Talk to Precision heating, they are the Irish suppliers of everything Viessmann http://www.precisionheating.ie/ , I have worked a lot on Viessmann gas boilers and find them very well put together and reliable as you have heard but anything from them does tend to be expensive, so the funky oil boiler wouldn't be cheap money i would bet, Gary.( no connection with Viessman or Precision)Was looking for an extra efficient oil boiler and came accross viessmann.But I can't seem to find much info on Irish or UK websites,although I did read that some were installed in the UK.Not sure if this is because they are probably way more expensive than the grant/firebird condensing oil boilers or maybe because they are probably much more complicated animals.They certainly sound the part and I have even seen claims of 100%+ efficiency (how ever that is possible) on their triple pass oil boilers.I know they are well regarded by many for their gas boilers,so would have thought that their oil fired boilers would have made some inroads here too.
Does anyone know anything about their oil boilers?

Hi all, couple of questions;
Putting in a condensing oil boiler in detached garage. There will be in the region of 17-18m of pipework between boiler and house.
Plumber suggests puting pipework in 6" ducting buried underground with 1" armoflex lagging around pipes themselves.
Architect reckons a highly efficient pre-insulated underground pipe is the way to go but at €40-50 per metre it will be fairly costly.
Any suggestions?
Also if its done by method 1, would filling the remainder of the duct with other insulation like rockwool be any addition?
Grant do a 98% HE model, which is damn impressive.
Thanks for the replys folks - think I'm going to go with the Grant.
Riverking - I'm thinking of doing something similar - run lagged water pipes through a sewer pipe, drill some holes and fill with expanable foam. Going to try and have it a deep as possible also. That 'should' keep the temperature loss to a minimum on a budget.
Anyone else out there have any thoughts on this method?
i think davy may be referring to the grant vortex range which claims 98%
efficiency as opposed to the grant euroflame range which claims 95%. there's a few hundred in the difference price wise
spend money on the preinsulated pipe now, it will save you money in the future. The problem with your method is that water will enter insulation sleeve because of our wet seasons and you will waste energy heating this water.
€75 differance from my supplier.
So the HE model you spoke off,is the vortex one?
Davy Jones,
What in your opinion is the best method to run pipework between the house
and the garage where the boiler is located ?
My Plumber is also suggesting to put 1" armoflex lagging around pipework in 4" ducting buried underground. What is the best method to prevent water entering the pipework ?

Interesting discussion. I have just bought a house with an ACV Combi boiler in the garage (about 20 feet from house). House and boiler are only about 4 years old but I have been told that underground pipes from garage to house (UFH) were not insulated properly and that heating is very expensive as a result. Any suggestions on what the best way for fix the problem might be? Would it be maybe possible to spray expanding insulation foam down into the underground pipe somehow?
All advice appreciated!
Thanks
