Energy-Efficiency Upgrades to a Knob-and-Tube-Wired Home
Daly City is the location to be exact. I pretty much feel like I spent a fortune buying a really crappy house (as far as building science goes)
The heating bill is astronomical. I went from an apartment building paying about $50 for all utilities a month, to about $500 per month on just electricity/gas in the winter months in this new house. What are the big bang for the bucks upgrades I should do?
There’s no insulation in the house. It’s using knob and tube wiring everywhere, so I’ve been hesitant to add insulation. However most contractors I’ve spoke to said knob and tube should be removed, and its safer, but for the price, and hassle, it’s better to just risk putting insulation over it, since it’s relatively safe, and most likely won’t have any issues.
Most big appliances are gas, like the furnace (80% efficiency 60k BTU), stove, laundry dryer. I recently replaced my water heater to a hybrid heat pump water heater since it had to be replaced anyway and there’s a rebate in my area currently. Not sure if I made the right decision because I realize electricity is one of the highest in the nation here in this area.
Windows are mostly double pane windows, not sure what brand. But it’s probably not a super high end brand. There’s a few windows that are still those aluminum frame, single pane, but just a few.
Crawl space is also vented, not sealed/encapsulated, but not sure if it warrants sealing in my area’s climate.
I may be considering solar panels in the near future.
Any advice would be appreciated! Thanks
