Good Radiators Make Effective Central Heating Systems

Take a modern car as an example. The engine creates the power by burning fuel. The power is then transferred by the wheels and tyres to pull the car forward. In the central heating world, the engine is your boiler and the wheels and tyres are your wall hung radiators. Just like in cars, a well designed and sized radiator is crucial for effective heat transfer from the boiler into the room and as such guarantee an effective and economic performance of your central heating system.

It might come as a surprise that those sleek looking stainless steel radiators offered by most UK plumbing and heating merchants date back more than 150 years. The first radiator was registered as a patent in 1855 by Franz Sangalli, a German engineer. In effect, despite considerable visual differences, the main working structure of the radiator is the same as the ones registered initially by Mr. Sangalli. The radiators are effectively a hollow case made of metal, shaped as a flat box and attached to the wall to maximize radiation of heat into the room.

Most UK made radiators are constructed from sheet metal with brazed fins (normally internal within an outer casing). Using a simple pump (normally located in the boiler or by the hot water cylinder), hot water is circulated through the central heating loop. The hot water is pumped into the radiator and gradually loses its heat to the surrounding atmosphere. As the water cools off it drops and eventually is pumped out via the return valve (normally at the bottom of the radiator). The air surrounding the radiator absorbs the heat from the water within the radiator and rises to the top of the room. Consequently, cooler air is drawn towards the radiator to get heated up. This convection effect is a simple physical phenomenon that keeps our homes warm in the winter.

Radiators, though tried and tested over many years, still suffer from typical problems from time to time. One of the most common problems is the air pockets that develop within them. These small pockets can be a result of tiny bubbles of air creeping into the sealed central heating system through tiny cracks. Professional central heating installers minimise the risk of such cracks by using compression fittings or other solution to ensure the connection points are free from potential cracks.

Another common explanation for these air pockets it that they are the result of a chemical reaction that occurs when copper piping and other metals come in contact with very hot water. Such pockets (normally made of hydrogen) get trapped inside the system and find their way to the top most point of the system. This is why your radiator does not get hot at the top side, as it is filled up with air pockets rather than hot water. As this reduces the efficiency of the radiator and the central heating system as a whole it is recommended to bleed out such air pockets from the system. This can be easily done by using a bleeding key (which can be purchased in all major DIY stores in the UK). The bleeding key fits into a bleeding screw at the top of the radiator that lets the air pockets escape and return the system to good operating mode.

Another common problem affecting radiators is a build up of sludge. Since hot water rubs against iron, copper and other metals within the closed central heating loop, the resulting chemical reaction creates not only gases but also chemical deposits. Such chemical deposits remain in the sealed system and clog the pipes, reducing their performance and effectiveness.

Such corrosion can be addressed and prevented by ensuring that the plumber installing your central heating system adds a chemical corrosion inhibitor into the closed circulation loop. Prior to doing this most plumbers these days go one step further and actually power flush the system to remove any build up and debris that might have accumulated within the pipes. Even new systems may require a power flush to remove debris that has been there as a result of the manufacturing processes of the pipes and the radiators.

How Can Landlords Keep Their Tenants Warm This Winter?

Insulation doesn't need to cost landlords the earth

The big issue that landlords have with the laudable aim of energy conservation is that, whilst the capital investment is incurred by them as the landlord; it is the tenant that effectively receives much of the financial benefit in the form of cheaper heating bills.

However, what landlords may not realise is that recent changes in the tax system means that individual landlords (and other landlords who pay income tax) who let residential property and install loft insulation, cavity wall insulation and solid wall insulation to properties have been able to claim a deduction in their income tax bill, this is called the Landlords Energy Saving Allowance (LESA).

The maximum amount which can be claimed is £1,500 per property. Following the 2006 Budget, from 6th April 2006 the Landlords Energy Saving Allowance (LESA) has been extended to enable landlords to also claim the allowance for expenditure from installing draught-proofing and for insulating hot water systems in dwelling houses which they let.

Further information is available from Her Majesty's Revenue and Customs.

Landlords do however need to be wary that they do not by improving their residential investment properties insulation, then cause damp problems through inadequate ventilation.

IMPROVING THE HEATING

The other way a landlord can keep their tenants warm and happy is by improving the heating. The vast majority of housing including buy-to-let investment properties now have central heating. In 2005 the English House Condition Survey found that just under 9 out of every 10 properties (88%) had central heating a further 7% had storage heaters.

The reality therefore for most landlords is that an improvement to the heating system involves an upgrade to the central heating system. The efficiency and effectiveness of a heating system largely depends on the type and age of the boiler, with most boilers lasting between 10-15 years. The difficulty for many landlords can be deciding when to upgrade to a new model. I was faced with this exact conundrum recently. I had a problem with a 10 years old boiler which packed up depriving tenants of hot water & heating making prompt action vital. The plumber suspected it was one of two parts the gas valve or the PCB board, both costing over £150 with fitting costs on top.

What did I do? Risk having one part fitted to find out it was actually the other that needed replacing? Then potentially having replaced 2 parts would I have been better off having a new boiler fitted at the outset? In the end I contacted the manufacturer and their technical department were able to run through a few diagnostic tests to pinpoint the part I needed. I am now hoping that the boiler lasts several years longer before it has to be replaced by a new condensing boiler.

Condensing boilers

Many landlords may not be aware that since the change in the Building Regulations in 2005 all newly fitted boilers have to be high efficiency, which generally means condensing boilers.

Condensing boilers are have also required to be fitted in Scotland since 1st May 2007 with the revision of section 6 of the Building Regulations.

A high efficiency condensing boiler works on the principle of recovering as much as possible of the waste heat which is normally rejected to the atmosphere from the flue of a conventional (non-condensing) boiler. The best high efficiency condensing boilers convert more than 90% of their fuel into heat, compared to 78% for conventional types. I found this useful site for a ranking of boilers in relation to their efficiency.

How do they work?

The extra efficiency is accomplished by using a larger heat exchanger or sometimes two heat exchangers within the boiler, which maximises heat transfer from the burner as well as recovering useful heat which would normally be lost with the flue gases. When in condensing mode (condensing boilers do not condense all the time) the flue gases give up their 'latent heat' which is then recovered by the heat exchanger within the boiler. As a result the temperature of the gases exiting the flue of a condensing boiler is typically 50-60°C compared with 120-180°C in a current non-condensing boiler. At the same time an amount of water or 'condensate' is produced.

The fact is if a landlord's boiler is between 10-15 years old then it probably is not efficient by modern standards. Replacing a landlord's old boiler with a new high efficiency condensing boiler is likely to save around a third of the heating bills straight away.

Costs

A new condensing boiler will cost about £750 inc. vat for a decent make.

However the additional plumbing kit will probably cost another £250 and then there is the fitting costs of at least £250. Bank on at least £1250.

Having purchased a new boiler landlord can then insure themselves against further maintenance costs by taking out boiler insurance.

I would caution landlords from automatically taking out this type of cover without carefully considering the benefits. This is mainly that it guards a landlord against an unexpected large bill. If a landlord's cash-flow is stretched then this might be the safe option. However landlords should appreciate that at a minimum of £100 pa the cost of the insurance over the lifetime of the boiler would amount to the entire replacement cost. Therefore, they may be better off setting up a monthly 'sinking fund' equivalent to that of the insurance. This way they can build up a cash fund that is available should disaster strike. Should this not happen then the money can go towards the eventual replacement cost of the boiler.

One thing is for sure, keeping the tenants warm and happy this Winter isn't getting any easier or cheaper!

How A New Boiler Can Save You More Than A Third Off Your Heating Bill, And What To Look Out For

If you live in a climate with cold winters, your central heating boiler is by far the most energy-hungry appliance in the house. A boiler in the average UK home burns over £500 worth a gas each year, and is responsible for emitting almost 4 tonnes of carbon dioxide into the atmosphere. As high energy prices hit householders in the pocket, and more and more people are becoming concerned about Climate Change (caused by the burning of fossil fuels like gas), many people are finding that it makes sense to install a new boiler.

Older boilers waste heat and money every time they fire up. This is because a lot of the heat that is generated from burning the gas is lost up the chimney or flue. Modern boilers are much more efficient because they recover and recycle a lot of this heat, and so need to use less gas. This can save you up to 40% or £200 a year off the average UK gas bill.

The most efficient type of boiler is a Condensing Boiler, which now achieves almost 90% efficiency on the fuel it burns, far higher than older boilers. They normally cost a bit more than other types of boiler up front, but save a lot of money in the long run because you spend less on fuel. The most common alternative is called a Combination Boiler, which activates on demand, which means less wasted energy and no need for water tanks or cylinders. Although not as energy efficient (at 75% efficiency) or cost efficient as the condensing boiler, combination boilers do require less of an upfront investment. Most organizations recommend that people choose a condensing boiler, and indeed building regulations in some countries now make this obligatory.

How do you know if you would benefit from a new boiler? If your boiler is old, especially if it is 10 years or older, a new boiler could well make great sense. But you don’t need to try to work this out yourself. Many large, reputable heating companies offer free, no obligation boiler and heating surveys, and they can tell you how much you will save and exactly how much the installation of a new boiler will cost. You can easily sign up for a survey on-line, through a web-site such as Downwithco2.co.uk.

Before you finally choose your new boiler you should think about a few things:
- How big a boiler do you need? How much hot water can satisfy the needs of your household?
- Even though condensing boilers are the most expensive, they are more efficient than other boiler types and in the long term, could save you the most money.
- What will the boiler be used for? Will it be used for space heating, or just hot water?
- What type of fuel do you have available? Wood, Natural Gas, Fuel oil?
- After the boiler has been installed, who will take care of it? Many companies offer maintenance contracts, and often these are a good idea.

When thinking about a new boiler, you should always make sure you are dealing with a reputable and qualified firm. Installers should be registered with an official organisation. This is especially true with gas boilers; in the UK you should always make sure your gas boiler installer is ‘CORGI’ registered.

In some countries like the UK, a new boiler can make even more financial sense because the government subsidises their installation, in order to promote energy efficiency. Your installer should be able to tell you about these subsidies, which apply to almost everyone in the UK, especially older people who qualify for even more money off a new boiler.

Finally, if you want to save energy and money off your heating bills, you should also think about having your home properly insulated if you haven’t already. This is now very good value, and pays back the up-front investment in under 2 years. Further information can be found at downwithco2.co.uk

Residential Boilers

In the United States most households are equipped with residential boilers. They transmit the heat required to operate water heaters and heating systems, providing relief from chilly winter conditions. Residential boilers are used for heating purposes in buildings and are immensely of great use to the people. Residential boilers include Category I type of boilers. Non-positive vent pressure and non-condensing and incorporate natural draft appliances mark them.

In residential boilers the heat exchanger integrates the heat transfer competence of copper-finned tubes with the mass of two cast-iron wet walls encasing the combustion chamber. The units are readily obtainable in a variety of sizes to fit almost every residential heating load. Residential boiler systems are known for their high degree of operational efficiencies that can reach up to 84.5% AFUE. Most of the residential boilers have certain exclusive features including boiler-mounted induced draft fans to aid in sidewall-vented installations.

Residential boilers are characterized by clean combustion. They have an immensely high level of efficiency. Since they are meant for residential purposes they are known for their economical operation and longevity.

Residential boilers are flawless central heating sources for single- or multiple-family homes. They ensure consistent heating for a long time. Most modern residential boilers are compact in design and use the most sophisticated combustion and manufacturing technologies.

The efficiency of certain residential boilers can be as impressive as 98%. Most residential boilers are self-adaptive in structure and compatible with varying conditions. Ideal residential boilers integrate the immense effectiveness of modern copper boilers with the long-life consistency of cast-iron boilers.

Most residential boilers are equipped to meet the most demanding challenges of heating uses.

What You Don't Know Can Hurt You - Information Is Power

They say it quite often - Information is Power. But is the opposite also true? Is lack of information something that makes you powerless? Can what you do not know hurt you? Indeed it can and yes the opposite is also true. Worse off acting on bad information is very similar to acting on no information. For this reason is makes sense to never stop learning, to learn something everyday and make knowledge a priority in your life.

So many times we see that once people leave high-school they never pick up and read another book. That is a travesty and perhaps why the average reading level in the United States is just about at the Eighth Grade Level. But you must not be too alarmed as that is one of the highest of all nations of the World. In many nations 50% or more of the population, cannot read or write. Imagine the disadvantage. Are you beginning to see how knowledge and information is power?

Now the next thing we need to discuss is your information strategy. How do you get your information? Is it a combination of friends, TV news, newspapers, radio, industry trade journals and books? Which is the best way to get good solid information? Well TV might be a little problematic and chances are your friends like to sling a little bull too. Trade Journals are good as the rest of the industry reviews them and they better be or they will say something.

Profit from Your Own Information Empire!

Would you like to profit from your own information empire? Here are a few ways of doing so.

1. Book Distributorships

For free or nominal consideration, you can obtain book dealerships which allow you to sell books and other information products. For example, you can buy books at a cost of fifty percent of the selling price. In many cases, you don`t even have to stock the product; your supplier will drop ship it for you.
