Heating A Large Building
Written by Todd Fratzel. 
Heating a large building can be a real challenge. We are building a 9,000 sf assisted living facility right now at work and I thought I’d share a picture of a really great heating system.
This building is using two Buderus Logano G215 oil fired boilers. These boilers have a high efficiency – A F U E ’s Above 86% and put out between 134,000 to 768,000 BTU/Hr. The two Buderus boilers have been set up to work as a “team”. One boiler will take the lead role for 8 hours while the second one will take up any slack. After 8 hours the two will reverse roles. This helps ensure that the two boilers both 
operate on a regular basis and both get used equally.
For this particular building the boilers are making domestic hot water, providing hot water for two radiant zones and providing hot water for base board heat in individual apartments.
You can check out the Buderus boilers to see all the products they offer. We’ve always had great performance out of their boilers.

Todd, That is interesting stuff. These are modulated boilers? I didn’t know they could do that with oil because of the condensation issues.
Paul,
I’m not really sure if they are modulated boilers…in fact I’m really not sure what that means. Buderus has a pretty good website with all the specs on these. I guess I’ll have to ask my heating guy that question. I know my high efficiency gas boiler is a modulating boiler but I have no idea about these.
I’d look at an open system linked in to a multi fuel boiler, save you a fortune.Good article, so cheers
