thermostat Archives

Are we going to see a repeat of prolonged, freezing Arctic conditions in the winter months ahead that we’ve experienced in recent years? It’s not so bad for me – I love the snow, my legs never shake nor get snow or ice stuck in between the paw pads. What do you call young dogs who play in the snow? Slush puppies! Woof Woof!

So it’s a great, fun time for a dog to be out digging deep in the snow and sniffing out all sorts of strange scents. But some humans can have real problems keeping sufficiently warm in their house if the temperature drops below zero. Even I admit it can be tough trying to break through ice to find bones I’ve buried!

Exceptional problems with keeping warm

So, apart from turning the thermostat down one or two degrees in a bid to avoid a nasty quarterly bill, why should there be a problem with keeping warm if we have one of today’s modern advanced boilers nicely installed?

In the exceptional winter temperatures of recent years, the mercury plunged down between -9C and -20C. However, the average minimum temperature around most of Britain tends to be around 3 – 4C, dipping down to just below freezing when snow is forecast and often for several days afterwards.

Outlet pipe overlooked

This can sometimes mean that the outlet pipe on the modern condensing boiler, which siphons left over cooled water vapour – or ‘condensate’- can freeze if it’s on the outside and not on the inside of the house. This often results in a blockage, which will shut the boiler down, meaning no hot water or heating!

Being a short-haired dog, my master always wants to strap a special doggie coat around me when we go out in the freezing weather. It’s the same, of course, with the outlet pipe. It needs to be properly weather insulated! It’s amazing how this vital pipe can be overlooked because it’s outside.

Usually, a fault code will show on the boiler’s display (or an alarm will sound) and the code can be looked up in the boiler instruction manual.

Unfreezing the blockage

Unfreezing the outlet pipe might not require Bernard to take a look. The blockage is likely to be at the most exposed external point, or at a bend or dip in the pipe. It can simply be a matter of gently thawing the ice.

However, please note – it’s absolutely vital that boiling hot water is NOT simply poured directly onto the pipe! Instead, wrap a soft hot water bottle around the pipe and allow to slowly thaw – and it can take some time! The boiler can be restarted by following the instructions in the boiler manual.

While pipe insulation will help to prevent ice from freezing, when exceptional temperatures occur, it’s always recommended to contact a qualified, experienced plumber like my master Bernard, for further detailed guidance according to your type of boiler, heating system and layout.

Meanwhile, I shall be looking forward to seeing the first snowflakes – I love snacking on the stuff even if humans don’t!

If you saw the recent TV programme in which hidden cameras revealed just how much my fellow canines get so fretful when we are left alone in the house, you’ll understand why Bernard, my master, lets me sometimes travel in his van when he’s away a lot on call-outs.

When customers see me, Bernard is suddenly called upon to give his ‘expert’ advice on the welfare of dogs as well as working out what’s wrong with their boiler! One customer actually asked Bernard if he knew how to keep his dog from barking in the front yard. Bernard told him to put it in the back yard! Woof Woof!

Central heating turned on – nothing happens!

From the start of autumn we are always very busy responding to calls from customers who may have just turned on their central heating for the first time since before the summer months – and nothing happens!

One piece of ‘real’ advice Bernard always gives is to check that your system is still running by putting the heating on for about 15 minutes once a month. It helps to keep the boiler pump free from debris accumulating. At the same time, it’s always worth having the boiler serviced too – just like my seasonal visits to the vets for a check-up!

Whenever there is a potential problem with a boiler, the key advice is to always call a professional, trained, qualified and industry-approved plumber like my master, Bernard.

Many types and brands of modern boilers today are sophisticated electronic systems, which are constantly being upgraded and require their own specialist knowledge. Yet it’s simply staggering how some people think that they can simply get “this mate of a mate from down the road to come and have a look – it won’t cost anything!”

Simple checks that homeowners can do

On the other hand, there are some simple checks that homeowners can do, which can help identify common but very simple and obvious boiler problems that you should be able to fix yourself.

The most obvious is to check to see if the boiler pilot flame is alight or power light is on. A pilot flame can be relit by carefully following the manufacturer instructions while the power on newer boilers may be restored by checking to see if a circuit protection device has tripped and needs to be reset.

It’s not unusual for a meter, which is in a cupboard alongside many other stored items, to have its on/off switch knocked off.

Another simple check is to see if the central heating programmer been set correctly or if an individual room’s thermostat is set too low preventing the heating from coming on. If the system has not been used for a while or if there is a leak, then it’s likely that the boiler pressure is not correct.

Beyond the simple checks described above, no attempt at plumbing DIY should be made with the boiler – especially if it’s a gas boiler! My master always recommends the importance of making sure a gas boiler is checked and serviced regularly in order to cut the risk of carbon monoxide poisoning.

I can normally sniff a biscuit half a mile away and can never understand why some humans can’t do the same!
