oil

An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.
The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents.

    Struggling to dismantle top fixing toilet seat

    I’m trying to replace a top fixing toilet seat but can’t figure how to dismantle the existing one. There’s no brand name found anywhere including for the main toilet. Photo attached.

I thought when I fitted the filter supplied with the tank that it was a poor design of...

    Having problems with Remeha Combi-Boiler

    For a couple of months now the CH side of the boiler has been leaking water. It would leak for a couple of days and stop. Very intermittent, but very annoying when we get water dripping everywhere (so the system would depressure quite significantly). I have isolated the behaviour to a valve on...

    Will a combi boiler be adequate for my house?

    We recently moved into a new home that currently has a Super Hot MG-100 Hydronic Boiler (installed in 1986, when the house was built). Clearly, the boiler is way past its life expectancy and in need of replacement. We had a couple of boiler companies come give us a quote and one of them...
