Ductless Heat Pumps Versus Refrigerant Heaters

When considering heating and cooling, ductless heat pumps are becoming increasingly popular because of their energy efficiency, flexibility, and relative ease of installation. As well, in recent years new developments have resulted in even more significant energy savings, making them the preferred technology for commercial and residential applications. The cost advantages of ductless heat pumps depend on several factors, such as the efficiency, duct system condition and location, power source, climatic zone, and energy usage. A well-installed ductless heat pump can save up to 50% of your central heating and air conditioning bills in some Canadian cities.

Ductless heat pumps can be installed in either a ductless split system or in a ductless mini-split system. A ductless mini-split system involves installing two ducts in each room or area, whereas a split system connects two ductwork in each room or space. In a split system, air passes through two ducts, one going from the indoor unit to the outdoor units, while the other duct travels from the outdoor unit back to the indoor unit. In either case, the outdoor condensing unit heats the air and sends it through a single line, or ‘sink’ into the indoor condensing unit.

The installation of ductless heat pumps involves many factors. Two major factors involve the size of your rooms and the total square footage of your house. If you live in a small apartment or condominium, then you will probably be able to install a mini-split or split system. Typically, you will need to consult with an HVAC (heating, ventilation, and air conditioning) professional in your city or area to find out the size of your ductwork and to find out how much power and/or ductless heat pumps you will require. The amount of power you need will also depend on how many refrigerators, freezers, dishwashers, and other central air conditioning equipment you have, as well as the age of these appliances.

Another factor that will affect your decision is whether you are using forced air or natural gas and whether you have installed ductwork in your home. Ductless heat pumps can be used in conjunction with existing heating systems to provide enhanced indoor temperature control. This type of heating and cooling system does not require ductwork, so many homeowners don’t even have to worry about installing ductwork in their homes. Even if you don’t have existing HVAC equipment, installing ductless heat pumps can be less expensive than upgrading to a new heating and cooling system.

Some people are concerned that ductless heat pumps cannot effectively handle extreme cold or heat. In fact, these devices are designed to work in any weather condition and with any type of climate. In addition, with today’s technology, they are also often more energy-efficient than older versions. The most efficient ductless heat pumps utilize less energy than their refrigerant counterparts, which helps to keep your HVAC costs down. In climates, that experience temperatures of zero degrees or below, these mini-split heat pumps are often the only solution to indoor temperature control.

Although they do require less maintenance than their refrigerant counterparts, ductless heat pumps do require periodic service. Although they can operate independently, regular tune-ups may be necessary to maintain your unit’s efficiency and operational capability. While the average homeowner doesn’t require routine upkeep, HVAC professionals recommend that at least two of these systems be checked out annually. When properly maintained, refrigerant gas models continue to operate efficiently for many years.
