Human Thermal Comfort Or Just Using A Doggy Blanket?

/0 Comments/in /by

“Where have all your shaggy dog stories gone?” asked a customer when calling up my master, Bernard, to take a look at their boiler, which had decided to give up the ghost just before Halloween, woof, woof!

If only I had a shaggy coat like some of my other canine pals. The clocks have gone back and the long, cold dark nights are drawing in. Luckily I have a big, warm doggy blanket and, of course, Bernard has checked every last valve and connector to make sure our heating system works perfectly.

It’s not just a matter of swapping energy suppliers

With energy bills soaring, it is now more important than ever for our homes to be energy efficient and not waste one kilojoule. It’s not just a matter of keeping the costs of bills down by swapping energy suppliers but also having the right type of boiler, and ensuring it’s checked and regularly maintained so it works to maximum efficiency. This is especially important during the winter months of heaviest use.

Humans always expect their central heating system to work and constantly provide the required level of warmth, when required. But to do this, a central heating system must firstly be well-designed and efficient, which means all the components, such as the thermostat, boiler, radiators, and pipework are in perfect balance to produce the desired “thermal comfort.”

Thermal comfort factors

“Thermal comfort” is defined as the measure of satisfaction achieved when a desirable heat balance between the body and surroundings are met – such as resting on my blanket just in front of the radiator!

For human thermal comfort, the conditions are not so easily satisfied. There are several factors, which influence the ability to achieve a comfortable level:

– Air temperature at floor level should not be greater than 30 C below that at head level

– Airflow around the body should be horizontal and at a rate of between 0.2m and 0.25m per second. A variable air velocity is preferable to a constant one.

– Room surface temperatures should not be above the room air temperatures.

– Relative humidity of between 40 – 60 per cent.

– Air temperatures should be between 16-220 deg.C, dependent upon the type of activity being carried out, age of  occupants and the quantity and quality of clothing worn.

Home value and energy efficiency

A degree of control over all of the above factors can be applied by insulation, draft reduction, control of condensation/ventilation as well as the heating. No two properties are ever alike – I know because I’m often allowed to sit in the van!

Ensuring hot water and thermal comfort heating to all parts of a home whenever it’s needed is more than just putting a boiler in and joining up the pipes. These days, the value of your home is bound up with how energy efficient it is at providing thermal comfort.

But not too bone dry – but that’s a pun better off buried. Hey its Halloween…woof, woof!

Peace Of Mind Guaranteed Or Counting The Cost Of A Cowboy Plumber

/0 Comments/in , /by

“It’s enough to make you barking mad!” says the master who just came across a recent survey, which reports that nearly 70 per cent of people admit they choose their plumber “on cost alone”.

According to a study of around 2,000 consumers, finding a cheap plumber trumps any concerns over whether they are registered with Gas Safe and other approved contractor schemes or even if they have any professional training or qualifications.

The master says quite rightly that it’s the “cowboy” element that constantly gives the professionally trained and qualified trade a bad image. Incredibly, the survey found that nearly a quarter of the people polled said they “have fallen victim to a rogue plumber” and a further quarter know someone else who was also caught out by a botched plumbing job.

Trying hard to cut back on unnecessary costs

The master knows that times are tough and everyone is trying hard to cut back on unnecessary costs. So it can be a real disaster in more ways than one if you wake up in the morning and the house is cold and there’s no hot water. The challenge of a repair or replacement of a boiler that has suddenly “stopped working” can be seen in different ways by different people.

For far too many, their response means they seem willing or oblivious to suffer costly problems weeks or just days later. More than 50 per cent said they are prepared to risk asking an unqualified person to carry out plumbing work in their home. So it should come as no surprise to find that 80 per cent of those asked also said they “don’t always expect their plumber to do a good job.”

Hot water and heating vital to everyone’s daily lives

The proper, legal and safe functioning of gas or oil fired hot water and heating systems are vital to everyone’s daily lives. Yet the necessary training, qualifications and experience required to ensure that the systems do work are considered of less importance than finding the cheapest quote and accepting a substandard, even dangerous level of workmanship.

Consequently, nearly 70 per cent of those surveyed also stated they always get a second opinion to see if they’re being charged the “going rate”.

The master absolutely agrees with customers being careful to see that the quotes they receive do generally reflect a genuine, accredited industry level of service quality expected of a fully qualified and experienced plumbing and heating installer.

Guarantee

Today, a boiler can account for more than half of a household’s total energy bill, and energy prices are set to continue to rise, so having a properly functioning and efficient boiler is vitally important. Installation of a quality, energy rated boiler can now be guaranteed for at least 5 years by a fully compliant plumber.

Can you say that about your boiler?

I say “woof, woof” – if the master has done it for you – and I’m definitely not barking mad!

Avoid The Winter Call Out – Check Your Central Heating Now!

/0 Comments/in /by

Grrr ….gas price rises coming thick and fast now! It’s not simply a problem of finding the extra money to cover the winter quarterly bill. Every year millions of customers face a crisis when the boiler packs up unexpectedly – just when a cold snap arrives or worse, the night before Christmas!

If the cold snap lasts as long as they have been doing in the last couple of years, then all sorts of unexpected problems can occur. It’s simply staggering how many emergency call outs there are every day as it starts to get colder from November onwards.

But as daily gas consumption rises more boilers break down. The rise in energy prices have also meant that people have, increasingly, delayed turning on their heating.

One in six consumers will wait until November before putting the central heating on for the first time since last winter while three per cent will keep putting another jumper on until December or until the first sign of frost, and one per cent hold out until snow arrives!

But the added delay also increases the likelihood of storing up more problems with the boiler, radiators or pipes just when they need to be fully working and providing heat.

Before temperatures start to fall…

The master always advises customers to have their boilers and central heating checked over before temperatures start to fall . It’s so much easier to fix a boiler or water flow in milder weather than when temperatures are below freezing and there’s the possibility of a blockage.

It’s easy to simply forget about the heating system but there can be so many things that can go wrong simply because the system has “not been looked at for a while.”

Most people know about radiators failing to heat up because of corroded pipework causing a blockage of sludge in the system, which prevents the free flow of hot water.

But many people will simply leave the boiler set to ‘hot water’ all summer and then switch to both ‘hot water and heating’ when they feel the first nip in the air. What actually happens is that a valve turns to allow the water out to the radiators but if the valve has been damaged or simply stopped working during the year, then the first time it’s realised there is a problem is when the radiators fail to warm up.

So many things that can go wrong…

As well as a failure of motorised valves, no heat or hot water could also mean broken diaphragms and airlocks, a faulty thermostat or low water levels. A boiler which keeps switching itself off could also mean a problem with the thermostat, or the pump not circulating the water in the system properly.

Low water pressure is another possible cause. A water leak in the system is the most common reason for a loss of pressure, but a pressure relief valve may need replacing, and leaks and drips can be caused by a variety of issues.

And those strange banging, whistling or gurgling noises you hear when you’re trying to get some sleep at night? Once again it could be low air pressure or most commonly, air in the system or the build up of lime-scale in the boiler’s heat exchange.

There’s so many things that can go wrong which can so easily be avoided with a pre-winter check up!
The master is always right – he should know, of course, he is a fully qualified Gas Safe plumber!
