AIR SOURCE HEAT PUMPS DO NOT ECONOMICALLY DISPLACE FOSSIL FUEL BTUs IN COLD CLIMATES
https://www.windtaskforce.org/profiles/blogs/air-source-heat-pumps-...
As a result of a few years of complaints by various HP users, mainly about energy cost savings being much less than stated on the RE websites of Efficiency Vermont, GMP, VPIRG, etc., VT-DPS was ordered by the Vermont Legislature to hire a consultant to perform a survey.
CADMUS gathered the operating data of 77 HPs at 65 sites, to determine annual energy cost savings of the heat pumps.
Here are the results:
HPs Have Annual Owning and Operating Loss
- The annual energy cost savings were, on average, $200/y/HP
- The annual testing/cleaning costs were about $200/y/HP; any spare parts and installation labor are ignored
- The annual amortizing costs were $455.68; turnkey cost of a single head HP, $4500 at 6%/y for 15 years
- A loss of at least $455/y
Displaced Fossil Btus by Electricity Btus is Minimal
- On average, Vermont HPs provided 27.6% of the annual space heat, and traditional fuels provided 72.4%.
These numbers are directly from the CADMUS report.
CO2 Reduction per HP is Minimal
The small percentage of displaced fossil Btus indicates HPs would not be effective CO2 reducers in the cold climate of Vermont, if used in average VT houses.
From CADMUS Report:
Figure 14 of below URL would have shown increasing electricity consumption by HPs, with decreasing outdoor temperatures
However, figure 14 actually shows decreasing consumption by HPs at 28F and below, because fewer and fewer Owners were using their HPs, as temperatures decreased below 28F.
Figure 14 shows, Owners started to turn off their HPs at about 28F to 30F, because their past experience showed significant increases in electricity bills, if they ran their HPs low temperatures
The inescapable rule of physics is, the lower the outdoor temperature, the lower the efficiency of the HP.
A house requires the most heat, Btu/h, at, say 0F, whereas HPs would be least efficient
This would almost be like electric resistance heating, which would be great for GMPs profits, but disastrous for Owner’s financial well-being.
- At those low temperatures, the hourly cost of HPs exceeds the hourly cost of a traditional heating system.
- This statement is true for average Vermont free-standing houses
https://publicservice.vermont.gov/sites/dps/files/documents/Evaluat...
From CADMUS report:
- On average, an HP consumed 2,085 kWh during the heating season, of which:
1) Outdoor unit (compressor, outdoor fan, controls) + indoor air handling unit (fan and supplemental electric heater, if used), to provide space heat, 1880 kWh;
2) Standby mode, 76 kWh, or 100 x 76/2085 = 3.6%;
3) Defrost mode, 129 kWh, or 100 x 129/2085 = 6.2%. Defrost starts at about 37F and ends at about 10F.
On average, these houses were highly unsuitable for HPs, and the owners were losing money.

Displaced Fuel Percentage of Vermont Heat Pumps, based on CADMUS Report
As a result of a few years of complaints by various HP users, mainly about energy cost savings being much less than stated on the RE websites of Efficiency Vermont, GMP, VPIRG, etc., VT-DPS was ordered by the Vermont Legislature to hire a consultant to perform a survey.
CADMUS calculated:
- Space heat to all sites was 65 x 92 million Btu/site = 5,980 million Btu from all fuels. See page 22 of CADMUS report
- Heat from HPs was 77 x 21.4 million Btu/HP = 1,648 million Btu. See page 21 of CADMUS report
- Traditional systems provided 5980 – 1648 = 4,332 million Btu, or 4332/5980 = 72.4% of the total space heat.
- HPs provided 27.6% of the total space heat.
- The average COP was about 3.34
https://publicservice.vermont.gov/sites/dps/files/documents/Evaluat...
This proves HPs, in average VT houses, are an expensive, non-solution regarding: 1) reducing CO2, 2) fighting climate change, and 3) saving the world.
Such "non-solutions" are the inevitable result of self-serving, subsidy-seeking, RE businesses working together with career RE bureaucrats, behind closed doors
The energy cost savings were an average of about $200/HP per year, instead of the $1,200/y to $1,800/y bandied about by RE folks and Efficiency Vermont, GMP, VPIRG, VT-DPS, VEIC, etc.
After the CADMUS report, those estimates disappeared from the websites.
All the data in Table 1 are from the CADMUS report.

HEAT PUMPS ARE MONEY LOSERS IN MY VERMONT HOUSE, AS THEY ARE IN ALMOST ALL NEW ENGLAND HOUSES
https://www.windtaskforce.org/profiles/blogs/heat-pumps-are-money-l...
I installed three heat pumps by Mitsubishi, rated 24,000 Btu/h at 47F, Model MXZ-2C24NAHZ2, each with 2 heads, each with remote control; 2 in the living room, 1 in the kitchen, and 1 in each of 3 bedrooms.
The HPs have DC variable-speed, motor-driven compressors and fans, which improves the efficiency of low-temperature operation.
The HPs last about 15 years.
Turnkey capital cost was $24,000, less $2,400 subsidy from GMP
http://www.windtaskforce.org/profiles/blogs/vermont-co2-reduction-o...
My Well-Sealed, Well-Insulated House
The HPs are used for heating and cooling my 35-y-old, 3,600 sq ft, well-sealed/well-insulated house.
The basement, 1,200 sq ft, has a near-steady temperature throughout the year, because it has 2” of blueboard, R-10, on the outside of the concrete foundation and under the basement slab, which has saved me many thousands of space heating dollars over the 35 years.
I do not operate my HPs below 10F to 15F (depending on sun and wind conditions), because all HPs would become increasingly less efficient with decreasing outdoor temperatures.
The HP operating cost per hour would become greater than of my efficient propane furnace. See table 3
High Electricity Prices
Vermont forcing, with subsidies and/or GWSA mandates, the build-outs of expensive RE electricity systems, such as wind, solar, batteries, etc., would be counter-productive, because it would:
1) Increase already-high electric rates and
2) Worsen the already-poor economics of HPs (and of EVs)!!
https://www.windtaskforce.org/profiles/blogs/high-costs-of-wind-sol...
My Energy Cost Reduction is Minimal
- HP electricity consumption was from my electric bills, and an HP system electric meter.
- Vermont electricity prices, including taxes, fees and surcharges, are assumed at 20 c/kWh.
- My HPs provide space heat to 2,300 sq ft, about the same area as an average Vermont house
- Two small propane heaters (electricity not required) provide space heat to my 1,300 sq ft basement
- I operate my HPs at temperatures of 10 to 15F and greater (depending on wind and sun conditions)
- I operate my traditional propane system at temperatures of 10f to 15F and less
- My average HP coefficient of performance, COP, was 2.64
- My HPs required 2,489 kWh to replace 35% of my fossil Btus.
- My HPs would require 8,997 kWh, to replace 100% of my fossil Btus.
https://afdc.energy.gov/files/u/publication/fuel_comparison_chart.pdf
https://www.nature.com/articles/s41597-019-0199-y
https://acrpc.org/wp-content/uploads/2021/04/HeatPumps-ACRPC-5_20.pdf
Before HPs: I used 100 gal for domestic hot water + 250 gal for 2 stoves in basement + 850 gal for Viessmann furnace, for a total propane of 1,200 gal/y
After HPs: I used 100 gal for DHW + 250 gal for 2 stoves in basement + 550 gal for Viessmann furnace + 2,489 kWh of electricity.
My propane cost reduction for space heating was 850 - 550 = 300 gallon/y, at a cost of $2.339/gal (buyers plan) = $702/y
My displaced fossil Btus was 100 x (1 - 550/850) = 35%, which is better than the Vermont average of 27.6%
My purchased electricity cost increase was 2,489 kWh x 20 c/kWh = $498/y
My energy cost savings due to the HPs were 702 - 498 = $204/y, on an investment of $24,000!!
Amortizing Heat Pumps
Amortizing the 24000 – 2400 = $21,600 turnkey capital cost at 6%/y for 15 years costs about $2,187/y.
This is in addition to the amortizing of my existing propane system. I am losing money.
https://www.myamortizationchart.com
Other Annual Costs
There likely would be annual cleaning of HPs at $200/HP, and parts and labor, as the years go by.
This is in addition to the annual service calls and parts for my existing propane system. I am losing more money.
My Energy Savings of Propane versus HPs
Site Energy Basis: RE folks claim there would be a major energy reduction, due to using HPs. They compare the thermal Btus of 300 gallon of propane x 84,250 Btu/gal = 25,275,000 Btu vs the electrical Btus of 2,489 kWh of electricity x 3,412 Btu/kWh = 8,492,469 Btu. However, that comparison would equate thermal Btus with electrical Btus, which all ethical engineers know is an absolute no-no.
A-to-Z Energy Basis: A proper comparison would be thermal Btus of propane vs thermal Btus fed to power plants, i.e., 25,275,000 Btu vs 23,312,490 Btu, i.e., a minor energy reduction. See table 1A
BTW, almost all RE folks who claim a major energy reduction from HPs, do not know how to compose this table, and yet they mandate others what to do to save the world from Climate Change.

Comparison of CO2 Reduction in my House versus EAN Estimate
My CO2 emissions for space heating, before HPs, were 850 gal/y x 12.7 lb CO2/gal, from combustion = 4.897 Mt/y
My CO2 emissions for space heating, after HPs, were calculated in two ways:
1) Market based, based on commercial contracts, aka power purchase agreements, PPAs
2) Location based, based on fuels combusted by power plants connected to the NE grid
See Appendix for details.
Market Based
Per state mandates, utilities have PPAs with Owners of low-CO2 power sources, such as wind, solar, nuclear, hydro, and biomass, in-state and out-of-state.
Utilities crow about being “low-CO2”, or “zero-CO2” by signing PPA papers, i.e., without spending a dime.
Energy Action Network, a pro-RE-umbrella organization, uses 33.9 g CO2/kWh (calculated by VT-DPS), based on utilities having PPAs with low-CO2 power sources.
Using that low CO2 value makes HPs look extra good compared with fossil fuels.
My CO2 of propane was 550 gal/y x 12.7 lb CO2/gal, combustion only = 3.168 Mt/y
My CO2 of electricity was 2,489 kWh x 33.9 g/kWh = 0.084 Mt/y
Total CO2 = 3.168 + 0.084 = 3.253 Mt/y
CO2 reduction is 4.897 - 3.253 = 1.644 Mt/y, based on the 2018 VT-DPS “paper-based” value of 33.9 g CO2/kWh
Location Based
Utilities physically draw almost all of their electricity supply from the high-voltage grid
If utilities did not have PPAs, and would draw electricity from the high-voltage grid, they would be stealing.
ISO-NE administers a settlement system, to ensure utilities pay owners per PPA contract.
Electricity travels as electric-magnetic waves, at near the speed of light, i.e., from northern Maine to southern Florida, about 1,800 miles in 0.01 second.
There is no physical basis for lay RE folks to talk about there being a “VT CO2” or a “NH CO2”, etc.
All electricity on the NE grid has one value for g CO2/kWh.
ISO-NE, the NE grid operator, calculated that value at 317 g CO2/kWh, at wall outlet, for 2018
My CO2 of propane was 550 gal/y x 12.7 lb CO2/gal, combustion only = 3.168 Mt/y
My CO2 of electricity was 2,489 kWh x 317 g/kWh = 0.789 Mt/y
Total CO2 = 3.168 + 0.789 = 3.937 Mt/y
CO2 reduction is 4.897 - 3.937 = 0.939 Mt/y, based on the 2018 “real world” value of 317 g CO2/kWh, as calculated by ISO-NE
Cost of CO2 Reduction is ($2059/y, amortizing - $204/y, energy cost savings + $200/y, service, parts, labor) / (0.939 Mt/y, CO2 reduction) = $2,188/Mt, which is outrageously expensive.
https://www.eia.gov/environment/emissions/co2_vol_mass.php
https://afdc.energy.gov/files/u/publication/fuel_comparison_chart.pdf
EAN Excessive CO2 Reduction Claim to Hype HPs
EAN claims 90,000 HPs, by 2025, would reduce 0.37 million metric ton of CO2, in 2025, or 0.37 million/90,000 = 4.111 Mt/y.
https://www.eanvt.org/wp-content/uploads/2020/03/EAN-report-2020-fi...
.
EAN achieves such a high value, because EAN assumes 100% displacement of fuel (gas, propane, fuel oil), which is completely unrealistic, because the actual fuel displacement in Vermont houses with HPs was only 27.6%, based on a VT-DPS-sponsored survey of HPs in Vermont, and 35% in my well-insulated/well-sealed VT house, as above stated.
The EAN 100% claim would be true, only for highly sealed and highly insulated houses, which represent about 2% of all Vermont houses.
In addition, the average Vermont house would need 2 to 3 HPs, with 4 to 6 heads, at a turnkey cost of at least $20,000, to achieve 100% displacement. See URL

Coddling RE Businesses
Heavily subsidized businesses selling/installing/servicing HPs, etc., will be collecting hundreds of $millions each year over the decades, while already-struggling, over-regulated, over-taxed Vermonters will be further screwed out of a decent standard of living.
HP boosters Sens. Bray, McDonald, etc., know about those dreadful HP results in Vermont, and yet they continue shilling for HPs.
All these expensive Vermont GWSA efforts will be having ZERO IMPACT ON GLOBAL WARMING.
APPENDIX 1
Statewide Building Code
Vermont needs an enforced building code for all new and deeply retrofitted buildings. The code would include R-40 walls, R-60 roofs, R-20 basements, R-10 doors, R-7 triple-pane windows, air-to-air heat recovery systems, highly sealed and highly insulated, and arranged for high levels of passive solar.
Such buildings would use about 1/3 of the energy of existing Vermont buildings
With ground source HPs, they would yield a much better CO2 reduction than is possible with air source HPs.
APPENDIX 2
Ground Source HPs for 100% Fossil Fuel Displacement
To achieve significant reductions of annual energy use by buildings for heating, cooling and electricity, you have to:
1) First build buildings, or deeply retrofit buildings, according to the above proposed building code; “weatherizing” is just a band-aid
2) Then you install ground source HPs, to economically displace 100% of fossil fuels.
Ground source HPs are efficient on a year-round basis, even when it is minus 30F outside.
My brother, living about one hour north of Oslo, Norway, has ground source HPs in his house.
It is typically done in Denmark, Norway, Sweden, Finland, etc.
Their electric grid has a very low CO2/kWh, because of nuclear, hydro and wind (mostly Denmark)
It is a rational, engineering approach.
Vermont Governor Scott talking about “leaning towards approval of a modified CHS” is unwise.
It is a fool’s errand, a feel-good, political approach.
It has nothing to do with common engineering sense.

By the way, all of this, including rolling blackouts at ZUB-ZERO temperatures, and a lack of gas and oil for space heating, applies to New England, if:
1) New York State keeps obstructing new gas pipelines from Pennsylvania to New England; THIS SHOULD BE LEGALLY FORBIDDEN AS AN UNCONSTITUTIONAL INTERFERENCE OF INTER-STATE COMMERCE, and
2) The New England oil, gas and coal storage capacities near power plants are not increased by at least 100% to ensure RELIABLE ELECTRICAL SERVICE IN WINTER, WHICH WOULD BE ESPECIALLY IMPORTANT, IF UNCERTAIN, MOTHER-NATURE, WEATHER-DEPENDENT WIND AND SOLAR WERE FURTHER EXPANDED, AS THE US AIMS TO BLINDLY COPY THAT DISASTROUS EUROPEAN SCENARIO

APPENDIX 3
Satellites and balloons measure temperatures of the Troposphere, which starts at ground level, and has an average height of 59,000 ft at the tropics, 56,000 ft at the middle latitudes, and 20,000 ft at the poles. Above those levels starts the Stratosphere.
Balloons directly measure temperatures. Satellites measure radiation, from which temperatures are calculated.
Both consistently measure much lower temperatures than the average of 102 computer-generated graphs.
See Appendix 2 and 3
The data in the below images is for a 43-y period.
There is global warming, but it is not anywhere near as much as scare-mongers are claiming.
https://www.windtaskforce.org/profiles/blogs/grid-scale-battery-sys...
1) Objective satellite and balloon temperatures increased from 0.00 to 0.5 C, or, or 0.116 C/decade
2) Subjective computer-generated temperatures increased from 0.00 to 1.20 C; or 0.28 C/decade, about 2.7 TIMES AS FAST
The temperature data by satellites and balloons are more accurate than land-based measurements.
See Appendix 2 and URL
https://en.wikipedia.org/wiki/UAH_satellite_temperature_dataset
Satellite measurements are made many times during every day and systematically cover almost the entire world; +/- 85-degree latitude.
The satellite data is vastly more complete, and accurate than would be gathered by ground stations. (See Appendix 2)
Balloon measurements, made on a sampling basis, are vastly less complete than satellite measurements, but they serve as a useful crosscheck on the satellite measurements.
NOTE: Behind the 102 computer graphs are hundreds of organizations that likely receive a significant part of their revenues from governments and subsidy-receiving wind, solar, battery, etc., businesses.
The livelihood and career prospects of the people creating these graphs is more secure, if they aim high, rather than low.

APPENDIX 4
Science and Environmental Policy Project (SEPP) and also a member of the CO2 Coalition. Sheahen and the Coalition are collaborating on a brief.
SEPP’s October 8 newsletter contains a summary of a major 2021 paper by Happer and co-author William van Wijngaarden that completely undermines the fake “science” the IPCC and EPA used to support the case of climate alarm.
Sheahen specifically discusses the efforts of Professors William van Wijngaarden and William Happer in their pioneering work in calculating the real-world Global Warming Potentials (GWPs) of the five most common Green-House Gases (GHGs).
Sheahan explains why the approach used by IPCC is faulty, but nonetheless used by its followers, such as the US National Center for Atmospheric Research (NCAR) and the EPA.
These faulty methods lead to great exaggeration of the greenhouse effect of carbon dioxide, methane, and other minor greenhouse gases. . . .
Sheahan shows the stunning agreement between the calculations of van Wijngaarden and Happer (W & H) with satellite measurements (and balloon measurements) of outgoing infrared radiation emitted by the earth to space . . .
Sheahan claims, because of the exceptionally good agreement between observational data and the calculations of W & H, we can conclude the W&H model has been validated.
The W&H model embodies the scientific method.
In that case, it is reasonable to use it to study other hypothetical cases.
It is not possible to do so with IPCC models, which have never achieved agreement with observations. . .
See Appendix 3
The gist of the H&W work is the greenhouse effect of CO2 in the atmosphere is almost entirely saturated, such that any additional CO2 can have almost no additional warming effect.
Here is a chart prepared by Sheahan to illustrate the H&W results.
As atmospheric CO2 increases, say from 380 to 420 ppm, it has less warming effect.
The most warming effect occurs at very low levels of CO2, say 20 to 60 ppm.
APPENDIX 5
A timely and important new paper has just been uploaded to the CO2 Coalition website on nitrogen.
The first half of the paper on the greenhouse warming effect of N2O is quite technical
It is summarized in the first link.
Link to the full paper is at the bottom. Please distribute widely.

Nitrous Oxide and Climate – Why restricting N2O emissions is unnece...
Nitrous oxide (N20) has now joined carbon dioxide (CO2) and methane (CH4) in the pantheon of “human-generated demon” gases.
GW scare-mongers view increasing concentrations of these molecules are leading to unusual and unprecedented GW, which will lead to catastrophic consequences for both our ecosystems and humanity.
Countries around the world are in the process of greatly reducing, or eliminating, the use of nitrogen fertilizers, based on heretofore poorly understood properties of nitrous oxide.
Reductions of N2O emissions of 40 to 45 percent are being proposed in Canada , and by up to 50 percent in the Netherlands .
Sri Lanka’s complete ban on fertilizer in 2021 led to the total collapse of their primarily agricultural economy.
The CO2 Coalition has published this paper, which evaluates the GW effect of the N20 and its role in the nitrogen cycle.
Policymakers can now proceed to make informed decisions about the costs and benefits of mandated N20 reductions of this beneficial molecule.
This new paper joins previous CO2 Coalition reports on other greenhouse gases, carbon dioxide and methane.
Key takeaways from the paper:
- At current rates, a doubling of N2O would occur in more than 400 years.
- Atmospheric warming by N2O is estimated to be 0.064 C per century.
- Increasing crop production requires continued application of synthetic nitrogen fertilizer to feed a growing population.
