If your house is always cold, start by finding where heat is escaping and whether the heating system is distributing enough warmth. Check for drafts, cold windows and uneven room temperatures; seal suitable gaps without blocking required ventilation. If the whole home stays cold or the cause is unclear, arrange a qualified assessment of the building envelope and heating system before investing in major work.
First work out whether the problem is one room or the whole house
Notice where and when the cold occurs. A single cold room points you toward local drafts, windows, airflow or heat delivery. If every room is cold, consider broader heat loss through the roof, walls or floors, significant air leakage, or a heating system that is not working effectively or suited to the home. This is a practical way to narrow the checks, not a diagnosis by itself.
- Check whether doors, room controls or airflow patterns might be affecting how heat reaches the cold room.
- Note whether the problem changes on windy days, at night or when the heating is running.
- Look for visible gaps and feel for moving air around doors, windows, floorboards, skirting, vents and fireplaces.
Find and seal drafts without blocking ventilation
Air leaks can occur in obvious places such as doors and windows, but also around utility penetrations, chimneys, recessed lights and unfinished spaces. The U.S. Department of Energy recommends finding and sealing the largest leaks first in its Home Energy Checklist. Breezes, moving curtains, or whistling and rattling in windy weather can help identify trouble spots.
For a suitable gap, options include weather strips, foam strips, a door draft stopper or appropriate sealant. Choose a material that fits the gap rather than forcing an ill-fitting seal into place. Australian government guidance cites a CSIRO 2015 estimate that sealing gaps may reduce heat loss by 15% to 25%; that is a potential estimate, not a guaranteed result for an individual home. See Insulation and draught proofing.

It also features handy extras for a hassle-free experience (remote control, 12-hour timer, mute, child lock, and memory function).
Do not seal vents indiscriminately. Unflued and open-flue gas heaters need adequate ventilation. Australian guidance notes that unflued gas heaters emit carbon monoxide, nitrogen dioxide and water vapor during combustion, and that restrictions vary by jurisdiction. Check the requirements for your appliance and location in the Australian Government’s heating and cooling guidance.
Reduce heat loss at cold windows
If windows feel cold or the room loses comfort near them, thick curtains or other suitable window coverings can help. Open curtains when useful winter sunlight is available, then close them at night, as the U.S. Department of Energy recommends in its Home Energy Checklist. Coverings can improve comfort, but they do not replace fixing a major leak or addressing inadequate insulation.

- 2 in 1 heater fan: This ceramic heater offers dual heating modes (1500W/750W) plus a cool air fan, making it ideal for both winter and summer. With automatic thermostat control, it cycles on and off to maintain your preset temperature without any manual adjustment. A practical and thoughtful gift for working from home, or for family, friends, and colleagues during the cold season.
- Multi-protection safety system: These heaters are made of V0 flame retardant material avoiding any fire hazard. Automatic safety shut-off system will shut the heater off when the heater overheat. The tip-over protection system will automatically shuts off with a loud beep if knocked over by accident and it will come back on automatically if it is up righted.
- Portable and Powerful: The mini heater with build in carry handle helps to reinforce the potential of rather low electrical bills by using at the place where you need when you don't want to warm the full house with other centralized heaters.
- Quiet and fast heating: The ceramic space heater is impressively quieter than most conversation levels, which is quiet enough for most people to use in a bedroom while sleeping or working. With PTC heating tech and high speed fan, it is rated to heat up to 200 square feet in seconds, which would cover most bedrooms, offices, bathrooms and smaller living rooms.
- Upgrade abs material: Upgrade abs material applied, which is more flame resident. The room heater with six feet lead cord and 2 prong connection has a long lasting life. The space heater for indoor use makes a noticeable difference and works well in small to medium rooms when positioned properly.
Assess insulation before taking on major work
Heat can escape through the roof, walls and floor. Australian government guidance says appropriate insulation in these areas can potentially save over 50% on heating and cooling costs, depending on the home and climate; it is not a typical or guaranteed saving for every household. The same guidance reports that heating and cooling account for 20% to 50% of energy used in Australian homes, depending on climate zone. These figures apply to Australian homes, not homes everywhere. See Insulation and draught proofing and Heating and cooling.
The right insulation type and amount depend on local climate, construction and how the home is heated. Larger insulation jobs merit qualified advice and careful installation. Australian guidance also advises having an electrician check wiring before it is covered by insulation. Avoid treating insulation as a generic add-on: the assessment should identify where heat is being lost and what is appropriate for the particular building.

Use an energy assessment when the cause is unclear
If drafts are hard to locate, several rooms are cold, or the heating system and building shell may both be contributing, arrange a professional energy audit or qualified inspection. A blower-door test can help reveal air leakage. The U.S. Department of Energy describes whole-house weatherization as assessing the home’s shell and mechanical systems together, rather than treating one measure in isolation. Details and availability vary by location; see Whole-House Weatherization.
Check the heating system before replacing it
If the equipment is malfunctioning, aging or unable to meet the home’s needs, have it inspected by a qualified professional. A system upgrade may make sense in some homes, but should be considered alongside air sealing and insulation so the new equipment is sized and selected for the building and climate.

Heat pumps transfer heat rather than generate it in the same way as electric resistance heating. The U.S. Department of Energy says a heat pump can use up to 75% less electricity for heating than electric resistance heating; that comparison is not a guaranteed reduction in a particular home’s bill. Modern air-source heat pumps are an option in colder regions. If outdoor temperatures regularly fall below freezing, DOE advises considering the ENERGY STAR Cold Climate label. Read its Heat Pump Systems guidance.

Temperature advice depends on location and household circumstances. UK government guidance suggests trying to heat frequently used rooms to at least 18°C. Australian home guidance gives 18–20°C as a winter thermostat range.
