Heating Before & After Photos

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.

The cost of home heating oil was killing this client's budget. Her old oil boiler provided both heat and hot water so it ran at 180-degrees all year long including the summer. The Bosch Combi boiler provides heat and hot water at 95% efficiency using inexpensive natural gas. And it only runs when there is a demand instead of wasting all the fuel being hot 24/7. It also varies the temperature of the boiler water sent to the radiators based on the outdoor temperature. this is a great feature that increases efficiency and prevents overheating in mild weather.

This boiler was installed several years ago by a competitor. The house never heated correctly after it was installed! An inspection revealed that it was not piped correctly per the manufacturer's instructions. It also wasn't vented correctly. Steam won't move if air can't move so venting is critical. We piped the boiler correctly and added all new Hoffman steam vents on the mains and radiators. Magically (not really), the house is heating perfectly and his gas bills will be 30% less than he paid last year. Don;t trust anyone other than Alber Service Company with your steam heating system!
