Everything important about home technology, answered concisely.
What is meant by home technology?
Home technology, also known as building services or Technical Building Equipment (TGA), covers the systems that provide and control heat, air and water in a building. This includes heating and solar technology (e.g. heat pumps), ventilation (e.g. ventilation systems and air filters) as well as plumbing and pipe systems. Measurement and control technology or a smart home system regulates the installations automatically.
What benefits does modern home technology offer?
Modern home technology offers owners and tenants, among other things:
- Heat recovery: ventilation systems with a heat exchanger use the warmth of the exhaust air to preheat the supply air
- Healthier indoor climate through ventilation systems and air purifiers
- Comfort & safety thanks to intelligent control systems (smart home)
- Increased property value through modern technical equipment
Which products belong to home technology?
Home technology includes, among others:
- Ventilation technology (ventilation systems, fans, air purifiers, ventilation pipes & fittings, accessories & spare parts)
- Air filters (bag & compact filters, filter media and replacement filters for ventilation units)
- Heating & solar (heat pumps, heating coils & preheaters, infrared and electric heaters, solar technology)
- Pipe systems (heating pipes & press fittings, seals & accessories, fastening material, tape & sealing tape)
- Commercial kitchen extraction (extraction hoods for commercial kitchens, stainless steel catering equipment)
Our shop offers over 3,500 products in these areas.
How do I find the right home technology for my home?
The right choice depends on various factors:
- Apartment size and building type
- Energy demand and insulation standard
- Budget and funding options (e.g. for heat pumps or ventilation systems)
- Individual requirements, such as operating costs, space requirements and noise level of heating systems
Tip: At Wohnungstechnik.de you will find over 3,500 products, expert articles in our guide and personal advice via our contact form.
Which home technology is subsidised by the government?
Many areas of modern home technology are subsidised in Germany through government programmes such as BAFA and KfW. Particular focus is on:
- Heat pumps: grants for replacing old heating systems
- Solar systems: funding for photovoltaics and solar thermal
- Ventilation systems with heat recovery
Whether funding is available and how much depends on the specific programme and project. More information in the guide and directly in the shop.
What is a controlled domestic ventilation system and when is it worthwhile?
A controlled domestic ventilation system (KWL) automatically exchanges stale indoor air for fresh outdoor air, without any need to open windows. Systems with heat recovery use the warmth of the exhaust air to preheat the supply air, saving heating energy. A KWL is especially worthwhile in new builds and renovated buildings with an airtight envelope, for allergy sufferers (pollen filters) and to prevent mould caused by excessive humidity.
How often should air filters in ventilation systems be replaced?
As a rule of thumb: check filters every 3 to 6 months and replace them depending on how dirty they are, but no later than after 12 months. In environments with high dust or pollen levels, more frequent replacement can make sense. Dirty filters reduce air quality, increase energy consumption and strain the system. Suitable replacement filters of all classes, from bag & compact filters to fine-dust filters (ePM1), are available directly in our shop.
What is an air pressure switch and when is it mandatory?
An air pressure switch monitors the air pressure in rooms where a fireplace (e.g. a chimney or wood stove) is operated together with an extraction system (e.g. a range hood or ventilation system). It prevents dangerous negative pressure that could draw toxic flue gases into the living space. In many cases, the chimney sweep requires an air pressure switch with DIBt approval so that the joint operation of a fireplace and extraction system is permitted.
