What are the maintenance requirements and costs for an ASHP?​

To keep your heat pump running smoothly, it’s important to service the heat pump, cylinder, and controls annually. It’s also a requirement of most manufacturers’ warranties to have the heat pump serviced every year.

The cost of an annual service typically ranges from £200 to £350, including VAT at 20%. Pay-monthly service plans may also be available.

Typical service tasks include:

– Cleaning the evaporator and outdoor unit

– Cleaning system filters

– Servicing the hot water cylinder

– Recharging expansion vessels

– Monitoring and optimizing the heat pump controls and performance

– Maintaining exterior pipework insulation

Things you can do yourself include:

– Keep system pressure between 1 and 1.5 bar

– Report any leaks or faults as soon as possible

– Refrain from changing settings that your trusted installer has configured for optimum comfort and performance

A heat pump can last up to 25 years, depending on installation quality, design, product, servicing, and usage. Manufacturer warranties typically cover the heat pump and controls for 5-7 years, hot water cylinders for 25 years, and other components for 2 years.

In short, regular servicing helps ensure your heat pump performs at its best for many years, delivering reliable comfort and energy efficiency.
