Group-buys of heat pumps can encourage homeowners to make the switch from traditional gas furnaces, which are large contributors to greenhouse gas emissions, by offsetting the high upfront cost. Shreyas Sudhakar, founder and CEO of heat pump installment company Vayu, also comments on both the technical efficiency and sustainability benefits of the shift to heat pumps.
Traditional heating and cooling systems are the largest sources of emissions in a home. Heat pumps have lower carbon emissions than any other home heating system and can even be carbon neutral when run by renewable energy sources, like solar panels. They are also safer, more efficient, and cheaper in the long run. What keeps many homeowners from installing them, despite the benefits, is the high upfront costs. Heat pump group-buy programs can help with that.
Heat pumps work in a similar way to refrigerators and air conditioners. They extract heat from the air, ground, water, or from waste heat generated by factories or data centers and amplify it. Then, this heat is moved into the home with the help of a liquid called a refrigerant. The refrigerant changes from liquid to gas and back again, transferring heat throughout the process. When the refrigerant changes from liquid to gas, it absorbs heat, and when changed back to liquid it releases the heat. Then, the heat is delivered throughout the home through forced air or via a hydronic system (using water, steam, or glycol solution as a medium for heat transfer).
This way of transferring heat allows heat pumps to be more efficient than other heating technologies, like boilers or electric heaters. The energy output of a heat pump is typically 4 times greater than the electrical energy used to run it. This can be up to 5 times more energy efficient than gas boilers.
Installing a heat pump has a high upfront cost but group-buy programs can help make it more budget-friendly. To participate, homeowners fill out an interest form through a coordinator like Heat Pumped. Interested households are then grouped together by region and offered a deal that can save each household $3000 to $6000 dollars. This deal works similar to Costco, where installers can negotiate discounts from manufacturers on equipment due to buying and installing in bulk.
Since heat pumps are more energy efficient than conventional heating systems, heat pumps can reduce homeowner’s energy bills and stay unaffected by price increases from extreme weather or high energy demand. On average, homeowners in the US can save $370 per year by switching to a heat pump, or up to $1000 per year when switching from an especially inefficient heat system, like those run on oil or propane.
Heat pumps don’t only heat, they can also cool, and they can replace not only heaters but also traditional air conditioners. They also have more temperature control and allow each room in the home to be heated or cooled individually. Heat pumps don’t require the combustion of fossil fuels or carbon monoxide emissions, like other heating sources, making them safer. Furthermore, despite the common myth, heat pumps are effective even at very cold temperatures, working well at temperatures as low as -20° Fahrenheit.
Installing heat pumps is a difficult project and requires more planning and preparation than traditional boiler installations. Detailed calculations and a thorough analysis of the property need to be conducted to understand the property’s insulation abilities, as well as its heating and cooling requirements. Space can also be a challenge. Smaller properties or apartments might not be able to fit heat pump systems. Additionally, ground and water-source heat pumps require large outdoor areas or nearby water sources like ponds, rivers, or lakes. There are also a variety of refrigerants that can be used and some of them can be harmful to the environment. Luckily, biodegradable fluid options are available.
Although group-buy programs are an excellent way to save money, they sometimes require a household to have to wait until a group is formed and a discount can be applied before installing the heat pump. So, group-buy programs are not ideal for homeowners who need their heating systems upgraded quickly.
Shreyas Sudhakar believes that heat pumps have the potential to greatly decrease our carbon foot-prints. Sudhakar also believes that group-buy programs are important for encouraging households to make the environmentally-friendly switch to heat pumps. Those unsure about the cost of heat pump installation can be persuaded by the thousands of dollars they save through a group-buy program. Group-buy participants can also spread the word about their new heating system, encouraging more households to join in on the savings and install lower emission heating systems.
Shreyas Sudhakar, a former rocket propulsion engineer, is the founder and CEO of Vayu, a heat pump installation company in the Bay Area. With his company, he hopes to improve the heat pump installation process for homeowners through transparency with customers, honest recommendations, and expert installers that take the time to understand the needs of each individual home.

Ethan: I’m Ethan Elkind, and you’re listening to Climate Break– climate solutions in a hurry. Today’s proposal? Replacing polluting fossil gas furnaces with heat pumps by lowering their cost through group buy programs. We spoke to Shreyas Sudhakar, Founder and CEO of heat pump installation company Vayu.
Shreyas: The brilliant thing about this is a heat pump is that it moves energy rather than creating it. With a gas furnace, for one unit of energy, you get maybe .8 units of energy into your house. With a heat pump, for one unit of energy, you get four units of energy. And so they’re much more efficient, they’re better for the climate, they’re healthier, all sorts of things.
Ethan: Heating our homes with gas furnaces is a major source of greenhouse gas emissions and can contribute to indoor air pollution. But switching to a heat pump can be expensive. Sudhakar says a group-buy program can lower the upfront cost for homeowners by pooling demand.
Shreyas: The benefit of a group-buy is that the extra savings flips the switch from someone being on the fence to it being a great opportunity and making sense for them now to do this today. People save between three to six thousand dollars on their heat pump installation by participating in their group buy. A lot of our group buy participants then talk about this to their friends, to their neighbors, and so that right there is market transformation.
Ethan: Beyond saving homeowners money, Sudhakar believes heat pump group-buys will have a lasting impact.
Shreyas: Every single furnace that we rip out is another bit of carbon emissions that is gone forever. And once that homeowner switches to a heat pump, that house is gonna be on a heat pump and it’s not gonna have that carbon footprint.
