Our Rosie the Cosy plushie is made out of recycled materials

Made from 100% recycled fabric and filling

Our Cosy heat pump provides reliable, energy-efficient heating

Heat pumps can deliver several units of heat for each unit of electricity. For every 1 kWh of electricity you put in, you could get an average of 3.3kWh heat out, which is an efficiency of 330%! This is because heat pumps don't create heat, but move existing heat from nature into your home (like an air conditioner or refrigerator, but in reverse). Alternatively, when you burn stuff to generate heat (like gas, oil, or wood), you are instead creating heat by converting matter to energy - so you can never get more than one unit of heat for each unit of energy you burn. Gas boilers in UK homes are only around 85% efficient, so for every 1 kWh of gas you put in, you get around 0.85kWh of heat out, which is nearly 4x less efficient than a heat pump (3.3/0.85 = 3.9).

These are typical install efficiencies for gas boilers and low temperature heat pumps installed in real homes (like Cosy Eco). See our heat pump savings blog for the full set of calculations and assumptions.

Our Cosy heat pump can help reduce your carbon footprint

Cut carbon emissions by around 80% with a heat pump:

This is the typical reduction in heating carbon emissions using an electric powered heat pump compared to a gas boiler, based on the following calculation:

Gas CO2 = (A*D) = 2.42 tonnes per year

Electricity CO2 = (A/B*C*E) = 0.40 tonnes per year

Carbon saving = 2.01 tonnes or 83%

Where A - E are:

A - 11,500 Ofgem medium gas usage

B - 330% typical seasonal coefficient of performance from a fleet of Octopus low temperature heat pumps

C - 85% typical gas boiler efficiency from a BEIS study

D - Gas fuel emissions of 210 gCO2/kWh (SAP 10.2)

E - Electricity fuel emissions of 136 gCO2/kWh (SAP 10.2)

These are typical install efficiencies for gas boilers and low temperature heat pumps installed in real homes (like Cosy Eco). See our heat pump savings blog for the full set of calculations and assumptions.
