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 [...]

Busy start to the spring, so I’ve fallen behind a bit on some detailed posts I have in mind. I’ll default to pictures. Thanks to Charlie’s Backhoe for the extra care and attention that went in to this particular job.

Catching up in 2010

It has actually been long enough that I’m getting people telling me I need to update the blog. I have a tonne of ideas I’ve been trying to get down, but in the quest for completion, they never leave the draft stages. I will just dump what would likely have been 5 0r 6 blog [...]

Electrofusion
August 24th, 2009 · 1 Comment · geothermal, installation
A bit of a dilemma with a recent header construction. This is one end of a vertical closed loop installation. The client has an existing, but unused well, that we have inserted two U-tubes in to take advantage of this fact. Prior to finishing the fusion of the header, the majority of our header was [...]

Embarrassing System Startup
September 10th, 2008 · 1 Comment · geothermal, installation
99% Done. At least that’s what I thought. The system had been running over night. I had fixed some of the leaks on the client’s existing plumbing from an old boiler radiant system. Replaced a few plumbing fittings. I had also just completed the system diagnositics: taking pressure, temperature, flow readings to ensure the system [...]

Trench Safety …or…How to Not Be Buried
August 17th, 2008 · No Comments · installation
We lay pipe in trenches all the time. Anything involving working in trenches greater than 4′ deep would involve shoring or other safety measures. This would make our work very expensive and very slow, so we do the next best thing. We pull the pipe out along the top of the trench, drop it in, [...]

Bucket Pump for Geothermal Loop Pressurizing
May 15th, 2008 · 2 Comments · installation
The purge cart is over-powered and there isn’t necessarily an available source of pressurized water on some construction sites, so here’s a bucket pump we had constructed. This is a nice portable method to pressurizing a closed loop installation. The end connection allows us to pressurize through the P/T plugs on the system. A couple [...]

Antifreeze Colouring
May 15th, 2008 · 1 Comment · installation, maintenance
All our installations are either methanol or propylene glycol for the choice of antifreeze. CSA requires the equipment to be labelled with the type and volume/percent of antifreeze. On top of that, we add a little food dye to the antifreeze to help differentiate what we’ve installed: Nothing = water Red/pink = propylene glycol [...]

A Bit of Fun
February 22nd, 2008 · No Comments · geothermal, installation
I warned Craig I was going to post this on the blog…he’s showcasing our latest installation. Thanks go out to our ducting guys (Kamloops Sheet Metal) and the plumbers for making this all work well together. That is the purge cart still hooked up to the one system as we were introducing antifreeze in to [...]
