STAY AWAY AT ALL COST Had a unit installed never worked properly never got a certificate turns out after contacting the plumbing board he is no longer licensed. Dodgy installer used the wrong copper pipe
another install caught fire that he then returned and pulled out the unit that he said he was going to install else where so someone out there has a second hand T315 that has had a fire in it . [redacted defamatory comment]

Approximate cost: $2000
