Thought my website: www.heatmyhome.co.uk may come in handy for you DIY
solar enthusiasts.

Simply put, 'direct' solar tubes are the most efficient solar
technology available. This is based on a 2001 study of all solar
technologies by the Department of Trade and Industry. (Now Dept of
Business).

Since then solar tubes have evolved further, and now we are proud to
showcase the latest in ‘direct’ heat solar tubes, which have improved
solar efficiency even further, using only the highest quality
components available in the solar industry. This gives the advantage
of better performance and peace of mind but with no heat exchange
required, this can free up your twin coil (when applicable) for other
applications such as under floor heating/bio mass stoves etc.

1. If you have a traditional ‘gravity feed’ system, with a southerly
facing roof space, then you home is ideal.
2. If you have a ‘vented’ thermal store with twin/solar coil, then
your home is suitable too.
3. If you have a Combi Boiler, then you will need to replace this at
the end of it’s life for a condensing boiler with ‘vented’ tank.
4. If you have a ‘high pressure’ system with gauges, then you will
need to replace this with a ‘vented’ tank.
