Upgrading Old Systems

Rohde 007.jpg

One large residential client had us upgrade their oil furnace to a propane boiler system. The old oil furnace was way undersized (98000 BTU) and located on the wrong spot This was a 9000 sq. Log home with 12 In floor heat manifolds and over 13000 linear feet of in floor heat tubing and needed 270000 BTU.

This undersized oil furnace was running 24/7 and never could keep up to provide the required heat.

We fix new, but poorly installed systems all the time.

On the left side above we have a brand new system that was installed in a way which the boiler was running constantly. The system was installed by a professional company in town but without the correct understanding of how to make these systems run as efficient as possible. On the right you can see how we cleaned up the mess removed unneeded parts and got the system to heat the home with a drastic cut in gas consumption.

On the left side above we have a system that was installed in a way with to much elbows. Every unnecessary elbow or tee in the system, make's it run less efficient The system was installed by a professional company, but without the correct understanding of how to make these systems run as efficient as possible. On the right you can see how we cleaned up the mess removed unneeded parts and got the system running way more efficient.

In this case, the primary and secondary loop was installed with black pipe, an absolute no no. Those Boiler systems should be installed in copper only (less corrosion and debris in the boiler and system).

There was also a regular check valve installed in the boiler feed line, instead a backflow preventer.

The system was installed by a professional company, but without the correct understanding of how to make these systems run as efficient as possible. After we finished the system the right way, we were able to drop the output heat from 180F to 130F. This is a huge savings on propane for the customer.

This boiler system on the left was installed by one of the biggest heating companies in Sault Ste Marie. Almost everything installed improperly and was missing a lot of needed parts.

 

1.) Primary and secondary loop with wrong layout and too small of pipe sizing.

2.) Missing isolation valve sets on heating or domestic water side (important for descaling the boiler)

3.) Missing Air Separator

4.) Expansion Tank to small

5.) Circulation pump wired direct (running 24/7)

6.) Room thermostat was installed within 2 feed of boiler (to close, calls for heat al the time)

 

We cleaned up the mess like it should be. The Navien Boiler is now operating high efficient and with a heating temperature from 120F
