Are you planning to install a Hot Water System?
Involve your architect or your Sunpower sales representative at the design stage in recommending the size of your system. It is important to consider the size of the property, the number of people using the system as well as the architects.
If you prefer not to have the tank on the roof, you’ll need a pump system. Your architect or contractor must be advised by Sunpower about the appropriate electrical and plumbing specifications to be incorporated into the designs. The roof designs must be able to accommodate the fittings in terms of leaving sufficient clear space around the panels and fixing them to the roof.
Remember to consider your plumbing system, as pipes running in excess of 30 feet to your kitchen or bathrooms will lose heat efficiency.
These are some tips to help you get the best out of your solar hot water system
Why is water pouring off my roof?
The normal function of the T & P Valve is to lift and release excess hot water, thereby relieving
Pressure in the tank which would otherwise cause damage to the tank.
Please contact Sunpower’s service department immediately or their authorized local agent.
Why am I receiving hot water from one tap and not the other?
Could be limescale build up or stuff collecting in tap
Why is my system not producing hot water within an adequate timeframe with good weather
Conditions?
Possible mixing between the hot and cold water pipes due to faulty faucet, or excessive usage.
Why is my immersion heater (booster switch) not producing hot water immediately?
Allow 1hr without using any hot water, this provides the element with sufficient time to heat the
Water in the tank.
How soon will Sunpower visit after I’ve placed a service call?
Allow 1-3 Sunpower business days.
Does Sunpower service other brands?
Yes, Sunpower services ALL Brands.
Why am I receiving only a trickle of water from hot taps?
If a pressure reducing valve is installed on the system, this can be blocked with limescale or rust.
Or blockage of pipes.
