|Because of the rainy weather I had an opportunity to fabricate necessary pipe work and valves in Mr Henley's new workshop! I was the proud first person to use the work bench.|

I was called out to Sark to resolve a life threatening emergency, no heating. During the week 18 inches of snow had fallen on Sark and lightning storms hit Clos Bourel, an energy project that has been running for 13 years and E-Si's offical R+D centre (renewables Research and Development). At the same time as 2 out of 3 controllers being taken out an airlock had developed leaving the two flats and main house without heating. First available boat I was able to get on was 8am Wed, with no hope of a day return to weather. I stayed on until Friday as the only other boat back was thurs at 11am. All resolved. Next job, hot water and battery upgrades.
The excellent Spirovent dearator! We have and Mitsibushi ASHP and Worcester Bosch condensing oil boiler in parallel the oil boiler for backup in extreme cold weather only each with a Spirovent dearator.

Further air eradication techniques. Watch the bubbles! Flush system with fresh water.
Simple but effective, look for bubbles and dirty water turning clear.
Bypass valve pushes water to heating system and back to purge outlet.
