Heat Pump Payback in New Ulm, MN
Should New Ulm switch to a heat pump?
In New Ulm, a heat pump would cost more to run each year than what you have now. $5,500 is what New Ulm would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $268 a year here, so the extra spend stays unrecovered. That's New Ulm's own climate and rates talking, not a hedge or a caveat.

How cold New Ulm actually gets
New Ulm has a cold winter that leans hard on heating equipment, 6541 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 499 cooling degree days. Sizing runs off the design temperature, not the average day: -9.4°F here (coldest 2024 reading -14.8°F), which works out to a seasonal COP of 2.47 for the cold-climate class of unit this climate calls for. New Ulm needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

New Ulm's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 6,706 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,117 a year. That compares with roughly 68 Mcf a year of gas at New Ulm's $10.98 per-Mcf rate, about $849 a year with the old AC included, against a local electricity rate of 15.67¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $9,522 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive New Ulm's result is to prices
For the verdict in New Ulm to flip, electricity would need to drop to about 11.5¢/kWh from 15.67¢, or gas climb past $14.92 per Mcf from $10.98. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in New Ulm; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in New Ulm, compared
Gas isn't universal in New Ulm, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Switching saves about $1,579 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6.3 years.
New Ulm against the rest of the country
Ranked against the other 3206 cities covered, New Ulm comes in at 85 for heating severity, 1 would be the coldest place in the dataset, and 2516 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in New Ulm
New Ulm, Minnesota is home to about 13,970 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In New Ulm, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page, the 2.47 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. New Ulm's -9.4°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
