Help on the category Heating and hot water (recoverable from tenant).

Use this category where both the heating and the hot water for the entire building are supplied by **the same system**, for example by a central heating system.

Enter costs here that arise jointly for heating and hot water and cannot be assigned unambiguously to just one area. These include, for example, fuel or energy costs for the central heating and other recoverable costs concerning the entire heat and hot water supply.

**Typical expenses are, for example:**

1. A gas invoice for the central heating system\
   For example payments on account or the annual statement from the gas supplier, where gas is used for heating and for producing hot water.
2. A heating oil invoice\
   For example a delivery of heating oil including delivery costs for the combined heating and hot water system.
3. Pellets, wood or other fuels\
   For example fuel deliveries for a pellet heating system that supplies heating and hot water.
4. A district heating invoice\
   For example the charge for heat supplied, where the building is supplied with heating and hot water by district heating.
5. Rental of a gas or oil tank.\
   For example the running rental costs of an LPG tank or oil tank needed to operate the combined heating and hot water system.
6. Maintenance of the heating system\
   For example regular maintenance by a specialist company, including checks of operational readiness and operational safety.
7. Cleaning the heating system and the plant room\
   For example cleaning the boiler, burner, flue system or boiler room, as far as it serves the running operation.
8. Chimney sweep and emissions protection measurements\
   For example flue gas measurements or measurements prescribed by law under the German Federal Immission Control Act.
9. The costs of recording consumption\
   For example the rental, leasing or use of heat cost allocators, heat meters or hot water meters, as far as these are needed to bill the system.
10. The costs of billing and allocation\
    For example the costs of a metering service provider for reading, calculating and allocating the heating and hot water costs.

Immodio then splits these joint costs into a heating cost share and a hot water cost share for the statement.

Where heating and hot water are produced **separately**, do not enter the costs in this category but separately under **"Heating"** and **"Hot water"**.

{% hint style="info" %}
Repair costs do not belong in this category, because they generally may **not** be recovered from the tenants.
{% endhint %}

Only use this category where heating and hot water are produced by a combined system.

Where heating and hot water run on separate systems and the costs are shown separately, enter the costs separately in the categories **"Heating"** and **"Hot water"** instead. You can find further information on billing with separate systems for heating and hot water [here](#id-2.-getrennte-systeme-fur-heizung-und-warmwasser).
