First off, if you've been thinking about installing a new water heater, now might be the perfect time. According to Realm, this change has a 347% ROI. "When it comes to water heaters, you have two options: tank or tankless," Realm founder Liz Young tells Hunker. "Water heaters with tanks will save you money upfront, at about one-third the cost. But a tankless water heater lasts for two times as long and will save you money each month on your energy bill."

Another way to increase your home's value is by installing new flooring, which offers a 342% ROI. "If you're optimizing for return on investment, Realm recommends hardwood floors," Young says. "It's 50% less expensive than tile, lasts a lifetime, and is also the most common flooring in recently sold homes." And if your home's current floors are always ice-cold during the winter, even better — now you can finally get well-insulated flooring that will keep you warm indoors.

Last, but certainly not least, another winter project you'll want to consider is installing a new HVAC system. This offers a 214% ROI. "Not only do HVAC systems provide a bump in the value of your home, but they're one of the longest lasting appliances in your home. In fact, depending on your system, it may last up to 25 years," Young explains. So while installing a new HVAC system is a bit of an undertaking, it will definitely pay off in the long run.

Between these three projects, there is plenty for us to do this winter as we aim to keep warm and plan for future home profits.
