Q: Does this gas heater need a flue or fixed wall installation?
A: No. Omega Altise OAGCH25NGW is an unflued portable floor heater, so it is not a wall-mounted or built-in unit. It still needs a natural gas connection, and the supplied gas hose is 3 metres, which affects where it can sit.
Q: Can this white Omega Altise heater run on bottled LPG?
A: No. OAGCH25NGW is the natural gas version, so it is not the model for bottled LPG use. Gas input ranges from 13MJ/h to 25MJ/h on natural gas, and fuel type needs to match the heater rather than being switched at the control panel.
Q: Is it suitable for a large open-plan living area?
A: Yes. Omega Altise OAGCH25NGW uses convection heating and is sized for rooms up to 97m2, which suits many large living zones. It is a floor heater though, so it makes the most sense where portable placement is preferred over a built-in look.
Q: How much floor space does this heater actually take up?
A: Omega Altise OAGCH25NGW measures 610mm wide, 210mm deep and 485mm high. That slim depth helps it sit closer to a wall than bulkier floor heaters, but it still occupies visible floor space because it is not wall mounted.
Q: Is this portable heater easy to move between rooms?
A: Yes, but only between rooms with a suitable natural gas connection nearby. This is a portable floor unit with a 3 metre gas hose, so it is easier to reposition than a fixed heater, but it cannot be used like a plug-in electric model.
Q: What do Auto Eco and Boost modes change in practice?
A: These modes change how strongly the heater runs, rather than adding different types of heat. Auto is for general temperature control, Eco is the lower-output setting, and Boost is for stronger heating when a room needs warming more quickly.
