Oil service "Going Green"

Read more...This story was submitted to the site yesterday, Dennis the writer is interested in raising awareness of solar ventilation products as an alternative to gas and oil-based ones. He had an interesting encounter with a local firm who specialise in servicing oil boilers. In short, they are experiencing a decline in demand for their services as customers are becoming more interested in "Greener" technology. Read on for Dennis' first Blog installment. 

Oil servicing firm re-brands itself "Green"

These guys - www.greenenergyshropshire.co.uk - have built a business from servicing oil and gas boilers and are Oftec registered (oil firing technical association), they have worked out that the demand for oil fired central heating systems have begun to decline, so they are beginning to turn their business green. Hence my story of OFTEC registered engineers becoming a good source of solar solutions for both air and water.

The Story

My oil central heating boiler was due a service recently, and I had a real surprise when I called the company that had left their service sticker on the boiler cabinet. I expected the obligatory service engineer to turn up and do their stuff. The engineer was a pretty smart type, a real techie. When the service was done I was suddenly led into a conversation about the cost of oil and the potential for all carbon based heating energy to rise in price. Once we had agreed that heating oil was becoming horribly expensive the conversation was directed to all things solar and what can be done about it.

This particular company had rebranded itself GreenEnergy (Shropshire), and their intention moving forward is to help their traditional base of customers with oil and gas fired systems add solar technology to help reduce fuel bills. My boiler technician was a full of sensible information as to how to save money. They had infra red heating technology, ground source heat pumps, really innovative hybrid solar heating systems, even a range of wood burners.

Why? I asked are you doing this. The answer was simple but fascinating: the sales of gas and oil boilers are already beginning to decline. For OFTEC members the market is already shrinking.

"Hydrocarbon based heating systems are seen as a bad future investment."

I liked the honesty of this company; it seemed to be all a about green evolution as opposed to  revolution. My engineer from GreenEnergy (Shropshire) had a clear view on how a householder should begin the green evolution.

- Do not throw the baby out with the bath water, your central heating system works and has value.

- Most people cannot move to some expensive technology, most people want to start modestly and develop a strategy for saving money. So I asked the question. “If you were me and wanted to spend £500 improving the heating efficiency of my home what would you do?” 

The answer is solar ventilation, so I am off to Chirbury Shropshire to visit their brand new show room to find out all about products like SolarVenti.

In the meantime my OFTEC engineer recommended I visit Solarairtech.com to catch up on the solar chat and find out more about solar ventilation, and issues such as humidity damp mould and all the stuff that says your home and heating system is not up to scratch. Thanks OFTEC and Solarairtech. I am learning some sensibly priced green lessons!

Must See: Quick explanation of how a Solar Ventilator works

Obviously, we're big fans of solar ventilators here at Solarairtech.com. However, explaining the science and how the actual things actually work is sometimes a bit of an up hill struggle. 

As we've maintained, solar ventilators have a hell of a lot of benefits - improved air quality, heating capabilities, returns on investment and reductions in both your carbon footprint and energy bills. 

Nevertheless, a picture - or video in this context - speaks louder than words. Check out the informative video below for an overview of the technology and why people love it so much. 

 

 

Solar ventilation in Scandinavia - why it's so popular

Been up in Scandinavia visiting family and they had a Solar Ventilator. They are becoming very popular there; it is the new sort of green device up in Northern latitudes. Apparently Solar Ventilation is catching on because of the level of insulation used in producing high levels of energy efficiency in Scandinavian homes. The typical Danish and Swedish home is very prone to fill up with condensation quite simply because they are so sealed up.
No one opens a window in winter as energy is too expensive to let it drift outside into the cold. What I did not get was that solar ventilators are not about only hot air and the heating effect but something much more subtle. As my friend explained the cold in Scandinavia is much more bearable than in Britain because it is a “dry Cold”, the air has no humidity, and it is humidity that saps the heat out of you body. Well a house is the same, if your house is full of damp and condensation it takes longer to warm up, plus it fills with the living space with other environmental changes that are not so good for your health.
The Swedes love Solar Ventilation for another reason that is not just the free air flow driven by solar power but also because it provides a high level of energy input and saving. Say your solar ventilator provides 100  cubic metres of air every functioning hour at 26 degrees centigrade, that represents useful energy, but what needs to be considered is if you put that volume of air through you home on a typical British winters day but not through a Solar Ventilator it would be at 5 degrees Centigrade thus making the home colder. So the Swedes would argue the energy input is that provided by the Solar Ventilator plus the energy not lost by pumping cold air into your home. So I can see that Solar Ventilation is a pretty clever particularly when you dont have to heat up all that condensation as well.

So I can see that Solar Ventilation is pretty clever, particularly when you don't have to heat up all that condensation as well.
