Hi ROB G, rbrett & sewad
Thanks for the postings - I apologise for the delay in responding.
I'll come back to you on projected price and availibility very shortly.
The boiler/burner combination that will be offered is currently undergoing proving tests and I hope to be able to post a picture of it on its testbed shortly.
As we are very concerned about safety issues, the boiler will only be offered in its complete form - no kits or drawings.
More shortly.
Stuart
