Commercial Condensing Boiler with Ultra High Efficiency
The EnduroTi has up to a 93.2% thermal efficiency rating. Older gas boilers may only be using as little as 60% of energy consumed. Heating is the second largest energy expense in most homes accounting for 35-50% of annual energy bills in colder parts of the world. With the EnduroTi 93.2% of the dollar spent on heating is properly used to heat the home/building. That is great savings!
It’s extremely efficient hyper jet combustion system with a modulating inward firing burner allows you to save energy and money.
Versatility
The EnduroTi comes in two models: 750,000 and 1,000,000 BTUs and can be cascaded up to eight units for 8 million BTUs to suit any commercial application. It has the ability to be used in the below applications:
• Radiant floor
• Fan coil
• Base board
• Snow melt
• DHW (with indirect tank)
• Pool heater (with indirect tank)
Model Btuh/Input Range Thermal Efficiency ETI-750 750,000 93.2% ETI-1000 1,000,000 92.5% Incredible Turndown For Bigger Savings
The EnduroTi has up to a 10 to 1 turndown ratio. Its modulating technology matches fuel consumption to demand to provide high system efficiency even during low load conditions. This greater turndown allows the EnduroTi to modulate at lower firing rates which reduces short cycling, conserves energy, and improves component reliability.
A Better Experience With Every Installation
The EnduroTi has the ability to cascade up to eight boilers (with boiler rotation) to satisfy your heating needs! Its small footprint (750k BTU model) will fit through a standard door opening! It has caster wheels on the bottom of the boiler for a smooth moving process.
The EnduroTi eliminates the need for primary-secondary piping. It vents in PVC, CPVC, and stainless steel. It has the option for horizontal, vertical, and indoor combustion venting (confined or unconfined space). Removable access doors facilitate easy access to all components to allow for better servicing.
The HTP Guarantee
The EnduroTi is backed by a limited 10 year commercial warranty, right out of the box! No registration is required.
