop. Serving every unit on the site.

Phase Two

Connect Every Home

Each unit connects via a compact heat pump module — no individual ground boring, no gas lines, no combustion equipment. Mechanical rooms shrink. Maintenance liability disappears.

Phase Three

Operate as a Service

Burbas owns and operates the infrastructure under a long-term agreement. Homeowners pay a monthly subscription — typically 40–55% below legacy gas and electric systems.

60%

Lower Installation Cost

vs. individual ground-source heat pumps. Shared bore field, shared mechanical, shared commissioning — costs that individual installs can never achieve.

20yr

Average Contract Length

Developer-friendly model: Burbas owns and operates the loop. Developers avoid long-term maintenance liability while delivering a material all-electric advantage to buyers.

DR+

Grid Demand Response

Thermal mass of the ground loop smooths demand spikes. Burbas participates in utility DR programs, creating a revenue layer individual heat pumps cannot access.

Market Opportunity

A $200 Billion Infrastructure Replacement Market.
No One Has Built the Right Model — Until Now.

Near-Term · 0–5 Years

New Construction

  • 2.1M new housing units permitted annually in the U.S., with growing all-electric mandate coverage in target markets
  • Target: developers building 50+ unit residential projects in New England, Mid-Atlantic, and Great Lakes regions
  • SAM: ~18,000 qualifying projects over 5 years at $800K–$2.5M per project
  • Three active RFPs in pipeline for projects totaling 1,100 units

Long-Term · 5–15 Years

The Retrofit Opportunity

  • 60M existing U.S. homes on natural gas — the retrofit opportunity at neighborhood scale is unaddressed by every current player
  • Municipal and utility partnership model unlocks public housing, HOA districts, and utility-owned geothermal networks
  • Platform play: Burbas-operated networks as distributed thermal assets in grid markets
  • Policy tailwinds creating municipal funding pathways for affordable housing stock conversion
Business Model

Infrastructure Economics.
Utility Revenue.

Revenue

Multiple Streams, Recurring by Design

Homeowner subscriptions ($55–$95/month) + developer infrastructure fees + utility demand response payments. Every stream compounds as the network grows.

Payback in Under 5 Years

Avg. installation cost: $4,200/home net of 30% ITC. $72/month average subscription. Payback before Year 5 of a 20-year contract.

Defensibility

Permanent Infrastructure

Once installed, the loop stays forever. Switching costs are near-zero for Burbas to retain and near-prohibitive for competitors to displace. 20-year contracts from Year 1.

Why Now

The Window Is Open.
The Infrastructure Layer Hasn't Been Built.

Policy Momentum

IRA geothermal tax credits (30% ITC), expanding state-level electrification mandates, and utility decarbonization targets are creating developer pressure and municipal funding availability simultaneously — for the first time.

Competitive Vacuum

No scaled operator exists in the neighborhood-loop segment. Dandelion and Gradient operate at single-home scale. The closest competitor has weaker unit economics and no municipal pipeline. The position is open.

Cost Curve Inflection

Ground-loop installation costs have dropped 34% over 5 years. Heat pump module costs continue declining. Unit economics that were marginal at seed are compelling at scale — and the curve continues down.
