The discussion about this boiler on another thread intrigued me.
I started another thread to ask some questions without continuing the Hi-Jack.
Is it the same FT heat exchanger that was introduced by triangle tube?
I know Triangle Tube had trouble with the efficiency when they tried to turn it down that low, I wonder what HTP is doing different? I can't help being a bit paranoid after the Volkswagen ordeal.
Both Triangle Tube and Lochinvar are routinely installed at high altitudes. They both have had issues with the units making a trombone sound at low fire (4/1 and 5/1). With a 10/1 turndown, how is the noise?
Has anyone installed the HTP at altitude?
The manual has several warnings about minimum flow rates yet never list what those rate are at low fire. The math works fine for me with 1 GPM on the 80k/btu model at low fire, it would end up with a delta t of (8,000 x .92) / 500 = 14.72 degrees. I just don't see it in the manual. The controller looks like it is OK with delta's up to 55 degrees.
I wonder at what point turbulent/laminar flow becomes an issue?
The boiler only has an on/off circ controller. I have only browsed the manual but have not seen a part about the delta t circ options.
I am certainly not doubting the statements some have made about this product, just wondering if they have info not represented in the manual.
This would be a perfect fit for a job I am looking at which is at 9,200 ft above sea level. I am just reluctant given it is relatively new with marginal local support.
Thanks in advance,
Carl
As long as I'm asking questions,
Why does the manual say to derate the product 4% per thousand for altitude when virtually every other forced draft appliance derates at 2%?
