Air-to-Water Heat Pumps (Heat Pump Boilers) for NH Homes
An air-to-water heat pump, sometimes called a heat pump boiler, moves heat from outdoor air into a hydronic system. It can be considered for some New Hampshire homes with radiant floors, fan coils, or other distribution designed for lower water temperatures. Existing fin-tube baseboard or radiators may need a detailed heat-loss and output review because heat-pump efficiency and capacity change with outdoor temperature and required water temperature. A.J. LeBlanc Heating evaluates the complete system before recommending the technology.
How an air-to-water heat pump works
An air-to-water heat pump transfers heat from outdoor air into water for a compatible hydronic system. Performance depends on outdoor temperature, required supply-water temperature, the selected equipment, and the home's load.
Backup and system design
Air-to-water systems may be designed with electric resistance, gas, propane, oil, or another compatible backup strategy. The right design depends on the selected equipment, the home's heating load, the water temperature required by the emitters, available electric capacity, energy rates, and the homeowner's priorities.
There is no single changeover temperature for every New Hampshire home. We use the equipment's published performance and the home's design conditions to determine whether backup is needed and when it should operate.
Manufacturer-certified installation
A.J. LeBlanc Heating is manufacturer-certified to install Viessmann, Mitsubishi, and Daikin air-to-water systems. We evaluate the home and select equipment based on current U.S. availability, application support, published performance, and the system design.
Existing hydronic systems
An existing hydronic system can be a starting point, but an air-to-water heat pump is not automatically a drop-in boiler replacement. Some piping, controls, and emitters may be reusable. The answer depends on their output at the proposed water temperature, the home's heat loss, flow requirements, buffer requirements, and backup design.
Radiant floors and low-temperature distribution
Radiant floors and other low-temperature hydronic systems are often worth evaluating because air-to-water heat pumps generally perform better at lower supply-water temperatures. We still confirm the home's load, required water temperature, flow, controls, and floor construction before recommending equipment.
Fin-tube baseboard and radiators
Fin-tube baseboard and radiators designed around hotter boiler water require a closer review. We compare the home's heat loss with the emitters' output at the proposed water temperature. The project may require added radiation, envelope improvements, supplemental heat, or a different system design.
Why work with A.J. LeBlanc Heating
A.J. LeBlanc Heating combines decades of hydronic experience with manufacturer certifications for installing Viessmann, Mitsubishi, and Daikin air-to-water systems. We explain the design requirements, backup options, and practical tradeoffs so homeowners can decide whether the technology is a good fit for the house and budget.
Air-to-water heat pumps give some New Hampshire homeowners a way to consider electrification while keeping hydronic distribution. The result depends on careful sizing, water-temperature requirements, equipment performance, controls, and backup design. That is why we evaluate the whole system before proposing the equipment.
Rebates
Rebates and eligibility change by program and equipment. During the quote process, we review the current requirements in A.J. LeBlanc Heating's shared pricing and rebate source and explain any incentive that applies to the proposed system.

Frequently Asked Questions
Will an air-to-water heat pump work in a New Hampshire winter?
We use the selected equipment's published performance and the home's design conditions to determine whether it can meet the load, whether backup is needed, and when backup should operate.
Can it replace my existing boiler?
An existing hydronic system can be a starting point, but this is not automatically a drop-in replacement. We evaluate emitter output, water temperature, heat loss, flow, controls, buffer requirements, and backup design.
Are air-to-water heat pumps eligible for rebates?
Rebates and eligibility change by program and equipment. During the quote process, we review the current requirements in A.J. LeBlanc Heating's shared pricing and rebate source and explain any incentive that applies to the proposed system.
How much can an air-to-water heat pump save?
Savings cannot be predicted from a statewide percentage. They depend on the existing fuel and equipment, current electric and fuel rates, required water temperature, heat-pump performance, backup operation, and installation cost. We evaluate the proposed system for the home instead of promising a standard percentage.
