Heat pumps are increasingly used worldwide as a cost-effective, energy-efficient method for heating and cooling residential buildings. 

If you really want to understand the long-term impacts of upgrading your HVAC system to a heat pump, it's best to consult people who have firsthand experience operating them. 

In a recent Reddit post on r/UKHeatPumps, a homeowner reported their full-year heat pump performance for 2025. 

In the heat pump review, the original poster reported that they have a four-bedroom, semidetached home in London with a 10-kilowatt Vaillant air-source heat pump that was installed in 2024. 


"I have an EV and cheap overnight electricity, so my hp doesn't get used in the most efficient way, as it is basically running at max for 6 hrs overnight, which is typically the coldest temperature, but with electricity at 7p/kWh, it is the cheapest," they wrote

After reviewing the specifications and usage details, the OP concluded that they are very satisfied with their heat pump experience because the house is warm and has been cost-effective. They also save energy compared with a gas boiler. 

Additionally, the OP reported that their heat pump is "absolutely silent" in operation, but that it does take up some space where it's placed in the garden, which may be a consideration for smaller properties. 

This honest review is helpful because it shows others in similar living situations how beneficial a heat pump can be and what to consider.
