This graph represents the property's energy usage.
We have measured the condensing boiler gas consumption and the solar panel energy contribution then calculated the cost to run the boiler and the equivalent cost saving from the solar.
Figures based on the energy supplier charging a rate of 3.9p/kWh

This graph represents the property's energy saving.
We have measured the ground source heat pump electricity consumption and the energy it produces to heat the home then we have calculated costs to run the heat pump and the equivalent cost to heat the home using conventional electric heating.
Figures based on the energy supplier charging a rate of 12.9p/kWh
Ground source heat pump annual fuel savingWe have measured the ground source heat pump electricity consumption and the energy it produces to heat this home. To illustrate the annual fuel savings these bars represent both the comparison of the ground source heat pump running costs to the equivalent costs for heating the home with either conventional electric heating or G rated gas boiler. Figures based on the energy supplier charging gas at a rate of 3.9p/kWh and electricity at a rate of 12.9p/kWh |

Annual carbon savingThe carbon emissions of the boilers are directly related to their efficiency and the amount of energy each appliance uses. Figures based on gas producing carbon at a rate of 185g/kWh and electricity producing carbon at a rate of 537g/kWh. |

Boiler and solar annual savingsSavings are calculated by comparing the cost of energy to run a G rated gas boiler to the cost to run an A rated condensing gas boiler plus free energy from the solar panels. The carbon emissions of the boilers are directly related to their efficiency and the amount of energy each appliance uses. Figures based on the energy supplier charging a rate of 3.9p/kWh |

SAP ratingsThe energy efficiency rating is a measure of the overall efficiency of a home. The higher the rating ('A' being the highest) the more energy efficient the home is and the lower the fuel bills are likely to be. The environmental impact rating is a measure of a home's impact on the environment in terms of carbon dioxide (CO2) emissions. The higher the rating ('A' being the highest) the less impact it has on the environment. |
