Like most build industries, it is easy to low-ball a quote. Separate the end user from the product (ie- through a developer or builder) and that is the tendency - to bid low. Here’s how it is done: use junk for heat pumps: single speed, no warranty, single-walled exchanger, piston compressor, and the list goes on. shortcuts [...]

Bid and Tender Documents For Geothermal – The First Step
April 30th, 2010 · 1 Comment · developers, geothermal

Frankly, I’m tired of “yelling” in the wind about public or private tenders that have inaccurate loop sizing requirements. Somebody at sometime MUST determine the [...]

So don’t unless you know what you’re getting in to. COP = Energy Output/ Power Input We’ll focus on the load side as that is the easiest [...]

Blackberry…Google…How we use it
January 21st, 2010 · No Comments · geothermal
There are a lot of different ways to store and share information but we’ve found a few useful enough that it warrants sharing. We use Blackberries. Nothing groundbreaking about that. You get phone calls. You get e-mails. You can text back and forth. You can even send site photos to one another. But what we’ve [...]
