Cover up your
assets!
Whilst fitting a pool cover won't allow
you to enjoy all year round swimming, it will
provide you with a number benefits plus save you
a lot of time, effort and ultimately money in the
long run.
Covering up your pool is an obvious energy saver.
Swimming pools lose heat in a variety of ways,
but evaporation is by far the greatest source of
energy loss. 70-90% of heat loss is due to
evaporation so a pool cover of some kind is the
first step towards energy savings.
The type of cover you go for will depend on your
budget, but as with most things in life, you get
what you pay for.
The simplest is an instant ‘cover’
like Heatsavr, a bio-degradable liquid which
prevents the water from evaporating. The liquid
is dosed into the pool on a daily basis and works
by forming a one molecule thick layer on the
surface of the pool whenever it is sufficiently
calm. Although this microscopic layer can’t
be seen, it is sufficient to reduce evaporation.
Heatsavr breaks apart whenever the water is
disturbed but reforms as soon as the water
becomes calm again. Thus Heatsavr is a flexible
cover, working whenever and wherever the pool
surface is not too disturbed by swimmers. The
other good thing is that this type of cover suits
any size or shape of pool and by using a
programmable dosing system its use is fully
automatic.
The next step up in covers are the solar
‘bubble’ covers which will reduce
evaporation and maximise heat gain from the sun.
Choose a good quality cover of 500 or 600 microns
which is chlorine resistant so that the cover
retains its colour and does not go brittle and
crack before the season is out.
The better quality solar bubble covers also
contain UV protection which will prevent the sun
from bleaching the cover. Choosing a light colour
allows the sun’s rays to heat the pool more
quickly. Heat retention covers are generally only
used for indoor pools as the opaque darker
colours do not allow the sun’s energy/light
to pass through.
If you have a more to spend, a material or fixed
slatted roller cover will also prevent
evaporation aswell as heat loss and provide
additional safety benefits too, giving you all
year round piece of mind, particularly if yours
is a family pool. If money is no object, at the
top end of the market, a number of these covers
will be fully automatic meaning that material
roller covers close in just a couple of minutes
with slatted covers not far behind.
Fitting of either type of a roller cover can be
carried out on existing pools of almost any shape
or size including more recently infinity edge
pools although some retro fits may have to have
the stoage of the cover above ground at one end
of the pool. For a new pools, this
shouldn’t be a problem as any design should
incorporate in-ground storage for a cover into
initial plans.
Particularly environmentally friendly covers are
those which are fitted with a small solar panel
on the end of the reel. Although these covers
still need alternative energy (battery or
electricity) it does mean their operation demands
minimum traditional energy in sunny weather.
Whichever type of cover your budget allows for
– be it manual or automatic, slatted roller
or material – there are of several
companies in the UK which supply a fantastic
range of covers and by having one, your pool
water will be cleaner. That means a saving of
your time, your money and the environment too!
