Example Savings

Estimated running costs

The performance of your ground source heat pump system is impossible to predict with certainty due to numerous factors including the prevailing weather conditions and your own preferences and behaviours. For example, your heat pump will perform less efficiently during a colder winter; equally, efficiency will be impacted if you require higher-than-average room temperatures or you use an exceptional amount of hot water. That said, for illustrative purposes, Kensa has used some assumptions to estimate your running costs. If you decide to move forward, you will receive a more accurate projection once the precise heat loss has been calculated.
