Stop Heat Loss & Fix the Hidden Leaks
13. Add an Electric “Fireplace” for Heat + Vibes
If the room feels cold and depressing:
- A wall-mounted electric fireplace can:
- Heat up to ~400 sq ft
- Give you adjustable flames, colors, and “embers”
- Mount nearly flush on the wall so it doesn’t eat floor space
It’s more efficient than running a real open fireplace, which often sucks warm air out of the house.
14. Insulate & Seal HVAC Ducts
If the cold room is far from the furnace, heat might be lost in the ductwork:
- Inspect visible ducts in basements, crawlspaces, or attics.
- Seal joints and gaps with mastic or foil tape (not standard duct tape).
- Wrap long runs with duct insulation sleeves or batts.
Less heat lost in transit = more heat arriving where you need it.
15. Use a Draft Stopper at Doors & Windows
Even a tiny gap under a door can bleed warm air:
- Use a draft snake / door draft stopper at:
- Bedroom doors
- Exterior doors
- Super-leaky window sills
Cheap, fast, and surprisingly effective for rooms that back onto unheated hallways or garages.
16. Seal Gaps, Cracks & Penetrations
Sometimes the cold room problem is basically Swiss-cheese walls:
- Look for gaps around:
- Pipes and wires entering from outside
- Cable/internet penetrations
- Baseboards on exterior walls
- Seal with:
- Expanding foam for larger gaps
- Caulk for small cracks
- Don’t forget outlets on exterior walls – foam gaskets behind switch plates are cheap and help stop drafts.
