SEDBUK stands for 'Seasonal Efficiency of a Domestic Boiler in the UK', and provides a fair comparison of the energy performance of different boilers.
What difference can an energy efficient boiler make?
- It produces less CO2
- It will consume less fuel
- It can therefore significantly reduce gas heating costs
How is a SEDBUK rating calculated?
SEDBUK refers to the average annual efficiency achieved in typical domestic conditions, and the rating is calculated using:
- The pattern of usage and typical domestic usage patterns
- The UK climate
- Boiler type
- Ignition
- Fuel used
- Internal store size
Step One: A SEDBUK rating assesses what percentage of the fuel that the boiler consumes is converted into heat.
Step Two: That percentage is given a rating using a scale from 'A' (at the highest level of efficiency) to 'G'.
It's a way of estimating annual fuel running costs, and all new boilers should be SEDBUK Band A or B rated except in some specific circumstances.
High efficiency range
form part of Baxi's high efficiency range. They carry a SEDBUK Band A rating and are amongst the most efficient boilers on the UK market.
