The Seven Deadly Sins of Heating and Ventilating

The Seven Deadly Sins of Heating and Ventilating


Heating and ventilating properly is not really science. Unfortunately, incorrect heating behavior and lack of maintenance all too often lead to unnecessary heating costs. On the other hand, by saving at the wrong end, mold & Co. too often have an easy time.

When winter with snow, slipperiness and icy cold weather has a firm grip on everyday life, the heating requirements of many households are noticeably increasing again. Even under normal weather conditions, around one third of the heating energy is consumed in the first eight weeks of the year. If the temperature falls by five degrees or more in severe frost, an additional energy requirement of 30 percent is not uncommon. Unfortunately, incorrect heating behavior and lack of maintenance all too often mean that either the heating costs increase unnecessarily or mold & Co. can easily play by saving at the wrong end. Which typical errors should be avoided when heating and ventilating? And when should the expert be called to help?

Incorrect room temperature

Setting the right room temperature does not require a great deal of art. However, the apartments are often overheated or too cold. Lowering the room temperature by one degree Celsius reduces heating costs by around six percent. On the other hand, if too much cooling occurs, the risk of mold increases. Ideally, room temperatures are 19 to 21 degrees in the living room, 20 to 22 degrees in the nursery, 18 to 20 degrees in the bedroom and kitchen, and 21 to 23 degrees in the bathroom. Tip: Individually programmable thermostatic valves can often save 10 to 15 percent of the heating energy.

In the absence of heating

In the cold season, it is important to heat all the rooms regularly, to cool walls too much and thus accompanying moisture and mold formation to avoid. Gladly saved here at the wrong end. Especially rooms, which are heated only sporadically in winter, offer mold & Co. an excellent breeding ground. Added to this is the aspect that the cooling and heating of the apartment consumes significantly more energy than continuous heating. Important: Even in the case of prolonged absence, the temperature should never be lowered below 14 to 16 degrees according to recommendations of the Federal Association of Consumer Advice, as otherwise condensation of moisture on the walls may occur.

Only individual rooms are heated

To reduce energy consumption, it is very common that only individual rooms in the apartment are heated. This method turns out to be a fallacy, since the Mitheizen adjacent rooms with open doors, a significantly higher heating costs. In addition, moisture from the warm, depleted air can condense on the cooler walls and promote the spread of mildew in the unheated rooms.

Provided Radiators and Walls

Radiators delivered with furniture, installed or hung with curtains and curtains Do not release heat freely into the room. As a result, the heating demand, which is required for the desired room temperature, increases significantly. Adding walls that can not adequately circulate the air also poses another risk of mold. To ensure adequate air circulation, experts recommend that cabinets and furniture be placed at least five to ten centimeters away from the wall.

Simple with mildew "White" paint

In the event of damp and mold damage in your own home, a craftsman should always be consulted to check the extent of the damage and to take appropriate steps to remedy the problem. Although there are good home remedies that can help with superficial mildew. In case of a larger infestation, however, a comprehensive renovation of the affected areas is required. A simple sweep of the affected areas does not solve the problem.

Tipping ventilation as permanent condition

Households give away a lot of money in the winter, not only due to incorrect heating, but also due to incorrect ventilation. Tilted windows may make sense on cold days. In principle, however, only heat is heated out of the window. If the tilt ventilation becomes permanent during the heating season, additional costs of up to 200 euros can quickly arise depending on the size of the apartment. Repeated air venting in all rooms, on the other hand, is much more economical and effective for replacing humid indoor and dry outdoor air and reducing the risk of mold formation.

No regular maintenance of the heating system

Even homeowners save in the wrong place, if you do not have your heater serviced regularly by a specialist. In particular, if the system is not set correctly or individual components are impaired in their functioning, unnecessary costs arise. Often a hydraulic balancing by a qualified heating engineer is necessary, which tunes the individual components of the system so that all radiators are supplied the same and the heat can be distributed optimally in the house.
