Yes.
That's why it's important to measure the air delivered to the room, and if it's not as expected, look for the reason. Often there is just a central return grille, or one on each level of the house, and if a room has the door closed the supply flow to that room drops as the room is pressurized by the air trying to find a path back to the return. If that is the problem, we often recommend installing some form of transfer grille. Here's one: https://www.tamtech.com/product-cate...r-grilles-rap/ Quote:

If there were a space heater that was guaranteed 100% to not be a potential fire hazard, I'd get one, but I don't think such a thing exists. As for it being OK to close vents/registers for heating (but less so for A/C), I've never heard of that before. Is that true? |

While not terribly cheap, we use a Dyson heater/chiller/air filter fan. It can run at varying degrees, works quickly and you can track usage and filter life as well as air quality from your phone.
We have the tall one and it works pretty darn well, also has a remote. https://www.dyson.com/purifiers/dyso...-overview.html |

Most modern furnaces have a multi-speed fan with at least 3 speeds, so they use the higher speeds for A/C. I've got a top of the line Carrier with more speeds. It runs at a low speed for heating, but will ramp up the speed if the temperature is not increasing fast enough. Same for cooling, if the temperature is not decreasing fast enough, a higher speed is used. Most of the fans in home furnaces have forward curved blades that are only good for low pressures. I can't see why closing off vents while cooling would cause any more problems, just because the fan is running at a higher speed. Fans and pumps follow affinity laws that govern the pressure and flow, relative to fan speed. Flow increases proportionally to the motor speed, pressure increases to the square of the speed and horsepower required increases to the cube of the speed. |

They are pretty effective, and quiet enough for a bedroom, since there are no fans. Also safe--we've had years of service with no problems. I see they are sized now, and some come with remotes: https://www.amazon.com/DeLonghi-TRD4...s%2C128&sr=8-5 |

My wife and I use an electric space heater on cold winter nights. There are no registers in the upstairs for forced hot air, but I insulated the crap out of the upstairs when I built it up. No issues with overheating or any potential fire hazards and it is just a cheaper model from Lowes.

Have you considered an electric blanket for her bed? My daughter's room is (a) over our unheated garage and (b) heated by the longest duct from our furnace. Even with a booster fan in the duct, her room is always the coolest in our house. We bought her an electric blanket and she's been comfortably warm ever since.

Also, I understand today's space heaters are pretty safe, have built-in safety features, etc. Still... if there's a 0.1% chance of a fire, that's a risk that's not worth taking IMO. And I'm not sure if I have a single- or multi-stage furnace. I should figure that out. Last edited by xeladragon; 10-10-2019 at 02:55 PM. |

And I was just looking at the Dyson Hot+Cool online. Awfully expensive but... it's an option! |

So I was at Costco the other day and they had a $100 instant rebate on the Dyson Hot+Cool heater thing that Dave B mentioned above. So I bought it. It has a night-time mode, so must be safe for running at night, right? Plus it doesn't get hot, won some Parent Tested Parent Approved (PTPA) award, etc. So far, so good. Definitely not the cheapest option, but not having to worry about my daughter being cold at night is worth the investment.
