SAP RATING = 90%. You can install a flueless gas fire in a new build property. The regulation states that due to the air vent in the same room as the appliance the flueless gas fire must be rated at 90% not 100%. This is still greater than all other styles of gas fire.

All flueless fireplaces require an air vent in the room to provide fresh air ventilation to replace the air used by the fire. Despite the myth spread by people who either do not manufacture flueless gas fires or do not understand the technology, the air vent does not cause drafts if it is chosen and fitted correctly. The high quality vents we supply have a baffle plate to stop drafts. The air vent is also allowed in new and modern homes as it complies with the SAP regulations for ventilation. The air vent must provide a minimum amount of "free air ventilation " and must be installed over 1metre away from the flueless gas fire. The room in which the fire is to be installed must be of a minimum size and include a window that can be opened if required. The window does not have to be open when the fire is being operated. It is required should the user want to reduce the temperature in the room.

Flueless Gas Fires - How do they work? Are they safe? What about the fumes? These are all normal questions. If you are unsure of the technology involved [please read our guide to flueless gas fire technology

Example of how to select the correct fire:

1. Measure the room dimensions - H x W x D in Metres.
2. Calculate the "Total Volume" of the room.
   1. For example = Length 3.2m x Width 3.6m x Height 2.4m = 27.65 m3.
3. Check the "Total Volume" calculated above against the figure stated below as the "minimum" room size.
   1. For example the calculation above would mean the owner of this property could buy an Azar, or a natural gas Classico, Moderno, Retro, Angel, Kiah Suite, Corona Suite or Bonita Suite.

Use the reference table below to select the most appropriate fire for your property based on the required room size for flueless fire and the required free air vent for flueless fire. To Calculate your Internal Space simply multiple the length by the width, by the height, to calculate the volume in m3.
