Before & After Photos

With a decades old boiler and outdated hot water heater, this owner's system was unreliable and cost a fortune to operate.

Finding a more efficient way to heat their home and provide hot water, a Bosch Greenstar Combi System was installed to provide 95% efficient heating and water heating. A "combi" unit is an innovative and space-saving solution providing heat and hot water in one insulated unit.

This Customer purchased a vacant duplex wanted 2 furnaces replaced.  

This project was at an apartment building that required several repairs:

1. Remove existing Crown boiler, gas line, flue pipes, pumps and heating pipes.
2. Install a Weil-McLain Ultra 299 modulating/condensing gas boiler.
3. Installation includes PVC venting and fresh air intake, primary/secondary piping, flow check valve, primary pump, secondary pump, isolation, balance and purge valves.
4. Install a new expansion tank, feeder, backflow preventer, and air eliminator.
5. Install manual reset high limit and manual reset low water cut off in header above boiler
6. Install taps off boiler header for future indirect hot water heater.
7. All power and control wiring
8. Start up, test, program and balance system.

This old oil fired boiler and electric hot water heater were costing over $5000 per year in utilities. The home owners were freezing every winter!

A Bosch Greenstar Combi System was installed to provide 95% efficient gas heating and hot water heating in one efficient unit. We also air sealed and insulated the attic to keep the heat in the house.

Utility costs dropped by more than 50% and the homeowner received a $5000 rebate and $10,000 loan at 0% interest through New Jersey's Home Performance with Energy Star program.

This third floor original attic in historic Haddon Township had huge issues with leaking air. This caused utility bills to spike and comfort hit an all-time low.

After air sealing to prevent the leaking air, we installed foam board insulation to keep that comfortable air in.
