Generally happy but we may look at other brands when we need to replace this one on advice of our plumber.He seems to think that the price of new units outstrips Sola-Harts reputation
Had a 300l system installed around 12 years now. Last year had leaking valves replaced- cost $600ish. Our system faces dead north and with only 2 users runs far too hot in summer so we cover the RHS collector with shade cloth in warm months(Perth,W.A.).One of the co-developers of the system installed it and told us to do this(prolongs system life he added) ,although a S/H tech seemed a bit evasive on this subject even when pushed about it???
They are a costly item ,but we have recovered costs I suppose.
I originally wrote the earlier review (Feb. 09))having thought the tank had rusted from the outside in due to salt spray gaining access through the electrical wiring cover. This is how it appeared from the water leaking out when the tank was in-stu on the roof. However, once on the ground I removed the inspection plate as well as the sacrificial anode. The sacrificial anode showed negligible signs of corrosion (about 5-8%)after 8 years (reflects quality of local water supply)having originally been replaced (obviously uneccessarily)4 years after...purchase of the system in September 1997. On close inspection of the inside of the steel tank there appears to be a fist size area of rust and corrosion on the end of the tank, just below where the sacrificial anode entry point is. This is where the tank has leaked and it is highly unlikely to have been caused from the outside-in (as originally thought) due to the foam insulation around the outside of the tank in this area. Furthermore, there was a lot of sludge sitting on the bottom of the tank which I attribute to the corrosion of the sacrificial anodes. This is another minus in my opinion for this type of system. I have since replaced the tank with a stainless steel tank from another manufacturer. No inspections of the sacrificial anodes to pay for in future, no replacement sacrificial anodes. It will be interesting to see what life I get out of this new tank. Like other solar products it uses renewable energy. The tank didn't last the generally advertised 25 to 30 years. Mine lasted 11 years. The solar collectors however still appear okay.
We have been using Solahart 300L system for the last 8 years. In that time we only had one problem with one of the valves on the roof (valve cost approx $100 and it took only a few minutes to replace). The electric booster is switched off all the time and only get switched on when we have long periods of rain. This year so far the cost of electricity for the booster (separate meter and cheaper tariff) was under $10. But I have to admit we are well situated: north of Brisbane and the system is directly facing the north. I cannot say if it paid for it self yet, as it was part of our new house.
Saves energy and money, very hot water
Questions & Answers
how much is it to buy a heating booster element for a 300LJ system?
i assume they are about 3.6kW?
I have owned my solahart l series for 4 1/2 years and will require service shortly.
The question is what parts are included free in the $350 SERVICE cost. Eg cathode , tempering valve, filters any oyher valves
