We recently needed to urgently replace a direct gas booster on our solar hot water system due to unacceptable performance of our gas supplier (bottled gas) leaving us with no hot water for days. Pure Electric responded quickly to an initial email and was able to design a system to incorporate the functional part of our solar hot water system with a new Sanden heat pump system so we get the best of our solar investment and retain a significant solar input to our hot water through the year, without the unreliable gas component. All the other companies we approached wanted to simply dispose of thousands of dollars worth of serviceable equipment. The new system was installed within 24 hours of our initial contact with them. I can thoroughly recommend Pure Electric, particularly if you are looking for a solution that is not just "out of the box"
