Maintenance of Heat Pumps

Views:1     Author:Site Editor     Publish Time: 2018-06-15      Origin:Site

A good quality and well installed air or ground source heat pump system will require relatively little maintenance and can be expected to last for at least 20-30 years. Installations require an annual check which can be done either by the system’s owner or by a qualified installer or engineer. Your installer/supplier should give you details of your system’s exact maintenance requirements, and also of how to optimize your system’s performance.

 

Air source heat pump maintenance

“What are the maintenance requirements of an Air Source heat pump?”

It should please those that are looking to acquire an air source heat pump that they require very little on-going maintenance. Every unit will be different, of course, but manufacturers will advise consumers as to what their exact unit requires in regards to annual or seasonal maintenance.

The maintenance you can perform to ensure the unit operates as intended is:

· Clean and or swap out filters

· Clean coils and fans (if necessary)

· Ensure proper air flow is not impeded by debris (leaves, dust etc.)

· Clean the supply and return registers inside the property

· Power off the unit and check / clean fan blades.

Before the winter (or summer if used for cooling) it is recommended to have the unit serviced by a professional who will conduct a more advanced audit of the components and identify issues that could degrade the heat pump’s performance, which a user would not spot or be able to diagnose. These checks will comprise of the following:

· Check ducts for leakage and repair if necessary

· Inspect filters, ducts, blower and indoor coil for dirt and other obstructions

· Measure airflow is correct

· Check refrigerant levels and pressure

· Check all electrical contacts and ensure they are protected from the elements

· Check for system leaks

· Check reverse heating / cooling controls and verify they are operating as required

· Lubricate moving belts, motors and check for damage / wear and tear

· Check and test thermostat under normal operating conditions.

For the most part and unlike other renewable energy technologies, such as solar PV and wind turbines which use costly inverters, heat pumps do not generally require the replacement of expensive parts during their lifetime.

 

Heat Pump Warranties

 

The majority of air and ground source heat pump systems come with a 5-10 year warranty on parts and labour as standard, although well maintained systems may last much longer than this (perhaps 20-40 years). Many systems will also include free annual services, although this depends on the chosen manufacturer and installer.
