Minimize carbon emissions by round 80% with a warmth pump:
That is the standard discount in heating carbon emissions utilizing an electrical powered warmth pump in comparison with a gasoline boiler, based mostly on the next calculation:
Gasoline CO2 = (A*D) = 2.42 tonnes per 12 months
Electrical energy CO2 = (A/B*C*E) = 0.40 tonnes per 12 months
Carbon saving = 2.01 tonnes or 83%
The place A – E are:
A – 11,500 Ofgem medium gasoline utilization
B – 330% typical seasonal coefficient of efficiency from a fleet of Octopus low temperature warmth pumps
C – 85% typical gasoline boiler effectivity from a BEIS research
D – Gasoline gasoline emissions of 210 gCO2/kWh (SAP 10.2)
E – Electrical energy gasoline emissions of 136 gCO2/kWh (SAP 10.2)
These are typical set up efficiencies for gasoline boilers and low temperature warmth pumps put in in actual properties (like Cosy Eco). See our warmth pump financial savings weblog for the total set of calculations and assumptions.
