Energy Efficiency

Reducing the amount of energy used in our homes and workplaces has become a big issue in recent years. Carbon dioxide emissions are rising and causing irreversible damage to the global climate. Maximising your energy efficiency can not only sooth your conscience but it can also improve your bank balance as you spend less on wasted energy.

The government have released a number of energy saving schemes, including a Code for Sustainable Homes, which was introduced in 2007. The Code lays the foundations for future greener housing. All new homes are now required to have a Code rating and certificate in their Home Information Pack. This ensures that all energy using devices in the home will be energy efficient and cost effective. Energy efficiency is also being encouraged in existing homes and there are a number of things you can do to improve this.

For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Update your boiler to ensure that it is running safely and efficiently. To control the use of energy, you should consider on-site generation of renewable energy through solar power, wind power or hydro power; though these are the most expensive features you can add to a building.

There are various motivations to improve energy efficiency. Reducing energy use will reduce energy costs and may result in a financial cost saving to consumers. Investing in energy efficient technology will pay off in the long run as energy costs are off-set. You may even end up putting electricity back into the national grid and earning a percent of profits.

Greenhouse gas emissions need to be controlled if climate change and global warming are going to be halted. The International Energy Agency says that improving energy efficiency in your homes and at work could reduce global energy consumption by a third in the next forty years.

Efficient Heating Air conditioning is the removal of heat from indoor air for the thermal comfort of inhabitants. Energy Efficient Heaters can be used for many types of transportation, including cars, trains, ships, aeroplanes, and other vehicles.

Domestic Air Conditioning

Need to dehumidify and extract heat from your home? The solution is to invest in an air conditioning system or full HVAC system. Air-con provides comfort in both hot and cold weather by regulating internal temperatures.

A typical domestic air conditioning system consists of wall mounted units in each room with a small compressor unit which is mounted externally. The two components are linked with a pair of thin copper pipes which allow the flow and return of refrigerant gas. A fan unit and the external compressor will be driven by a 240 volt electric supply. A remote control is then typically used to turn the system on and off and change the temperature and fan speeds.

The required temperature can easily be reached and maintained with the introduction of inverter technology. This has also vastly improved the efficiency of modern air conditioning systems.

Whilst most people holidaying on the continent have heard air conditioning units constantly battering noisily away this is no longer the case with modern units. Current units are so quiet that in a residential neighbourhood it is unlikely that noise would be an issue whatsoever, providing that the unit manufacturer and siting were given careful consideration.

Domestic air conditioning is really worth the investment. As summer temperatures increase over the next 10 years it is expected that most British households will install some form of air conditioning. It’s also a great energy efficient alternative to central heating as warm air can be blown out instead. This is done by simply running your system in reverse. It is also less expensive to install – coming in at around 2000 to both purchase and install a domestic air conditioning system.

Hot Water Radiators

The range of gas boilers available is currently vast but recent changes to the Building Regulations has meant that recently all boilers are required to be high efficiency boilers or Condensing Boilers. Condensing boilers basically employ a design so that more heat is recovered from the gas energy that is inputted into the heating system.

Radiators take several different forms from a baseboard-type radiator to an upright decorative design. The most common problem in hot-water systems is unwanted air in the system, which can cause unwanted banging or creaking sounds. To combat this, at the start of each heating season, while the system is running, go from radiator to radiator and open each bleed valve slightly, then close it when water starts to escape through the valve, this takes air out of the system You may need to go from radiator to radiator, back to the start and go through the process a couple of time to rid the system of all the air.

Most natural gas boilers are suitable for Propane LPG fuel options and require only a change of burner nozzle. Many boilers are now able to run in conjunction with solar panels where gas forms the secondary top up, heat source. Solar smart combi boilers are now being produced by many boiler manufacturers. Other new features available are economisers, or top box gas savers, where even more heat is recovered from flue gases by incorporation of a secondary heat exchanger.

Oil fired condensing boilers are available but due to high oil prices these tend to only be the boiler of choice where natural gas is unavailable. Oil fired boilers either have aluminium, cast iron or high molybdenum stainless steel heat exchangers.

System boilers have all the benefits of combis but tend to provide a higher output capacity. They work on a sealed system basis and are predominantly for central heating. If domestic water heating or commercial water heating is required then a storage cylinder is provided in the traditional way.

Air Source Heat Pumps

If you live in a warm climate, and when professionally installed, an air-source heat pump can provide an effective and efficient heating and cooling solution for your home. In fact, a correctly installed one can deliver between 1.5 to 3 times more heat into the home than the actual amount of electric they consume, making them highly efficient.

However, modern technology allows many inverter units to be run off a single compressor and this is an alternative method of providing air conditioning to commercial premises. Technological advances allow long refrigerant pipe runs of up to 170m and the small diameter pipes which are now used result in less volume of refrigerant gas.

Efficiency is further improved by VRF (variable refrigerant flow) techniques. The gases used within air conditioning systems are some of the most harmful to the environment hence the opportunity to reduce the volume of those gases is to be welcomed. If inverter units are used in commercial buildings, these are often ceiling cassettes which come in a variety of specifications (1, 2 and 4 way cassettes). Perimeter areas and corridor areas often use air conditioning console units.

A heat pump’s refrigeration system consists of a compressor and two coils made of copper tubing. One end of the copper tubing is indoors and the other end is situated outside of the building. Usually the copper pipe is surrounded by aluminium fins to aid in the transfer of heat.

In heating mode, liquid refrigerant in the outside coils extracts heat from the air and evaporates into a gas. The indoor coils release heat from the refrigerant as it condenses back into a liquid. A reversing valve, near the compressor, can change the direction of the refrigerant flow for cooling as well as for defrosting the outdoor coils in winter. When the outdoor temperature drops significantly, a less-efficient panel of electric resistance coils, similar to those in your toaster, kicks in to provide indoor heating. As a result, air-source heat pumps are no very efficient for heating homes in areas that are subjected to prolonged cold spells.

Energy Emissions and CO2

Making your home and office more efficient in energy usage is one of the biggest contributions that you can make to reducing carbon emissions and reducing the effects of climate change. Energy used in homes is responsible for more than a quarter of all UK carbon dioxide emissions, which is the main greenhouse gas causing climate change.

The Carbon Emissions Reduction Target (CERT) was developed in April 2008 to help achieve Government targets to reduce emissions. It is expected to run until 2011. The UK Government currently hope to reduce harmful emission by 34% by 2020 and a further 80% by 2050. To do this they are encouraging energy companies to ensure the amount of CO2 emissions from customer homes are reduced through the CERT programme.

Therefore energy and gas suppliers are promoting energy saving technologies for use in your home. Thus includes loft and wall insulation and renewable energy generators such as solar panels, biomass heaters and garden wind turbines.

Over 300 a year can be saved through conscious energy saving techniques in every home, say experts. This can be done through simply unplugging appliances from the mains when they are not being used, boiling the kettle with the right amount of water, or using energy efficient light bulbs. Not only will this reduce your energy bills but it will also allow you to rest assured that you are reducing your carbon footprint and doing your bit for the environment.

Increasing the insulation or updating your boiler arguable equates to the biggest contribution to making your home energy efficient. A new boiler can reduce the energy usage of a decade old boiler by a third.

CERT will mean that energy suppliers can provide grants to help you pay for energy efficiency measures and technologies for your home, a measure which is beneficial to both you and the environment. You should also note that you are eligible to take up grants from any energy company, regardless of whether they supply your gas and electricity.

Heating and Plumbing Accessories

Open vent boilers work in a traditional manner, whereby the heating circuit is pressurised using a high level cold water tank usually located in the loft. The open vented boilers, whilst being very traditional in the plumbing arrangement, are however usually wall-hung boilers which help to save large amounts of space.

Typically heat is recovered from the flue gases; the water vapour in the exhausts gases is cooled by the incoming air, thus causing the vapour to form into a liquid state, hence the term condensing. Condensing boilers tend to work at their highest efficiency at lower temperatures so boilers are often designed to feature fully modulating operation at low temperatures, ensuring the output matches very closely to the heat demand.

Combination boilers, usually referred to as ‘Combis’, are the most commonly found boilers in the UK. They operate in a similar way to a traditional ‘gas geezer’ whereby water is heated on demand and there is no heat storage facility. This means they are extremely compact and ideal for new house builds where space saving is often at a premium.

In recent years hybrid versions of combination boilers have evolved whereby a small amount of water storage is provided within the casing of the boiler. These are known as storage combination boilers.

Typical output capacities of combination boilers are 24kw, 28kw and 35kw but this varies with each boiler manufacturer. The efficiency of the boiler is reflected by the SEDBUK rating and ideally one should be seeking a SEDBUK, A or B rated boiler.

Traditional solid fuel boilers tend to have twin wall fluing systems due to the extremely high temperature of the flue gases.

Warming To Your Bill

Efficient heating contributes to our ever lasting fight with saving energy but it also helps in the wallet/purse department! With a combination of the right controls and the right boiler it is possible to be saving somewhere in the region of 225 a year, a handy bonus for the household over the year. Remember your boiler is the biggest carbon emission producer in your gas heated home contributing to almost 60%.

How long have you had your boiler? The current lifespan of a boiler is around 12 years, replacing your existing boiler with a more up to date energy efficient condensing boiler can make a huge difference.

What does an energy efficient condensing boiler do? To put it simply it provides more efficient heating for your home.

Controlling your boiler A normal 9 to 5 worker may set their heat to come on in the morning and go off when they leave the house and then may set it for when the first person arrives back in the house. This is just an outline and obviously it is important to taper your heating controls to working hours, duties and hobbies. It is important to be conscious of efficient heating within a home as carelessly leaving your boiler on during the day may prove disastrous to your bill.

Timing is not the only thing you can do to help with improving heating, turning your heating down by just 1C can make a saving of around 55.

To get the most efficient heating for your home involves more than just the length of time the heating is being used. The temperature of the boiler is equally important to savings. By turning down your thermostat down just 1C could save as much as 55.00 per year.

What will the future hold? The future is already upon us, an application available on the iPhone allows you to control the latest boilers within your home from wherever you are in the world. So you can even keep an eye on the children turning the heating up to ridiculous temperatures.

The iPhone has now developed an application that can control heating from wherever you are in the world. This will definitely improve efficient heating and limit wasted energy.
