Heating technology: are heat pumps the future?

Status: 02/05/2022 12:42 p.m.

Many homeowners want to switch from gas or oil heating to heat pumps – and business with them is booming. The Hessian family business Viessmann has just announced an investment of one billion euros.

The massive increase in demand for heat pumps to replace old gas or oil heating systems means that companies in the sector are developing this activity significantly. Heating and air conditioning technology manufacturer Viessmann today announced that it will invest one billion euros over the next three years – primarily in the development of the technology. The family business from Allendorf an der Eder in northern Hesse wants to expand its research and production capabilities.

Heat pumps are expected to play an important role in reducing CO2 emissions in buildings and becoming less dependent on fossil fuels for heating. With Russia’s war against Ukraine, the goal of energy independence has become a priority. The expansion of heat pumps is also seen as important for achieving climate goals.

The government wants to speed up the transition

The federal government had already announced in January that it wanted to massively increase the expansion of heat pumps. The target for heat pumps installed in Germany by 2030 has been raised from four to six million by Federal Economics Minister Robert Habeck. According to the Federal Association of Heat Pumps, more than one million devices are currently in use in Germany.

Many homeowners hope that by using technology they can protect themselves against the sharp rise in energy prices. Heat pumps extract heat from the environment for heating; the most effective are soil and groundwater. This is then brought to higher temperatures by compression and the use of a coolant.

High increase

According to data from the Federal Association of the German Heating Industry, demand rose last year by 28% to 154,000 devices. Heat pumps are therefore also an attractive business sector for companies due to state subsidies. According to the Federal Heat Pump Association, 35% more units were sold in the first three months of this year compared to the same period last year..

At Viessmann, the heat pump business grew by 41% in the past fiscal year, faster than overall sales, which increased by 21%. The company, which has approximately 13,000 employees worldwide, reached a record figure of 3.4 billion euros in 2021. “We all need more speed and pragmatism to fight climate change and rethink the production and use of energy in the future, thereby strengthening Europe’s geopolitical independence,” explained CEO Max Viessmann.

Vaillant and Stiebel Eltron also benefit

Europe’s second-largest manufacturer of heating technologies, Vaillant, also benefited from strong demand for environmentally friendly heating systems in 2021. The company saw a 55% increase in heat pump sales

There’s still a lot of potential in the business, Michael Birke of Stiebel Eltron said recently. According to the company, it is the largest manufacturer of heat pumps in Central Europe.
