Hi Nathan,
I'd probably take one.
Couple of points PF would be mad if he followed through.These heaters must be sold as what they are, not as possible WFP diy projects.
Your price point competition is not the L5, they are a toy.Your competition is rinnai and marco CE marked heaters, which are more expensive than the price you mention.
I'd like to know what concept use for the £2,800 package.I think it must be the infinity with a powered flue.I'd also like to know what their gas set up is.I understood that they did a sort of lpg conversion and put the tank where the spare wheel goes, but if this was true they'd use it as a USP- and they don't.
A pump board (pump and varistream) is about £200, i've got four but only use two, and it's probably the same for others who don't like down time, so i don't see a couple of heaters as a problem if they are the tool for the job.
So thumbs up from me.Excellent idea.
