Excel Electrical specialise in helping homeowners and commercial businesses to improve all aspects of their buildings’ energy efficiency. Whether you are looking to improve the energy efficiency of your lighting or heating, Excel Electrical Services Ltd can help.
Improving electrical energy efficiency reduces utility bills for homeowners and operational costs for businesses. It curbs carbon emissions, and aides in climate change mitigation. Excel Electrical Services Ltd have completed a wide range of projects helping local homeowners and businesses to improve their energy efficiency.
Incandescent, or standard bulbs are highly inefficient. Around 10% of the electrical energy converts to light. This means 90% is wasted as heat.
Halogen bulbs are similar but instead have a small pocket of halogen gas that reacts with tungsten to produce light. These bulbs burn brighter. They also use less electricity and last twice as long as a standard bulb.
Energy efficient light bulbs use significantly less energy than incandescent bulbs, and also last longer.
LEDs themselves have been around for some time, but only recently have improvements in efficiency, cost and output made them viable for the larger-scale lighting used in households, businesses and other environments. Due to rapid progress in LED technologies, products exist with wide ranges of efficiencies and life spans.
The bulbs can work for up to 50000hours, if not run outside of the specified temperature range. They use about 8-11 watts of power to replace 60 watt incandescent or 6 watts for a 50 watt halogen lamp. This capacity provides an efficiency gain of up to 80%.
Technology is available to optimise the voltage on your electrical installation.
If you can reduce and manage the voltage coming into your home. A device like this, will ensure many of your electrical appliances will be more efficient. This means they will use less electricity and cost less to run.
Voltage coming into your home is typically 245v. The ‘add-on’ device reduces this voltage and maintains 220v. Typically, whole house savings are in the region of 10%, which means, household electricity bills will be around 10% less each year.
Any ‘add-on’ device installed alongside your fuse box must be installed by a qualified electrician.
Modern well insulated homes with central heating suffer air pollution up to ten times worse than outside. Many need upgrades to provide much needed eco solutions.
Current Building Regulations Require extractor fans in all wet areas in the property. This includes key areas like the kitchen, bathroom, utility rooms, ensuites and the WC. All windows need to have trickle vents, that allow air back into the property.
The heat recovery system is designed to change the air within the property. This will happen at least once every two hours. This process continually replaces the stale damp air with fresh, warmed, clean, and filtered air.
A typical heat recovery ventilation unit recovers 60-70% of the heat normally lost through trickle vents and other breakout points in the building structure.
Ducting connects the stale air exhaust grille to the heat recovery unit and extracts via ducting to all the wet areas of the property. Stale air is able to pass through the cross-flow heat exchanger and around 65-70% of the heat is recovered.
Fresh air is brought into the property via a separate external grille. It passes though the heat exchanger and picks up the heat recovered from the stale air. There is no mixing of airflows, only the transfer of heat. The warmed fresh air is then ducted to all the habitable rooms within the property.
