FAQ
 

 

1,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.

2,Does a solar domestic hot water system freeze in the winter?
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.

3,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.

4,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.

5,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 tonnes of greenhouse gas emissions. So, 1 DHW system reduces up to 2.2 tonnes 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.

6,Why should I install a solar water heating system?
Reduce Energy Costs
Whether you are a home owner or a business owner solar energy is free and will have a drastic effect on your energy bills. With the rising cost of energy whether, it is natural gas or electricity, consumers will look for a renewable and free source of energy. Wind and solar energy so far are the easiest to implement.
Reduce Environmental Effects
Reducing greenhouse gasses will slow down global warming as well as air and water pollution. Using solar energy will also reduce the demand for fossil fuels.
Increase Property Value
Property value will increase if a solar hot water system is installed.

7,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.
For example, an average sized pool measures 10ft by 30ft and requires 4 collectors. This would cost $4000. The pay-back period of this investment is between 1 and 2 years.

8,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.
