Thinking About Upgrading Your Heating System? A Westchester Homeowner’s Guide to Boilers, Heat Pumps, Geothermal & More

By Thomas Roberts, William Raveis Real Estate

After the cold and snowy winter of 2026, many homeowners in Westchester County and throughout New York are taking a serious look at their heating systems. Between January and February blizzards, whiteout conditions, freezing temperatures, and rising fuel costs, older boilers, furnaces, and hot water systems are getting more attention.

As a Westchester Realtor, one of the questions I hear from homeowners is whether a heating system upgrade can make a home more comfortable, more energy efficient, and potentially more appealing when it comes time to sell.

The answer depends on the home. The best system for one property may not be the best system for another. Your current fuel source, home size, insulation, ductwork, mechanical room space, electrical panel, budget, and long-term plans all matter.

This guide breaks down several heating options homeowners may want to research, including high-efficiency boilers, combi boilers, heat pumps, geothermal systems, heat pump water heaters, and wood pellet heating systems.

Watch: Heating Upgrade Overview

Here are several short videos I put together to help homeowners start thinking about heating upgrades, costs, comfort, and resale value.

Questions Every Homeowner Should Ask Before Upgrading

What Type of Heating System Do You Currently Have?

Before pricing out a new system, start with what you already have. Many homes in Westchester use one of the following:

Oil heat
Natural gas
Propane
Electric baseboard heat
Hot water radiators
Baseboard hydronic heat
Forced hot air
Radiant floor heating

A home with existing ductwork may be a better candidate for a ducted heat pump. A home with radiators may be better suited for a new boiler, combi boiler, or possibly an air-to-water heat pump system depending on the layout.

How Long Do You Plan to Stay in the Home?

If you plan to stay in the home for many years, a higher upfront investment may make sense if it lowers monthly energy costs and improves comfort. If you plan to sell soon, the question becomes different: will the upgrade improve marketability, reduce buyer objections, and help the home compete better?

Does Your Property Qualify for Certain Upgrades?

Some systems require more than just replacing equipment. Before upgrading, consider:

Yard space
Ductwork
Electrical panel capacity
Mechanical room space
Basement ceiling height
Fuel source availability
Insulation quality
Age and condition of windows and doors

A heating upgrade works best when the home itself is reasonably efficient. Poor insulation, drafty windows, and air leaks can reduce the benefit of even the best new heating system.

High-Efficiency Gas Boilers: A Popular Upgrade Choice

What Is a Condensing Boiler?

A condensing boiler is a high-efficiency boiler that captures extra heat from exhaust gases that older boilers allow to escape. Many modern condensing boilers can reach efficiency ratings in the 90% range when properly installed and matched to the home.

For homeowners replacing an older oil or gas boiler, this can be one of the most familiar and practical upgrades.

Popular Boiler Brands to Consider

Navien

Navien is commonly discussed by homeowners considering high-efficiency boilers and combi boiler systems. A combi boiler provides both space heating and domestic hot water from one unit.

Best fit: Smaller to medium-sized homes, homes with limited mechanical room space, and homes where the owner wants to combine heat and hot water in one system.

Pros:

Space-saving design
Can provide heating and hot water
Good option for some smaller homes

Cons:

May not be ideal for homes with very high hot water demand
Requires proper sizing
Annual maintenance is important

Lochinvar

Lochinvar is often viewed as a contractor-grade boiler brand and may be considered for larger homes, multi-zone systems, and homes with greater heating demand.

Best fit: Larger homes, homes with multiple heating zones, and homeowners looking for a more robust boiler system.

Munchkin

Munchkin boilers are older high-efficiency boilers that are still found in many Northeast homes. If you have a Munchkin boiler, the decision may be whether to repair the existing system or replace it with a newer high-efficiency boiler.

Rule of thumb: If repairs are becoming frequent, parts are harder to find, or the boiler is near the end of its useful life, replacement may be worth discussing with a licensed heating contractor.

Combi Boiler vs. Boiler Plus Indirect Hot Water Tank

A combi boiler can be a good option when space is limited and hot water needs are moderate. A boiler with an indirect hot water tank may be better for larger households or homes with multiple bathrooms.

System Type	Best For	Possible Drawback
Combi Boiler	Smaller homes, limited space, moderate hot water use	May struggle with high simultaneous hot water demand
Boiler + Indirect Tank	Larger homes, multiple bathrooms, higher hot water demand	Requires more space and may cost more upfront

Heat Pumps: One of the Fastest Growing Heating Options

What Is an Air-Source Heat Pump?

An air-source heat pump moves heat instead of creating heat by burning fuel. In the winter, it pulls heat from outdoor air and moves it inside. In the summer, it can work like air conditioning by moving heat out of the house.

Heat pumps can be installed as ductless mini-splits or as ducted systems.

Pros of Heat Pumps

Heating and cooling in one system
Can reduce fossil fuel use
Good for room-by-room comfort
May qualify for NYS incentives
Can be useful for homes with uneven temperatures

Cons of Heat Pumps

Installation cost can be significant
Cold-weather performance depends on equipment quality and sizing
Some homes may need electrical upgrades
Mini-split wall units may not appeal to every homeowner

Who Should Consider a Heat Pump?

Heat pumps may be worth researching if you have an oil-heated home, an older air conditioning system, uneven room temperatures, or a room addition that is difficult to heat and cool.

Geothermal Heating: The Long-Term Premium Option

What Is Geothermal?

Geothermal heating, also called a ground-source heat pump, uses the relatively stable temperature below the ground to heat and cool a home. It is one of the most efficient systems available, but it is also one of the most expensive to install.

Pros of Geothermal

Very efficient
Quiet operation
Long equipment lifespan
Can reduce long-term energy costs
May be attractive in higher-end homes

Cons of Geothermal

High upfront cost
Requires drilling or excavation
Not every property is suitable
More complex installation process

Does Your Property Have Enough Land?

Horizontal Loop Systems

Horizontal loop systems require more yard space because piping is buried in trenches. This may work better for larger properties.

Vertical Loop Systems

Vertical loop systems require drilling deeper wells. This may be more practical for suburban lots, but drilling can increase installation costs.

Is Geothermal Worth It?

Geothermal is usually best for long-term homeowners, larger homes, higher-end properties, and homes with large heating and cooling bills. It may not be the best choice for someone planning to sell in the near future unless the system clearly fits the home and market.

Heat Pump Water Heaters: An Overlooked Upgrade

How They Work

A heat pump water heater pulls heat from the surrounding air and uses it to heat water. These systems are often installed in basements, utility rooms, or garages with enough air space.

Pros

High efficiency
Can lower electric water heating costs
May help dehumidify basement air
May qualify for rebates or tax credits

Cons

Needs enough surrounding air space
Can have slower recovery than some traditional systems
May not be ideal for very small mechanical closets

Best Home Types

Heat pump water heaters can be a strong option for homes replacing older electric water heaters, especially where there is adequate basement or utility room space.

Wood Pellet Furnaces & Boilers: Are They Practical?

What Is a Pellet Heating System?

Wood pellet systems burn compressed wood pellets to create heat. These systems can include pellet stoves, pellet furnaces, and pellet boilers.

Popular Pellet Brands & Systems

Some homeowners researching pellet heat may come across brands and systems such as Breckwell, ComfortBilt, and Pellet Duo. Availability, service support, and installer experience can vary widely by area.

Costs to Expect

Pellet systems vary depending on whether the homeowner is installing a stove, furnace, or boiler. A simple pellet stove used for supplemental heat may cost far less than a whole-house pellet boiler system.

Pros of Pellet Systems

Renewable fuel source
Can be useful as backup or supplemental heat
May help some oil-heated homes reduce fuel use

Cons of Pellet Systems

Pellet storage is required
More hands-on maintenance
Ash removal is needed
Contractor availability may be limited
Less convenient than automatic gas, oil, or electric systems

Are Pellet Systems Practical in Suburban New York?

For many suburban Westchester homeowners, pellet systems may make more sense as supplemental heat rather than the primary heating system. They may be more practical in rural settings where fuel storage, maintenance, and space are less of an issue.

NYS Incentives, Rebates & Tax Credits

NYS Clean Heat Program

New York State and participating utilities offer programs that may help with heat pumps, geothermal systems, and heat pump water heaters. Homeowners should check current eligibility before making a decision.

Why Incentives Matter

Rebates and tax credits can help reduce upfront costs. This can improve the return on investment and make a higher-efficiency system more realistic for homeowners.

Cost Comparison: What Homeowners Can Expect to Spend

Actual costs vary based on home size, equipment, labor, electrical work, ductwork, chimney work, permits, and contractor pricing. The following table is a general planning guide only.

System	Typical Installed Cost Range	Efficiency	Maintenance	Best Fit	Expected Lifespan
High-Efficiency Gas Boiler	$8,000–$18,000+	High	Annual service	Homes with existing radiators or baseboard heat	15–25 years
Combi Boiler	$7,000–$16,000+	High	Annual service	Smaller homes needing heat and hot water	12–20 years
Air-Source Heat Pump	$10,000–$30,000+	High	Filter cleaning and periodic service	Homes needing heating and cooling	12–20 years
Geothermal	$30,000–$70,000+	Very high	Lower routine maintenance	Long-term owners and larger homes	20–25+ years for equipment; loops can last longer
Pellet Stove / Pellet System	$3,000–$20,000+	Moderate to high	Regular cleaning and ash removal	Supplemental heat or rural homes	10–20 years
Heat Pump Water Heater	$2,000–$5,500+	High	Filter cleaning and routine service	Homes replacing electric water heaters	10–15 years

Will a Heating Upgrade Increase Resale Value?

A heating system upgrade may help a home compete better, especially if the current system is old, inefficient, unreliable, or close to failure. Buyers often notice big-ticket items such as roofs, windows, boilers, furnaces, central air, hot water heaters, and electrical panels.

However, homeowners should be careful not to assume every upgrade creates a dollar-for-dollar increase in resale value. The value depends on the type of system, quality of installation, buyer expectations, age of the home, and local market conditions.

In many cases, the biggest real estate benefit is reducing buyer objections. A newer, efficient, well-maintained heating system can give buyers more confidence when reviewing a home.

Final Thoughts: Which Heating Upgrade Makes Sense for Your Home?

Small Home

A combi boiler, high-efficiency boiler, or ductless heat pump may be worth researching.

Larger Family Home

A boiler with an indirect hot water tank, larger heat pump system, or geothermal system may be more appropriate depending on the layout.

Oil-Heated Property

Heat pumps, geothermal, or a high-efficiency boiler conversion may be worth discussing with contractors.

Long-Term Owner

Geothermal, whole-house heat pumps, and major efficiency upgrades may make more sense if you plan to stay for many years.

Rural Homeowner

Pellet systems may be more practical where storage, maintenance, and fuel delivery are less of a concern.

Budget-Conscious Homeowner

Start with an energy audit, insulation, air sealing, and basic system maintenance. Sometimes the most cost-effective improvement is reducing heat loss before replacing equipment.

Before making a decision, speak with multiple licensed contractors and ask about rebates, energy audits, and total operating costs—not just installation price.

Thinking About Selling or Improving Your Westchester Home?
