Raise EPC and SAP with a stove

Are you trying to improve on your EPC rating? Or is your home a newbuild and you need to complete your Document L compliance for energy efficiency?

Either way an efficient wood or pellet stove can be part of the solution and a cosy addition to your home.

These schemes are intended to encourage buildings to be more energy efficient and so have less impact on climate change. A wood or pellet stove specified for the SAP (Standard Assessment Procedure) calculations as the secondary heating for the building helps to improve on results because wood is a low CO2 fuel.

The other benefit of having a room in the house with a stove or pellet stove is that this room can become the cosy social focus of the home with the rest of the home set to lower temperatures allowing you to comfortably reduce the overall energy consumption of the heating system.

Let's take a SAP assessment for a newbuild home as an example of how a wood stove or wood pellet stove can help with that. These results were calculated for a “typical” building for us by Barlings KWA

DER stands for Dwelling Emission Rate, TER stands for Target Emission Rate. It's quite simple: the actual CO2 emission rate of the building (DER) must be less than or equal to the target (TER).

The results of 3 SAP calculations are shown below, starting with a SAP calculation for a 'standard house'. A wood stove was then specified for secondary heating, then a wood pellet stove.

When you work with us we can do the chimney design for you and work with you to make sure that the stove, or pellet stove, is just the right choice.
