This Rinnai solar hot water system needed some repairs. The system was a flat panel split system with a gas instantenous back up hot water unit. These are the most efficient systems when it comes to solar.
Our client advised us he noticed the gas backup was running more then normal. After close inspection of the unit we found the pump had seized and the client was not getting any energy from the flat solar panels into the tank the pump was replaced and system tested all fine.
