All GHP models and sizes have a service interval of 10.000 hours. Generally the lifetime is calculated for max. 30.000 hours. If the GHP is used for cooling & heating all year round take care about operating hours! One year = 8.760 hours. If the project will result in such a kind of operation the GHP is not suited for this need as it would mean replacement of the unit after only 3,5 years. Normally operating hours should not exceed 2.000 – 3.000 hours a year! It is recommended to use the timer functions for stopping operation at weekend, holiday, night time etc. As GHP basic operation principle is to keep stable room temperatures by smooth operation (low rpm.) it is very important to keep in mind this point for economic long time operation.
