Hybrid hot water or industrial central heating system

At certain times, electricity may be advantageous or locally available, while, at other times, gas offers more certainty. Energy recovery or other alternative energy sources can also play a role within your heat supply.

With a hybrid hot water or industrial central heating system, you combine different heat sources within a single integrated system. That allows you to flexibly respond to energy prices, energy availability and sustainability goals without compromising on operational reliability.

The Callens Group designs, builds and integrates hybrid heat installations that are perfectly tailored to your heat demand, existing infrastructure and long-term strategy.

Discuss the possibilities

When is a hybrid hot water or industrial central heating system worthwhile?

A hybrid system smartly combines different energy sources. That makes this thermal technology worthwhile for companies that have access to several energy sources and want to optimally respond to energy prices, fuel availability, available grid capacity, and so on.

Moreover, a hybrid installation makes it possible to add new technologies step by step. For example, an existing gas-fired installation can work together with an electric boiler, heat pump or energy recovery system. Heat is always produced by the energy source that is most attractive at that moment.

Reasons to consider a hybrid hot water or industrial central heating system:

You want to flexibly respond to fluctuating energy prices.
You have access to several energy sources on site.
You want to gradually reduce the use of fossil fuels.
You want to put electricity surpluses to good use for heat production.
You are looking for maximum operational reliability for your heat supply.

Technical specifications of hybrid hot water or industrial central heating systems

Every hybrid installation is fully designed to measure. The required output, the desired temperature, heat consumption and the available energy sources all help determine which configuration is most suitable.

In addition, our engineers look at the existing infrastructure, the control strategy, future expansion possibilities and the economic feasibility of the various technologies.

BENEFITS

Advantages of a hybrid hot water or industrial central heating system

A hybrid heat supply combines the best of several technologies. This creates a flexible system that can adapt to changing conditions. The benefits are not to be sneered at.

Fewer fossil fuels

Sustainable energy sources can gradually take over a larger share of your heat production.

Maximum flexibility

Different heat sources can work together within a single installation.

More control over energy costs

The installation can respond to fluctuating energy prices and availability.

High operational reliability

When one heat source is temporarily unavailable, other energy sources can take over your heat production.

Better grid balancing

Electric heat production can be deployed at times when electricity is abundantly available or economically attractive.

Useful use of energy surpluses

A functional and low-maintenance way to make use of energy surpluses.

What is the difference between a combined set-up, a dual-fuel boiler and a hybrid hot water or industrial central heating system?

These terms are often used interchangeably, but they refer to three different concepts.

A hybrid hot water or industrial central heating system:

A hybrid hot water or industrial central heating system combines different technologies within a single integrated energy system, for example a gas-fired boiler with an electric hot water or industrial central heating system. An intelligent control system automatically determines which technology is used at any given moment.

A hot water or industrial central heating system in a combined set-up:

A combined set-up consists of two or more separate hot water or industrial central heating boilers that each use their own energy source and together meet the total heat demand. For example, a gas-fired boiler can be combined with a biogas boiler, a hydrogen boiler or a boiler that runs on liquid residual streams. Each installation retains its own function and characteristics.

A dual-fuel hot water or industrial central heating boiler:

With a dual-fuel boiler, there is one boiler with one burner that can switch automatically between two fuels, for example natural gas and biogas or natural gas and hydrogen.

FAQ

Questions? We have the answers.

A hybrid system can combine different technologies within a single central heat supply. Common configurations are:

• gas-fired and electric hot water boilers;

• hot water boilers combined with heat pumps;

• gas-fired installations combined with energy recovery;

• biogas or hydrogen applications alongside existing installations;

• combinations of several heat sources within a single central heat network.

The Callens Group specialists analyze your situation and advise you on the combination that is most attractive, technically and economically. Contact us.

The switch happens fully automatically via an intelligent control system. It takes into account parameters such as energy prices, heat demand, available output, grid capacity and any sustainability goals. This way, the installation produces heat at any given moment via the energy source that is most attractive technically and economically.

Yes. By flexibly switching between different energy sources, the installation can respond to fluctuating energy prices. When electricity is cheap, more can be produced electrically. When another heat source is more economically attractive, that takes over. This can significantly optimize the total energy cost of your heat production.
