Questions & Answers
How long does the installation take?
It can take 1 to 2 days to install a domestic hot water system for a home or cottage. A pool installation would take 3 to 4 days depending on the type of installation (ground or roof install).
How big are the collectors/will my roof withstand their weight?
A collector measures 6 feet wide and 6 feet long and weighs 170 pounds. It is mounted on the roof flat against the shingles with 4 legs which attach to the trusses. The weight of the collector is well within the Ontario building code.
How will the collector look on top of my house?
The collector is mounted flush with the slope of your roof. This is called a "flush mount". In some cases it is difficult to see the collector on top of the house.
Would a roof installation cause any leak?
The solar collectors are professionally installed on your roof ensuring no leakage occurs. An installation warranty of 2 years is included. However, if your roof is in poor condition we would recommend a ground installation if possible.
What if I am planning to replace my roof?
It is recommended that you replace your roof before having a solar collector installed. If you are replacing your roof after your collector has been installed be sure to call a professional to detach the collector before the roofers remove the shingles and replace it after they have completed their job.
Where solar collectors should be installed?
The collector should be installed in an un-shaded area. We would access the area prior to installing the collector and determine the best location. Keep in mind that the location should be clear of any shade caused by neighboring buildings or trees. In the winter the shadows are longer due to the low position of the sun. The collector should face anywhere in between south-west and south-east in order to absorb the maximum amount of sunlight.
Can I install a system myself?
Yes, the solar collectors can be installed with ease. An instruction manual can be provided with each system. It is recommended that a plumber or contractor oversee the installation to make sure that all building codes are abided by.
How does a solar domestic hot water system work?
A solar domestic hot water system works in two phases. First, solar energy is captured and converted into heat. This is done by the solar collector. Thermal fluid, which resists freezing, is pumped into the collector where it absorbs the heat. The second phase occurs in the heat exchanger tank where the thermal fluid exchanges its heat to the water in the tank. Thus, the water in the tank is heated and sent to the current heating system.
Does a solar domestic hot water system freeze in the winter?
In order to prevent any freezing a mixture of glycol and water is pump through the heat exchanger coil and the pipes leading to and from the solar collector. The tubes are very strong and do not break with ease. If a tube were to accidentally break due to extreme circumstances, replacing one is quick and easy. The tubes are inexpensive and are readily available.
Does a solar system produce hot water on a cloudy/overcast day?
Yes, the solar system will produce hot water however it will require the assistance of the current electric or natural gas heating system to reach the desired set temperature.
Can a solar system work with my existing hot water system?
Yes, our solar system is most commonly installed in homes with current hot water systems. Combining the two systems is very easy and is the recommended method of installation.
Is there enough sunshine in Canada to heat water throughout the year?
Yes, there is plenty of sunshine in Canada for an evacuated tube solar collector. Unlike other solar collectors the evacuated tube absorbs over 92% of the UV rays.
Can it withstand elemental forces such as high winds, hail and snow?
Yes, the collectors are designed to withstand high wind speeds and heavy snow fall. The glass tubes can withstand hail stones up to 25mm (1in) in diameter.
What about environmental issues?
A solar domestic hot water system reduces up to 1000 cubic meters of natural gas a year for an average household. This is equivalent to 2.2 tons of greenhouse gas emissions. So, 1 DHW system reduces up to 2.2 tons of greenhouse gas emissions a year for an average household. The system can also be used in restaurants, malls, cottages and office buildings where it can reduce even more greenhouse gas emissions.
How much money can I save?
With 1 domestic hot water system an average home (4-5 people) can save up to $600 a year on their natural gas bill (given a rate of $0.50/cubic meter). If a household uses an electric water heater the savings can be higher. A solar pool heating system can save up to $1000 in pool heating costs per season. The money saved can go towards throwing more pool parties and spending more time outdoors during the summer. Not to mention the fact that a solar pool heating system extends your pool season by 2 months. Businesses can save even more on their energy bills depending on their hot water demands. With the rising cost of natural gas and electricity the savings will keep getting better.
Why should I install a solar water heating system?
How much does a solar pool heating system cost?
The cost of an installed solar pool heating system depends on the size of the pool and where the collectors are to be installed. For example, if the collectors must be installed on a roof then the installation would cost more than if it were to be installed on the ground. The number of collectors depends on the size of the pool. The more collectors are required the higher the cost of the system.
What if I am planning to renovate?
It is a good idea to let us know if you are in the process off, or are planning to renovate. There are ways to save money on the installation if you will be having a contractor do the renovations for you. We also offer free consultations with the contractor to assure the best and most efficient installation is provided.
