can the cover on the tank be replaced if hail damage exists

when I had a solar hot water unit it had the relief valve connected to the spouting this let hot water return to tanks but I also fitted a blind and when was over 30 I would block off some of the collectors but it is also possible to have the tank fitted with a control to stop this solar hart can supply

This happened to our solar hot water system shortly after it had been installed. We had to call a plumber to fix the problem. We would like to replace our system but would not go for solar again. In winter we have to run system on day rate to have enough hot water to last for the day.

Called plumber. It was the valve. Workmanship plus parts and get $255. Fixed but will have a high water bill. I love my solar. Had it 4 years. Water always hot. Have 5 panels and was getting credit but last couple of bills had to pay but still a lot less than b4 solar

your thermostat may not be working ask a electricion to check it.

I have an Aldi water pump connected to my Rain-water tank, is maintains constant output pressure, two pressure sensors control the function of the pump, one measures output pressure and is in the outlet reservoir of the pump, the other measures the input pressure just after the input filter and turns the system off if the filter is blocked. Check your input filter, clean it regularly depending on the quality of the water you receive.

Hi there, I live in an area of fairly intense summer sunshine and have had similar problems with my solahart. I think what happens is you turn on the tap, the pressure in the tank drops slightly and this allows it to boil. It is not a particularly good situation as the pressure fluctuations and heat could possibly stress the system ultimately causing leaks. It can also lead to hydrogen build up under some circumstances due to decomposition of the anode. You need to cool it down. A cheap low tech solution is to cover the panels partially or completely with shade cloth during the hottest time of year. A bit of experimentation should enable you to find the correct amount of shading needed. Jim

Thank you Jim for your suggestion. We think this is what will need to happen. Just hope Solahart foot the bill to add retractable blinds
to the unit..should this be the only solution.

I Don't know.

It's a safety feature of the system, if there is a string of hot days or days of little hot water use the water temperature in the tank can get very high, when that happens the safety valve opens and dumps some water to reduce the temperature and pressure. It's normal, but it should be a rare event.

I have had the same problem and this is what I did.
First - Make sure you have a vacuum breaker unit fitted to the Solarhart system, My old Solarhart did have a vacuum breaker. Your input supply to the hot water system should have a tap - Turn off this tap. Then I open the hot water tap in the bathroom to the bath-tub which has its drain plugged, so you can reuse this water. As the pressure drops in the system the flow slows down to a trickle. The Bath tap is also one of the lowest taps in the house, so water drains there first. If you find this is the case in your home, then you can replace the other hot water taps without too much water draining out of them. Make sure you do have a vacuum breaker - its important, especially if your system is a newer one, my Solarhart was a 1983 model, now replaced. The tank drains but not fully just about one-third of a bathtub in my case. Now I can drain my hot water system into the gutter which ends up in the rain-water tank - no wasted water.

Sorry Mark but i can't answer that type of question.
I have no idea.

Thanks for responding Missy! I found the part by contacting a Solahart rep in Portugal, who contacted another in South Africa, who put me in touch with apparently the last supplier in the USA (San Diego, California). The San Diego supplier turned out to be a spectacular help (found the part and sent it to me straight away).

Best Wishes,
Mark

you should be able to use a 1 inch male plug from a plumbing supply to fit the unit
