To see how your heat pump has been performing, visit the Performance stats page.
On this page you can see an estimate of how much your heat pump costs to run per day total, as well as weekly figures for CoP and energy usage broken down by heating/hot water.
How and when does the Performance stats page update?
The page updates once a day at about 1200 UTC (1200 GMT/1300 BST)
How is the effective tariff calculated?
Havenwise estimates your effective tariff from when and how hard your heat pump has been running, and how much it cost to run at that time. It is the total cost of energy/total energy consumed
Note that the first day you connect to Havenwise this value will be wrong, because this is a partial day of data and we can't know for sure what time of day the heat pump ran. All subsequent days will be fine.
