“How are bugs getting into my home?”
They can get in virtually anywhere because they are so small but I can tell you from experience that 2 areas are highly suspect, breaker panels and weepholes. There is a BIG hole in the back of ALL exterior breaker where wires from the breakers enter the home. This is a “super highway” for bugs. Seal it up with caulk, expanding foam or steel wool!
Your interior or garage breaker panel should be caulked all around. If yours isn’t, bugs WILL get into your home
BUGS LOVE WEEPHOLES TOO. The are found in masonry over windows and doors and at the bottom of most masonry walls. I cut up a copper “Chore Boy” (used to clean pots and pans) and stuffed it into all the weepholes around my house and there were DOZENS of them. Do NOT use steel wool, it rusts.
WHY DOES IT TAKE SO LONG FOR HOT WATER TO GET TO MY BATH/KITCHEN/LAUNDRY ?
I think you know the answer to that! Your water heater is too far away. A lot of 2 story homes have the water heater in the attic but the fixtures they supply are on the 1st floor! Most dishwashers and a LOT of washing machines on the 1st floor of 2 story homes NEVER get hot water from a water heater. (the cold water in the lines between the tank and appliance is more than enough to fill the appliance!).
I put small water heaters next to areas where it takes a long time to get hot water. By the time the small tank runs out of hot water, hot water from my main tank is at the fixture. Some plumbers install circulating pumps but most run 24/7 AND are circulating HOT water thru your water lines which are probably NOT insulated AND are running thru AIR CONDITIONED space. Think about that!
Update on my solar system (described last month): Since it went “hot” 3 weeks ago, it has provided 92.3% of my electricity (and several days it has been overcast). It cost $3800 and payback period is 4.3 yrs. If you don’t have one, you’re throwing money away!
