ray vs triangle tube vs knight boiler

Sam Smith

Having a new construction home being built with infloor radiant heat and a indirect fired water heater. We got three bids and each contractor gave us a different choice. Each gave simular price quotes. How do we know which boiler system is best.

Good Question

Pricing is usually not the lone indicator of quality, so if the contractors pricing is an "apples-to-apples" comparison, why not ask to look at their "apples". Does each contractor have a portfolio of their work with references? Are they factory trained? Does their service tech and/or distributor carry parts if down the road some component fails?

Start asking pointed questions about their workmanship and the good, better, best contractors really start to shine.
What trainings or certifications does the shop or installers have? Do they provide system documentation (although not all contractors do) for the system they design and install?

Spend some time with each contractor. Each of the boilers are reputable (I prefer the Knight Boiler) so you are to be commended in trying to assess which contractor is best suited for your project.

Good luck.

As we say...

time and time again hear on the wall, it's about the boiler it's about the installation. We are all have our preference's based on Distributor and Manufacturer relationships, being familiar with the product and of course quality. All three products you mentioned will work very well if designed and installed correctly.

You will find many arguments about " which boiler is best " here on the wall, at the end of the day it doesn't matter if it is TT, Buderus, Burnham, Viessmann, Weil, Lochinvar, Munchkin, NTI, Peerless, Crown, Ect. They all work well when applied properly.

Go with the guy you feel will give you the best job, as stated in the previous post, check out his apples!!!

I like the Ray (www.knowsomethingmore.com) for a few reasons:
Pros:
1) cast iron has been around for years and is bulletproof.Heat exchangers made out of aluminum or stainless who knows how long they will last.

2) Uses a unique indoor reset control based on actual indoor conditions.

3) Its AFUE is 92.7 % similar to boilers using stainless heat exchangers.

4) Usually no primary secondary piping required.

Cons:
1)Heavy can't be wall mounted and takes up a lot of floor space.( working clearance etc )

2) Uses expensive venting system.

3) Sort of new to the scene in residential version. Commercial version KN has been around lot longer.

My second choice would be the Triangle tube . just my opinion.
