How often should a house be rewired?

A house should be rewired when it becomes appropriate. - Homeowners should consider a rewire if they are undergoing extensive work as this will mean walls, ceilings and floors will likely be renovated anyway; allowing cable to be run and saving the intrusive work being done after decoration is complete. - Old wiring can be an issue with new fittings. Things such as unearthed circuits, unbonded water and gas mains, rubber cable and aluminium cored cable. Will all be considered as reasons for a rewire, some may be dangerous so an EICR (electrical Installation condition report) is used to determine the current state of wiring. - It may be the case that the wiring is adequate and no measures need to be taken immediately or that a fuse board (distribution board) upgrade will suffice to ensure the house is electrically sound.

How does an electric boiler work?

It’s essentially a large kettle. A length of coated and very durable conductor (similar to MI cable) is immersed into the water of the tank; when energised it creates an ambient heating of the water in the cylinder (water tank). The inner conductor is turned on and off by thermostat which can be controlled differently to make it most efficient for the installation. The hot water created by this is piped out to the house. A water cylinder has an input (cold) and an output (hot) attached. The hot may be found coming out of the very top of the cylinder.
