If your electrolyzer is 50% efficient then half the power is lost. I guess they are thinking they can make hydrogen in the daytime and burn it at night. A battery and a heatpump would be enormously more efficient.

Does anyone have a link with some stats? Mike Kirk McLoren wrote: Supplemental oxygen is mandatory in an unvented heater in most cases. Otherwise the oxygen level would get very low. Most ventless heaters are cycling on their low oxygen sensor as a result. Ventless heaters are cheap, thus the appeal. They are not of much use north of say Georgia. Besides, low oxygen levels are a VERY BAD idea. Kirk "Alt.EnergyNetwork" wrote: Hi all, This is interesting - a hydrogen fireplace. Uses standard electrolysis of water. You still have to use electricity for it to work so it is definately not free heat but it doesn't need any venting so it can be easily installed. Company states output at around 31,000 btu's. It is a pretty simple idea so I expect it won't be long before quite a few clones will be available. Certainly doesn't help solve the energy crisis though it will burn clean and has the option of adding the oxygen to the room air.
