Christmas parties and holiday gathers are annual features of December, but so are snow, ice and cold air. Make sure the next December party you throw is warm enough for people to take their jackets off and get in the holiday spirit.
Before you even start planning the party you should check the insulation of your home to minimize any heat loss. Do you have weatherstripping in your doors and windows? Did you insulate your power outlets and light switches to cut down on drafts?
Also, try to minimize how long the front door is open when guests arrive, otherwise making it harder for your heating system to work. The larger the gathering, the more the door will open.
Use a smart thermostat to control your heating system. With all the distractions and responsibilities demanded of a party host it’s easy to forget to adjust the heat in time for the party, or you may want to make it a little warmer indoors to account for people coming and going, then level it off as the party winds down. If you have a heating system that doesn’t use a thermostat you can dub a volunteer to be in charge of maintaining the temperature.
Encourage your guests to dress warmly. While you can simply tell them that they should dress for December, it’s a lot more fun to ask people to wear obnoxious Christmas sweaters. You can also put the food and any activities in the same room as the heating source.
Lastly, try serving hot chocolate, mulled cider or peppermint tea or any other food or drink that will warm people up on the inside. Use a slow cooker or electric kettle to keep things warm all evening.
