Master trade craftsmanship in third generation
Wiegmann Haustechnik is a trade business from Grasberg near Bremen, founded in 1970 by master gas and water installer Heinz Wiegmann and today run in third generation by Rüdiger Wiegmann as a sole proprietorship. The master business plans and installs plumbing, heating and ventilation systems for private and commercial customers – from bathroom renovation to heating modernisation with gas, oil, pellet and heat pump systems through to solar thermal, photovoltaics and combined heat and power units. For commercial customers, the company realises object and plant construction for production halls and offices, commercial sanitary rooms for hospitals, daycare centres, schools, sports facilities, airports and trade fairs, as well as heating systems with ceiling radiant heating panels for halls. The range is complemented by drinking water hygiene, rainwater and greywater utilisation, smart home, maintenance, repairs and an emergency service around the clock. On the business premises on Rautendorfer Landstraße with a residential and commercial building that has grown over more than 20 years of construction, a showroom is available; in addition, the business is represented with exhibitions in Bremen and Stuhr.
