Great company to deal with. Ordered tank yesterday and could have had it then but left it til today. Enquires sorted in minutes and best price around. Installed within 30 hours and hot water already. Will definitely use this company again and will spread the word to friends and family and anyone else who wants a quality hot water system at the best price around.
