Common air source heating problems involve loss of heat generation, lack of representation in cooling temperatures, noise, ineffective location, and poor installation. Can avoid these problems by using a legitimate installer.
Domestic heat pump water heater is an exceptional renewable technology to provide your home with heat and hot water; they can experience reduced performance if not correctly planned and established. Here, we expect to highlight some of the more common obstacles that can occur with Air Source Heat Pumps and what to consider when designing your home’s energy-efficient tomorrow.
What is an air source heat pump?
Simply put, an air source heat pump (ASHP) is a way to heat your home and provide you with hot water, just like a boiler. But instead of burning fossil fuels, ASHPs use a small amount of electricity to collect a large volume of low-grade heat from the air, transforming it into high-grade heat for your property.
While this sounds straightforward, some complex processes are occurring within the heat pump when you look a little closer. Air is drawn into the heat pump using a fan and passed across a large heat exchanger. Inside the heat exchanger is a very cold refrigerant, and the refrigerant absorbs heat from the air.
The heat pump then uses a cooling cycle to reduce the refrigerant, making it heat up, and this high-grade heat is then used to heat your home and hot water. In conclusion, the same system holds the space inside a fridge cold, but alternatively of transferring heat from the freezer part and depositing it into the kitchen, a heat pump stores heat from the environment and move it into your home.
Possible air source heating difficulties
As with most production equipment, air-source heat pumps can experience crashes from time to time. Problems with an ASHP, just like any heating system, can significantly affect your home and quality of life, so it is essential to be informed of them from the preparation boards of your project.
1. Poor design
Nearly all problems with an air source heat pump system can be traced back to a poor initial design. If the heat pump manufacturer hasn’t undertaken suitable or accurate heat loss calculations for the building, adequately designed the heat pump or the heating distribution system (i.e., under floor heating, radiators, etc.), the system will likely operate poorly.
2. Poor installation
Inadequate installation of the heat pump unit and associated pipework plays a big part in your unit's efficiency and longevity. The use of incorrect or insufficient quality parts and substandard quality by heat pump suppliers will mean that your company cannot run to its full potential.
3. Freezing temperatures
A Heat pump water heater is usually designed to operate at outdoor temperatures as low as -15C to -20C, but the choice of machine is critical to ensure it can provide enough power to keep your home warm. Must take your home's location and the height above sea level into account during the design stage.
A heat pump system designed following the Microgeneration Certification Scheme should provide 100% of your heating and hot water needs under design conditions for the locality.
However, even if the system is designed correctly, you should check your heat pump during periods of heavy snowfall or prolonged sub-zero temperatures to ensure snow and ice don't build up around the fan or heat exchanger.
