Energy Saved by Insulating Heating and Hot/Cold 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.

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

Insulating pipework saves money

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 £450.00. 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.

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!

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.

Please contact us to discuss your requirements or share your experiences of insulating pipework in your property.

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.

[Based on 4p per kWh using gas central heating]

House   Type	Window   area	1 Year saving	5 year saving	10 year   saving
Terrace	12.7m²	£119.62	£635.06	£1,371.27
Semi-detached	16.9m²	£159.17	£845.08	£1,824.76
Detached	23.7m²	£223.22	£1,185.11	£2,558.98

These results have been generated by the Glass and Glazing Federation Energy Saving Calculator.

The link below will enable you to check out the details for your home.

http://www.ggf.org.uk/energy-savings-calculator

This will help you decide if energy savings from installing double glazing will help you pay for the cost of installation.

We can offer advice on fitting and supply of energy efficient curtains and blinds.

Hard Water Treatment in Your Home

Water softening tablets cost about 23 pence each. That is adding 23 pence to every load in your washing machine. Sadly these treatments do not protect your iron, kettle, hot water immersion heater or central heating boiler.

We can fit a scale inhibitor to your water supply. It is a fit-and-forget addition to your home that offers total protection for 5 years. No maintenance is needed and all water using appliances are protected.

The chemical treatment of your washing machine will cost £40.25 per year, and all other appliances are not protected. We can protect your whole water system for £80.00. After two years you have your money back in savings from buying chemicals. The added benefit of protecting the other appliances must be worth £25.00 to £50.00 per year.

This would make you at least £370.00 better off after 5 years.

Water Supply and Use in Your Home

A hot water cylinder can give 30 litres per minute of hot water, if the cold main into the property is only 10 litres per minute, then you will only get 10 litres per minute out to taps.

The simplest way to measure flow rate is to time how long it takes to fill a bucket to known volume. For example, if it takes you 30 seconds to fill a 10 litre bucket, the flow rate is 20 litres per minute.

The local water pressure is set by your water supplier. Legally they only have to guarantee 1 bar pressure and 9 litres/minute flow.

Approximate hot or cold water demand, flow rate litre per second and litres per minute

Outlet	Litres per second	Litres per minute	Capacity [litres]	Cost per instance of use Based on rate of £0.002458 per litre
Basin [spray]	0.05	3	10	2.5 pence
Basin [standard tap]	0.15	9	10	2.5 pence
Toilet cistern [pre-1993]	0.10	6	25	6 pence
Dual flush cistern [short flush]	0.10	6	2.5	0.6 pence
Dual flush cistern [long flush]	0.10	6	4	1 pence
Shower [100mm rose]	0.30	18	90	22 pence
Bath [tap]	0.30	18	150	37 pence

Using the tables of charges below you can see how much your water bills should be and budget for future use based on current charges.

The following details costs for water and sewerage, extract from United Utilities list of charges

Type of premises	Water	Sewerage	Total
Single person household	£105.57	£138.62	£244.19
bungalows	£225.11	£232.93	£458.04
Semi-detached houses and bungalows	£205.87	£217.75	£423.62
Detached houses and Other household premises	£157.78	£179.81	£337.59

Careful users can make much savings by having a water meter fitted. The details listed below will let you compare both methods of payment

Water meter rates

Water		Sewerage
Standing Charge	Price per m³	Standing Charge	Fixed charge	Price per m3
£30	£1.374	£15	£64	£1.084

The average bath takes 150 litres to fill. A cubic meter of water has 1000 litres. From the prices above the average bath has 20 pence worth of water. A five-minute shower uses about 90 litres of water which costs about 12 pence.

Don’t forget to add the cost of what goes down the drain! Bath waste water costs 16 pence to get rid of and 10 pence for a shower.

Now total costs for comparison are Bath = 37 pence = £259.00 per year* 5 minute Shower high flow rate = 22 pence** = £154.00 per year* 5 minute Shower standard flow rate = 12 pence** = £84.00 per year*

* based on 2 instances per day for 350 days per year

**Note the shower flow rate is based on at best 18 litres per minute. Many use about 10 litres per minute. This reduces the shower costs to 12 pence [7 pence for water and 6 pence for waste water to sewer]

Save Gas by Boiler Optimising and Servicing

We will match your boiler output to the size of your home. Many boilers use more gas to heat your home than is actually needed. Following boiler manufacturers guidance, we will match boiler output to your house size. Making your boiler cleaner, greener and saving you money!

Our boiler servicing will involve fully inspecting your boiler both inside and out. Some National Companies do the minimum to meet legal requirements. We are thorough, complete and check every part to ensure your peace of mind and safety. Our boiler servicing can take up to two hours to complete. We guarantee a first class service, our reputation depend on it.

SEDBUK was developed under the Government’s Energy Efficiency Best Practice Programme with the co-operation of boiler manufacturers, and provides a basis for fair comparison of the energy performance of different boilers. The following link gives details of boiler efficiency.

http://www.sedbuk.com/

There is also a cost calculator so you can check how much future gas prices will cost you.

We will balance your boiler output to supply heating to all radiators in the most efficient way. With the correct chemical inhibitor treatment, correct pump speed and radiator valve settings it is easily possible to improve boiler efficiency by up to 20%.

Central Heating system improvements and Control Upgrade

The addition of a filter within the central heating circuit can improve boiler efficiency by up to 6% [£60.00 per year for a three bedroom house]. This can also extend the lifespan of the boiler, pump and radiators by five or more years. This could save you an additional £500.00 based on the replacement cost of a new gas boiler, pump or radiators.

Your home will get warmer quicker and the temperature levels will be better matched to the needs of your home. You will be more comfortable and saving money!

A £150.00 spend could save you £800.00 over five years. A much better rate of return than any Bank or Building Society could offer.

We offer a range of radiator valve options that let you control each radiator by timer control. This can save up to 20% of boiler operation, without heat level reductions in the rooms in use during day and night. A £300.00 spend could save you £200.00 per year; making you £700.00 better off after 5 years.

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.
