Air Source Heat Pumps are revolutionising the way that we heat our hot tubs and swim spas. Vian Power’s innovative technology can make a significant difference in both energy efficiency and cost-effectiveness. In this blog post, we’ll explore how Vian Heat Pumps work, and explain their real-world testing results.
Understanding Coefficient of Performance (CoP)
The key to the efficiency of Vian Power Air Source Heat Pumps lies in their Coefficient of Performance (CoP). This value represents the ratio of heat produced to electricity consumed. A CoP of 8 means that for every 1 unit of electricity consumed, the heat pump produces 8 units of heat. On the other hand, traditional electric heaters have a CoP of 1. This means that they produce only as much heat as the electricity consumed.
Different Types of Technology
Vian Power offers various types of air source heat pumps, including ON/OFF models and Inverter models. Inverter models have the advantage of adjusting power consumption based on ambient temperature and heating demand. As a result, this makes them more energy-efficient and quieter. Comparatively, full DC Inverter models take efficiency to the next level by regulating power consumption over a fluid range. Full DC Inverter models are the most efficient and quietest option in the long term.
Real World Testing Results
In order to showcase the real-world benefits of Vian Heat Pumps, we conducted a 10-month test period from December 2022 to September 2023, focusing on the heat pump’s power consumption to maintain a set point of 40°C. As a result, the kWh used over this period was 749.55. According to Ofgem, from the 1st of October 2023, the new kWh rate will be set at 27.35p. With the kWh rate set at 27.35p, the cost for this 10-month period would be approximately £205, equivalent to just £20.50 a month.
Environmental and Cost Benefits
By using significantly less energy compared to traditional heating methods, Vian Heat Pumps benefit the environment whilst saving hot tub and swim spa owners a substantial amount of money.

These recordings and data are only for representative purposes as there are so many variables with different locations, temperatures and usage that could result in different figures. Although these are not independently vetted, tests were performed to measure the kWh power consumption of the Vian 7kw S7 plus heat pump to show some of the real-world results. A simple inline kWh meter that connects to a smart home system was used to measure and record the usage.
kWh rate is correct as of 1st October 2023, according to Ofgem. Source: https://www.ofgem.gov.uk/publications/energy-prices-fall-again-winter
