Empty rooms are always colder It may seem a bit odd, but it's a simple climatic principle. Air heats and cools faster than objects, but it doesn't retain the temperature. Furniture, curtains, clothes, and decorations absorb heat and then re-radiate it into the air, making it warmer.
Whether you plan to leave for a vacation or for the season, most heating and cooling professionals recommend setting the thermostat to 55 degrees Fahrenheit. This temperature will reduce your heating costs and minimize the risk for hazards such as frozen or burst pipes and flooding.
Piles of clothing and other kinds of clutter absorb heat and keep it trapped in the room. The less clutter you have in the room, the more available space there is for the heat to disperse and the faster it will cool down. A lot of clutter can also restrict airflow, making it feel even hotter in the room.
You have insufficient insulation.
Your house and attic insulation can wear down over time. Your house also may have hidden attics that aren't properly insulated or uninsulated garage walls that are attached to your home, and this can cause problems with heat escape, unwanted airflow, and drafts.
The first is to check your vents. You might have heavy furniture or items covering up your vents, absorbing all the heat. This is a very common reason why one room in a house is always cold, and it's easily solved by simply moving the items away from your vents, allowing an unobstructed flow of warm or cool air.
Closing Doors To Unused Rooms Creates AC Inefficiency
If the intake is blocked because of a closed door, the balance is off, negatively affecting the air flow your system needs to cool your home efficiently. Your system can become damaged, resulting in AC Service.
The main areas where heat escapes are the loft, walls, windows, doors and floors. In fact, in older properties, original windows can be a dual offender with draughty timber frames and single glazing causing heat loss in your home.
That's because Australian homes are closer to tents than insulated eco-buildings. As winter sets in, and temperatures plummet, it can sometimes feel as cold inside as it does outside. The reason for this is the poor thermal performance of houses in Australia.
The reasons your house is cold even with the heat on could be because of poor insulation, your furnace not working properly, rooms with high ceilings, or your heating system doesn't cover the whole house. Each of these issues can prevent your home from properly heating.
Risk of infection
Living in a cold house can also increase the risk of respiratory infections like flu, particularly in older people and young children. Cold temperatures can dry out the mucus that helps the body fight off viruses, making it easier for infections to take hold.
Absorbs Heat And Makes For A Warmer Space In Winters – In winters, a room full of furniture will feel warmer than an empty room. It happens because the pieces of furniture and furnishings trap heat and increase the indoor temperature. Furthermore, the HVAC system is also adding to the warmth of the room.
The air can circulate easier, so it feels cooler, and there is not as much stuff to keep cooled down. Sort of like an emptier refrigerator is easier to cool than a crammed full one.
But in actual fact, fans don't cool down your room in the way that an air conditioning unit can. They do relieve some of the struggles of living in high temperatures, circulating air and making you feel cooler, but even the best modern fans won't actually lower the temperature of your room by themselves.
If your home is vacant, you need to find the right middle ground on the thermostat. If it's too cold, you increase the freeze risk. If you keep it too warm, you risk wasting money and energy. As a general rule of thumb, leave the heat on and set your thermostat between 55 and 60 degrees.
What Temperature is Too Cold for a House? While everyone has a different tolerance to cold, ideal winter heat settings should generally be at or above 63 °F (17 °C). Excessive cold (anything below 62 °F or 16 °C) in your home can actually raise your blood pressure as your blood “thickens” in the chilly temperatures.
In The Summer
Turning your thermostat up seven to 10 degrees F should help you save on your energy costs. This means you should leave you thermostat between 85°F and 88°F degrees in the summer when you are not there. If 78°F sounds too hot for you, experiment and see what temperature works best for you.
First, the thermostat might be set too low. Second, the pilot light could be out. Lastly, there might be an issue with your furnace – if this is the case, then you should call a professional to take a look at it. A final reason why your heater might not be effective is that you have a drafty home.
Check for Closed or Blocked Registers. Every furnace technician has a story about a cold room that was warmed by simply opening a register or two. Be sure to check all the vents in the room to ensure they're open. Furniture and rugs can also block airflow, so do some rearranging if needed.
Air leakage – if there are gaps and cracks in your home (under doors, around windows, through attic penetrations, around your foundation, etc.) warm air will leak into your home increasing the temperature, and potentially the humidity levels, in your home.
“Australian housing types like terraces originate from England [but] they haven't really been adapted for the climate here,” says Sam Marshall, founder of award-winning firm Architect Marshall and lecturer of the Faculty of the Built Environment at UNSW. As a result, they're both hotter in summer and cooler in winter.
Set your thermostat
Keep the internal temperature of your heating set to between 18°C and 20°C.
It is typically recommended that the bathroom should be the warmest room in a house, with a temperature in the region of 22 to 24°C. This is above the recommended ambient temperature of a home in general, which sits between 18 and 20°C.
Only approximately 1% of this heat resides in the atmosphere. The vast majority of excess heat (89%) is absorbed by the ocean. New assessments of borehole measurements show that the land heating is 6%. About 4% of excess heat causes loss (melting) of both land ice and floating ice.
In an average home, 15-25% of your heat is lost through the walls. Besides your roof, your walls make up one of the largest surface areas of an average home, therefore being largely responsible for thermal performance. This is compared to windows, which account for 10-20% of your heat loss in the cooler months.
