Outdoor Reset with Auto Differential Control – Outdoor reset continuously adjusts the boiler heat output
to match outdoor conditions. The boiler control does this by reading the outdoor temperature and
calculating if there will be a heavy demand or light demand on the boiler based on past history.
The controls can compensate for a fast response (cold days) or slower response (warmer days) to
reduce fuel use. It also makes it very easy to install since target temperature set points do not need to
be setup, the boiler automatically knows what to do!
Space Heating with Domestic Water Priority – when an indirect water heater is installed with the
Mini-Therm and there is a call for both space heating and domestic water heating the controls
will make sure that the domestic water is heated first and then returns to heating the home.
This ensures there will always be plenty of hot water at every point in a home.
Mini-Therm boilers offer exceptional value with “high performance hydronics” that give customers
the highest performance at the lowest cost. By far, Mini-Therm is the right solution for any
size residential home heating system.
The Mini-Therm boiler operates at peak efficiently based on our latest controls upgrade that includes
advanced programming to reduce gas consumption and minimize utility bills. This new control also makes
the Mini-Therm an easier to install boiler, with a new auto set-point feature that automatically determines the
boiler target temperature.

MINI-THERM ADVANCED CONTROLS
The ingenious Laars-Stor
™
water heaters are
engineered to provide the highest hot water
output at the lowest pressure drop of most any
indirect fired water heater in the industry.
Hot water from the Mini-Therm enters the coiled
heat exchanger that sits inside the Laars-Stor
tank. The heat from the boiler water is efficiently
passed through the heat exchanger coil to the
domestic water in the tank. The tank and boiler
can be located very close to each other resulting
in minimal space used. The Laars-Stor is packed
with features to ensure many years of safe, hot
water when you need it!
