Master data in the object
In order for Immodio to be able to correctly prepare the heating costs and hot water bill, the technical master data of the heating system must be maintained in the property. This information determines which cost types, consumption values and meter readings are relevant for billing.
The most important information is:
Energy sources for heating
Energy source for hot water supply
Indication of whether central heating is available
Central heating flow temperature
Indication of whether there is a gas or oil tank
Distribution of operating costs according to area and consumption
Energy sources for heating
The energy source for the heating indicates the energy with which the space heating of the property is operated.
Typical energy sources are, for example:
Heating oil
central oil heating
Natural Gas
Gas Central Heating
LPG
Gas tank on the property
District heating
Connection to a district heating network
Electricity
electric heating or heat pump
Pellets / Wood
Biomass Heating
In the case of grid-bound energy sources such as natural gas, district heating or electricity, consumption is usually determined via utility bills or main meter readings. In the case of storable fuels such as heating oil, liquefied petroleum gas or pellets, it must also be taken into account how much fuel was still available at the beginning and end of the accounting period. For more information on storable fuels, see here.
Energy source for hot water supply
The energy source for the hot water supply indicates the energy used to generate the domestic hot water.
In many buildings, the energy source for heating and hot water is identical, so that the central heating system generates both space heating and hot water.
Heating oil
Heating oil
Central oil heating with hot water tank
Gas
Gas
Gas central heating with central water heating
District heating
District heating
District heating for heating and hot water
Heat pump
Heat pump
Central heat pump for both areas
However, there may also be different cases:
Gas
Electricity
Heating centrally, hot water decentralised via instantaneous water heaters in the units
Heating oil
Solar thermal energy + heating oil
Hot water is partially solar supported
Central heating
The Central heating option must be activated if a common heating system supplies the entire property with heat.
Typical examples:
a boiler in the basement supplies all apartments
yes
District heating connection supplies the building
yes
Central heat pump supplies all units
yes
each apartment has its own gas boiler
yes
each apartment has its own electric heaters
yes
Hot water via instantaneous water heater in every apartment
for hot water not central
Central heating has an impact on billing:
In the case of central heating, the total costs are therefore initially recorded at the property level. They are then distributed to the individual units based on the existing meters, consumption values and distribution keys.
Central heating flow temperature
If there is central heating, the flow temperature of the central heating can be maintained.
To do this, first select the tag "Central heating" under "Energy equipment".
Now you will be shown the input field for the flow temperature.
Typical orientation values:
older radiator system
approx. 60–75 °C
modern radiator system
approx. 45–60 °C
Underfloor heating
approx. 30–45 °C
Heat pump with low-temperature system
often approx. 30–45 °C
Gas or oil tank
The Gas/Oil Tank option should be activated when the energy source is stored in or on the property and replenished by deliveries.
Heating oil
yes, oil tank
LPG
yes, gas tank
Pellets
yes, pellet storage
Wood
yes, stock available
Effects of the gas or oil tank – quantity and quantity consumed
In the case of heating oil, liquefied petroleum gas or pellets, the quantity purchased in the accounting year does not necessarily correspond to the quantity actually consumed in the same period. The reason for this is that the central tank stock is usually not completely empty or completely filled at the beginning and end of the billing period.
So when the tank is filled at the end of the year shortly before the billing date, this delivery has been paid for, but accordingly not yet fully consumed. Conversely, fuel can be consumed in the current year that was already purchased in the previous year. Therefore, the initial inventory must also be taken into account.
The formula is:
For the heating cost bill, the quantity consumed is generally relevant, not only the quantity purchased. In the case of heating oil, consumption is usually determined from starting stock plus deliveries minus ending stock.
If you determine the total consumption in step "5. Heating and hot water consumption", you can enter the consumed amount of the energy source as well as the cost of the consumed amount of the energy source.
Distribution of operating costs according to area and consumption
For heating and hot water costs, the Heating Costs Ordinance applies. It generally prescribes consumption-based billing. This means that heating and hot water costs may not be distributed entirely by square metre.
The Heating Costs Ordinance provides that part of the costs are distributed according to consumption and part according to area. For heating costs and hot water costs, the consumption-dependent share is generally between 50% and 70%. The remaining share is distributed by area.
You can set the desired division in the property in the "Billing" tab. Further information on the correct distribution of operating costs according to area and consumption as well as the possibilities to set them individually in Immodio for the respective property can be found here.
