HVAC Service Manager - Very Reliable Product

The company I work has installed several hundred of these boilers. I can tell you they are extremely reliable, fairly easy to maintain, and definitely intuitive to troubleshoot. I would highly recommend the Ultra Boilers to anyone.

A Complex Install, but Intelligent Unit

I installed this boiler to replace a 23-year old Smith model that was socking me with $300+ per month gas bills and I couldn't be happier. The first gas bill of heating season was only $91! There are a lot of steps to this install, and you end up jumping around the manual quite a bit to work on all the different pieces, but it's not super complicated. My setup uses 2 zones with independent thermostats and zone valves, so I paired this model with a Taco zone valve controller and they play well together. For anyone in a similar setup, wire your system circulator (not the boiler circulator) into the zone valve controller instead of into the boiler. This prevents the system circulator from running before at least one of your zone valves is open and over-pressurizing that part of the loop.

This machine is a Dream come true

this is a true beauty, the design looks great, the menu is really simple, and the efficiency and the simplicity of this machine is amazing, we are extremely happy with it. I always thought the heating issues at our house was due to poor heating design (we have Radiant Floor Heating), but now I learned that was not the case, it was poor Boiler, ever since we replaced the boiler, rooms that were always cold, are now perfectly warm, sometimes the house got so warm with the settings we used to have, that we have been lowering and re-adjusting the thermostats around the house to make sure it doesn't get too warm. Very happy with this Purchase.

hi efficiency boiler

The 1st boiler that was shipped was damaged, but Supply House promptly shipped a replacement. The boiler has been installed and is functioning perfectly. One call was made to Weil McLain for the system setup and tech support was prompt and courteous.

Working well through many cold nights

We had three of these units installed in 2 old 1930's building that has many old radiators. The system has ran without a hitch since 2012. The system regulates the water flow and temperature by a thermostat outside and inside. The system is easy to monitor and makes the Maintenance Departments easier and more efficient. It has gone through 2 extreme temperature winters in very inefficient insulated buildings without a hitch. Very easily the best piece of equipment in use in our buildings. Highly recommended

Q: My 230 doesn't seem to heat as effectively in 2 of the 4 zones....is the operating temp the same for all zones? Can it be set for individual zones ? Nice and quiet and gas bills went down a good bit. This replaced a 30 yr old unit.

This unit may not use ABS pipe venting when using concentric or sidewall vents. It may be used when venting the unit directly. For more information please see page 6 here: http://s3.supplyhouse.com/product_files/Weil%20Mclain%20-%20383-500-724%20-%20Install%20Instructions%20%28Venting%29.pdf

My ultra 230 came with a orifice (disk) that can be installed for propane use. Check the online installation manual to see for sure if that is still an option. Do not count on getting any help from anyone in the heating and cooling industry if you are DIY and are not a licenced installer. Sent from my Verizon Wireless Device

This Ultra boiler would be a good choice if your current boiler is gas-powered, but it may require different venting methods. Keep in mind that condensing boilers are not able to achieve their full efficiency ratings when they are used to produce "high-temperature" water (above approximately 150°F).

Yes, but you would need a separate zone controller for 6 zones. The on board hardware/software only recognizes 3 zones one being the boiler circulator itself.

This boiler is designed to operate as part of a closed heating loop. This means that it continuously cycles and reheats the same water (for many years, ideally). The only water supply to the unit would be from a pressure reducing fill valve connected to the boiler and a water supply line. It offsets any minor water loss from valves, air eliminators, etc.

A thankless water heater is not needed with this boiler to operate. If you want to use it for domestic hot water you'll need to add a heat exchanger water tank. The water that circulates in these boilers contains ph adjusting chemicals to preserve the slimjnim heat exchanger.

This boiler will operate independently of an hot water system. You can heat your home with it and continue to use your tankless water heater.
