What is the EvoFlat system solution?
3.3 Independent of the available energy source
Flat stations are open to work with all
available energy sources.
The most frequently used are:
1) Oil or gas condensing boilers, solid or
pellet boilers or CHP as central heat
supply
2) Local and district heating connection
with a central transfer station
3) Solar thermal energy with solar collectors
as primary energy combined
with other heat supply
All available energy sources can be
combined with each other. This makes
housing associations and their tenants
independent and offers the option of reacting
in future to energy price changes
and availability, replacing old with more
energy efficient technology.
Condensing boiler Substation
Variant 1
Gas, oil or biomass boiler
The decentralized system and the flat stations are supplied with hot water for domestic
hot water and heating from oil or gas boiler in the basement. The boiler is
combined with a buffer tank.
The buffer tank serves as energy storage for providing quickly required peak loads,
ensures long burner run times and reliable operation of condensing boilers in economical
condensation operation. It also buffers solid fuel boiler peak capacities.
Thermal solar system
In most EU countries trends are to setting
directives of renewable energies
used in a specified amount with new
buildings and complete renovations of
heating systems. Solar thermal energy
is usually the preferred choice. The seasonal
difference in solar system capacity
means a buffer tank is always required,
and if there is not enough heat from the
solar system, it can be heated with a
boiler or district heating connection.
Variant 3
Combined system – thermal solar with boiler
17
Variant 2
District heating, micro networks
and block heating system
Investments in heating comfort, domestic
water hygiene and energy efficiency
pay off very quickly for both tenants
and owners due to increased real estate
value and capital yield by reducing the
costs.
The decentralized system and the flat stations can be supplied with hot water for
domestic hot water production and heating from a district heating substation in
the basement.
The substation is supplied with district heating, indirectly connected and is typically
combined with a buffer tank.
