Heat pumps have revolutionized energy efficiency in modern homes. They offer both heating and cooling while minimizing energy costs. Yet, many homeowners still miss out on maximizing their heat pumps' effectiveness. This post will explore solid hacks to help you get the most from your heat pump, ensuring comfort and savings every month.
Understanding Your Heat Pump
Knowing how your heat pump operates is essential for optimal performance. These systems transfer heat using electricity, moving it instead of generating it. This process makes them highly efficient. For example, most heat pumps can deliver over three units of heating or cooling for every unit of energy consumed.
However, performance can suffer from poor maintenance and incorrect use. By recognizing this efficiency, you can set yourself on a path to enhanced performance and lower bills.
Regular Maintenance: The Key to Longevity
Regular maintenance is vital for keeping your heat pump efficient and long-lasting.
Simple system checks
Checking heating / ground array system pressure
Check evaporator coil and ensure it's clear of any obstructions
Make sure the fan is free from any debris / obstructions
No fencing or barriers surrounding the heat pump
Check filters if confident to do so
Schedule Professional Servicing
Highly recommended to schedule in yearly servicing from a qualified heat pump engineer. This ensures your system gets a full in depth service and will prevent voiding manufacturers warranty.
Optimize System Settings
Efficient heat pump use also involves fine-tuning its settings.
Adjusting your heat curve
Adjusting your heat curve is crucial for maximizing system efficiency. It is recommended to fine-tune your heat curve during the winter months for a more precise set point.
Top Tip: Start your heat curve low (so room temperatures are cold) and very gradually increase, ensuring a minimum of 24 hours in between any further adjustments. This is to ensure your heat curve is set as low as possible when achieving target room temperature.
Room stats / Zoning
To maximize system volume flow and efficiency, it is recommended to minimize or eliminate zoning in your heating system. When individual zones are closed, they will decrease in temperature. Upon opening to heat the zone, colder flow system water will flood the system, causing the heat pump to work harder to reach the target flow temperature.
Top Tip: When using zones, typically regulated by a room thermostat or timer, aim to keep your system running for extended periods. Set timings for broader time frames and utilize room thermostats to establish temperature limits instead of specific target temperatures. This approach will optimize system flow, sustain flow temperature, and lead to increased efficiency.
Night time setback
Enhancing sleeping comfort can be achieved by reducing the temperature in your bedroom during the night. Numerous heat pumps and thermostats come with a nighttime setback function. It is advisable to decrease the temperature by only 2-3 degrees Celsius when utilizing this feature. Although this may help in reducing operational costs, setting the setback to over 3 degrees could result in higher expenses and decreased efficiency in the long run. This is because the heat pump will need to work more vigorously during the day to compensate for the temperature drop at night.
Room Comfort
It is a common practice to close off radiators in unused rooms, but doing so can lead to adjacent rooms struggling to reach the desired temperature. Heat naturally moves from warmer areas to colder ones, so if you have your main bedroom heated while the radiator in the spare bedroom next to it is closed off, the spare room will be colder than the main bedroom. This can result in the heat from the main bedroom escaping to the spare room, making it harder for the main bedroom to maintain its temperature and causing the heat pump to work harder and longer to reach the desired temperature. To maintain a more balanced house temperature and improve efficiency, it is recommended to keep all radiators open, even in rooms that are not in use.
Hot Water
Typically, individuals shower or bathe in water temperatures ranging from 38 to 40 degrees Celsius. When adjusting your hot water temperature, consider the actual necessity of extreme heat. Excessive heating of water can impact efficiency. Lower temperature settings can help minimize operational expenses. Consider programming your heat pump to warm your hot water during the mid to late afternoon, when air temperatures are higher, to maximize the efficiency of your air source heat pump. Take advantage of flexible energy pricing plans offering discounted electricity rates during night time hours. Although scheduling your heat pump to heat water during these periods may reduce efficiency, it can lead to cost savings.
Mastering Your Heat Pump for Comfort and Savings
Implementing these heat pump hacks can significantly enhance your system's efficiency and longevity. Combining regular maintenance with smart usage and home adjustments makes a noticeable difference in comfort while saving you money.
With mindful energy practices and a commitment to ongoing optimization, you can effectively master heat pump usage. Your wallet will appreciate it, and your home will stay comfortable, no matter the season.
To Summarize:
Keep evaporator coil clean and free from any obstructions
Fine tune heat curve during winter months, start low / cold and gradually increase
No / minimal zoning, when zoning used extended timing periods / use stats as limiters
No greater than 3 degrees night time setback
Do not set hot water temperature any hotter than it needs to be
Heat all rooms in your home, do not shut off rooms that aren't being used
Yearly service from a trained engineer
