Our Technical Services Capability
As a company we have 17 years of working in the residential construction industry. We have professionals who have worked in a variety of industries including residential, but including the army and merchant navy, giving us unparalleled experience and technical insight. The business is strongly technically driven, almost to the point of being geeky about it. Yet we have to translate highly technical and technological concepts to be appreciated and understood by the homeowner. This is a major challenge. On these pages we home to provide greater insight to the workings of advanced renewable energy concepts, starting with the fundamental basics to systems that power our modern global society.
We are at your service and provide customer care for electrical, heating and water systems around the home. We service oil boilers, heat pumps, solar systems, electrical and hydronics systems. Because we've seen a lot of things go wrong, we know how to make it right! Because we have tried every type of solar system, heat pump and boiler, we know which manufacturers, which equipment works and which does not.
We design, provide schematics, quality control, pre-commission and commission all our systems and installations in-house. By keeping all our services in-house we have control over the quality of install, service and maintenance. See About Tech for more information.
Our Tech Talk pages are meant to be educational, entertaining, useful and designed to promote discussion, inspire you and create 'different thinking'. Here at E-Si we pride ourselves in thinking differently. Its a way of life for us.
