Which radiators are most efficient?

Andy — Tue, 20 Sep 2011 14:42:30 +0000

The question “which central heating radiators are most efficient?” is not straight forward, as in this context the word “efficient” means different things to different customers.
An official definition of the word “efficient” is:

“Acting or producing effectively with a minimum of waste, expense, or unnecessary effort.

It can be argued that all central heating radiators are equally efficient insofar as the energy put into a radiator will equal the amount of heat it gives out. In other words, all properly functioning radiators with same heat output capacity, will give out the same amount of heat as one another and will use the same amount of energy to do so.

Radiators are just vessels designed to release energy in the form of heat. The amount of heat they release will depend on the amount of energy put into them.

In asking “Which central heating radiators are the most efficient?”, customers could mean:

1. Which radiator gives out the most heat for its size?
2. Which radiator is the cheapest to run?
3. Which radiator wastes the least fuel?
4. Which radiator heats up the quickest?

Relevant factors to consider in answering the above questions and ensuring you get the right radiator(s) for your specific needs are considered below.

Size and surface area

Its surface area determines the maximum heat output capacity of a radiator. The larger the surface area, the higher the potential heat output.

Surface area will be greatly increased by convectors, fins, or double or triple panels. So for example, the heat output capacity of a flat single panel radiator will be considerably less than a radiator of the same size (height x width) with double panels, and/or convectors or fins.

When considering one model of radiator, then generally, the bigger the radiator, the bigger the heat output. However this is not necessarily the case when comparing one model of radiator against another.

Water content

In theory, the less water a radiator holds, the less time it takes to heat up, and the less fuel is would require to reach full temperature. Consequently, the lower the water content of a radiator, the more “efficient” it could be considered to be. However, in reality, there is little difference in the level of water content across radiator models, although over an entire system the slight variation would multiply.

Design

The shape of a radiator and its design does have an effect on the amount of heat it radiates, but again this is due to the particular surface area of the model. For example, a tubular radiator with hollow tubes offers a lot more surface area than a flat panel design without fins as the heat can be emitted from both the outside and the inside of the tubes. So the design of a radiator does have a direct effect on its maximum heat output.

Material

A radiator’s material of manufacture does not have a direct impact on the amount of heat it gives out. However, the material will be a determining factor in the speed in which the radiator heats up and cools down. For instance, aluminium heats up quickly and cools down quickly, whereas cast iron heats up at a slower rate and cools down at a slower rate.

Finish

Science proves that the finish of a radiator affects its heat output in varying degrees.

There is a principal known as “emissivity” that enables experts to measure the ability for heat to leave (or radiate from) the surface of an object.

Levels of emissivity vary between finishes of radiators. Painted radiators have a higher level of emissivity than bare metal radiators, meaning that painted finishes absorb and release heat more than bare metal finishes. Matt finishes have a higher level of emissivity than gloss radiators. Even the colour of the finish can affect the level of emissivity. For instance, black paint has a higher level of emissivity than white paint. However, the difference in the emissivity of radiators is negligible and would only be realised in laboratory conditions.

Only a chrome finish has a noticeable affect on the heat output of a radiator as chrome has a very low level of emissivity. The chrome coating works on the same principal as the space blankets (the silver insulation blankets) used to keep athletes warm. The chrome coating, whilst looking beautiful, does reduce the ability of the radiator to radiate heat. Chrome (chromium plated) radiators are proven to emit approximately 20% less heat than the equivalent sized radiators in a painted finish.

In theory, the optimum radiator when looking for high heat output and rapid heat up time, taking all factors into account (no matter how minimal their impact) would be a matt black aluminium radiator with the greatest surface area for its size.

In practice, there are many other aspects that will determine the best radiator(s) for your project, including, aesthetics, dimensions to fit your space, budget and availability. Your choice will be governed by which factors take priority.

Self Build & Home Improvement on the Increase

Andy — Tue, 18 May 2010 07:44:40 +0000

Interest in both self build and home improvement continues to grow, according to a recent survey from The National Homebuilding & Renovating Show. Twenty nine percent of visitors to the Show, held at the NEC in March, are currently involved in a self build project, compared to 20% in 2009, with 38% involved in a renovation project, compared to 34% in 2009. This homeowner confidence is mirrored by recent news from the Nationwide that house prices in the UK have risen by 10.5% in the year to the end of April.

Homeowners keen to improve, extend, renovate or even build their own home should visit The Southern Homebuilding & Renovating Show , on at Sandown Park on 26 and 27 June.

Don’t despair, save your sofa and become part of the new Make Do & Mend Generation with the innovative new leather recovery patch from MastaPlasta!

Mastaplasta

More than 75,000 sofas are thrown away each year by Britons and research published recently by the Department for Environment, Food and Rural Affairs showed that an additional 500,000 tonnes of household waste could be saved from landfill by doing more to reuse, repair or find new homes for your old settees and armchairs. MastaPlasta is an inventive new way to save your sofa from scuffs, holes, rips and stains.

Easy, inexpensive and good-looking, the plasta can be attached to any surface, covering a tear in seconds. Incredibly hard-wearing and durable, a MastaPlasta “Band-Aid” is engineered to last and not peel off, making it the ultimate new accessory for those who want to waste less and recycle more, beautifully.

MastaPlasta patches are available in small, medium or large and cost no more than £8.95 each. With the choice of six different designs, rectangular or circular shapes and ivory or brown colourways, there will always be a plasta to suit. For those wishing to hide the rip as discreetly as possible there is the ‘plain stitch‘ design, alternatively why not make a feature out of it and apply a design to suit your personality!

MastaPlastas are suited to PVC and upholstered sofas as well as leather, but their abilities don’t just stop there. Apply to luggage, jackets, handbags, car seats or anywhere for a quick and easy solution to life’s little mishaps or to personalise your belongings.

London Show Reflects Trend of Home Improvement Increase

Andy — Tue, 09 Sep 2008 16:06:19 +0000

Five interest rate rises in almost as many months, recent flood damage and a cooling property market have caused homeowners to take a long hard look at their most important asset. For many, moving house is no longer an option and making the most of their current home is the most sensible strategy. This trend has been confirmed in a recent survey by the Halifax revealing that home improvements have increased in popularity by 12 % on last year’s figures as more than half the population (58%) have undertaken some form of home improvement in the past 12 months. These figures are borne out by research carried out at the National Homebuilding & Renovating Show in March where 44% of visitors described themselves as home improvers, up 6% from 38% at the London Show in September 2006. This is surely welcome news for anyone working in the property industry.

The organisers of the London Homebuilding & Renovating Show, on at ExCeL from 19 to 21 September, had already identified this trend and have focussed heavily on home improvements at the Show. The Move or Improve? Pavilion will feature a number of specialist companies covering all aspects of home improvement and Michael Holmes, presenter of the ITV programme ‘Don’t Move, Improve’, will be presenting a daily seminar on ‘Renovation Do’s and Don’ts: The Key to Successful Home Repair, Extension and Conversion’. There will also be a full day of twelve free Renovation Masterclasses on Sunday 21 September.

“We could see the direction the market was taking and wanted to make sure the Show reflected this” said Show Director Nick Noble, “We feel it is important to offer both our consumer and trade visitors a wide range of products and services that focus on renovation and home improvement. Our research revealed that 75% of visitors see updating a kitchen or bathroom as the most important project following by 72% interested in extending their property and 62% seeking to convert a loft or basement.”

The London Homebuilding & Renovating Show also boasts the Eco Homes Zone, the T3 Smart Home Zone and a wide range of self-build exhibitors. Over 220 national and specialist companies will be on hand to offer the latest products, innovations and services. Free seminars and exhibitor-led masterclasses will help visitors to plan their projects. The seminars take a broad overview on a range of topics whilst The Masterclasses concentrate on a different specialist area each day of the Show – Friday is Eco Day, Saturday is Self-Build Day and Sunday is Renovation Day. In all there is an incredible total of 72 free sessions during the three days of the Show.

The London Show takes place at ExCeL from 19 – 21 September and will feature over 220 exhibitors, 12 free seminars and 12 free masterclasses every day offering an unrivalled source of information and advice under one roof. Tickets are £8 in advance or £12 on the door (children under 16 go free). For more information and to purchase tickets visit www.homebuildingshow.co.uk or phone 0870 906 2002.
