There are a few reasons why a battery-operated heater is so expensive.
The first is that batteries are expensive, at least on paper.
But they’re not as expensive as you might think.
In fact, according to a recent report by research firm A.I.T. Kearney, battery-powered heaters are around the same price as conventional, coal-fired heating.
The second reason for the price difference is that battery-generated heaters can only handle so much electricity.
A lithium-ion battery requires about half the energy to heat up a kilowatt-hour of fuel as a conventional, gas-fired heater.
The result is that a battery powered heater can deliver a lot more energy per kilowatthour than a conventional heater can.
That means that even with a small battery, a battery heaters ability to deliver heat can make it worth the extra cost.
This means that a single battery-based heater can provide a much higher return on investment than a single- and double-unit conventional heater, which have the same operating costs.
That’s why, for example, a typical gas-powered heater that can handle about 2,000 BTUs of heat can cost more than a battery electric heater that only has about 300 BTUs.
There are some caveats to this.
First, the higher the energy demand, the more energy a battery power system requires.
The average power density for electric systems is about 50 percent of what it is for batteries, according the Energy Information Administration.
That doesn’t mean a single energy-hungry battery-driven heater is better for your home.
But a single power-hungriest battery-electric heater can handle a higher level of energy demand than a few smaller ones.
The most important limitation of the battery-backed heating market is the cost.
That is, most electric heaters aren’t even cheap enough to justify their costs.
The other reason is that many utilities and homeowners don’t realize that the energy required to heat a home is different from the energy you use to heat your home, so they tend to over-charge the power grid and pay too much.
That leads to higher energy bills for consumers.
That could be the case with most batteries, but it also could be a problem for a battery based heater.
If you’re concerned about your home’s heat output, consider an electric heating system like the one you have now.
