I've just had a Sanden heat pump hot water system installed by pure electric. The whole experience has been very good from initial quote right through to the installation. It's my second Sanden (had one installed at previous house). I used a different installer for the first one. This experience was miles better! I was given heaps of info about the product (which for me I didn't need, but would be great for those unfamiliar with the Sanden) before and after I accepted the quote. On the day, the plumber was spot on time, polite, neat and did a very good job with good attention to detail, which is vital for a high precision system like Sanden. There was one extra on top of the original quoted price, but this was a necessary extra electical circuit that needed to be run and this was also flagged as a possible extra cost in the original quote. The plumber checked with me and got my go ahead before doing this small bit of necessary extra work. Very very happy and highly recommend this company!!
