Hydrolevel EL1214-P Sensing Probe

The Hydrolevel EL1214-P (Part Number 45-226) is a heavy-duty standard ceramic sensing probe engineered for precise low water cut-off (LWCO) functionality in both residential and commercial boilers. Featuring a 3/4" NPT threaded connection, this probe is specifically designed with a 1-11/16" long nut to accommodate systems with thicker boiler jackets, ensuring a secure and leak-free installation. With an inside dimension of 2-7/8", the EL1214-P provides reliable conductivity sensing to protect heat exchangers from dry-fire conditions. This authentic Hydrolevel replacement probe is a critical component for maintaining the integrity of Safgard and HydroStat control systems. Contractors often prefer the P-series model for its robust stainless steel construction and the extended hexagonal nut reaching past insulation layers, making it the primary choice for boiler safety control maintenance and HVAC level sensing upgrades where standard probes fall short of the jacket depth.

Key Benefits:

• Extended Nut Design: The 1-11/16" long nut is Purpose-built for boilers with thick insulation or heavy jackets, providing easy tool access during installation.
• High-Durability Ceramic: Features a high-grade standard ceramic insulator to prevent signal tracking and ensure accurate water level detection over long service lives.
• Universal 3/4" NPT Fit: Standardized threading allows for seamless integration into most low water cut-off manifolds and boiler tapings.
• Corrosion Resistance: Built with high-quality materials to withstand the harsh chemical and thermal environment inside a pressurized hydronic system.

Common Questions:

Will this probe work with a Safgard 1100 series control?
Yes, the EL1214-P is compatible with various Safgard and HydroStat models requiring a 3/4" NPT probe, provided the 2-7/8" insertion length matches your manifold requirements.

What is the difference between the EL1214-P and the EL1214-SV?
The EL1214-P features a longer nut (1-11/16") and a standard 2-7/8" length for thick jackets, whereas the SV model uses a shorter nut and a 2-1/16" length for installation in standard reducing tees where clearance is limited.

Can this probe be cleaned?
Technicians can typically clean the probe tip with fine emery cloth to remove scale buildup, which restores proper conductivity and prevents nuisance low water shutdowns.
