Want to save money and increase the comfort in your home? A ductless heat pump (DHP) might be the answer. With the reduction in oil prices, some may question the timing of this type of investment. However, as history has shown us, energy costs can change quickly—trends don’t always suggest a multi-year decline in oil prices.
What is a ductless heat pump?
A DHP is a zonal heating and cooling system that does not require “air ducts,” making it ideal for homeowners who want to replace their current heating system, but don’t want the expense or inconvenience of ductwork. Typically, the system includes an outdoor unit and one or more indoor units that are linked by a refrigerant line. It operates a bit like a space heater or window air conditioner—you can control the indoor units where and when you need extra heat or cooling—but it is far more efficient and safer. They are flexible, and come in different sizes to suit your home’s configuration. Originally recommended for milder climates, current models are equally suited for colder climates as well.
What are the benefits?
Homeowners have found that a DHP provides even, comfortable heat, where and when they need it. This increased comfort comes with a lower utility bill – the increased efficiency means that ENERGY STAR-rated units typically use 25 to 50 percent less energy than other types of heat. (Check out this handy calculator from Efficiency Maine to compare savings among heat sources.)
They also offer better indoor air quality benefits, and finally, they are aesthetically pleasing in a home: they can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Many have remote controls for ease of use.
What type of home are they best for?
Ductless systems can be used in all types of homes: remodels, additions, new construction, existing homes and even manufactured homes. Use them to replace inefficient systems such as an electric baseboard, wall or ceiling units and even woodstoves. They are an excellent alternative to “ducted systems,” which are more expensive and sometimes not possible because of a home’s configuration.
Is this a new technology?
DHPs have been used in Japan since the 1970s and are a dominant technology in Europe as well. As their benefits become better known, they are gaining popularity across the United States. According to Navigant Research, by 2020, ductless systems will account for nearly 30 percent of all energy-efficient HVAC systems revenue.
What are the costs?
Installation varies, based on the size of your house and the system you choose, but typically costs between $3,000 and $5,000. Tax rebates and incentives may be available from your local installer and utility provider. In addition, homeowners can expect to save monthly for years to come in the form of lower utility bills—every single month! The ongoing maintenance typically includes an easy regimen of ensuring the filters and coils are clean.
DHPs are an excellent alternative for homeowners looking to increase the efficiency and comfort of their home.
