APOLLO Manifold Actuator 24VAC normal closed
Was WAY less expensive from MTek and it works as expected on both manifolds I have. (one from MBTek, one not)
My plumber has looked over the tank and is very impressed with the construction. He will install it as soon as the new thermostat I have ordered arrives. Looking forward to see how the addition of it will lengthen the cycling of the boiler.
Work great and app works great too. Only been a couple months so hopefully they keep working good for a long time.
I am very pleased with my new boiler. It is a well-made little unit and was delivered to me complete and damage free. Two mentionable items. First, I had to swap the wires going to the flame detector, other than that the system started and operated perfectly. Secondly, the design of the hopper is not as advertised on MBTEK website. It is unpainted galvanized metal construction with a slide open lid not a hinged lid. I like the design, no complaints there, I’m only pointing out that it’s not what I thought I was getting.
I’ve been operating the unit for about 3 months with no issues. I went as far as to purchase wood pellets from every big box store around and the unit performs the same using all of them. I have even operated the unit on 100% Cherry Pits, and it operated flawlessly.
The one feature that I was really looking forward to, was the ability to use firewood as a small supplemental heat source. I started a firewood burn twice now, just for fun. It does a good job controlling the solid wood fire. I was pleasantly surprised. My only complaint is that, at the end of the burning, I have to manually switch the unit to pellet mode. I hope that there is a software update (or I figure out how to set it up properly) that it will allow the unit to automatically switch over to pellet fuel after the solid wood fuel burns out.
Lastly, I would highly recommend MBTEK. They have answered several of my questions in a timely manner and are very easy to contact.
So far I have been happy with the MBTEK Duo 300 Boiler. It took a long time to get the unit, but it seems to be very well built. This is a very large Boiler, We have 4 buildings that this unit is heating. It has kept everything warm through the recent Blizzard and cold spell, so I am pleased with the output. We are still trying to get the settings right so that we are not using too much fuel, but that will come with time. The biggest complaint I have is that the unit only reads in Celsius, and cannot convert to Fahrenheit. Also the unit runs on 230v so has to have a power converter.
So far it’s been fantastic, does 2600 sq house along with domestic hot water. Was a little confused when it came in with a euro plug but customer service was extremely helpful with very quick responses.
