Central Heating Radiator Types [type 11, type 21, type 22]

Radiators are available in three main types, detailed as follows:

Type 11 Single panel, single convector. The first digit indicates 1 panel, second digit 1 convector [ridged metal fins on back of radiator]

Type 11 Radiator

Type 11 Radiator

Type 21 Double panel, single convector. The first digit indicates 2 panels, second digit 1 convector [ridged metal fins in middle of radiator, between panels]

Type 21 Radiator

Type 21 Radiator

Type 22 Double panel, double convector. The first digit indicates 2 panels, second digit 2 convectors [ridged metal fins in middle of radiator, between panels]

Type 22 Radiator

Type 22 Radiator

Always check the manufacturers heat output data for each radiator you want to install.

It is also important to compare different radiator styles for heat output. A heated towel rail, as shown below, may look quite big – but often not too good for heating a bathroom.

Chrome Heated Towel Rail Radiator

Sadly heated towel rails are not sufficient to heat a bathroom. It is always worth going for a larger size towel rail, if you intend it to also heat the bathroom. Manufacturers data will confirm the design heat output. Add 25% capacity required if you are hanging towels on it. As radiators can not warm towels and heat rooms very efficiently at the same time.

Please leave a reply or email me at aim.home@gmx.com if you want any help with this post.

I have put a post together giving details of how to choose the right size of radiator for heating a room. The link https://aimhome.wordpress.com/2012/12/30/central-heating-radiator-sizing/

Water Service Pipework Emergency Stop of Supply

During cold weather it is often the most inappropriate time for problems with pipework, taps and appliances. I visit many properties that have either damaged/defective stoptaps/stopcocks or the access to stop supply is obscured by debris in outside meter stopcocks or even fitted kitchen cupboards or heavy furniture for interior stopcocks.The picture below shows an exterior stopcock cover. This cover top may be set at surface level so only the access cover is visible. The position of the stopcock may not be too obvious. Look at the front or back of your property  for a metal or plastic cover about 6″ [150mm] square. You may have a shared supply with a neighbour or a row of properties, depending on the main supply pipework arrangements. It’s always good to check with neighbours, before you stop the supply. It will not be obvious you have a shared supply, until someone complains, after you’ve cut their water off!

Outside Stopcock cover

You may have a modern water meter. If you see a round plastic cover looking like the one below

Water Meter Boundary Box

Water Meter Boundary Box

You will only see the circular plastic cover at surface level of the road or pavement.

You must take care to protect your working area, avoiding hazards to other road users and pedestrians.

The inside of the meter box or cover box may be full of water or other debris. Have plenty of rags and a large sponge handy to clear out the box, so you can see what you are doing.

The picture below shows what you may see once you’ve opened the cover.

Access may be difficult so investing in a stopcock key may well save time and make access much easier.

There are two types of domestic stopcock keys, as shown below.

The stopcock may be of either plastic MDPE [medium-density polyetheline] or brass construction. The pictures below show the most common types.

It is always good idea to check your water stopcock in good weather, to avoid problems with operation in times of bad weather. If you have problems with the functioning of your water supply stopcock, contact the Company who you pay your water bill to.

This link shows a map of Water Company areas http://www.water.org.uk/home/our-members/find-water-company

This link gives contact details for UK Water Companies http://www.water.org.uk/home/our-members/list-of-companies

The Water Company will arrange a visit to rectify or replace your stopcock. During bad weather the maintenance staff are very busy attending to faults and failures. A domestic Customer may have to wait up to a week for someone from the Water Company to attend.

Don’t wait until an emergency to find out your water stopcock doesn’t work.

Please contact me at aim.home@gmx.com or telephone 07901380746 if you need any help or want to discuss issues raised in this post.

Regular maintenance and inspection is not too expensive, and may well save much more if you have problems in times of bad weather.

Water is a valuable resource that must be saved at every opportunity.

Help to save water by undertaking regular maintenance of your supply equipment.

Central Heating: Smart Controls to Save Money

A fully manual central heating can be very inefficient and costly to run. There are a number of measures you can take to improve efficiency and save money.

1 Time Control Clock

Many modern boilers are fitted with an integrated time control clock. Many boilers, especially those more than 5 years old do not have any built in time control.

An independent time control clock is fitted between the fused isolator switch and the electrical connection to the boiler. There are two types of control clock:

Mechanical timer clock.

The Danfoss 103 as shown below was once very popular, and still available if anyone wants one.

Danfoss 103 Mechanical Timer

Danfoss 103 Mechanical Timer

Digital RF* room thermostat.

Digital equipment is now becoming much more affordable. Prices have fallen by 50% in the last couple of years. It is now possible to buy wireless RF thermostats for under £50.00

Danfoss RF Room Thermostat

Danfoss RF Room Thermostat

* RF stands for Radio Frequency [typically 433MHz, with a working range up to 100 meters]

The items above can be combined into a fully digital timer/control/thermostat arrangement [RF programmable room thermostat] as shown below.

Danfoss Prgrammable RF Room Thermostat

Danfoss Programmable RF Room Thermostat

There are three options for the programmable functions. A RF thermostat will only be ONE of the following:

24 hour – one set of time settings will be available for all days of the week. This offers least flexibility of function/lowest cost reduction [if you like a lie in on some days, the heating will come on at the same time regardless]

5/2 day – this offers one set of times for Monday – Friday and the option of different times for Saturday – Sunday. Better than the 24 hour option, but no good if you want to alter different days.

7 day – the best option by far. The 7 day option offers the facility to set different times for each of the 7 days of the week. Fully flexible and gives the option to control heating times around your lifestyle.

The same RF technology is now available for hot water cylinders as shown below.

Danfoss RF Cylinder Thermostat

Danfoss RF Cylinder Thermostat

The standard mechanical thermostat is shown for completeness

Danfoss Mechanical Cylinder Thermostat

Danfoss Mechanical Cylinder Thermostat

The disadvantage of the mechanical setup is that it needs to be hard wired to the boiler controls. The saving in time and materials is much better if a. more expensive,  RF wireless cylinder thermostat is installed due to savings on labour charges.

The most radical and energy saving change to heating controls in recent years are the eTRV [Thermostatic Radiator Valve] and programmable TRV. These two devices offer full automation of each radiator. Before these valves were available it was a major task involving both plumbing and electrical works. at considerable cost, to create separate heating zones.

The eTRV is shown below

eTRV [Thermostatic Radiator Valve]

eTRV [Thermostatic Radiator Valve]

The eTRV is controlled by a remote device similar to a television remote control.

eTRV Remote Control Handset

eTRV Remote Control Handset

The eTRV actuator head can be fitted to many existing standard Thermostatic Radiator Valves. This makes retro-fitting a simple and cheap solution.

Check the link below for the eTRV compatibility guide

http://www.westradiators.co.uk/radiator-valves/e-trv-valve-adapter-list-v3-24-01-12.pdf

Programmable TRV.

The programmable TRV differs from the eTRV in that the time control function is fitted, individually, to each TRV actuator head. The picture below shows a programmable TRV.

Programmable TRV

Programmable TRV

These units again can be retro-fitted to many existing TRVs quickly and at little cost.

The great thing about eTRVs and programmable TRVs is that you can independently switch radiators on and off, regardless of the control settings of the boiler. An example of what can be done is as follows:

Boiler starts at 06:00 and is on until 23:00.

The upstairs TRVs are set to come on at 06:30 and go off at 08:30.

The downstairs radiators are set to come on at 07:00 and go off at 22:00

The upstairs radiators are set to come on at 21:30 and go off at 22:30

From the time settings above the boiler is in operation for 16 hours a day. However 50% of the radiators are only on for 3 hours. The heat demand from the boiler is therfore 100% for 3 hours and 50% for 13 hours.

Typical savings for a boiler consuming 60p worth of gas per hour are 3 x 60p = £1.80 and 13 x 30p = £3.90 total spend = £5.70

If standard radiator valves are installed, without intelligent controls, the same boiler demand would be 16 x 60p = £9.60 almost £4.00 more spent per day, over £27.00 per week, OVER £1400.00 PER YEAR.

With Programmable TRVs and eTRVs costing upto £15 to£40 per unit, they are not cheap. However the cost for a typical property with 3 bedrooms and with 12 radiators would be between £180.00 and £480.00. Still could be £900.00 better off in year one.

Please e-mail me or call me on 07901380746 if you need any further help or advice with heating controls.

Central Heating: S Plan and Y Plan wiring arrangements

There is often great confusion regarding the wiring of central heating systems.

The two most common are known as S Plan and Y Plan. The basic differences are the Y Plan has one three port valve supplying heating and/or hot water. The three port valve can look like a Y shape when looking at the schematic layout of pipework, as shown below.

Y-Plan-Water S-Plan-Water-300x208

The S Plan has two SEPARATE motorised valves, one for heating and one for hot water. These two valves can be independently controlled and switched. It is also possible to add further zones by adding additional thermostats and motorised valves to each circuit.

The wiring of both systems is reasonably uncomplicated if the following diagrams are followed. I have put these together with reference to most popular manufacturers instructions. Trying to mix and match different manufacturers equipment and instructions can be very confusing, and time consuming. The following diagrams are based on a standard 10 way wiring centre. I have included CPC details for all conductors for completeness.

The S Plan diagram is shown below.

S Plan Wiring Centre

The plan above includes provision for a second circulating pump. This may be the case in a larger property where pumped hot water is needed to avoid drawing off too much cold water on long pipe runs from the boiler.

The Y Plan system is less complicated as there is only one three port valve needed.

Y Plan Wiring Centre

The cost savings from installation of thermostatic and timer controls must not be under estimated. I have had Customers who have saved £20.00 PER WEEK in times of peak demand. It should cost between £125.00 and £350.00 to upgrade the heating and hot water control systems. Money well spent, and should be recovered within 12 months due to reduced gas consumption.

Please contact me if you need any further advice or have ideas to improve this article.

I have PDFs for the two wiring centre diagrams. E-mail me at aim.home@gmx.com if you would like copies.

I’ve also included a link to the Honeywell download page. The wiring guide PDF shows details of all available heating/hot water system configurations.

The Cost of Bath -v- Shower

There is a surprising difference in costs between taking a bath and taking a shower. If you pay water rates, you pay fixed charges as detailed below. The published figures are chargeable, regardless of how much water is actually used.

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

However if you have a water meter fitted the cost is directly charged by the quantity of water drawn of to supply your property. There is also a cost for sewerage. This is not metered, but a simple additional cost per m³, as detailed below:

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 table above water costs £0.002458 per litre. This is the total cost of water drawn off and sewerage returned after use.

The average bath takes 150 litres to fill. A cubic meter of water contains 1000 litres. From the prices above the average bath contains 20 pence worth of water.

  • A five minute ‘high-flow’ shower uses approximately 90 litres of water which costs about 12 pence.
  • A five minute ‘standard’ shower uses approximately 50 litres of water which costs about 12 pence.

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 optimum 18 litres per minute. Many operate at approximately 10 litres per minute. This reduces the shower costs to 12 pence [7 pence for water and 6 pence for waste water to sewer]

Compare your costs and see if you are better off with a water meter.

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.

Cheap Lamps May Not Be So Cheap

GU10 Halogen

The best energy saving measure is to switch it off. However we need lighting for modern living and safety reasons.

Commercial electricity costs between 8 pence and 11 pence per kilowatt hour [kWh]

Domestic electricity costs between 11 pence and 16 pence per kilowatt hour [kWh]

GU10 CFL

Looking at GU10 lamps the following cost comparisons can be made

Lamp   Purchase Cost Cost Wattage Cost per 100   hours
GU10 Halogen £0.70 50 £6.50
GU10 Compact   Flourescent £6.50 11 £1.43
GU 10 LED £12.00 7 £0.91
Lamp Running [cost per year] 3 hours per day 6 hours per day 9 hours per day
GU10 Halogen £7.12 £14.24 £21.35
GU10 Compact   Flourescent £1.57 £3.13 £4.70
GU 10 LED £1.00 £1.99 £2.99

GU10 lamps are very popular and can be a costly purchase if the running time in use is not taken into account.

GU10 LED

Looking at the extreme case of nine hours use per day:

The GU10 halogen lamp costs 70 pence to purchase but £21.35 to run. Total annual cost £22.05

The GU10 LED costs £12.00 to purchase but just £2.99 to run. Total annual cost £14.99

The increased purchase cost per lamp gives a year end saving of £7.00 per lamp. After year 1 the saving increases to over £18.00 per year, per lamp as the purchase cost has been covered in year one.

There are many examples of inefficient lighting in daily use. Please contact us on 01782 504503 or 07901 380746 to discuss your requirements. You can also e-mail aim.home@gmx.com to ask any questions or arrange a free survey of your property.

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.
