Just got a new cabin pak (external in an enclosure) warmflow 90-120 model
http://www.warmflowboilers.co.uk/pages/external.htm

the boiler manufacture recommends that frost stat is fitted but
dont specify a particular model.

I dont want something that will run the boiler continuously when the temp
gets below 3C say or the boiler will run all winter (as it doesnt heat up
the outside) so im guessing its possible to get some sort of frost pipe
stat which detects the pipes are warm enough ?

Anyone have any experience of this and can recommend something... have
already contacted warmflow once but they were rather vague....
