Hi At Better Plumbing we supply and install ITS solar geysers and heat pumps. So if you looking to go green and you got a big family and more than one geyser go for a heat pump as you can connect more than one geyser to a single heat pump with huge saving in the electricity bill. We also do plumbing, maintenance and renovations. Working in the Westrand and Northrand of Jhb. Call for a quote or if you have any plumbing problems. Thanks. Stephen Walstra.
