James Laing of the Church of Scotland in Israel writes:
“Another carbon-saving measure we have taken is to instal solar water heaters on the roof of St Andrew's Guesthouse in June 2010, replacing old oil-fired boilers (which were not only inefficient but also dangerous and due for replacement!) The heaters are topped up by a natural gas-fired boiler, which is rarely required. In the last 12 months since installation this saved NIS 90,000 (GB£15,430) in financial terms, or about 11,870 litres of fuel (diesel oil which is NIS 7.58 per litre).”
