Me and the wife went to the home show here in Tucson this past weekend, looking at Solar Heating vendor. Most vendors only have a two or five year warranty. My plan is to get three estimates but what I've researched Heilocol seems to be a good company.
Please review and give advice on what we should be looking for to get the most out of a system. Currently they are setting it up for a 1 to 1 ratio. Roughly 400 sq feet to cover. We have enough of a foot print on our two story home for this coverage. We have great southern exposure. Should we upgrade to the digital control panel?
Had HeliocolWest come out to give an estimate. One of the strong selling points on this system is a 12 year parts and labor on the Heliocol Collectors, There is a two year warranty on the solar controllers, pipes, valves.
Here is our quote and is this decent estimate?
7 HC50's (2x12.5 solar Panels)
HM4000 Auto Control Panel w/ sensors and valving (Heliomatic)
2" schedule 40 PVE plumbing lines - trenched / painted
Shut-off, drain, check & V.R. Valves
Price Quote: $5,125
Homeshow Discount: -$500 (priced increased to show a savings??)
Cash Discount: $300
Final Price $4,325
Addl upgrades if wanted:
HC40's - Installed $400 each
Suntouch Digital Control $300 (Pentair)
