Air to Water Heat Pump Systems for Efficient Home Heating
An air to water heat pump transfers heat from the outdoor air into water that can be used for radiant floor heating, radiators, fan coil systems, and domestic hot water. At Ductless Certified Heat Pump, we provide modern heating solutions designed for energy efficiency, lower operating costs, and year-round comfort.
Many homeowners choose an air to water heating system because it can replace or supplement traditional boilers, furnaces, and water heaters. These systems are especially popular for new homes, renovations, radiant floor heating systems, and properties looking to reduce energy consumption.
A modern hydronic heat pump can be used with in-floor heating, low-temperature radiators, snow melting systems, and domestic hot water tanks. Many systems can also be combined with solar panels, backup heating equipment, or other energy-efficient HVAC technologies.
We also provide complete heat pump installation, fast heat pump repair, regular heat pump maintenance, and full heating and cooling system upgrades.
How Air to Water Heat Pumps Work
An air-to-water system absorbs heat from the outside air and transfers it into water through a refrigeration cycle. That heated water can then be distributed through radiant floors, radiators, or air handlers throughout the home.
Many systems can also provide domestic hot water for showers, sinks, and appliances. Some advanced models can even provide cooling during warmer months by circulating chilled water through compatible systems.

Why Certification Matters
Air-to-water systems require proper design, water flow balancing, refrigerant handling, and equipment sizing. Our team includes a licensed Gas Technician 1 technician, a 313A Refrigeration and Air Conditioning Mechanic, and a fully TSSA certified gas contractor. We are also an HRAI member with full WSIB coverage and insurance.
Rebates, Coupons, Financing, and Rentals
Many homeowners may qualify for a ductless rebate, energy-efficiency grant, or heat pump incentive when installing an air-to-water system. Customers can also save with seasonal coupons, flexible financing options, and affordable rental programs.

Benefits of Air to Water Heat Pumps

Air-to-water systems can lower heating costs, improve comfort, reduce greenhouse gas emissions, and provide more consistent indoor temperatures. They are especially effective in homes with radiant floor heating or low-temperature hydronic systems.
Because they use electricity instead of fossil fuels for most heating needs, air-to-water heat pumps can also help homeowners reduce dependence on gas or oil heating systems.
