Verified Reply- Supplyhouse StaffYes this model includes a Taco Model 0014 circulator
Q: what is the normal working PSI f the Ultra 230 230,000 BTU Boiler. What should the max pressure be for the relief valve? Natural Gas. Thank you
Asked by New Boiler 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffOperating pressure must never exceed 25psi. Relief valve must be set to no greater than 30psi.
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.
Asked by JC 11 years ago
Add your answer
Verified Reply- Supplyhouse Staffyes it is, could be a water flow issue in those 2 zones.
Q: CAN BLACK PIPE BE USED WITH THE WEIL-MCLAIN ULTRA BOILERS.
Asked by joe 12 years ago
Add your answer
Verified Reply- SupplyHouse StaffThis unit may not use ABS pipe venting when using concentric or sidewall vents. It may be used when venting the unit directly.

Q: Do you need to add a special additive if you have pex piping instead of copper.
Asked by Joe 14 years ago
Add your answer
Verified Reply- PexSupply StaffNo additives are required, but you should use PEX tubing with an oxygen barrier.
Q: Can it be used with propane
Asked by Joe 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, this boiler is field-convertible to propane.
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
Q: Existing boiler is well mcclane 175000 btu 80percent ef.what would be the proper replacement size with the95 percent ef.
Asked by Joe 14 years ago
Add your answer
Verified Reply- PexSupply StaffThis 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).
Q: Can it be used with conventional baseboard,6 zone system.
Asked by Joe 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, it can.
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.
Q: do you need a water heater to supply hot or keep water to the boiler,or this boiler supply it own hot water for heat. It because i have a tankless water heater,thanks
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThis 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.
