Apart from being hard work compared to working on modern boilers, there are other reasons why
more and more installer are not keen to work on back boilers.
Recently, the government decided to once again change the
regulations.
As was to be expected, the rules got tougher.
This lead to the bizarre situation that some systems were considered
safe for many years, became technically unsafe. Due to the wisdom of some bureaucrats, we now
have to tell you that what has served you fine for twenty or thirty
years, is suddenly dangerous.
What has happened, is that the
ventilation details have been altered. For many years, if the
ventilation opening was below a certain size, it was acceptable as
long as it worked safely. Today, we have to shut it off if the
opening is below 90% of the manufacturer's advice, end of story. It
does not matter how many years you have had it. It does not matter
if it works safely. We have to shut back boilers down until the
ventilation has been increased.
The result is that when we get called out we have to tell you that apart from repairing your Baxi back boiler,
we have to do extra work. To many people, this will sound as
an excuse for padding the bill. Since few of us are able to explain
the necessity of this, it can very easily and very quickly damage
your reputation when attending back boiler repairs.
One of the problems seems to be that these
boilers suffer more from than other models, is corrosion. The pump
will deteriorate, which can cause the radiators to cool down. It can
also burner to be turned off more and longer, which adds to the
problem. The logical result of this is often that the user turns up
the thermostat. Now you have an increased chance of overheating of
the back boilers themselves.
Another casualty of corrosion
is often the diverter valve. The effect of this is either a more and
more reduced working of the heating and hot water, or the failing of
it.
The valves and the pump are often located in
airing cupboard. Since these are usually the first suspects, they
are the first things I check. So don't be surprised when the chap
who comes out for a Baxi back boiler repair
does not look at the boiler first.
Back boiler ventilation
I have seen too many homes in south east London and Bromley where I went for a repaired back
boiler that had dangerous and potentially lethal defects. The
downside of this type of appliance is that when it is very easy to
keep develop a defect that does not stop it from working, but in
stead keeps going in a dangerous way. You could compare it with a
car that has a fine engine but faulty breaks. It starts fine, it
drives fine, but you run a serious risk of getting injured or even
killed.
What happens is that the lack of ventilation, lack of
service or a small water leak in the heat exchanger can make the
flames "dirty". By dirty I mean producing Carbon Monoxide.
This is why ventilation is so importnt with back boilers. Not only is it absolutely necessary to make sure it works fine,
it also helps to slow down the build up of CO. It only takes a very small amount of Carbon Monoxide to spill into the room
to put your life at risk.
A concentration of 0.1% is likely to make you sleepy, proceeds to render you unconscious and if the
heating stays on, you are bound to end up dead.
You should always have an approved CO detector in a room with a backboiler, and
test it regularly to confirm it works.
If there is any boiler that really needs a full strip down service every years, it is this
type.
Never block or reduce any ventilation openings; they are vital for your safety.
Check regularly around and under the "fire" for lint and dust. The normal working of backboilers turn
them into a natural vacuum cleaner. Household dust, lint and pethair
can clog up the ventilation openings. If you see any lint or hair,
brush it off gently with a soft brush, or carefully hoover it up.
If you are not sure your backboiler is working
safely, contact a professional for advice.
