As heating and cooling technologies improve, more homeowners are replacing air conditioners and furnaces with heat pumps. This is because of the many benefits that a heat pump has e.g. cooling homes during summer and warming them during winter. You might want to know more reasons they are preferred to typical HVAC units, their cost, and how they actually work.
How they work
Like the air conditioners, heat pumps are installed outside the home and connected to an electric baseboard, air handler, or the furnace. An air-to-air pump passes air through the refrigerant to release or absorb heat. During a cold season, warm air is pumped inside the house while in summer; the warm indoor air is pumped out. A well-maintained pump lasts 20-25 years. Heat pump prices may be high at first but they are worth in the end.
The main advantage of a heat pump over a typical AC and furnace is energy efficiency. Pumps use minimal electric energy to reverse the flow of heat or cold. For every kilowatt of energy used, a pump can produce up to 3KW. As a result, the cost of heating and cooling is reduced. The other benefit of a pump is comforts. The effects of this system are less intense than other systems. So, no abrupt surge of heat or cold occurs. In addition, ductless pumps work even in extremely cold conditions (-22⁰F). Depending on your needs, a ductless pump would be a better option.
The cost of installation is determined by a number of factors. For instance, a single air-to-air pump costs 4 times less than house units. The cost factors include the energy rating of the unit and the home size. Expensive devices have higher ratings. Geothermal pumps are more expensive to install since they require more work i.e. excavation. If you install a residential air-to-air pump, you might still need a furnace for supplementation. However, heat pumps NZ can do both duties of warming the house in winter and cooling it in summer; so you will save on the cost of maintaining air conditioner and furnace. Always hire a pro to help you with the installation. Note that the best installer is a refrigeration technician and not an electrician. You need someone who understands the refrigerant. Most companies provide both professionals in addition to other technicians. How long it takes to install depends on the size and complexity of the job. Sometimes, the pump has to be installed opposite the furnace and this will require more ductwork and wiring.
What is a reverse cycle heat pump?
If you live in the southern parts of New Zealand you already know how it feels like during winter months. Reverse cycle pumps should be your go-to options. In essence, a reverse cycle pump is one efficient unit that heats up your house in winter and cools it in summer. It is the most energy efficient units. It is very different from typical electric heaters which must generate heat. However, this one used the outdoor air heat to warm the indoor air. This unit is built with the cold condition in mind. It has an automatic defrost cycle such that it can still heat your home even when temperatures drop as low as negative15⁰C
In summer, reverse cycle pumps switch to a cooling mode. They absorb indoor heat and distribute it outside through an ultra energy efficient system, leaving a cool indoor. They can cool your house temperatures over 30⁰C.
The modern reverse cycle pumps are flexible and adaptable. They come with inverter technology and thermostats and that’s why they can adapt to the conditions and temperatures of a room. If you are looking for a heat pump in Auckland, consider one with the inverter technology.
