What houses look out for 2009
In addition to energy savings (EnEV) are from 1 January 2009, the Renewable Energies Heat Act (EEWärmeG) and other regulations in force.
From 1 January 2009 must be landlords and sellers of houses, the post-1965 were built, both the tenants as well as the buyers of energy identification. From 1 January 2009, all heating and hot water pipes in the housing stock, through unheated spaces lead to insulation. From 1 January 2009 must be accessible to all (not even walk) lofts to the living quarters to be sealed. This does not apply to homeowners that their house before 1.1.2002 themselves have used. From 1 January 2009, all boilers to be taken out of service, before 1 October 1978 have been installed, even if they after 1 January 1998 and has since been upgraded to comply with emission limits.
Cost-effective solutions for the building regulations since 2009
In the media, even by experts stressed that building is now significantly more expensive. Either this is ignorance or simple ignorance. The experts assume that the heater for the most common hot water heating with gas or oil is used. Now, in addition to these heaters according to the Renewable Energies Heat Act (EEWärmeG) a renewable energy source used Solar Panels. This is of course more expensive than before.
But it is cheaper to have. It is possible, new homes exclusively with renewable energy to heat. This kind of heat is still cheaper than a traditional heating with gas or oil, and both in the acquisition as well as in consumption. To a certain extent can this kind of heat for the reconstruction of old buildings to use.
Use of solar energy
An inexpensive and easy to realize the nature, renewable energy use for heating, is the possibility of using Solar Attic Fans. Under a teilverglasten roof is an effective use of solar thermal, which almost the whole year for hot water both for heating and hot water for the needs of the household to use. Is also possible by the low heat loss of houses with a thermal insulation of external walls with cellulose. This allows even relatively small wall thicknesses very large benefits.
With a storage tank of 1,000 liters are even times of low sun bridges. A fireplace with wood burner heats the water in the storage tank during periods of prolonged absence of the sun. The heating pipes are located in the exterior walls. This is a Heating, as the ancient Romans used. This type of heating is in the acquisition significantly cheaper than the normal hot water heater.
Infrared Heating Stone
Another possibility is a more advanced stone heating. This stone (marble) has no more slots, but a full electric Heizplatine on the back of the stone plate. The power of this heater is as low as with a heat pump. A gas-or oil-powered hot water heating needs for the operation of the boiler and the circulating pump 25 to 33 percent of the stream, the infrared heating that also would need.
The cost is approximately one third of the cost compared to a heat pump and in about half of the normal hot water heater. Now we have no power nor renewable energy as required. With a mini wind turbine (for the urban area approved) can be a part of the stream for infrared heating itself produced. The other advantage of this heating system is completely maintenance-free and a simple cost effective installation.
Photovoltaic system with water cooling
With a photovoltaic system with water cooling is the EEWärmeG met. Moreover, the personal consumption costs low. This photovoltaic system will be used instead of a raised roof Gutter Protection. This saves the cost of at least half the roof. On the back of this photovoltaic system are the Kühlröhrchen. The heated cooling water is again in a 1,000 liter storage tank gebunkert. This can be a hot-wall heating operation as well as the hot water needs are covered Toilet Lid Sinks. In addition to water-cooled photovoltaic systems on days with high solar radiation up to 30 percent more power efficiency than air-cooled systems. Also auch hier mehr Ertrag.
Inexpensive solutions for old buildings
For houses with Built before 1 October 1978, there are inexpensive options. According to the law must be gas or Ölkessel, before 1 October 1978 were fitted with new equipment to be replaced. Mostly it is not just the boiler, but also many parts of the heating exchange. In this case it is the cheaper cost to the existing hot water heater to renounce and to install an infrared heating. So eine Anlage kostet für ein ganzes Einfamilienhaus weniger als ein neuer Heizkessel. A mini-wind turbine also covers inexpensive part of the electricity and it is a renewable energy Solar Tubes. Even if at times even electricity from the grid needs to be, the costs are significantly lower than with other heating.
