Anacortes Boiler Replacement

Anacortes Boiler Replacement, Iron Fireman To Navien

This Anacortes Boiler Replacement project involved this monster of a boiler, this boiler was burning massive amounts of fuel oil to keep my customers home heated, costing them dearly. They felt it was time for a change to something way more efficient and reliable.

A Test Of Time

When ever I remove a old unit like this I try to imagine what the installers where like, where they young or old? And or perhaps how much effort went into installing such a beast back then. At that time this was cutting edge equipment and they where probably extremely proud of the installation.

 

The Navien Combi/tankless Unit

As you can see the new Navien CH-240 Combi/tankless unit takes up very little room compared to the older monster of a boiler ... and not only does it heat the home, it heats the hot water as well. I have installed a few of these now with very little issues. They work exactly how they are advertised. The only draw back with this Anacortes Boiler Replacement is that it takes a little longer to get hot water compared to the standard Navien NR-210a tankless.

 

Conclusion

This Anacortes Boiler Replacement turned out great for our customer, the Navien heats both the home and the hot water(endless) and is super efficient. This is one of my favorite installations and I highly recommend doing this for anyone in the same situation.

Munchkin Boiler Replacement

Munchkin Boiler

Costly Munchkin Boiler.

Almost every Munchkin boiler we come across has a history of problems. This particular Munchkin just started to have issues ... my customer elected not to go down the costly repair route that these boilers are famous for.

The Flash Boiler

The idea behind this Munchkin Boiler is to flash heat the water, by doing so you have a very small compact unit. BUT in my opinion its this compact design that can led to serious issues, like clogging of the burn chamber and or the heat exchanger itself. This type of clogging can lead to serious costly failures.

Munchkin To Burnham

The new Burnham ECS boiler is a cast iron boiler with an optional outdoor reset, perfect for this application. The Burnham boiler efficiency is a little less than the Munchkin Boiler but I feel it is a more reliable, and will last a lot longer with fewer repair bills.

Conclusion

Flash boilers have very small ports on both the inside and the outside of the exchanger, without proper maintenance they will clog and cause costly repairs.

Bow Wa Boiler Replacement

A Clean, New Installation in an Existing Home

Bow Wa Boiler Replacement.

When it comes to boilers we really don't have a favorite brand or model, we actually look at the situation and then pick a boiler that will actually work the best. That being said, we do have a list of favorite boilers we like to use. In this Bow Wa Boiler replacement the Burnham ESC boiler fit the bill.

Maintenance was the key

Our customer actually had a fairly new high efficient boiler already installed, the problem was it kept breaking down. So much so that he decided to have it replaced with a much simpler boiler. As it turned out we had found that the top of the heat ex-changer was almost totally plugged and the gas pressure going into the boiler was not properly set. All of this was overlooked for years by the company doing his maintenance, and that company was the original installation company.

The Burnham ESC

In this situation we had picked the Burnahm ESC boiler, reason being they are very basic, durable, easy to install and you can add modules to them. The boiler is great in low temperature applications, like for in-floor systems or it can easily handle high heat base boards applications as well.

Conclusion

Make sure when your having maintenance done on your boiler system (especially high efficient systems) that its done properly. A good installation company is not always a good service company.

Weil Mclain Ultra Boiler Issue

If you own a Weil Mclain Ultra Boiler, this article is for you.

We have a customer in Anacortes WA with a WEIL McLAIN Ultra Boiler 105. Their boiler is propane (LP), uses a side wall termination kit provided by WEIL MCLAIN and is on the coast pulling in salt air for combustion. This particular boiler has given us trouble for many years. Usually boiling down to a bad air fuel mixture, but on occasion we had to replace parts. All done with tech support on the phone.

WEIL McLAIN Ultra Boiler Venturi

This last service call shed some light on some of the issues, the venturi was compromised, literally falling apart. When we contacted tech support about the venturi they stated that the venturi only has a life expectancy of 5 years! Not only where we shocked to hear the 5 years, we where even more shocked that the existing venturi was replaced by Alpine Heating And Cooling only 2 years ago.

 

High Maintenance

If you own the WEIL McLAIN Ultra-105 boiler or considering purchasing one, keep in mind they require a yearly maintenance. The yearly maintenance has to be done with a kit that they supply, that kit is expensive and the labor to perform this maintenance is extensive. Also keep in mind that every 5 years you maybe buying the ULTRA-105 gas valve replacement kit #383-501-030, also very expensive. On a final note we share service information with another service contractor in our area, they as well are having issues with another  WEIL McLAIN Ultra boiler ... but model Ultra 80. So we don't know if this problem is just for the model 80 and 105 or spreads to all sizes.

 

Conclusion

The WEIL McLAIN Ultra boiler is not a boiler Alpine Heating and Cooling recommends, especially if you're LP and or living on or near salt water. Keep in mind the boiler is a high maintenance and is very expensive to repair.

Roth 1050 controller

Roth 1050 Controller to Honeywell AQ25244B

Boiler Controllers

Boiler controllers can be very intimidating, especially if you do not deal with the same controller all the time. To make matters worse we had a burnt out Roth 1050 controller (Tekmar) that provided zero information on the installers custom settings. The Roth #1050 was manufactured by Tekmar, Tekmar was a leading manufacture and provider of boiler controllers. That was until the industry they provided controllers to caught up to their technology and started to produce their own controllers at a much more reasonable cost.

Burnt Controller

After removing the circuit board from the housing you can see under the blue capacitor a burnt spot, now in some cases you can have these boards repaired, unfortunately this board was beyond repair. And the very sad part is these boards are becoming scarce and very expensive. Our solution was to move to a Honeywell AQ25244B controller with a AQ25744B expansion panel. Honeywell is less expensive and readily available.

Not only would the Honeywell controller replace the the boilers Roth 1050 controller it would also replace the 2 Taco zone controllers that where on the system as well.

We installed the Honeywell AQ25244B controller in a more accessible area for the home owner as well as for the service technician. Because the new controller did the task of 3 components all the wiring had to come back to this location.

Boiler System Back Up And Running

Once the new Honeywell controller is installed we still have a few hours left configuring the system and to make sure the system is working correctly.

Monster to Weil McLAIN boiler

Old Boiler

The Weil McLAIN Boiler

 

This Monster had to go

I do not know any other way to describe it, the older American Standard boiler was originally an oil fired boiler that had been converted to natural gas. Just to let you know one of the worst efficient systems out there are oil systems that have been converted over to gas...bad bad bad. This particular boiler I am guessing at 40% efficiency at best... and I'm being nice.  The boiler weighed well over 800lbs and took 2 vans, 3 men and a block and tackle to get it out of the basement and into a van.

 

Weil McLAIN Boiler have come along way

As you can see the new Weil McLAIN Boiler  #CGA is not only half its size, its 83% Efficient, more BTU's, quieter and 2 men can carry it. How is that for technology!

Bradford White combi-core

Bradford White combi-core

Bradford White combi-core not heating

Every once in awhile you come across a good install, but poor design. Here we have a Bradford White combi-core (Boiler) hwt. These tanks heat both the domestic and hydronic water without mixing the two. The first thing I look for when I'm called out on a no heat boiler call is water pressure, and in this case there was no gauge. Not only was there no gauge...there was no pressure relieve valve. I determined there was massive amounts of air in the system, the pressure regulating valve was shot (no water coming in), and their expansion tank was faulty.

 

What we replaced and added

I replaced the expansion tank, replaced the cheap pressure regulator valve, added a pressure relieve valve and pressure gauge. Now if they ever have issues again with their Bradford White combi-core at least the tech can see if there is pressure in the system ... and if the pressure gets to high it has a place to go. I also found a faulty Wirsbo zone valve, and of course replaced it as well.

Navien Combi Water Heater

Navien Combi Boiler Weekend Home

Navien Combi Water Heater

At first glance I was taken back a little by the material being used in this water heater system. I have never seen black rubber hose being used in a in-floor application. It was not only the rubber hose being used but the size of the hose, 1/4" Id just does not seem like a lot of surface area to me for in-floor.

Existing Black Rubber Hydronic Hose

Existing Black Rubber Hydronic Hose

The black hose simply pushed into the copper pipe to make a manifold, the pressure of the system keeps its sealed. My research concludes that 45psi is the max these connections could hold back. We are running 12 to 20 psi.

  Here you can see the older Combi-Core water tank that was used to heat both their domestic as well as there hydronic heat. The mixing valves being used appeared faulty and both expansion tanks where bad.

 

Navien Combi Water Heater ... cont.

Navien has really out done themselves in my book with the Navien Combi Water Heater. This unit not only heats your domestic water, but also heats your home ... all in the same box.

New Navien CH-240 Water Heater

New Navien CH-240 Water Heater

 The Navien CH-240 tankless bolted right up on the exterior wall and really was plug and play, well of course we had to build a primary manifold and modify the existing loop to be a secondary loop ... but not to complicated.

 We controlled the Navien Combi Water Heater boiler system with the new ecobee Wifi thermostat, this way my customer can change thermostat settings from a remote location. And this being a weekend home it will work out great.
