Buderus Boiler Reviews - Buderus offers hot water boilers with efficiency ranges from 81.5% AFUE to 95% AFUE* for both Buderus gas-fired boilers, and Buderus oil fired boilers. Selected Buderus hot water boilers can also use PVC venting on selected hot water boiler systems. PVC pipe venting is typically for condensing furnace and boilers where the flue temperatures are low.
Condensing boilers can also use 100% outside air for combustion air, so no air is used from inside the structure for combustion air. That eliminates pressure issues related to furnaces and boilers that use indoor air for combustion air.

What is an Outdoor Reset Control?
An outdoor reset control is a device that changes the setpoint on your boiler based on the outside air temperature. It has been tested extensively and is a proven method of reducing energy consumption therefore saving on energy costs. In some regions, if you have an outdoor reset control, you qualify for energy and tax credits/rebates.
Buderus Sectional Cast Iron Boilers
The boiler comes in sections and assembled on location. Depending on the number of sections in the boiler will depend on the BTU/h output of the boiler. Here is an example of a section. Some boilers will have a few sections, while other boilers will have multiple sections. It will depend on the amount of BTU/h’s needed to heat the structure. That is calculated using Manual J.

Buyer’s Guide | Buderus Boiler Reviews
In the case of boilers, you have a few options for contractors. In some regions, plumbers install and service boilers. In other regions, HVAC companies install and service boilers. Finally, in some regions, both plumbers and HVAC contractors install and service boilers. Therefore, in some areas, you will have limited options for companies competing for your business, while in other areas, it will be highly competitive.
The key for you is to find the most competent, qualified, and reliable contractor who does quality work. Installation of a new HVAC system, whether it is a boiler or air conditioner, is the most important part of the whole purchase experience.
If you get a bad installation, the boiler will not operate properly. Nor will it give you the rated efficiency. It can turn into a very negative experience for you and cost you a lot of money. Whereas, if the installation is completed properly, it will be something you rarely think of, whether it is running or sitting idle. It will be a worry-free appliance that provides comfort for you.
That is peace of mind, and that is what you will get for getting a competent and reliable company to do the installation work. Try reading our HVAC Consumer Buyer’s Guide for some help. It was mainly written for air conditioners and heat pumps, but some of it is still applicable to boiler installations.

We have a Buderus boiler now, we installed it 14 yrs ago. the first 5 yrs were trouble free, worked great, but then the problems started. we’ve had repair after repair, sometimes 2-3 repairs per winter, we replaced the ignighter 4 times, leaks in front and back, gaskets 2 times,,,The company would not help, very disappointed,,, and the problems continue, getting a new boiler before next winter.. NOT A BUDERUS
My furnace has gone up and company wants to install Buderus CG144/4 furnace and I am scared as I know nothing at all about this stuff and have no one to ask. They are asking $8000 that includes all labor and parts. I am 75 years old and want this to be something that will not be a problem. What do you think
Arlene, call another contractor. When someone tells you that the equipment cannot be repaired get a second opinion.
And whenever the equipment does need to be replaced, get at least 3 quotes from different contractors.
Looking for positive experiences ONLY with brands/models gas boiler combi before making purchase
we have had many different companies that came to try to resolve our problems with the Buderas system that we’ve had for 10 years and spent thousands of dollars on repairs and maintenance and still paying…
All of the companies are blaming the Buderas company as they have been replacing and repairing these systems all the time!!!

Buderus is a fine product
Our house has had a Buderus 110K BTU/hour gas fired boiler for 5 years. It replaced a round 1940 monster. We have 5 zones due to various add-ons to the place. A simple system.
House always warm as set. Last week it was -17 degees here.
Quiet. No failures.
Last inspection showed it was CLEAN inside. The technician could not believe it had been in for 5 years.
Of less importance, its blue jacket looks good in my boiler room. [I car waxed it.]
Germans do iron cast parts well.
Any problems with the Buderus boiler are usually due to control problems or installer error. The firing gun and all relay controls are not manufactured by Buderus so they should not be blamed for your problems. Its so fortunate that so many installers do not know what they are doing, and the result is bad reviews for great companies like Buderus. Do your homework people. Dont blame a great company for your installers incompetence.
Thanks for that info Paul . Are you available to come look at mine . It has given me problems from the beginning. First I was burning oil like mad. then it blew out soot all over the cellar and 3 months from cleaning it was black inside . now it is trying to ignite and it bangs and finally does.

HAS NOT WORKED OUT WELL FOR US
We spent the xtra $ for the “best” ,but from the first month thru the second winter we would wake up to 55 degrees ..( 4 zones) .Installers could not fix the issue ,,somewhat because it only happened every 4 to 6 weeks ,, When he decided it must be a bad “”BRAIN” it was past the warranty period.. The supplier would not warranty it. I have almost 1k in bills and still are afraid to take a winter vacation.. Buderus does not seem to have a contact option on their website..Hmm.?

I live in new York Long Island and I am going to be putting in a new Gas Boiler. I have two in mind and would like to know which one is the more reliable unit. One is the Buderus GC124/25 or the Burnham ES2-5 unit. Your opinion would be greatly appreciated for I know very little about Gas Boilers. I was thinking that buying American would be good because of getting parts if needed. But I thought that a German made boiler would be a better product. Which Boiler would you recommend and why? I thank you so much for your input.
