Specifications

DiLiCo engineering is acting as exclusive distributor for the fuel cell heating system inhouse5000+. Based on its electric (4.2 kW) and thermal (7.5 KW) output, the system is designed for use in multi-family dwellings and buildings with high heat demand. The inhouse5000+ is intended to provide a base load supply for the building with the output. Existing condensing boilers can be used together with the inhouse5000+ system to cover peak loads in the heat supply. The building requires only a natural gas connection. Currently, fuel cell cogeneration units are subsidized by the federal government. Take your chance, DiLiCo engineering supports you with questions around the topic hydrogen heating in building energy supply.

User:

  • Commercial and craft enterprises, office buildings, hotels, restaurants, swimming pools, public buildings, care facilities, schools and many more.
  • Apartment buildings
  • Buildings with high heat demand

How does a fuel cell heating system work?

A fuel cell heater, in this case a fuel cell combined heat and power (CHP) unit, functions similarly to other CHP units. The technology makes you use cogeneration (CHP) and generates electricity and heat in one device. This can be used to heat buildings and supply them with electricity.

The fuel cell CHP unit does not, however, burn gas like conventional CHP units with gas engines, but generates electricity and heat through cold combustion. Within the heater, either hydrogen is extracted from natural gas(natural gas operation) and fed to the fuel cell, or pure hydrogen is fed directly to the system(hydrogen operation).

The hydrogen reacts with oxygen in the fuel cell and this reaction (so-called cold combustion) generates electricity and heat as well as water. Electricity and heat can now be used to supply buildings

For more information on exactly how fuel cells work, see here. Additional information on what else hydrogen technologies can be used for can be found here.

What are the advantages of fuel cell heating systems?

Fuel cell heating has some advantages over alternative technologies. However, it also makes a difference which fuel cell technology is used, as there are significant differences in the operation of the various fuel cell types.

Cross-technology, fuel cell heating offers the following advantages:

  • Highly efficient CHP technology.
  • Lowest to no CO2 emissions.
  • Lowest noise emissions.
  • No soot, no particulate matter, no combustion.
  • Low maintenance, due to few moving parts.


The biggest advantage of fuel cell heating is that the systems can achieve significantly higher electrical efficiencies than alternative technologies. As a result, more electrical energy can be obtained from the same amount of gas, which, despite rising gas prices, allows energy costs to fall.

What subsidies are available in Germany?

Fuel cell CHP units are subsidized in Germany by the KfW Förderprogramm 433 "Zuschuss Brennstoffzelle" up to an electrical output of 5 kW. The inhouse5000+ system is subsidized by this program with 29,900 EUR. More information on who is funded and how can be found here.

In order to claim the KfW funding, you need an energy consultant to confirm the project. In addition, a maintenance contract for 10 years must be concluded to ensure the operation of the system for 10 years. Both of these costs count as eligible costs.

In addition to the aforementioned KfW funding, there is also a funding by BAFA. However, this is significantly lower than the funding from KfW.

What to consider during maintenance?

The system can be maintained remotely via a network connection. Minor faults can thus be quickly rectified without the need for a technician to be on site. In addition, the plant must be checked once a year. For this purpose, the plant is taken out of service for one or two days and all necessary tests are carried out.

The costs of the maintenance amount to 2,400 EUR within Germany. These costs are fixed! There are no hidden costs for travel, spare parts or the like on you. For maintenance, the manufacturer inhouse engineering GmbH offers a 10 year maintenance contract. This maintenance contract is necessary for the funding via KfW.

You can maintain CHP plants yourself and would like to take over the maintenance of the plant yourself? Then please feel free to contact us.

What are the installation requirements?

When installing the inhouse5000+ CHP, depending on which version you are using (natural gas operation or hydrogen-only operation), there are a pair of things to consider. If you are using the natural gas powered version, you will need an natural gas connection as well as an extra flue pipe for the inhouse5000+ system. An existing flue pipe which discharges the exhaust gases of, for example, your condensing boiler must not be used.

In addition, the installation room must have a network connection, water connection and drain, and a connection to the power grid. Depending on the return temperature of the heating water, the system may also operate water self-sufficient. A generating electricity meter as well as a bidirectional electricity meter is required to measure the electricity quantities. This may vary depending on the building.

Can fuel cell heating be usefully combined?

The fuel cell CHP can be combined problem-free with existing condensing boilers and heat accumulators. Thus, you can continue to use existing technology. In addition, it makes perfect sense to look at combinations with other energy technologies. Depending on the building type and consumption, a combination of photovoltaic system and fuel cell heating makes sense

Another option would be the combination with a heat pump for buildings with very high heat demand. The electricity generated by the CHP is used to power the heat pump. Some further combinations are conceivable. For more information on combinations with fuel cell systems, see here.

Economic operation of the inhouse5000+:

  • Your annual electricity demand is above 25,000 kWh.
  • Your annual heat demand is over 100,000 kWh.
  • You have heating requirements over the entire year.
  • The electricity generated by the fuel cell is mostly consumed in the building and not fed into the public power grid.

Gas prices go up, your energy costs go down

The CO2 pricing has been extended to the transport and building sectors. This was decided by the German Bundestag on November 15, 2019. From January 2021, a price of 25 euros per ton of CO2 generated will apply. This price is to rise to 55 euros by 2025.

This will be reflected in a price increase of gas. It's time to get more out of gas! By efficiently generating electricity and heat with the inhouse5000+ fuel cell heating system, you can save on energy costs despite rising gas prices.
