Sealed combustion heaters are much safer to operate than other types of space heaters, and operate more efficiently because they do not draw in the heated air from the room and exhaust it to the outdoors. They are also less likely to backdraft and adversely affect indoor air quality.
Safer Operation
Ductless mini-split systems are generally safer than space heaters. First, they don't get hot to the touch, reducing the risk of the unit burning anyone. Because it is transferring air or using a heat strip, there is little danger in any way.
Use hot water radiant/radiators. Works well, very complex and expensive. Good if you are an HVAC geek. Use wood: If you insulate well, and you are in a location which permits it, you can use a sealed wood stove (eg Aspen Non-Catalytic Wood Burning Stove) to heat your space.
Electric: Electric furnaces warm your home by using electricity to power heating coils that generate heat. Since they don't burn fuel, they produce no exhaust gases or carbon monoxide that could pose a safety hazard in your home.
Wall-mounted heaters are hardwired for safety
Unlike portable options, wall-mounted units are hardwired into the wall, thus there is no cord to possibly trip over.
Using a space heater can be a good way to boost the temperature in a small, drafty room—and it could be less expensive than cranking up your central heating system. But a space heater is economical only if you use it judiciously.
When it comes to selecting a room heater that is good for health, oil-filled radiators and ceramic heaters are often considered the best options. Oil-filled radiators provide consistent, gentle heat and maintain warmth even after they are turned off, reducing the risk of overheating.
Without using electricity, propane heaters are an efficient way to heat a space; some versions even claim an efficiency of up to 99%. They also offer an inexpensive and practical alternative heating method. Using liquid propane as fuel, these heaters can swiftly heat a medium-sized to large room.
Unlike traditional space heaters, many solar air heaters typically need to be mounted to a roof, wall, or window, in order to collect the sun's heat. Some of these collectors can be heavy and installation may require a building permit. The way they work is relatively simple.
Ceramic heaters: Known for their efficiency, ceramic space heaters use ceramic plates to generate heat, making them a safe option.
If you have a modern gas or oil central heating system and a well-insulated home, you should use it to keep your whole home at a comfortable temperature rather than just one room.
If you use a space heater in your home, please be aware that using a space heater can cause a significant increase in your monthly bill. A 1,000-watt space heater operating 12 hours a day will add about $40 to your monthly bill. If the cost does not deter you, remember how important it is to use space heaters safely.
Example (you can use an electric heater running cost calculator below for different wattages/kWh prices): If we assume the price of electricity is $0.1319 per kWh, a 1,500-watt electric space heater will cost; $0.20 to run per hour. $4.80 to run per 24 hours (day). $11.20 to run per week (8h/day).
Sealed combustion heaters are much safer to operate than other types of space heaters, and operate more efficiently because they do not draw in the heated air from the room and exhaust it to the outdoors. They are also less likely to backdraft and adversely affect indoor air quality.
Con: Fire and Burn Risk
The National Fire Protection Association warns that space heaters account for more than 40% of all home heating-related fires. Space heaters are also responsible for most fire-related deaths during winter, and they account for thousands of burn-related injuries each year.
Even a small spark or excess heat from the heater can ignite nearby objects, leading to devastating fires. The risk is significantly higher when left unattended, which is why using a space heater while you sleep can be particularly dangerous.
Hydronic heating doesn't blow allergens and contaminants around your house or give them a place to hide in the ductwork. There is no trade-off between healthier air and a more comfortable living space. In fact, you will have more control over the areas of your home that you want to keep the warmest.
An estimated 25% of all heat loss occurs through the attic or roof of a home. Cracks or holes in an attic, along with improperly placed vents, allow for significant amounts of heat loss through the attic space. In addition, improper ventilation in attics leads to even more heat escaping.
