I bought a house with this geyser installed before my arrival, although I inherited it and it seems to work well, which I cannot prove due to to the non existent aftersales process, the company absolutely ignores just making a user manual available to me, so now I am stuck, I have written to them on many occasions, and their response is that they have no record of the installation, so they cannot provide info, since then, they have ignored all my requests, just for a user manual, I would steer clear, because at R28000.00 I doubt that they will cover guarantees when they cannot even supply a user manual to an existing system.
