Heat Pump Basics: What You Need to Know for System Safety
There is no place like home. However, the home environment can sometimes be uncomfortable, depending on the season of the year. During winter, a heat pump serves an integral function of keeping your home warm.
The U.S. Department of Energy reports that the use of a heat pump can result in a reduction of energy costs by 82% to 97%, considering the installation efficiency. Consequently, heat pumps are a great alternative to air conditioners and furnaces for all seasons.
Heat pumps are ideal tools for cooling and heating the indoors. But how much do you know about enhancing the system's safety? Let's discover more about heat pumps and how you can enhance their efficiency.
Types of Heat Pumps
There are two main types of heat pumps: ductless and non-ductless (connected by ductwork). The Department of Energy reports that heat pumps can reduce your heating consumption using electricity by up to 75%.
Pumps that use ductwork are a popular choice because they offer both cooling and heating. They do so through ducts, enhancing their ability to provide uniform temperature increases for all rooms.
Ductless heat pumps are ideal for zonal heating needs, and they require less energy. Air-to-water heat pumps use hot water to provide heating through radiators or radiant floors. These types of heat pumps do not offer cooling.
How Heat Pumps Work
Heat pumps run on the principle of thermodynamics, making use of a system of expansion and compression to move heat. A heat pump consists of a compressor that's capable of moving a refrigerant which extracts heat from the air.
The heat is then passed through the system and delivered either through an under-floor system or radiators. Some of the key components of heat pumps include:
Indoor and outdoor coils
Expansion and reversing valve
Refrigerant and compressor
The outdoor coil absorbs heat from the air and directs it to the refrigerant, while the compressor pressurizes the air, making it hot and moving it through the indoor coil. The whole cycle releases its heat into the indoor area of your home. As the hot air cools, it transforms back into liquid.
The cooling process of heat pumps works in reverse. This means that the indoor coils absorb heat from the indoors, cool it, and then the outdoor coil releases it through the outside coil.
Heat pumps produce energy-efficient heating because they don't generate heat. They simply transfer it from one area to another. According to the International Energy Agency, heat pumps are 3-5 times more energy efficient than gas boilers.
Steps Involved in Heat Pump Installation
Proper installation is essential to enhancing the safety of your heat pump. HVAC install technicians can help you plan and execute the installation process successfully. Some of the steps involved in safely installing a heat pump include:
Planning and Assessment
Prior to the installation process, evaluate your home by analyzing factors such as:
Size
Existing heating system
Home layout and insulation
Availability of water and ground space
A specialist can assess your home and help you decide the best heat pump that meets your needs. These technicians have experience using different heating systems. So, they can provide you with insights that can guide your decision-making.
Working with a technician also ensures you stay compliant with all local regulations and the manufacturer's specifications.
Heat Pump Selection and Installation
You can choose between a water-source, ground-source, or air-source heat pump. Residential heat pumps can be ductless or come with ducts. Modern heat pump systems also offer multi-zone and single-zone configurations.
Consider your heating needs, especially during cold seasons, when choosing between different options in the market. The installation procedure can follow the steps below:
Mount the outdoor unit somewhere secure and stable
Put the indoor heat system on the wall
Drill a hole for the refrigerant lines and other electrical connections
Seal and insulate all the lines to minimize leaks to energy loss
If you have opted for a heat pump requiring ductwork, inspect it for leaks or any damages. The installation process can become complex. So, consider working with an HVAC technician who can help you to install your heat pump safely.
Besides installation, HVAC specialists can provide home heating maintenance services. These help you reduce the long-term cost of operating a heat pump.
Post Installation Testing
Heat pumps need to be thoroughly tested to ensure they're safe and running correctly. An HVAC contractor can help you with duct cleaning, plumbing, drain cleaning, and any other task required for the smooth running of your heat pump.
The contractor will run system checks and conduct operational tests to ensure that there is excellent cooling and heating. Having a specialist test out the heat pump is also necessary if the system requires adjustments to function.
How to Properly Operate a Heat Pump
Operating a heat pump safely begins by understanding how the system works. Start by learning the basic thermostat functions or remote-control inputs of the system. Use a programmable thermostat that lets you enjoy different features.
You should turn off the fan if no one is home. Continued fan use can adversely affect the performance of the heat pump. Use the auto fan feature on the thermostat to enhance the efficiency of the heat pump.
Maintenance and repair are other essential factors that will help you enhance the safety of your heat pump system. An HVAC technician can assess the condition of your heat pump by:
Inspecting filters, ducts, and the indoor and outdoor coils
Removing any obstruction
Measuring the airflow and refrigerant charge
Checking for leaks
Verifying the electrical connections are working
Regular inspections and maintenance work are necessary at least twice a year. The cost of regular inspection can be high, so consider choosing an HVAC contractor with a membership package that covers such expenses.
