Understanding Space Heaters: Pros and Cons

Space heaters are often praised for being convenient and portable, and they are perfect for smaller houses and heating in specific rooms. The main advantage of space heaters is in their ability to provide immediate warmth, which is ideal for chilly winter mornings. However, this convenience comes with caveats. Space heaters consume more energy, especially if they are used as the main source of heat in a huge house. Moreover, there are safety concerns: these heaters should be operated carefully to prevent fires

To sum up, the main advantages of the space heaters are:

  • Efficient localized heating: Perfect for heating a single room or a specific area.
  • Cost-effective for short-term use: They are cheap to buy and inexpensive to use for a short amount of time.
  • Convenient: Space heaters can be easily moved from room to room and they don’t need any installation.

However, their drawbacks include:

  • Potential safety risks: If not used properly, they pose a fire hazard.
  • Higher electricity bills: Can be expensive to run continuously.
  • Not suitable for large spaces: Ineffective as the sole heat source for entire homes.

Central heating vs Space heater

Central Heating Systems: Advantages and Disadvantages

Central heating systems, on the other hand, present a unified solution for warming an entire building. Their consistent temperature control creates a uniformly comfortable environment. These systems are also safer as they lack the exposed heating elements of space heaters. Nevertheless, they entail higher installation costs and may lead to energy wastage if heating unoccupied rooms.

Advantages of Central Heating

  • Uniform Heating: Consistent warmth throughout.
  • Safety: Reduced risk of fire hazards.
  • Long-Term Cost Efficiency: Potentially lower utility costs.

Disadvantages of Central Heating

  • Higher Installation Cost: Significant initial investment.
  • Inflexibility: Heats the entire space, not specific areas.
  • Potential Energy Waste: Heating unused rooms.

Energy Efficiency of Space Heaters vs Central Heating

When considering energy efficiency, the verdict isn’t black and white. Space heaters, being less efficient in large areas, are ideal for heating small, confined spaces. Conversely, central heating systems are more efficient in uniformly heating entire buildings. The choice hinges on your specific heating needs and the size of the area to be warmed. While thinking about central heating vs space heater it is essential to take into consideration the following information. Space heaters — smaller spaces, central heating — larger ones. Don’t forget that with any heating and cooling assets Fuse Service is your contractor to make your home warm and cosy.

Cost Analysis: Space Heater vs Central Heat

While choosing a heating system, considering the cost is also important. Central heating systems, even if more costly upfront, can be more energy-efficient in the long run, particularly for larger homes. They distribute heat evenly and maintain a consistent temperature, reducing the overall energy expenditure.

Space Heaters:

  • Initial cost: Low
  • Operational cost: High (especially when used extensively)
  • Best for: Small spaces or supplemental heating

Central Heating:

  • Initial cost: High (installation and system)
  • Operational cost: More efficient in the long run
  • Best for: Whole-house heating and larger areas

Suitability for Different Spaces

The choice between using a space heaters vs central heat also depends on the size and layout of the home. Space heaters are ideal for small apartments, individual rooms, or as a supplemental heat source in larger homes. They are also a good choice for homes in milder climates where central heating might not be necessary.

These systems also offer the benefit of improving home value and appeal, an important consideration for homeowners.


In conclusion, the choice between space heaters vs central heat always depends on individual needs and circumstances. If you live in a smaller space or need heating for just selected rooms, a space heater is your hero.

We chose Fuse to do the HVAC portion of our home remodel and we're very happy with their work! They installed a full Mitsubishi Mini-split heat pump system all throughout our house in 6 rooms. It was a massive job and they did the work relatively quickly and efficiently. The supervisor, Maxim, was very friendly and knowledgeable. Out of several bids that we got, theirs was the only one that gave us everything we wanted at a competitive cost. We'd be happy to recommend Fuse! We also had Fuse Electric work on the electrical portion of our home remodel, for which I wrote up a separate review.

We got our duct work completely replaced in our 50 yr old home. They recommended the work, other companies didn't do this much due diligence and mentioned about asbestos but FUSE technicians went step ahead and climbed into attic and our crawl space to ensure there were no asbestos to begin with. Honest people and very competitive if not best quote I got. Moreover the installer, David and Jeremy worked 2 long days non stop to get work done at our home with 100% satisfaction. David explained everything to me and provided other recommendations for future. He is the most honest technician I have encountered in so long. Because of David I wouldn't hesitate to work with FUSE again. Thank you for such a great work. Very happy and highly recommend FUSE!!

The technical crews were excellent; very knowledgeable and capable. They were able to do our HVAC, water heater and ductwork replacement even when faced with several unexpected and very challenging situations. David in particular worked some very long hours to get everything installed correctly. The administration side had a few glitches, but everything worked out OK. I would recommend them, but if you are eligible for the Penninsula Clean Energy interest free loan, be sure to apply for it before the work is completed.

Exceptional service from FUSE HVAC! They installed a Mitsubishi HVAC system in our home, and we couldn't be happier. The team was professional, knowledgeable, and efficient throughout the process. Our home is now perfectly comfortable year-round, thanks to their expertise. From consultation to installation, everything was seamless and hassle-free. Highly recommend FUSE HVAC for anyone looking for top-notch HVAC solutions!

Fuse HVAC installed Mitsubishi Heat pump in my house and completed the project on 31st March 2024. David and Jeremy started the project and David finished the installation. David worked Saturday and Sunday until 11 PM to complete the work. It took 4 1/2 days. I am very happy with the work that David performed. I was watching the process of installation of the pump and was very satisfied to see that after finishing each step David will spend 10-15 min inspecting the work that he did to make sure that there was no mistake. The result was that during pressure testing to check for gas leakage or when the heat pump was run there was no unanticipated issue. The new ductwork that was installed by FUSE passed the HERS test. FUSE is also installing the attic fan to keep the air circulation going and keep the attic cooler. FUSE was referred to by my friend who used them for installing a similar heat pump and although they were a little more expensive than a few quotes I got from other vendors, I decided to go with them based on my friend's recommendation. I had made a right choice! My only criticism for FUSE is they are not able to estimate the time that it will take to finish the project. They told me it will be done in 3 days but it took 4 1/2 days. My project needed the air handler to be moved to the attic but because the space which had the gas heater was too narrow for the air handler. On the whole it was a good experience working with FUSE. They kept us warm for two days with heater fans and David worked Easter Sunday until 11 PM to install and start up the system without hurrying up at any step to get the installation completed earlier. A big thanks to him and to his assistant Jeremy!
