    Is it fair to say that, generally speaking, the lambda's main role is fuel-conservation? Longer burns, presumably?

    I would add that it makes it load it and forget it. The Lambda sensor drives the dampers so it always burns as well as it can eliminating the need to go play with it.

    modulation will extend burns, within reason. the main reason for a lambda control is to make sure you have enough secondary air available during the initial flare off of the gasses from your wood load. especially if you're using small and or super dry or sappy wood like pine. it cuts emissions mostly, and gives you a couple percent additional efficiency over fixed settings, assuming you have fiddled with them enough to get them set well in the first place.

    can someone help - I have a vigas 25 - had a burst pipe and shed was flooded - now the boiler when I try to turn on by plugging in socket just trips by electrics - I don't know what to do? Any ideas? Does it just need to dry out? The pipe burst shot water all over the boiler.thanks

    Sorry to hear this. The cold weather you have seen has caused lots of problems. For certain before turning on the boiler you need to let everything fully dry out. Can you put an electric heater in the shed and maybe a fan blowing on the boiler pump motors?

    Also, with the power to the shed off, open the top control box cover and the fan cover to make sure there isn't trapped water inside of them.

    Thanks I can put a heater in not a problem - the sockets are fine and power boxes all fine as tried different items on them - just the vigas power plug trips the electrics - it was switched on before the burst pipe but not running - as we got caught out so quick our water into the shed froze - didn't think water inside the shed would freeze - but we went to -10

    Thanks it is now staying on without shorting.

    However I noticed also I have an ESBE LTC100 valve system the pump has cracked which was a Wilo RS25/4 - does anyone know what pump I can use to replace it as RS25/4 seems to be discontinued - Thanks Manjit
