This start-up entrepreneur knows exactly what’s what and really wants to heat up the market.

Heating costs far too high? Problems or dissatisfaction with your current heating system? Purchasing a new heating system too complex? Don't know any good heating engineers? Martin Teichmann, founder and managing director of Kesselheld is now an expert on heating systems. He and his company make it easier for you to buy and change your heating system.

"We make it easy for heating customers to get information, obtain a quotation, understand the subject of grants and financing and ensure your new system is perfectly installed by a local heating engineer."

Before Kesselheld, it wasn't that easy. The heating engineer market is very fragmented and there are 53,000 heating engineering companies in Germany alone, all offering their own solutions. How can the customer know which is the right solution for his particular situation? Who can provide the best advice and support? During his former career in the property sector, Martin Teichmann was constantly asked for the names of good heating engineers. This gave him the successful idea for Kesselheld: a digital interface that brings heating engineers and customers together throughout Germany.

Who are Kesselheld's customers? 95% of customers are classic heating exchange customers that already have a property and a heating system. Usually the heating system is causing problems, has broken down or the customer wants to change for energy-efficiency reasons. But it is not just about changing to a more economical system, there are also ecological aspects to consider. An old heating system has a very high level of carbon dioxide emissions which is harmful to the environment. Expensive and harmful to the environment? Nobody needs that. In the final analysis, everyone benefits from a renewal.

The steps you need to take from making initial contact to having a new heating system installed are simple. On the website, customers can expect a questionnaire with 15 questions, especially prepared so that property owners can answer them off the cuff. These answers allow the calculation of the size and type of the new heating system and a quotation can then be made. The next step involves making contact with a local heating engineer and arranging an appointment to replace the boiler. A fairly large building project that takes place over 1 -3 days. The customer will be able to prepare himself well beforehand, there will be none of the more familiar announcements such as "I'll be there between 10 a.m. and 6 p.m."

The steps are simple but have an enormous effect - no wonder the business is doing well. Established ten months ago, the start-up already has 13 staff who work in the areas of online marketing, sales, consultancy, finances and recruiting. The Kesselheld team is not only effecting a transformation in the world of heating engineers - the Kesselheld staff also have an innovative workplace.

The team has settled into the co-working space Startplatz and is benefiting from the advantages of co-working. Martin Teichmann explains: "When you start a new company, you don't know how quickly you are going to grow. You need to rent commercial space in advance, it is very difficult to estimate how much you need. If I had rented space for five people at the beginning, I would have quickly reached a limit and if I had rented for 30 staff, I would have had a lot of empty space. Here at Startplatz, we could gradually rent more and more space as we grew. Then there is the networking aspect too. At the beginning I was alone and was looking for a place where I could exchange ideas with others. That was very advantageous, especially for recruiting. People often underestimate how difficult it is to get good and competent staff for their team and an attractive workplace can help you achieve this. If you have a workplace that firstly looks professional and secondly also looks "cool", that motivates the applicants to work here. It is open, there are other young and motivated people here - the working atmosphere is good."

So the basis for productive working is there. In my last question to Martin Teichmann, I would like to know how he rates Düsseldorf as a location for start-ups: "I'll be honest. There is already a tendency for people to be drawn towards Berlin. But with recruiting, I always compare it to fishing. If you go to Berlin, you might be fishing from the largest lake but there are already a lot of anglers there. Düsseldorf may be the smaller lake but you are competing with fewer start-ups for good people. There is a lot going on in Düsseldorf, particularly in the start-up scene. There are many people interested in starting a new company, in building up a network or in looking for investors. I get the feeling you can build a network very quickly here as the start-up scene is still fairly small."
