There are a few simple signs to look out for to tell if your house is losing heat.
Firstly, if you notice drafts in close proximity to windows and doors, it is likely that warm air is escaping the house and being replaced by cooler air.
Also, significant visual spaces surrounding fixtures and outlets can harness heat loss. Such sizeable gaps offer a easy entryway for outside air.
And on the outside of the home, a lack of frost appearing on your roof can actually indicate heat loss if surrounding properties are frosty.
