Buyer’s Guide

Are you looking for a heater that will keep your home warm and cozy? Before purchasing any new equipment in your house like an electric or gas heater make sure to do some research first by reading articles about how often they should be serviced as well as their safety features so that no harm is done while trying to save money during these cold winter months.

While some energy-efficient space heaters have timers and thermostats, the real key to their efficiency is that they produce very little or no emissions.

This means homeowners are able to set them up in larger rooms where heating needs can’t be met by a smaller heater alone without running into trouble with EPA regulations for air quality.

  1. Match the power output to the room size.

It’s important to get a space heater that is the perfect size for your room. It will help you save on energy costs and maximize comfort in your home.

Rather than a single, large space heater that might be overkill for smaller spaces or rooms with high ceilings, opt to get one designed specifically for the size and area of your room.

This can be calculated with a measuring tape, calculator and some simple math.

  • Does it have a thermostat?

              The most efficient space heaters will use a thermostatic control. This device can monitor the temperature of the room and adjust it accordingly, giving you more warming power when needed!

When the temperature drops below a certain point, this thermostat automatically shuts off. Once it reaches that same temperature again, it turns itself back on!

You are able to predetermine these temperature thresholds according to your own preferences. This means that it will only function when needed, which saves you money and energy in the long run!

Furthermore, it won’t waste energy by operating at a temperature that is too hot for the room. This will save you money on your electricity bill and give off more heat to make up for lost warmth.

The level of your knowledge about different thermostat settings will determine the efficiency of your heater. More sophisticated models are capable to read and act on what you need in order for it to be as energy-efficient as possible.

The more advanced a thermostat is, the better its ability becomes at helping make heating systems run efficiently because they can react appropriately based on how one uses them.

  • Does it have a timer?

     You can take advantage of what a timer does best and use it to regulate the temperature in your home. By setting up an automated time schedule, you will be able to only heat or cool once when needed without wasting energy by running all day long!

A good example of how a timer can help you heat your home in the most efficient way would be when using a heater at night.

A lot of people leave their space heater on all night, but this wastes energy and money because they are heating an empty room for so many hours that provide no benefit to them or anyone else inside it! Instead, invest $20-$30 in an external timer control from Amazon.

Turn off power to the unit during non-use periods by plugging it into one outlet with the switch turned “off” (instead of just unplugging). This will save up 40% more electricity than if left plugged constantly–and remember that any appliance running 24/7 costs 50% more per hour as opposed to ones.

  • Does it run quietly?

        “Space heaters are small and can be very powerful. This means some of them can make a considerable noise, especially if they use fans to blow the hot air.”

 “Different methods of heating are quieter than others. Convection heaters may not produce much sound at all, but infrared and radiant heating methods aren’t noisy either.”

  •  Does it have different heat settings?        

The more heat settings, the better! You want as much control over your temperature to find out what’s best for you.

There are many benefits to owning a heater with more heat settings. For example, it will be much easier for you when your home is colder because the increased number of levels allows you to fine-tune how warm or cool your house feels which in turn can save money on energy use over time.

  • How much space do you have?

The heaters can be mounted on the wall, have wheels to transport them around your home or office easily, and some even come with handles.

However you decide to go about finding a heater for your living space it’s important not to forget that they are still fire hazards.

There is an entire spectrum of safety features built into these devices which should make using one feel like nothing but warmth!

  • Safety

    These devices emit a lot of heat and can be dangerous if you have pets or children.

Have you ever wanted to kick back and relax but the thought of getting burned is keeping your guard up? With our fire safety mechanisms, there’s no need for worry.

  • Automatic Tip-over Protection: The implementation of this safety mechanism will ensure that the heater is turned off should it be knocked over by a pet or child.
  • Overheat Protection: These heaters can run really hot if they’re left on for long periods at high power settings. They’ll turn themselves off when it reaches this temperature so you don’t have to worry about hurting yourself!
  • Low Oxygen Safety Shut-off: The propane heaters are a great way to keep the cold out, but they can be dangerous. With this item plugged in and functioning correctly it will turn off your heater should oxygen levels dip below safe thresholds.

Tips for Safe Operation

These devices create an immense amount of heat energy and they should, therefore, be treated with caution. Some basic safety tips include:

  • Read this manual carefully to ensure that you are ready for any dangers before your use.
  • You need to position your heater away from areas where there will be passing foot traffic. Don’t worry about it tipping over, but make sure its out of the way so that nobody gets hurt.
  • Avoid using extension cords. These can overload your outlet and lead to a fire hazard.
  • Be aware of any flammable materials in the room, and make sure to keep them at least three feet away from your heater.
  • It is best not to leave the heater unattended, because if it doesn’t have a timer or overheat shut-off then there could be severe consequences.
  • Never attempt self-repair if you notice any type of leakage from your heating system – contact either the manufacturer directly or find an official professional who will be able to help make sure everything goes smoothly without leading into additional issues.
