Save Money With Energy Efficient Curtains and Blinds

Up to 80% of heat loss in a property can be through windows and doors. Thermally efficient curtains and blinds can have a huge effect on energy efficiency and temperature levels within your home. You could fit replacement windows or double glazing. However you have to decide what you can afford and what the cost benefit will be.

Thermally efficient curtains and blinds can add 10 – 15% to the cost of your curtains. However these will improve energy efficiency by up to 40%

Thermally efficient curtains contain the following layers

medium to heavy weight interlining.

Cotton/ wool material sandwiched between the front (face) fabric of your curtains and the lining fabric.

Thermal or blackout lining fabric

Thermal lining fabric has a thin, rubberised backing to reduce heat loss.

Blackout lining has an extra acrylic layer to prevent light passing through the fabric.

English Heritage found that heavy curtains reduced the heat loss by 41% (and lowered the u-value from 4.3 to 2.5). Secondary glazing to existing sash windows can cut u-values to 1.7

The following give details of cost savings upgrading from single to double glazing.

Home Utility Usage Explained.

We will look through your last two years utility bills [gas/oil, electricity & water] to check how much energy your property uses and see what can be done to cut your bills. We will compare what was spent in summer and winter to identify trends and see what opportunities there are to save you money.

We will compare your costs against an average for your house size, type and location. This will give an indication of how your home compares to the average and importantly what can be done to save you money.

We aim to save you money without you changing anything you do. However once you know how much your electricity costs every time you switch on a light or boil the kettle. You may choose to change what you do and save even more.

You will be surprised at the savings that can be made by making a few changes to how you use utilities in your home. We have an extensive range of inexpensive equipment that can save you much more than you think.

We want to end fuel poverty for everyone. We cannot improve your income but we can definitely make what you have, go further.

Households are considered to be in ‘fuel poverty’ if they would have to spend more than 10% of their household income on fuel to keep their home in a ‘satisfactory’ condition. Satisfactory is defined as maintaining living areas at 21 degrees centigrade with 18 degrees centigrade in the other occupied rooms.

Gas consumption is generally governed by the size of property.

Save Energy and Money by Insulating Heating and Water Pipes

The energy-saving potential by Insulating Heating and Hot/Cold Water Pipes is often overlooked. This article briefly details the key points and financial benefits.

 

At the heart of the energy-saving Community. AIM Energy Saving You Can Trust

The heat loss from water through a pipe is dependant on four key factors, initial temperature of water at point of supply [boiler], length of pipe run to point of utilisation [tap, washing machine, dish washer etc.] pipe internal diameter [bore] and location of pipework [exposed to ambient conditions, buried in walls, through ceiling voids, under suspended timber floors].

The priority areas for application of insulation protection are pipework exposed to ambient conditions [surface mounted on walls/floors] and pipework run under suspended timber floors. These two conditions have the highest

Looking at water quality, we have all experienced tepid water from the cold tap. This is not pleasant and wasteful, if a few litres/pints are drawn off until cold water is flowing. This is wasted heat [money] put into cold water which should not be there.

An added extra benefit is the frost protection of your water pipes. We all know someone, or have sadly experienced a burst water pipe. This can be a hugely expensive and disruptive event. Insulation of water supply pipework will help avoid frost damage in cold periods. An excellent protection measure for properties that may be unoccupied during cold weather periods.

Electrical safety is also improved. BS7671 requires the avoidance of ‘mutual detrimental influence’. This is best described as sources of heat having a effect on the condition of electrical circuits.

The picture below shows how hot water through central heating pipework caused heat damage to the PVC insulation of the socket outlet circuit. PVC/PVC cables are based on 70°C operating temperature. This is the safe limit for continuous use. Electric current subject to resistance causes heat. That is what makes an incandescent lamp shine brightly and an electric toaster get hot. The critical failure can take place when the electric cable is in casual contact with central heating pipework. The temperature of the central heating pipework could be up to 80°C. Even assuming an average of 40°C, the cable was operating at 50% of designed temperature, the combined temperature would be raised in excess of the designed operating temperature of the PVC cable.

Heat damage to PVC/PVC cable insulation

Whilst the pipework insulation is being installed it is also an excellent opportunity to check the quality of electrical installation. Sadly some Tradespeople cut corners on tasks that will be hidden from view. The picture below shows poor quality cable connections found under a floor. The close proximity of water supply pipework shows total disregard for safety.

Poor quality cable connections

The picture below shows the insulation material covering a section of copper pipe.

Pipe insulation saves energy and money for up to 30 years

There are many benefits to insulating heating and hot/cold water supply pipes. The values listed below give details of what can be saved.

The data is courtesy of Armacell and based on Manchester UK for temperature figures.

Pipework   Type Optimal   Insulation Poor/No   insulation Potential   Saving
Distribution 6.93% 17.73% 10.8%
Hot   Water 2% 4.5% 2.5%
Heating 4.75% 17.5% 12.75%
Ratio   of Heat Demand 12% 39% 27%

To make sense of these percentages we can assume that a home consumes £1000.00 worth of gas per year for heating/hot water. From the above data it is possible to save up to £270.00 per year by insulating all pipework.

It is expected that most homes can have all distribution pipework insulated for approximately £550.00. The pipe insulation has a minimum life expectancy of 30 years. So if gas prices did NOT increase for 30 years the following savings could be expected £7650.00 after 30 years, or -£180.00 in year 1, +£90.00 in year 2 and £270.00 for every year thereafter.

Just consider that gas prices have risen by almost 75% in the last 10 years. That would equate to over 200% over 30 years. With gas prices rising at a similar rate over the next 30 years the total saving could be up to £20,000.00. An excellent rate of return on the investment of £550.00 today.

We can also factor in saving in wear on the boiler and circulating pump. If a boiler has a lifespan of 10 years, reduced use due to efficiencies could extend this to 12 years. This could reasonably save an additional £1500.00 over 30 years. Or put another way, in 40 years you would need to purchase one LESS boiler!

Home Energy Assessment

Home Energy Assessment

What we do

We work with you to check every appliance in your home. We note how much power each item uses and give you an expected cost to run each item per hour. You can then decide how best to use those items in the future.

The home energy assessment will also help you make informed choices when you need to replace or upgrade any items of equipment in your home.

Cost

Our whole home energy assessment service costs £75. We expect most homes to save up to £500 per year. IF WE CANNOT SAVE YOU MONEY, WE WILL NOT CHARGE YOU FOR OUR SERVICE.

We are a Social Enterprise and spend 50% of our profits on Community energy projects.

Your Heating System and Controls

We will check the size and type of radiators you have to make sure they are the right size for each room. If you need to replace any radiators in the future, the home energy assessment will show you what you need to heat each room efficiently.

We look at what type of radiator valves and central heating controls you have. The home energy assessment will list possible improvements you can make to get your central heating system work better, keeping you warm, and importantly saving you money.

Your Lighting

We will look at what lighting you have inside and outside your home. Our home energy assessment will list possible improvements you can make. We will detail costs and importantly how long it will take for any money spent, to be saved by reduced spending on your electricity bill.

Unlike many other Companies we don’t just want to sell you products. We want you to be able to make the best choices for your needs. We can offer and fit central heating boiler controls and radiator valves for you. But you are under no obligation to buy anything.

Your Electrical System

Our home energy assessment will look at your electrical system to make sure you have all items needed for your safety at home. The Electrical Visual Condition Report will show any items you may need. We will list anything you may need and offer free advice on what can be done to improve electrical safety in your home.

Your Water Supply

Our home energy assessment will look at your bath, shower, toilet, wash basins and sinks to check how much water you use. We will also look at your water using devices such as washing machine and dish washer to see how much water you use and offer advice on ways to save water.

Your Utility Bills

We will check how much you have spent on gas/oil, electricity and water to see if you are spending more than average. We can help you choose energy providers to make sure you are getting the best deal.

We are here for information and advice  to help save you money and make the world a better place.

How Much Does Standby Cost Per Year?

The table below is a sample range of similar electrical products, showing details of power consumption. The plugged in working column is for average consumption. The maximum column gives details of the highest consuming product in the sample range. Many consume 100% to 150% more power than average. With that increase consumption the running costs can double or more. Note as shown in column 1 equipment just plugged in, not switched off at the socket will consume power, even when NOT on standby.

This picture shows a wide range of home electronic appliances that we rely on for many aspects of modern living. Careful use can save energy and money. Wasting energy costs money, and after use you can’t get a refund. Picture courtesy of Abt Electronics.

The two tables give details of home computer system power consumption and home music system power consumption.
