Wirsbo Manifolds

If you have a hydronic heating system, and you have an older Wirsbo manifold system I would think about looking at the condition of that system. In particular I would be looking at the gaskets, these have rubber or ceramic type gaskets, these gaskets need to inspected and or replaced every 10 years(in my opinion).

Here you see a 5 zone Wirsbo manifold(s), 1 manifold for supply and 1 for return. 3 gaskets are needed in each manifold.

Above you can see where we opened up the manifold for inspection, making sure to have drained the water from the system below the manifolds before starting.

Damaged Gaskets

In this manifold we found several damaged gaskets, we elected to replace all 6 gaskets in 3 different locations through out the home.

Commercial Steam Boiler Issues

There is not a lot of HVAC companies that still work on steam boilers, and there is certainly not a lot that still work on commercial steam boilers.

Here we have a older boiler with even older controls, the boiler is dead cold and has a burnt out control board. The problem is getting replacement parts that simply snap into place for these older boilers.

The control board in the picture above that was bad is located on top of the panel box, the new board is installed inside of the panel box on the bottom right. After dialing in the control board and firing up the boiler we realized the condensate pump was not working, the pump was bound up. This is not the first time we had a bound up pump on this system.

We felt because there was no strainer (filter) on the condensate coming back that we would be seeing more issues with the pump and the condensate collector box. We ended up replacing the entire collector box with the pump.

Here you see the new condensate collector box and pump. We also replaced the corroded check valve and added a strainer to the system.

By adding a strainer we will keep debris from coming back to the condensate collector and by adding a valve we can easily clean the strainer.

Laars Pool Heater to Burham Boiler

This Laars Lite pool heater has seen the end of its life, sadly to say it was only 10 years old. The really unfortuate part is that this appeared to be the 3rd pool heater replacemnt since the pool was installed. Fortuantly at this time my customer wanted to do more than just heat the pool, he also wanted to heat the pool room and he did not want to have to replace the heater in another 10 years.

I’m not use to dealing with pool heaters, but after seeing what kind of corrosion can occur I do not understand why pool owners still use them. Now it could be this is a lower quality of pool heater?

Laars Lite corrosion

Never the less my customer did not want a repeat. I proposed using a Burham ES27 boiler with a Triangle Tube MF-135 heat exchanger to heat their pool. This way we have a closed loop system that heats water with water. The pool water will never be introduced into the boiler system. The ES27 is 85% AFUE and is atmospheric, and because its cast iron … its built to last.

Being a cast iron boiler the Burham ES27 did weigh considerably more than the Laars Lite pool heater, fortunately I did have help on this day… I just didn’t feel like wrestling 460lbs all by myself.

Boiler Loop

If you can make it out the Triangle Tube MF-135 heater exchanger is the black cylinder just to the left and down from center. Its hard to believe a small cylinder like that could heat an entire pool. We control the pool loop with a Ranco controller.

Modine Heater

Now for the pool room itself, we installed a Modine HC-108 hot water fan coil. We ran a separate loop off the boiler into the room. We control this with an Honeywell 4000 thermostat. Now for you people that know what a pool room can do to copper … we actually coated everything with a high heat clear coat paint.

My First Triangle Tube Boiler

Triangle Tube was not my first pick for a boiler for this project, but I had to look at all the requirements. The boiler had to be high efficient, I had to get it vented out with PVC, I had to separate the combustion air from the exhaust venting and I had to do all this in a very confined place. Triangle Tube met all the above.

The American Standard boiler had failed, there where several minor issues that could have been resolved but our customer wanted an upgrade. The house was built in the late 30’s and even though the customer feels that this boiler was original I’m thinking its was put in a few decades later.

The triangle Tube boiler fit like a glove, in fact I was within inches of making this a unsuccessful install. I forgot who told me this great advice … “a tape measure never lies” you have to read into it to understand why its called advice.

The boiler comes with its own primary pump but lacks a external pump control, besides the obvious hydronic devices I had to ad a transformer and a relay to make a complete system. The boiler mounts on the wall similar to the Navien tankless. Overall I’m really happy I got to install one of these boilers.

American Standard to Weil Mclain

A bomb in the making, a 35 year old hydronic boiler with failed safeties converted this low pressure water boiler to a high pressure steam boiler. Fortunately no one got hurt when this boiler decided to shake the house and let everyone know it was time for it to be replaced!

Boilers to me are the most fascinating piece of equipment in the Heating world, but not just the boiler itself… the entire hydronic system in the home. Every hydronic system is unique in design and a challenge to diagnose at times. But in this case its was very obvious what needed to be done…replacement.

The new Weil McLAIN CGa boiler fit right into position, the access was no longer from the side facing the HWT but towards the front. This gives the service technician better access. The new Pressure/Temperature gauge now is visible. I added dielectric unions to fight electrolysis’s …and also added shutoff valves.

Skagit County Spaghetti piping

Boiler Spaghetti Piping.

At first look this boiler piping could be overwhelming to a service technician, especially someone not use to hydronics. But I have learned and try to teach not to look at the big picture, but rather dissect piece by piece and it will all come together.

 

Cross Pressurization

The initial complaint from the customer was about not having heat and there where issues with their domestic water. My first look at any boiler is the pressure and temperature. I noticed the boiler was running at 75lbs PSI and the PRV was popping off. I then noticed that the PRV was rated for 150 PSI ... not 30. So there was two issues i found right off the bat. I then found both the domestic and hydronic expansion tanks where also faulty. After turning off the feed to the boiler I noticed the PSI would not drop off ... My attention quickly went to the braford white indirect hot water tank. After several tests I found the coil within the tank to be faulty, bleeding high pressure into the boiler.

Conclusion

The domestic indirect tank had a faulty coil, allowing domestic pressure(75lbs) to bleed into the boiler system(30 lbs).  I found the PRV was not only the wrong size but the also was faulty. Tank was replaced under warranty and the PRV was replaced. All working correctly at this Skagit County Spaghetti piping job.
