Use this category for costs incurred in connection with the **heating meters**.

These include, for example, costs for:

* renting heating and hot water meters
* calibrating heating and hot water meters
* maintaining or replacing heating and hot water meters

#### Assignment

For the assignment select **"Property"** and then the property concerned.

The costs are thereby assigned to the entire property and allocated to the tenants as part of the operating cost statement.

#### Important

Only enter costs here that relate directly to **heating and hot water meters**.

{% hint style="info" %}
Costs for cold water meters or other types of meter should not be entered in this category but in the appropriate type of cost.
