Statements from this episode (14)
Kann: Modern heat pumps deliver coefficients of performance between 3 and 5
“Heat pumps today have coefficients of performance anywhere from, say, three to upwards of five for really good ones. In other words, you put one kilowatt in, you get three to five out.”
Kann: Nearly half of South Carolina homes already use heat pumps
“So in South Carolina, for example, nearly 50% of homes already have them, but in most of the country, and particularly in colder climates, the penetration is a fraction of that.”
Kann: EIP invested in industrial heat pumps and seeks residential deals
“We've already made one investment focused on heat pumps for industrial use, more on that soon, but we're hungry to find more, particularly on the residential side.”
Lubershain: Air conditioning is among fastest growing sources of electricity demand globally
“Air conditioning demand is one of, if not the absolute fastest growing sources of electricity demand globally and is predicted to continue to be so for decades to come.”
Lubershain: Global AC demand will add another US power sector by 2050
“Depending on what forecast you look at in a sort of business as usual technology scenario, that means we're on track to add, roughly speaking, another whole U.S. Electricity sector worth of electricity demand globally for this new air conditioning demand by ar…”
Lubershain: Medium heat pumps achieve 3.0 COP at freezing temperatures
“A medium performance heat pump today when the temperature is around freezing, you know, 32 degrees Fahrenheit, you're probably getting around a coefficient of performance of three when the temperatures, you know, if you're just trying to heat a home. So, you k…”
Lubershain: Heat pump coefficient of performance drops to 1 at -5°F
“By the time you get to around, you know, negative five, -10 degrees, certainly anywhere below that, with almost any heat pump on the market A, that heat pump loses some of its Capacity. So you need a bigger heat pump that starts with higher capacity in order t…”
Lubershain: Midwest heat pump adoption rose from 5% to 20%
“Back in 2000, you know, at the turn of the century, heat pump adoption, you know, in or, you know, for new, new heating systems in, say, the U.S. Midwest, relatively cold climate area, was at about five percent. And by the late aughts, you know, 2009, 20 10, i…”
Lubershain: Heat pumps comprise 40% of new US heating and cooling installations
“Overall, across the U.S., it's around 40%, but that's predominantly because of another sort of magical property of heat pumps, which is that the same system can be used bidirectionally if it's designed appropriately, which means that you can use one heat pump …”
Kann: Bending the heat pump adoption curve requires vertically integrated businesses
“For any one player, any one company to single-handedly bend the curve on heat pump adoption, it sort of has to be a vertically integrated solution of some kind or another”
Lubershain: Affordable cold-temperature efficiency is the key unlock for heat pumps
“Higher efficiency, particularly at cold temperatures, is really the key if you can do it without significantly adding to the cost of the unit.”
Lubershain: Deep cold heat pumps add peak load equal to two EVs
“Roughly speaking for a typical U.S. Household, it means adding new peak load to that home that's equivalent to about, ah, two electric vehicles that are plugged into level two chargers, ah, during those cold periods.”
Lubershain: Electrifying heat could triple cold-climate peak electricity demand
“And so what this might do in cold climate environments is, is Basically shift peak demand from the summer to the winter and increase the peak by about three X.”
Lubershain: Heat pump investor admits he heats his own home with oil
“I have oil heat in my home, unfortunately, which I'm really embarrassed to say, but that's, like, due to idiosyncratic reasons about the house, and we only moved in two years ago, and I have this big plan to trick this thing out, like, completely when it comes…”
