Vitodens power

joel_19

last winter we went to a Mcmansion that had two 11 year old Furnasties. She was finishing the basement off and wanted to heat it. I suggested she junk the furnasties and her gas water heater. In thier place we installed two hydro air units and an indirect tank. We also added baseboard to the basement. Powered it all via Vitodens. At the end of last winter the gas company let her skip her last 2 months payement (budget plan) because she had so many credits saved up.

Last week the gas company nocked on her door to announce they where REPLACING her meter , " Because it must be BROKEN Mam since your therms have gone down so much"
She showed him the Vitodens in the basement , he called dispatch to suggest they cancel the meter switch...
Viessmann there is no substitute!
Munchkins are great... with coffe.

I love happy endings like this...

... I wish more homeowners would consider the efficiency of their heating equipment in the light of raising energy prices... Cheers, and congrats!

Must be some kind of mistake Joel

According to alot of people condensing appliances are not any more efficient in a high temp application. You are just making this up right? Just kidding, It is always very satisfying to get that kind of feedback from a customer. The Vitodens is a excellent piece of equipment and has a place in all sorts of applications. High and low temp. Congrats on the results.

Uh huh

That water running out the drain pipe must be from a leak in the boiler cause it's on hydro air right? They also report being much more comfy than with the furnasties. Probably because we oversized the coils and are not baking the air along with longer blower on cycles. Even if the naysayers are correct that during the dead of winter at higher water temps it may not be condensing so what? Your still in the very high 80s with a burner that is modulating to meet your load. That's a bad thing why?

Who says hydro-air is a high temperature application? We have been running our Vitodens w/ hydro-air for only 2 months now, and have stayed very comfortable during a 5F night where the boiler was only firing at about 140F supply temp. Our system wasn't in during the cold spell in early January where we had -5F for a while, but I fully expect that even at -5F (heating curve would predict 145F boiler temp) we will still be condensing as the coil operates at about a 20F delta T. I don't have any runtime statistics, but our on-cycles are very long and operate at very reduced blower speeds.

You're right Larry

Hydro air does not have to be " high temp ". If you have a variable speed blower you can go quite against the traditional idea of high temps for hydro air. Just in case I was misunderstood about using a condensing boiler in such a application, I am totally for using these boilers in all applications. The thermal efficiency is so much greater than a standard CI boiler it only makes sense. Kudos to all who think outside the 1950's.

1950's hydro air

This past Tuesday I asked a customer how he was doing with the "old style" cast iron Buderus/hydroair system we installed last winter (fall of 2003) He now has a full year to compare back.

We took out a ThermoPride with a decent Beckett burner on it and the electric water heater. It was replaced with a G-115 with a 2107 and a 45 gallon Super Store indirect.

Results: To date he has used $525 less fuel oil, his electric bill dropped an average of $31 per month and says the old house has never been more comfortable.

Moral of the story: A carefully designed and installed system with good control logic, even if it's "old school" cast iron, beats a furnace, even a good one like a ThermoPride.

Is there a problem if we do not have variable speed air handlers? We have Trane TWE048.

Another energy-saving success story

If we did more of these there would be no energy shortages. Period.

Excellent timing! Someone else was just asking about a Vito/hydroair setup. I'll bump it up and hope they see it.
