Too much baseboard

Ron W.

I need input. Doing a boiler replacement. I committed a mortal sin and relied on the homeowner to supply information on his heating system. He told me he had 7" high baseboard in his house and there was 292 feet of it. Mid-day I finaly go upstairs to find hi-output radiation throughout the home. To make a long story short, I did a heat-loss of the home to find that there is 242,000 btu of radiation in a home with 68,000btu load. We're installing a Buderus with a 2107 Logomatic. I am thinking constant circulation, letting the reset control the room temperatures. Any other ideas are most highly welcomed and appreciated. Ron

Ron, I see this as an opportunity! More baseboard means you can run lower temps. I would install a great outdoor reset mixing device and take advantage!

Never too much baseboard!

Constant circ with the roomcomp turned way up would be the way to go! Just pick a good spot for the room sensor and you should be fine. How many zones is this? What series boiler is this? Just wondering about hoe much cold water is going to be coming back to this boiler cause it sounds like you'll be running really low temps with all that extra radiation! I know that you've got pumplogic though so you should be ok. It's not dummy board he mesured is it?

Ron, I think Ray and Josh nailed it

so the only thing I'll add is, when you set the system up to run at the lower water temps the system needs, it will save a lot of fuel and your customer will think you're a genius.

I agree

I just doubled the amount of baseboard in a customers house and installed a condensing boiler. I expect lower water temps. and lower bills. Bob Gagnon

Never too much

Ray, We have two zones, two split loops. I checked the element my self and found very little dummy space at all.
The boiler is a G215 series so I'm not worried about temp shock. Thanks for your input. Ron

Lucky home owner

You customer is lucky. What will you use for a design temp? You could probably use a 145 degree max water temp.

Thats sweet, the R2107 putting out 110 degree water during most of the heating system.

Too much baseborard

To all responders, Thanks for the re-inforcement of my thoughts for constant circ. Good knowing others out there study, work in, and care about our trade as I do. With todays technology we can do some marvelous things, can't we. Thanks again, Ron W.
