What is a hot water boiler?

A Hot Water boiler works by using a fuel such as oil, natural gas, or propane gas to raise the temperature of an incoming liquid to a desired operating temperature setpoint.

Hot Water Boiler Setpoint

Hot water, heating, or hydronic boilers as they are referred heat a liquid to a specific setpoint. These setpoints change throughout the year as changing outdoor air temperature varies. This is known as the outdoor reset schedule. When temperatures are at or below 32 degrees Farenheit, the boiler may run at an operating temperature setpoint of 180 degrees Farenheit. However, as temperatures heat up the boiler sets the setpoint lower or stays offline as no heat is required.

Why you need an efficient hot water heater?

Hot water heaters need to be properly maintained and serviced so that the setpoint is optimized for the right temperature. This helps maximize the heat transfer process to get as much heat energy as possible from the entire combustion process.

Standard vs High Efficiency Condensing Boilers

There are two types of condensing boilers: Standard and High Efficiency (HE) Water heaters. The main difference is that High Efficiency heaters have a secondary heat exchanger to maximize heat transfer. For a boiler to be considered High Efficiency, it must have a thermal efficiency of over 90%. We offer standard and high-efficiency boilers to meet your needs.
