Warmer water means
more swimming.
Most people like their
pool to be heated to around 28 deg C.
Last year (2017) the UAE
mean temperature for the summer was just below 20 deg C.
That means that your
outdoor pool is going to need heating if you are going to enjoy using it.
Traditional methods of heating the water as it is circulating would be by
electricity, gas or oil fired heaters.
All these methods use
up fossil fuels and generate emissions that we are all trying to avoid. And
they all cost money.
Heat pumps aren’t
magic. They aren’t free to run but they do something very clever. They multiply
the heat that is produced by a unit of energy.
And rather strangely,
they do it by refrigeration.
How do heat pumps
work?
There are various
different types of heat pump but the one most commonly used for a swimming pool
installation is an Air Source Heat Pump.
This type of heat pump
uses the heat in the atmosphere, the warmth of the air itself, as a source of
heat that it then transfers to the water in your pool.
Outside air, at any
temperature above freezing, contains some heat. For instance, the air of last
year’s summer contained an average of 20 deg C.
A heat pump extracts
that heat from the air. That is to say, it uses refrigeration technology to
cool it down. You see the fridge in your kitchen doesn’t add ‘coldness’ to the
food and drink inside it; it removes heat.
Your domestic fridge
just radiates that heat out into the air, a heat pump uses a heat exchanger
coil to put the heat where you want it; in this case, the water in your pool.
The heat pump uses
electrical energy to run but an efficient heat pump will produce up to 4Kw of
heat energy from every 1Kw of electrical energy.
Some electricity is
used to drive a fan that sucks air into the unit. That air then passes over a
CFC free refrigerant gas, warming it up. Electricity is also used to drive a
compressor. As the gas is compressed, so its temperature goes up and the hot
gas is passed through a heat exchange coil, warming the water in your pool.
Of course, heat pumps
will find it easier to pull energy from warmer air than from air that is cold.
If they are used to ‘top-up’ your pool’s heat in the summer months, then this
isn’t a problem.
Air source heat pumps
can last over 20 years with very low maintenance requirements – the fridge is
the most reliable appliance in anyone’s kitchen.
Using a heat pump to
warm your pool.
Heat pumps are
relatively inexpensive to buy, install and of course, run.
Most installations
will have a secondary source of heat for the pool, as a heat pump will not be
able to heat a pool up quickly or be able to provide enough heat in some colder
conditions.
Heat pumps come in a
variety of sizes and a reputable dealer will recommend one that is appropriate
for the size of your pool.
Most heat pumps are
very reliable but a long warranty is a sign of a high quality swimming pool
heat pump.
Total Pool heat pumps.
Economically priced
and suitable for all types of outdoor swimming pool, Total Pool heat pumps benefit from oversized, titanium
heat exchangers making them highly resistant to corrosion by salt, chlorine and
bromine.
Both models are suited
to UAE climate with the Total Pool able to provide all year heating capability
and show a significant saving on energy bills. In fact, Total Pool heat pumps
can save you up to 83% in operating costs and The heat pump can pay for itself
in just a few years with the cost savings.
Highly efficient and
economical, for each 1kW consumed by the Total Pool heat pump, 6 kW can be returned to the pool.
So 5 out of 6 kW are for free.
