When installers bundle many household orders into a single heat pump purchase, they can cut equipment costs by 15 to 30 percent, according to WIRED. In California, the first state-level group-buy program demonstrates how demand aggregation lowers unit prices and builds a queue of installation work — a model directly relevant to procurement teams buying distributed energy equipment.
California's first heat pump group-buy
Heat waves in California this summer pushed Shreyas Sudhakar, founder and chief executive officer of heat pump installation firm Vayu, to market a group-buy scheme online, according to WIRED. Just 54 percent of homes in the state have central air-conditioning, and rising temperatures make cooling a growing necessity. Sudhakar saw the hot weather as an opportunity to sign up multiple households for heat pumps at a discount.
The program, launched last year with heat pump marketplace VoltHub as the first California Heat Pump Group Buy, is available around Los Angeles and the Bay Area. "Nobody, to our knowledge, had done it in California," Sudhakar told WIRED.
Quantified impact: equipment discounts and installed cost
The bulk-buy approach delivers measurable savings. Sudhakar told WIRED that his team shops for deals from distributors and seeks the best value for the whole group.
"We're looking for what is the best value across the entire group," Sudhakar said. "Typically, we're getting 15 to 30 percent discounts on the equipment."
Among the first roughly 10 customers in the initial cohort was Naoya Kanai, a data scientist in San Mateo. His 2,500-square-foot 1980s home received a new heat pump system for roughly $14,500, using ductwork that was already in place. Kanai told WIRED the program was "one of the most affordable ways to get a quality system," and that he signed up knowing that federal rebates for carbon-free appliances would soon disappear.
| Metric | Value |
|---|---|
| California homes with central AC | 54% |
| Typical equipment discount via group-buy | 15–30% |
| First group-buy cohort size | ~10 customers |
| Kanai's installed system cost | ~$14,500 |
| Kanai's home size | 2,500 sq ft |
How the group-buy model works
Air-source heat pumps run on electricity and transfer heat between indoors and outdoors, according to WIRED. Sudhakar, a former rocket propulsion engineer at Blue Origin, said: "At the end of the day, it's a bunch of pipes and a heat exchanger moving energy from one place to another."
Once households sign up, Vayu determines what equipment each installation requires, then negotiates with distributors to secure the best pricing for the entire group. For installers, the model creates a pipeline of confirmed jobs — converting fragmented, one-off projects into a scheduled sequence of work.
A decade of bulk buying on Gabriola Island
The group-buy concept has deeper roots in Canada, according to WIRED. On Gabriola Island, British Columbia — a 58-square-kilometer island home to about 4,500 people — Energy Gabriola set itself up in 2010 as a heat pump dealer via a distributor, enabling the group to buy heat pumps in bulk and sell them at cost.
With a largely volunteer workforce, the group has installed more than 1,000 heat pumps to date, electrifying nearly half of the island's households. "We think we're the heat pump capital of Canada," Steven Earle of Vancouver Island University told WIRED. Energy Gabriola had an advantage: there was no heat pump market or installation service on the island whatsoever before it began.
What this means for procurement teams
For procurement executives, the California and British Columbia cases illustrate how demand aggregation can lower unit costs without redesigning products. Vayu's group-buy negotiated 15–30 percent equipment discounts by committing multiple installations to distributors; Energy Gabriola achieved similar scale by acting as its own dealer.
The model also addresses installer economics by replacing one-off projects with queued, confirmed work, which can improve labor productivity and reduce scheduling risk. With federal rebates for carbon-free appliances disappearing — a factor Kanai cited in his decision — group-buy pricing may become a primary cost lever for electrification projects. Procurement teams should watch whether such programs expand beyond California and British Columbia, and whether similar aggregation tactics can be applied to other high-cost equipment categories.
