New Oil Boiler & Indirect Water Heater

This installation included a new PurePro Trio oil-fired boiler paired with an indirect domestic hot water heater.

The indirect water heater uses the boiler to produce domestic hot water, providing the home with both reliable hydronic heating and hot water from an integrated system.

We take pride in keeping our boiler installations clean, organized, and serviceable, so the system is easier to maintain for years to come.

Oil-to-Propane Boiler Conversion

This customer chose to move away from oil heat and convert their home to propane heating.

We removed the existing oil-fired boiler and installed a Bosch Greenstar propane boiler, along with the necessary hydronic piping and system components.

An oil-to-propane conversion eliminates the need for oil deliveries and on-site oil storage while giving the homeowner a modern, high-efficiency heating system.

Another successful fuel conversion by Sprague Heating & Cooling.

Propane Furnace & Central AC Installation

This project was a complete heating and cooling system installation.

We installed a new propane furnace and central air conditioning system, along with new ductwork throughout the home.

New equipment is only part of the equation. Properly designed and installed ductwork is critical to delivering consistent airflow and getting the most out of a new HVAC system.

New furnace. New central AC. New ductwork. Complete comfort system.

Another Bosch Greenstar condensing gas boiler, boasting a 95% efficiency. Compact and space-saving, available in floor mount and wall mount models. This model makes heat only and is coupled with a high efficient heat pump electric water heater, using 1/3 the electricity (vs standard electric water heater) to make hot water while dehumidifying the basement.
