Hot Water Evacuated Solar Tubes

The latest Swiss manufactured evacuated solar tubes.

These new evacuated tubes are amongst the most efficient solar collectors available. These domestic solar tubes for water heating work all year round, contributing to your household energy needs.

" Did you know, solar tubes work all year
round, even in the UK "

The latest NEW twin-glazed thermos flask solar tubes, recovers the heat 'lost' by other systems, creating the best performing high efficiency solar.

Schematic - An evacuated tubes system with a SUPER EFFICIENT hot water tank,
installed and benefiting your home for the next 25 -30 years.

The benefits of solar tubes

A solar panels installations is like converting a car into a hybrid running on LPG. After the initial investment, your car or in this case your home will run efficiently and cheaply for the 30 years.

What sets us apart, is we modernise and bring your heating system up to modern 'building regulation' standards. Installing solar tubes is only a smallpart of that. From March to October you may not need to use your boiler and in winter it will dramatically reduce the need for your boiler to fire up throughout the day.

Quality & performance unrivalled

Our decision to showcase and install Sun Systems solar tubes is based on aesthetics, quality components, reliability and unrivalled performance.

No planning permission needed in most cases.

Sun Systems evacuated tubes

We install Swiss made Sun Systems evacuated solar tubes and German made Schuco flat plate solar hot water panels. Solar4U also installs Schuco PV (otherwise known as photovoltaic) panels which generate electricity.

The Sun Systems solar collector is Solarkeymark accredited along with a range of other international quality certifications.

How this supersedes old style solar?

1. This solar technology includes the patented Low E glass. This uses a special low iron glass formula which has reduced the reflective properties and increases the absorbtion.

2. Because the glass surface is not flat. It has 360 deg absorbtion ability, which give better performance than all other flat solar panel technologies, giving a more even output throughout the day.

3. Each solar tubes has twin-skin vacuum filled glazing for better heat retention. Just like a thermos flask, once the heat is in it becomes trapped.

At present this solar technology is sold in the following countries:

Australia, USA, Canada, Middle East, UK, Ireland, Italy, France, Sweden, Bulgaria, Greece, Portugal, Slovenia, Cyprus, Hungary, Spain, Singapore and South Africa.

The Mercedes of solar panel technology, that
lasts longer than your mortgage

How does it work?

1. Evacuated solar tubes heat up due to solar energy.

2. The solar controller controls a variable speed pump.

3. The circulation pump circulates a special fluid through the hot solar collector and trough a heat exchanger in your hot water cylinder, the heat is transferred to the cooler water in your cylinder.

4. This is then delivered to the cylinder/tank.

5. System shuts down automatically when not in use, or when the collector temperature is lower than the cylinder.

6. Your solar collector will store up heat even on cloudy days, so when the controller detects useable heat it will start up again.

7. You now have lots of free hot water to use day or night.

Getting installed

1. If you can face the tubes roughly towards the sun. South, southwest or southeast roofs are ideal. Even east or west roofs usually offer 85% of the performance.

2. If your hot water cylinder is twin coiled. It does not matter if you don't as we can install a solar compatible and more efficient tank as part of your installation.

3. Listed buildings, conservation area homes, national parks may need consent. Please consult with your local planning officer.

The Sun Systems evacuated tubes system is Solar Keymark Accredited and EN12975-1: 2006 approved, also LCBP listed product.

Combi boilers

Combi boilers are possible but please bear in mind, that we will need to re-install a hot water tank. Most homes with combi's will not have the space to install a domestic sized hot water tank. If you can re-install a hot water tank, then yes an installation may be possible.

Frequently asked questions

How exactly do solar panels work?

The science bit - When solar radiation or solar energy hits an object, you me or a solar panel, the short-wave radiation is converted to long-wave radiation and this process creates heat.

Why is it important to update my hot water tank?

Very simply, old copper hot water tanks run very inefficiently when new, but after many years of use, limescale will reduce it even further. When installing solar tubes, it is important to install a modern more efficient tank to get the most out of your solar gain.

"Adding a solar to an old tank would be like converting your car
to LPG and running it on semi flat tyres"

How much will my system cost?

Contact us and our solar surveyors will provide you with a tailored quotation. Please go to our price and suitability page >>

How long will it take you to install my system?

Normally only a few hours in most cases.

How long will I be without water during installation?

Only 4 - 5 hours.

Will you need to change my hot-water cylinder?

No if your tank is solar compatibe or has a twin coil unused. In most cases though it is recommended that you upgrade your hot water tank when installing solar panels or solar tubes to allow the system to work at its full capacity.

How much CO2 will my system save?

Around half a tonne each year. This is dependant on how much hot water you use and how you heat your water at present.

Do we get enough sun in the UK to really make a difference?

Yes. Our evacuated tubes are designed for the UK climate; they use a thermos flask principle, which allows the inside of the solar tubes to get very hot regardless of the air temperature.

What water temperatures can I expect?

A good proportion of the year your water will be heated to above 60° C.

Is there a danger that the water could get too hot?

No. The system is designed to never reach above 85°.

What makes your collector better than your competitors'?

We believe our Sun Systems solar tubes and flat panels are the best because they have been shown to out perform any of our competitors products.

Does my roof have to face directly south?

South is the optimum and southeast and southwest are fine. Check your homes with our suitability survey >>

Do you send salesmen round to my house?

Many solar companies claim to send surveyors to your home, but really they are only salesmen. We properly survey your home and provide you with a tailored quotation based on your individual homes specifications.

This allows us to sell you a quality system at a reasonable price.

A word about quality

There are some companies who are importing and selling poor quality Chinese systems in the UK. Solar4U has been approached by these companies, but we refuse to sell sub-standard systems to our customers.

As with anything in life you get what you pay for, so a cheap option will undoubtedly will be a false economy were longevity and performance is concerned.

Solar4U offers a 'no quibble' guarantee on quality.
