Radiant floor heat and panel rads controlled by TRV's!! A Vitodens supplying perfectly modulated output for the whole system and a Vitocell to boot. Sounds like what I'm after in my house come to think of it.

Yes, that would be a cement floor/ceiling. The construction methods in Europe are tailored more toward making something last for 500 years than for "what's your best price"?

My cousin

in Brussels, Belgium has just moved in to his new house that he had built. I told him to take pictures of his boiler room and send them to me.

Look familiar?

PRP?

panel radiators for pets. Nice touch! Not much jacket loss from that boiler or indirect.

Do my eyes and monitor deceive me or is that a suspended concrete slab for the floor above. If so, all through the house?

Of course everyone noticed the TRV on the panel rad.

what is the ...

blue and grey unit next to the water heater? Softener maybe?

Mike T., Swampeast MO

Am I missing something in that very simple piping arrangement or is everything (save the domestic hot water of course) operating at a single temperature with just the circulator in the Vitodens? May be some stuff hidden from view underneath the boiler though...but much of it looks like home-run domestic.

PLEASE don't take this wrong... See how simple (even if the devices themselves ARE complex BUT proven) things look when you use proportionality? Why do Americans think that the cadillac must also LOOK complicated and have so many motors and valves certain to keep the service man happy?

Also

That is my concern with flexable piping. It has to many chances to look sloppy. I have no problem with the new tubing and done right it can look neat. Look at the supplys to the softner and hot water heater, not bad. But the other stuff just looks like the apprentice did it.

Might not be the best looking job

BUT it is the best boiler for any low temp job!!![ever job should be designed with low temps] Then it is the best boiler for every job!!!!!!

Am pretty sure that the only "engine" is in the boiler. Like the burner that modulates with heating demand, the built-in circulator modulates with changing pressure through the TRVs! Really quite an amazing system.

vvrruummmmm

I've done one of these, so I know the basics. What many guys don't understand is that the internal circ on the small units has a very small relaxed pump curve. So, that's why I was wanting to peek at the guts of the sysem. Obviously I don't know how much heat load there is, or what the head losses are for that matter.

Blue and white

device is the water softener (you must be from a hard water area, kevin c) and yes, that is the indirect next to the Vitodens.

I'm curious about the pumping issue as well and will try to find out from my cousin if there are any other pumps besides the on-board one from Viessmann.
