Electricity Saving Devices

We’re always on the lookout for ways that can help you save on your electricity bill and, as well as advice on the latest lighting technologies such as LED lights, we can install devices such as immerSUN to help you get more out of your Solar PV system and Vphase, a voltage optimisation technology.

Alternative Lighting

Want to save on your electricity bill? The Energy Saving Trust reports that lighting accounts for a whopping 18% of a typical household’s electricity bill. Give us a call and we can help you to cut your expenditure by taking advantage of the latest energy-efficient light bulbs and technologies.

Some of the energy efficient alternatives to traditional incandescent light bulbs are listed below. The Energy Saving Trust reports that if the average household replaced their remaining old-fashioned bulbs with CFLs, and their halogens with LEDs, it would cost about £100 and save about £35 a year on bills.

Compact Fluorescent Light (CFL) bulbs

CFL bulbs work differently to traditional incandescent bulbs. Instead of producing light by heating a metal filament until it glows white hot they contain argon and mercury vapour which is excited by a current to produce invisible UV light that in turn excites a fluorescent coating on the inside of the bulb.

CFL bulbs are more efficient than incandescent and halogen bulbs and last longer. However they can take a while to warm-up and people can find the light they emit less attractive than that emitted by incandescent and halogen bulbs. They must also be handled and disposed of carefully.

Halogen bulbs

Halogen bulbs work in basically the same way as incandescent bulbs albeit they contain a gas from the halogen family. They are only slightly more efficient than incandescent bulbs however they produce the same bright, crisp light and do not take the time to warm-up that is often associated with CFL bulbs.

LED bulbs

LEDs or Light Emitting Diodes are a special form of diode – an electronic component – that is designed to give off light. They are very efficient and long lasting, do not suffer the delayed warm-up that can be a feature of CFL bulbs and emit an attractive light. The downside is that can be relatively expensive however prices are now falling and they are becoming increasing attractive.

immerSUN

An immerSUN box helps you to get more out of your Solar PV system by helping you to use more of the electricity it produces and reduce the amount you buy in from a third party supplier.

It works by monitoring your Solar PV system and diverting electricity that otherwise would be exported to the grid to your immersion heater to generate hot water. The only requirement is an immersion heater with a dedicated circuit to the same Consumer Unit as your Solar PV system.

Excess electricity can also be diverted to alternative heating devices.
