Glass is tempered by passing it through a furnace then blasting it with cool air, usually on a bed of rollers. If you dont see a bug, look for the ripples from where the hot glass sagged between the rollers.
1946 Colonial with a c1980 addition. This is a 3' electric baseboard heater stuffed between a shower and a toilet. This can't be kosher, can it? Click to Enlarge 12.34 KB
My mother has an antique magneto blasting detonator...the wooden box with a tee handle favored by cartoon characters. As teens my brothers and I would take turns holding the terminals while one of us operated the handle. I'm amazed we all survived.
Pay for one full set of good locks, plus a few extra. Have everything master keyed and rotate them. Yale commercial stuff should last 7-10 years, depending on use/abuse and turn over.
The Schlages are bad. So bad that several of the bigger wholesalers dropped them. Schlage cylinders have gotten pretty cheesy in general. I had one explode on a reversible lever when I popped it to switch handing. $100 lock set was scrap before I got installed.
The EPA doesn't have time for that, they are too busy inventing science for their next decade long development of overreaching regulation and burdensome pointless protocols.
There is a two day CE seminar sponsored by a local inspector cum inspection school/report system company and the local ASHI chapter coming up in October. I have been to two of them and the content has been consistently bad. Still, I think I'm gonna go for the entertainment value. This year there are presentations by Joe Ferry esq and P Nathan Thornberry. It sounds like a hoot.
An uninsulated tank would reach 60 most of the time just sitting at n my basement. No fuel needed. Marc, the second tank experiences greater temp swings. It runs more frequently and for longer periods than the preheated. As a result it also sees more condensation. I've been in my house less than 15 years and have installed 3 water heaters there. The last thing I need to do is hasten the detritus.
