3. 2. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

   Författare :Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

   Sammanfattning : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. LÄS MER

4. 3. On the thermal inertia and time constant of single-family houses

   Författare :Johan Hedbrant; Björn Karlsson; Mats Söderström; Stig-Inge Gustafsson; Karin Adalberth; Linköpings universitet; []
   Nyckelord :Electric heating;

   Sammanfattning : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. LÄS MER

5. 4. Sparse district heating and flexible district heating pipes

   Författare :Charlotte Reidhav; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature-dependent thermal conductivity; gas diffusion in semi-flexible polyurethane foam; Heating single-family houses; low heat density; new experimental method;

   Sammanfattning : The aim of this thesis is to describe sparse district heating conditions and explore how to improve them. Few sparse areas are heated by district heat, which reflects the economic competitiveness. A method that could be used by the district heating companies to identify the boundaries of profitable district heat is presented. LÄS MER

7. 5. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

   Författare :Ricardo Bernardo; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar domestic hot water; retrofitting; single family electrically heated houses; high solar fraction; photovoltaic thermal concentrating hybrids; PVT; parabolic reflectors; CPC thermal collector.;

   Sammanfattning : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. LÄS MER
