Boiler shakes the whole house when in high-fire mode. Replacement parts are not readily available and the unit was installed 3 years ago.

"System environment adversely effected boiler"

5.0 rating

I installed a TriAngle Tube Prestige Solo 110 in Aug 2010. It replaced a 1967 boiler and my gas consumption halved. I absolutely love it! Under the old boiler system, the garage pipes ran outside the house and to keep from freezing (Anchorage AK here) the Taco Valve was in manual open/on position and boiler pump configured to allow it to be on/running 24/7. Thermostat in the garage simply turned on/off a fan, on a always hot radiator. With the new system, I rerouted the pipes inside to the garage and because there was no wiring from garage thermostat to boiler room, I left the Taco Valve in ON/OPEN position for a year until I finally got around to wiring it in. That is when I started having problems. When I configured the Zone Valve from manual ON to auto, when any thermostat sent the ON command, my boiler would come on and within 30 seconds go into hard lock out code with over temp errors. After couple months of frustration and multiple efforts to resolve I finally hit on the problem. Turns out that the Zone controls were wired wrong (worked under the old system OK). When the Thermostat gave ON command, the boiler kicked on immediately. But it takes a minute or two for the valves to open, thus with no water circulating due to the closed valves, it over heats and locked out. As long as I had the one zone in on/open position, the other valves didn't need to be immediately open when boiler was kicked on, as the water would circulate out the permanently opened zone. But when that zone was set to auto, then the issues appeared. When I got the valves all wired up right, the Thermostats effected the valves first, and when the valves open, their switches in turn trigger on the boiler. It took couple months due to the randomness of when it would lock out. Sometimes over and over, others week at time with no issue. It just required a perfect alignment of all valves to being off at same time and no demand on side arm water heater tank, when a demand for heat was made. Lesson learned: Make sure the environment outside your boiler is right, ie, plumbing and wiring controls correctly designed and installed. I share this, hoping others in similar situation may benefit. Posted 1 September 2012

"Wonderful Machine!!!"

Had the boiler and indirect fired Smart 40 water heater installed last month… only 1 month, but none of the problems listed here. I am very satisfied with the operation of the boiler and water heater and would definitely recommend this system to everyone!!! It must be installed by a reputable experienced installer, do not try this yourself, or have your brother-in-law the plumber do it, unless this is what he does.

I recently had a PS 175 installed in my home in Flagstaff approx 11 months ago. The contractor did a wonderful job on the installation. I am very surprised on how quite the unit is. I would definitely recommend this unit to other people looking for a dependable heat source.

I own 17 different rental properties in the Portland area. I had my contractors install the Triangle Tube Prestige Solo Series Boilers in each one them for my radiant heating systems. They have performed so well I recently purchased three more for my private residence.
