Can someone help identify HS Tarm Model?

[DustyDentist]

I'm putting in an offer on a house soon. There is an old HS Tarm in an isolated furnace room. We have no idea if it works or not. An 85yo woman lives there and I doubt its been used in almost 20 years. Any information that y'all can provide would be much appreciated.

I'm hoping to first identify the model. Then with that, i'm hoping to find the user manual so i can hopefully try and start it to see if it works or not.

Lastly, If anyone can help identify what that missing part looks like in the top right of the machine where it looks like a knob or handle should go, i would be appreciative of help there. I wouldn't feel safe trying to start it until i know whether or not that was a critical part or not.

Thank you.

I would contact the pros at Tarm USA
This link has pictures of all the models.

HS Tarm wood boiler history page

HS Tarm wood boilers were imported into the USA starting in 1974 during the end of the OPEC oil embargo. They were sold in North America until 2016.

It definitely needs a lot more clearances around the unit.

If you lift the top cover there should be a tag on the boiler that has the model and when it was made. I have one that looks similar, I think it's a mb55 built in 1979. I would imagine that one is around the same vintage.

You can try this link for a Tarm Manual:

Download : HS TARM MB-Solo MKII (40 / 55 / 75) Users Guide English

If that doesn't work send me your address and I can make a copy of the Manual for your boiler. It looks like an MB 55 Solo.

That hole that you mention at the top of the boiler is just a "cutout" where the boiler has a place for a sensor, gauge, etc. It looks like there is a pipe plug there now. I don't use it on my MB 55. It's an excellent boiler. I've used it every winter for 43 years now.

Good luck!
