Swimming Pool Scene ENERGY EFFICIENCY


Pool Quest In search of the perfect, environmentally-friendly pools…


ABOVE: This award-winning luxury 16m x 4.2m pool by Portrait Pools features a custom manufactured Heatstar Phoenix climate control system with a special ‘quadruple’ stage air heating battery and up-rated air fan system.


Heating a large body of water to a usually high temperature, and then dealing with the environment that it creates, makes a swimming pool one of the largest consumers of energy. However, in pursuit of the perfect energy effi cient pool, there are ways of reducing energy consumption by using advancements in technology.


Commercial pool operators and home pool owners could expect savings of 60% - 70% on overall costs, especially if they are using a good pool cover. Says Certikin’s Graham Kneale: “Is there such a thing as a perfect energy effi cient pool? No, each pool is individual and the energy requirements will differ for each situation.” But he adds: “Generally the most energy effi cient thing to do is run with the lowest water temperature the customer is happy with, with the air temperature one degree C above this and humidity in the range 60-65%.” Highly-effi cient building materials in the construction of the swimming pool and pool hall, such as good insulation to the hall structure, all assist in reducing the amount of heat loss.


POOL COVER


A pool cover is essential. An insulated pool cover will reduce heat losses from a pool by 60% and is by far the most energy-effi cient device anyone will fi t to any pool. A manual cover and roller will typically pay for itself in less than a year.

fi lter media systems like the Dryden Aqua Daisy or Certikin’s OC-1 will make a dramatic impact on the energy costs. Payback periods of one to two years are easily achievable.


Heat pumps have long taken the role of champions of energy effi ciency for the water leisure market.


The Inverter+ HP allows the heating capacity from 25% to 100% automatically according to pool demand, but most of the time, it only runs by middle and low speed for maximum effi ciency.


TRIED AND TRUSTED “We have seen unprecedented sales of our Inverter Plus heat pump,” reports Peter Turnbull of PPG UK. “Once known as the new kid on the block, this outstanding product now has the benefi t of several seasons of tried and trusted reliability of performance,” he adds. The Inverter+ HP is the fi rst full-inverter pool HP, powered by full-inverter compressor and full inverter fan motor, which adjusts the compressor speed hertz by hertz, and the fan speed revolution by revolution. It matches pool intelligently with continuous and optimal effi ciency.


Market-leading Heatstar produce some of the most energy-


effi cient pool environments in the UK by investing in and adapting the latest energy saving technologies available. These include highly effi cient variable speed fans (that only run
