Off Grid

Our newly renovated premises are entirely ‘off grid’- with no mains electricity, water or gas

Our company started many years before the recent upswing of interest in renewables. Its founding principles were firmly grounded in a belief that by installing energy solutions that did not contribute to global warming or deplete the earth’s finite resources it could make a real difference.  The latest phase in our company’s development is an emphatic demonstration of our commitment to a more sustainable future.

Everything is off grid – from heating and hot water, to borehole water supply  and electricity – is produced on site using renewable technology, and the building has achieved a coveted A rating for Energy Performance. efficient-150x150

Here’s how we did it….

A solar thermal panel provides hot water for the site. Solar thermal is a technology particularly close to the company’s heart, as the installation of a solar thermal system at John and Vivien Turner’s barn conversion provided the inspiration for the founding of their company in 2000. Hot water is provided by a single Genersys 1000-10 panel with a wood pellet boiler providing top-up heat as required

Solar photovoltaic panels supply electricity to a battery bank which in turn supplies electricity for the day-to-day running of the business.

An on-site generator is needed to provide occasional top up to the batteries at times of prolonged electricity usage in the winter months when the available solar energy is at its lowest. The coordination of solar photovoltaic system and generator is handled completely automatically by the Sunny Island combined inverter and charge controller.

WoodpelletboilerHeating is provided by a biomass boiler. Using wood pellets, which are now widely and inexpensively available, the boiler generates hot water for radiators at exactly the same temperatures as an oil or gas boiler, and also provides the required top up for the solar thermal system at times of low solar gain.

True to our environmental philosophy, we aim to encourage the proliferation of wildlife in the locality and have installed nesting boxes for owls and swallows at the new premises.

We also firmly believe in buying locally, and the materials and services required to convert and renovate the new premises have been sourced from local suppliers wherever possible.

“The opening of our new facility is the culmination of years of hard work and the fulfilment of a long held ambition.  The formidable task we set ourselves was to be practically free  from fossil fuels and to generate our energy sustainably on site. There is no ready-made template for doing this, but fortunately with the knowledge we have built up in the company we were able to overcome the significant technical challenges the project presented. Our motivation was not financial – we received no grants for example – but the Renewable Heat Incentive and Feed-in Tariff schemes mean that like any other business we can look forward to an index-linked income stream for our efforts, and are insulated from spiralling energy costs.
We are proud of the team here at Celtic – we remain a family firm and always bring the same passion, expertise and integrity we have shown in developing our new premises to solving our customers’ energy challenges every day.  Please feel free to visit us at our new premises to see renewables in action ! ”
