Atmos Boilers are SEI Grant Approved
Just to note that SEI do approve the Atmos for the grant scheme. Check this out for yourself on their site at www.sei.ie. These boiler are ISO9001 and ISO14001 approved. There are spare parts readily available and the company is fairly widly recognised and reputable.
Have a look at the Atmos site: www.atmos.cz
Also the Polish company I listed with the great prices for Atmos is a wholesale company, not retail - but I am sure if anyone was buying several units at a time they would be happy to do business.
