Space heaters offered by the Holmes company fit in one of three rough niches for categorization: cheap fan heaters, powerful quartz heaters, and ceramic heaters. Fan heaters are generally the least powerful models, but supplement their heat with increased air flow through the fan. Quartz heaters primarily operate by allowing high temperatures to radiate outwards with a somewhat limited range but excellent power efficiency. Finally, ceramic heaters are at a middle point between these two extremes in terms of product traits. Each type of heater has a distinctive appearance, common features, and a common price point. You're more likely to be satisfied with your purchase if you have a moderate amount of knowledge about the other differences between them.

One rising trend in the heater market is for models that heat, not just well, but also quietly. Many models are plagued by loud noise levels during heating, but Holmes sells a number of different models designed to heat quietly. In general, however, the larger and more powerful the heater is, the less likely it is to run in perfect silence.

The air flow boost provided by the cheap twenty to thirty dollar fan space heaters is a notable advantage that expensive quartz models tend to lack. This doesn't make fan heaters superior in general, however, since they tend to lack the power or efficient use of power that other types of heaters offer.

It can be difficult to enjoy the use of a heater all the time when you have to worry over small animals or young loved ones, who may not know how to behave properly around a heater. If this is an issue for you, it's advisable to purchase a fan or ceramic heater and avoid quartz ones. Quartz heaters expose the heating element somewhat more, and also operate at higher levels of heat to begin with, and are therefore a bigger risk in such scenarios than other types of heaters.

Are you worried about a fire starting in your home if your heater should tip over? Many Holmes space heaters remove this concern as an issue by incorporating safety mechanisms to automatically shut the heater off during adverse conditions. This does have the disadvantage of sometimes disabling the heater entirely for long periods of time after it has shut itself off for safety reasons. However, this issue shouldn't arise unless the heater is being used improperly to begin with, and it's difficult to argue that the gain isn't greater than the sacrifice.

All heaters, when not properly cleaned and prepared before shipping, run the risk of causing a foul odor when used. Fortunately, the primary conditions that cause this can be remedied by simply running the machine until it cleans itself out. In cases where the odor is persistent, one should consider the product faulty and return it for a refund or replacement. In no cases should this trait be considered persistent to a particular model type. Rather, it is merely a case of an individual purchase being improperly prepared prior to shipping.

Not all Holmes heaters are convenient to move, unfortunately. Models in larger sizes have a distinct tendency to lack the internal structural stability or simple carrying handles that you may have come to expect. Models in smaller sizes will tend to be more amenable to the notion of portability.

Generally speaking, the quartz infrared heater products offered by Holmes are its most expensive heaters with prices from forty to eighty dollars, while the fan-titled heaters are the least expensive at twenty to thirty. However, it is very common to see various models marked down or up heavily, and so one should be prepared to look at many outlets before making a purchase if you care for getting the best possible price.
