I Googled "Central coast hot water" and 1800HOTWTR was at the top of the advertisers, so I called. I wanted to upsize our hot water tank from a 125ltr to a 315ltr. Marcus gave me a quote for a 250ltr & 315ltr. I called back 5 mins later, and asked when he could install. Marcus was able to deliver and install a new Rheem 315ltr that afternoon. He took away the old tank. My mum was very happy to have the larger hot water system installed and very happy with the Service from 1800HOTWTR.
