Solarwise Blanket Systems

The design of the Solarwise fully engineered solar pool heating system will provide significant savings in the running costs of the existing gas heating system. Solarwise solar pool heating will also provide a long term sustainable and reliable method of solar pool heating as we embrace Australian standards, diligent work practises, correct system sizing and design relative to commercial solar pool heating systems.

It does not take a lot of skill to install a solar pool heating system. The real skill is in installing and hydraulically balancing a system that works to maximum efficiency and gives you many years of relatively trouble free enjoyment. Most systems utilize components and installation methods that will have trouble lasting 5 to 10 years, such as rubber based systems, cheap fixings and pumps. No other company fully engineers and balances their solar systems the way we do. Ask us how!

QIS has been in business over 30 years and there is no longer serving Queensland or Australian family owned company within the pool heating industry. The fact is QIS Solarwise will be around to provide post sales and installation service whilst most of our competitors are a small operation or franchise and are unlikely to be capable of sustaining the high level of service QIS Solarwise will guarantee for years to come. All our installation staff are trained and qualified for working at heights with harnesses.

QIS has completed many successful pool heating installations and we can provide details of numerous satisfied customers should you wish to check our previous performance. A handful of recent installations throughout Queensland, New South Wales, Victoria and Western Australia are Clifton Shire Community Pool, Kingaroy Community Pool, Boonah Shire Council, Winton Shire Council, Oakey Army Barracks, Oakey Pool, Toogoolawah Shire Pool, Belyando Shire, Stanthorpe Shire Council, Millmeran Shire Council, Pittsworth Shire Council, Murgon Shire Council, Goomeri Amatuer Swimming Club, Lowood Pool, Laidley Shire, Rosewood Community Pool, Gosford City Council, Shoalhaven City Council (five Aquatic Centres), Goondiwindi Town Pool, Wentworthville Aquatic Centre, Roselands Aquatic Centre and Gosford City Council Pool, Canterbury Aquatic Centre, Corangamite Shire Cpouncil (five Aquatic Centres) and Arena Joondalup Aquatic Centre and Bridgetown Swimming Pool.

A proven track record is far more important than any long guarantee or smooth sales pitch. The combination of a quality product, proper design and installation will be a testimony to your selection long after price is forgotten.

Installation includes

Solarwise high molecular weight PVC Nitrile Black un-punched absorber made to manifolds with Upvc Pn12 pipe, circulating pump, digital solar controller, vacuum relief assemblies, special manometer flow testing and fittings, all pipe work, fittings, system balancing valves, wall work seated in uni-strut clamp and channel or saddles, roof pipe work seated in Galvanised trays for maximum flexibility, break-in to existing filtration system, pipe labeling, pre-installation inspection, supervision, insurances, freight, labour, accommodation and travel expenses.

System Operation

The proposed solar pool heating system is a simultaneous system where filtered water is diverted by a solar boost pump, via a take-off from the return to pool line through the solar collector and back to the pool via the return to pool line. The system involves running the solar pump and the filter at the same time. The solar booster pump is operated by a digital solar controller which measures both pool and roof conditions to maximise the solar pool heating performance by only allowing the system to operate under maximum solar gain conditions, these conditions are when the roof has a temperature difference of six (6) to eight (8) degrees Celcius more than the pool water.

Installation Method

The method of installation will involve breaking in to the return to pool line with stainless steel fittings with flanges “take-offs”, connection to the solar booster pump. The flow and return solar lines are then taken to the selected roofs. The solar absorber material will be adhered to the roof with a high grade silicone. The absorber will be fitted to the Upvc manifolds by way of a compression insert fixing. Each manifold will be seated in and fixed to a galvanised manifold tray for flexibility, roof systems will be fitted with a vacuum relief assembly to assist with drain down and to protect the absorber from collapsing under vacuum. The manifolds will be connected from the circulating pumps via Upvc pipe work to the selected roofs and return back to the return to pool line. The Upvc pipe running from the plant room to the roof and back will be seated in and fixed to a galvanised manifold tray or uni-strut clamp and channel.

The new circulating pump installed by QIS Solarwise will be placed in the plant room, the actual placement area will be determined by consultation with the management of the Aquatic Centre.

ESTIMATED RUNNING COST SAVINGS

These estimates have been evaluated by entering the specific site data provided for the swimming pool into the pool heating load programme designed by Professor Morrison from the University of New South Wales, Sydney. This is the most commonly used programme used by the pool heating industry to evaluate all heat load requirements, running costs, evaporation rates, etc for commercial swimming pools. The results from the heat load programme for the pool is included within this proposal.

The method used was to run the programme with the existing heating and site data to provide an “AS IS” result, the next step used was to enter the same data with the additional Solarwise commercial solar pool heating system. The proposed solar pool heating system will contain 850m2 of solar absorber, this is equal to 100% of the 50mtr pool surface area.

Running Costs

The running costs provided are estimated running costs at approximately 2.25cents per Megajoule and reflect the expected result at the energy costs outlined. The running costs do not include the running cost of circulating pumps and/or other equipment. It is up to the client to confirm the actual energy costs in which case the estimated running costs can be adjusted to the exact energy costs. When this energy cost is provided a reasonably close estimate can be provided based on the data provided. Where we have not inspected the site all performance criteria is subject to a final site inspection as we cannot guarantee the accuracy of the data provided.

ESTIMATED GAS HEATER/SOLAR HEATING RUNNING COSTS

Existing gas heating with solar pool heating system

The estimated savings in running costs are approximately 36.70% or $25,445.00 based on current fuel costs, obviously these savings will increase as fuel costs rise in the future.

REFERANCE DATA

Collector as per AS2369.2

Australian Standard AS3634-1989 for “Solar Heating Systems for Swimming Pools”. This Standard is an invaluable document for discerning buyers considering solar pool heating.

Manufacturers Specifications

Pressure drop (head through PVC pipe)

Pressure drop (head) through solar collector – recommended maximum collector length.

 QIS SOLARWISE STANDARDS

Australian Standards – We embrace all the Solar Australian Standards. Our experience is that few other companies do so.

Guaranteed Performance – We provide genuine collector area (actual square metres of absorber). Some tubular systems are installed covering a certain roof area but have as little as half genuine collector area.

Designed to be trouble free (easily maintained)

All metal to metal surfaces are sealed with hydro-seal or silicon. All fixings and pipes are designed to last, to allow expansion and contraction, all screws or pop rivets are of the inert monel variety.

Fittings at manifolds – This is the heart of a collector. Our experience is that any fitting other than a positive locked fitting will eventually leak. We believe gluing at manifolds or barbs and grommets without locking sleeves will not last.
