Is it true that number 2 heating oil and diesel fuel are substantially the same product?

If not, does diesel differ in ways that would harm a typical residential oil-fired boiler?

I'm just...

This sounds pretty half-assed, but years ago, I remember seeing someone use a two-prong to three-prong adapter with the little metal ground tab wired to a clamp on a nearby radiator.

I think this...

Interesting, but I'm a little bit confused.

Both of these pictures show three wires inside the armor cable. Are these two variations on post-1950s armor cable -- one with a bonding wire and one...

Most of the outlets in my 1920s era house are still wired with the original system of two wires in a flexible metal conduit terminating in a metal box. The outlets have two slots to accept a...

Here are some pics of our pedestal sink. I just replaced the old pvc s-trap and braided supply lines that were inside the moldy old vanity with chrome.

As you can see, the stubs through the floor...

Thanks for the information.

Very interesting thoughts.

As I understand it, the water that sits in the low bend of the s-trap acts as a plug, preventing sewer gas from rising up your vent stack and into your bathroom by way of the sink drain pipe.

The...

The frost depth here is 48" inches below grade.

The framed floor sits about 2'-6' above grade, so when I stand in the basement, there's about 1'-8" of concrete above grade and another 10" or so...

Ok, I re-checked the grounding situation, and the only wire that looks like the ground is a a single, bare copper, twisted wire, about 1/4" in diameter that leaves the bottom of the panel and clamps...

Don't be discouraged!

I installed a pedestal sink in nearly the same situation as yours several months ago, and I'm very happy with the result. My house was built in the late 1920s and, like...

If you have a low-sloped roof, you might take a look at one of the modular green roof systems like GreenGrid.

They basically assemble 2x4 ft shallow planters that...

This is probably a pretty basic question, but I'm not proud.

My old house built in the 1920s has an updated 200 amp breaker panel. Some circuits are still wired with the original flexible metallic...

Based on the discussions I've seen here and on other forums, I just re-plumbed my domestic hot water system so the outlet of the hot water coil in my oil-fired boiler connects to the inlet of the...

A basic question.

If I insulate the hot water heating pipes that run from my boiler in the basement to radiators on the floor above, I'll reduce the amount of heat lost from the pipes to the cold...
