is 50,000 btus enough for small apt?
I have a tenant w/a 50,000 btu, 4-year old thermostat (Cozy) They complain the 2-bedroom, 700-sq foot apt is not warm enough here in L.A.near the beach.
There could be other issues, (single-pane windows, high ceilings, no attic, 50s-era zero insulation, etc.)
Is there a warmer thermostat option on the market? Or should I weatherstrip the windows and doors and/or replace them with fiberglass....and forget about the thermostat?
Any suggestions appreciated.... thanks
