Air Conditioners for All-Electric Homes
Air conditioners are a cost effective option for all-electric cooling and heating. There are many types on the market today. Therefore, weigh up the pros and cons to find the type that best suits your house and budget.
Consider combining reverse cycle air conditioners (RCACs) with hydronic heat pumps. This makes a lot of sense for two storey homes. This is because RCACs are best at cooling whilst hydronic heat pumps are best at heating. However, both systems also do the opposite.
RCACs & Hydronic Heat Pumps
RCACs work by blowing conditioned air through ducting or from room based indoor units. This is a perfect method for cooling which also benefits from the air movement. Air movement alone can make you feel about 4 degrees cooler.
However for heating, it is better radiated without air movement, which is how hydronic heat pumps work. They use water to transfer heat from an outdoor heat pump to wall mounted radiator panels or though underfloor pipes. Then these systems gently radiate heat into your room.
For a two storey house, install radiant hydronic heat pumps on the ground floor because heat rises and install RCACs on the first floor because cool air falls.
For a single storey house, consider air conditioning your bedrooms with RCACs and using hydronic heat pumps for your kitchen and living rooms.
Types of Air Conditioners
Reverse cycle air conditioners are often ducted systems. This is because they are cost effective and provide excellent control. Feel the evenness of air distribution in all of your rooms when you system is properly balanced. Zone rooms for individual control with separate temperature settings.
Some of the major benefits of ducted air conditioning are:
- Control: central temperature setting with minor room zone controls
- Even air distribution: every room has even heating and cooling
- Value: for multiple rooms, it is cheaper to install ducted air conditioning than wall hung split systems
- Aesthetics: the only intrusion to the room is a flush mounted vent that blends with the ceiling
Explore the other types of RCACs available on the market. There are also a range of indoor units that deliver the conditioned air to your rooms. Some are wall mounted, some are concealed above ceilings. Cassette types are mounted in your ceilings and can blow air from 1 to 4 directions.
