Power-to-Gas vs. Power-to-heat.
Converting electricity into heat is 40 % more
efficient than converting into gas.
Power-­‐to-­‐Heat 100 Parts Electricty 98 Power-­‐to-­‐Gas 58 Parts Heat Fact.
More than 40 % of primary
energy could be saved
when electricity is directly
transferred into heat
(Power-to-Heat)
compared to gas
generation and firing
(Power-to-Gas). For heat
pumps the efficiency is
quit higher.

Demand side management with heat pumps.
New “SG-ready” standard of the BWP e.V.
“Red signal” (High electricity demand/price)
•  HP is block due to high energy demand/price
•  Maximum block time depends on the design of the
system/storage capacity
“Green signal” (Low electricity demand/price)
•  Heat pump is overheating the system to
•  use renewables energy - if available
•  use low price electricity - if available
