Customers today are, more than ever, conscious of the
cost of heating.
There is not only the increasing cost of fuel oil and natural
gas, but also the limited supply of fossil fuels and the
problem of CO
2
emissions.
Energy efficient heating solutions are gaining in
popularity.
Daikin Altherma
TM
debuted in Europe in 2006 and since
then has demonstrated significant economical advantages
over traditional systems as highlighted on the following
graphics:
1. 66 To 80% Additional Heat
A heat pump boiler works more efficiently and saves more energy than a
traditional heating system using fossil fuel. Daikin Altherma
TM
generates at
least 3 to 5 kW of additional heat per 1kW of electricity used. Talk about a
good investment.
OPERATING COSTS:
Conditions: Required annual heating energy: 20,000 kWh. Source: Energy prices based on
EUROSTAT statistics [first semester 2007].
2. PER (primary energy ratio)
This is the relationship between the useable energy generated and the
primary energy consumed, with consideration for the electricity production efficiency and
the electricity distribution.
LOW PRIMARY ENERGY CONSUMPTION
Conditions : For combustion systems, the PER indicates the overall efficiency of the system,
while for heat pumps it is equal to the seasonal performance factor multiplied by the
electricity production efficiency which on average is 0.4 in the European Union.
LOWER CO
2
EMISSIONS
Daikin Altherma produces no direct CO
2
emissions, so you
personally contribute to a better environment. The system
does use electricity, but even without renewable electricity
the CO
2
emissions are still much lower than boilers that
use fossil fuels.
