Sorry guys but in 2010 Part G of the Building Regs changed so that it covers all hot water systems both vented & unvented, stored & instantaneous, to comply with the letter of the Law you now need to hold the Part G to install & commission any hot water system.
The only concession which now applies to the Litre's is that if it is below the 15 & soloing as it is installed with all the manufacturers required safety devices there is no requirement to notify Building Control.
