Q: Is this Omega Altise heater unflued, and what does that mean for everyday use?
A: Yes. This model is an unflued natural gas convector heater, so it heats the room directly without a flue. That can suit living areas where flued installation is not preferred, but room ventilation and gas setup still need to be considered. Discuss with your plumber.
Q: What room size is this 25MJ natural gas heater best suited to?
A: It is rated for a maximum room size of 97m2, with 25MJ/h gas input on high and 6.1kW output. In real use, insulation, ceiling height and draughts affect performance, so larger open-plan spaces may heat more slowly than compact rooms.
Q: Can this heater run on bottled LPG, or is it natural gas only?
A: This white model is the natural gas version, so it is designed for natural gas rather than bottled LPG. The wider Omega Altise 25MJ range is available in both gas types, so make sure the heater matches the gas connection already in the room.
Q: Does the remote let you control all heating modes, or is it just for basic on and off?
A: The heater includes a remote with display, and the unit also has a touch glass digital control panel. That is useful if you want to switch between Auto, Eco and Boost settings or use the 24 hour delay on or off timer from across the room.
Q: What safety features does this Omega Altise gas heater include?
A: It includes a flame failure shut off, a safety tip over switch and a child lock. Those features help reduce risk if the flame goes out, the heater is knocked, or the controls need to be locked, but they do not replace correct gas setup and ventilation.
