I purchased a 25 year old house about three month ago (boiler + BB heaters) and my heating costs are through the roof! I have asked around and most people with the same SQF as mine are paying about 50% less than what I'm paying so there's something definitely wrong here.
The house is a bungalow with an unvented/ unheated crawl space, about 2700 sqf and concrete walls and floor in the crawl space. There are no insulations in the walls and the floor and only minimum insulation around pipes and such in the CS ceiling. I have limited money so I need to pick and choose carefully what to do to bring my heating costs down. I have taken the most logical steps (prevent drafts, instal programmable thermostats, reduce the temperature by 2 degrees and shutdown the zones not in use at night/ while at work during the day with almost no effect.
My options are:
- Replace the furnace (a 20 years old one which works fine).
- Insulate the crawl space
- declare bankruptcy and freeze to death!
So here are my questions:
- Can insulating the CS ceiling make a huge impact? If yes what should I do, ceiling or walls and floor as well?
- Can replacing the boiler make a huge impact?
I have money to do only one of these and not both. Thanks in advance for all the help!
