Laars Mascot FT HTP P-950 EH Details
The Laars Mascot FT HTP boiler series, featuring the P-950EH Control Display, stands out as a highly efficient and versatile solution for residential hydronic heating. Achieving an impressive 95% AFUE, it dramatically reduces energy consumption while offering precise control. Its sophisticated modulating gas valve allows for dynamic heating, adjusting output from 100% down to as low as 10% on the 199 MBH model. This wide turndown ratio ensures optimal comfort and efficiency by precisely matching heating demand, avoiding wasteful on/off cycling.
This boiler offers exceptional fuel flexibility, configured for Natural Gas (NG) from the factory but readily field-convertible to Propane (LP) with an included conversion kit. At its core is a durable stainless steel heat exchanger with finned aluminum core fire tubes, designed for low pressure drop and long-term reliability. The advanced pre-mix ceramic fiber burner ensures clean combustion, contributing to a Low NOx system that surpasses stringent air quality regulations and promotes environmental responsibility.
Central to its user experience is the P-950EH Control Display, providing an intuitive interface for monitoring and adjusting system parameters. It integrates advanced features like outdoor reset functionality, which intelligently adjusts the boiler's target temperature based on external conditions. This proactive control enhances energy efficiency and maintains consistent indoor comfort. Furthermore, the system accepts external 0-10VDC temperature setpoint signals, enabling seamless integration with sophisticated building management systems for enhanced automation.
Safety is paramount with the Mascot FT HTP. It's equipped with multiple protective devices, including an ASME 30 psi pressure relief valve to safeguard against overpressure within the heating system. An automatic low water cut-off (LWCO) prevents damage from dry-firing, while overheat temperature sensors and a burner overheat switch ensure safe operation under all conditions. Additionally, it features both blocked vent and condensate pressure switches, alongside a gas leak detection system for comprehensive safety monitoring, alerting users to potential issues promptly.
Installation flexibility is a key advantage of this wall-mounted unit. It accommodates various venting options, including direct, single, or concentric vent configurations, utilizing common, readily available materials like PVC, CPVC, polypropylene, or stainless steel. The unit comes complete with essential accessories such as a robust wall mount bracket, a pressure relief valve, and a built-in condensate trap that requires no priming, which significantly simplifies the installation process for qualified technicians, reducing time and complexity on-site.
Beyond its powerful performance, the Mascot FT HTP boiler is engineered for minimal maintenance, though annual inspection by a qualified professional is highly recommended to ensure continuous optimum performance and extend its lifespan. Features like the automatic air vent further contribute to hassle-free operation by continuously purging air from the system. Its thoughtful design, robust safety features, and user-friendly controls make the Laars Mascot FT HTP a reliable and energy-efficient choice for modern residential heating applications, offering peace of mind and long-term value.
