Solar Thermal Collection

Atlantic Contracting North West Ltd is proud to offer the design and install of your complete solar thermal system.  I can be attached to Biomass, Air Source or standalone install incorporated into your cylinder.  We offer competitive rate and help you choose which application best suites your needs when looking into this technology.

Solar panels attached to a South facing roof preferably (but can be installed on an East/West roof with about a 20% reduction on the South facing). Solar thermal units collect heat from the sun and use it to heat water which is stored in a hot water cylinder. Solar Thermal systems use an antifreeze solution through the solar collector to stop the circulation freezing during our colder periods in the evening when the sun doesn't shine and solar thermal isn't at all efficient. The heated solution during daytime periods flows through a the vacuumed tubes upon the roof then enters the coil within the hot water tank and exchanges this heat with the water that is stored inside. Subsequently, the antifreeze solution returns to the collector for re-heating and the process begins again.

Atlantic follows a guideline of around 20 square feet (2 square meters) of collector area for each of the adult family members. For every additional person we addition 12–14 square feet (1 to 2 square meters).

The Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies among householders, communities and businesses through the provision of financial incentives.

The types of microgeneration systems Atlantic actively install are:

Glazed flat-plate collectors:

These are insulated, weather-proofed boxes that contain a dark absorber plate under one or more glass or plastic (polymer) covers. Unglazed flat-plate collectors - typically used for solar pool heating - have a dark absorber plate, made of metal or polymer, without a cover or enclosure.

Direct circulation systems:

Pumps circulate household water through the collectors and into the home.

Indirect circulation systems:

Probably the most common install is the Indirect Circulation System which pumps a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home.

A solar pool heater (direct circulation) is both popular and practical, it is an open loop system and it's called this because water circulates back into the pool, which is (of course) an open system. The panels can routinely exceed 100°C and can easily heat an indoor or outdoor swimming pool; this is an ideal use and can be a very effective way of reducing the heating and CO² costs associated with swimming pools.

Solar Collector Systems will improve your building energy rating and save you money on your energy bills. In the summer months, the Solar Thermal system can provide almost all of your hot water needs and around 50% for the rest of year. On average, if you install a solar water heater, your water heating bills should drop 50-80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes.

The proper installation of solar water heaters depends on many factors. These factors include solar resource, climate, local building code requirements, and most importantly safety issues before, during and after install. Installation on a residential property will typically take a couple of days. For larger installations on schools/factories or hospitals installs can take up to 2 weeks depending on building size.

Sizing your Solar Collection Heating System basically involves determining the total collector area and the storage volume you'll need to meet 70%-100% of your household, public building or business hot water needs during the summer. Atlantic implements the use of data worksheets to help determine system requirements and collector sizing. The client is always informed about all system size costs and returns.

With a Solar Thermal Collector you are safe in the knowledge that they can provide upto 70% of your yearly hot water needs, which means a reduction on your fuel bills and lower usage also means fewer Greenhouse Gases are released into the atmosphere, vastly lowering your carbon footprint.

If you have any plans to invest in a Solar Thermal Collector but can't decide which one/when to get it done/what it involves/how much it will cost etc. why not contact us and a friendly advisor will try and assist your needs.
