Up on blocks ...

Frank_3

I notice that some folks put boilers up on blocks of some sort, and others don't. What is the purpose/benefit of raising the boiler those few inches? Is there some code requirement, and if so what's the required height of the blocks? (And which code?)

Why on blocks?

#1 Flood - #2 Can make piping easier - #3 ? to early to think on a Sunday

wrastleing

I like boilers up where you do not have to wrastle the ground to service them. a 2 ft. high stand is made of iron angle and bolted to the floor,(The expansion tank goes under the boiler). This was accomplished for a Slant Fin mounted in a garage. Have also seen it done in a basement. Nice to walk up to them. Up oof the floor carring dust. easy to service, cleaner looking installation.

Housekeeping Pads

Most commercial projects require the boiler room equipment that sets on the floor to have a 4" high or 6" high concrete "housekeeping pad" under such equipment.

This makes for a neat looking installation, keeps water on the floor away from the equipment, keeps debris from accumulating under the equipment, etc.

The same thinking would apply to residential installations...just looks better and more professional than concrete blocks or nothing at all...in my opinion.

Whether it's dirt floor...

or concrete I just feel that it helps to keep the condensation out
from under the boiler....you have a large temp. difference between
teh boiler block and the cool floor... often in a basement that has a bunch
of moisture.
Then add as has been mentioned.... it makes piping and servicing easier,
and makes the job look neater.

Steam or Hot Water

If you're talking about steam boilers, it could be that the installer wanted to keep the wet returns wet; if you drop a replacement boiler too low, you run the risk of dropping the water level and loosing a water seal. Steam can back up into the mains and cause water hammer.

Big plus

On a lot of American made units the insulation is in the jacket so the bottom of the boiler is exposed. Putting the boiler up on blocks helps keep the concrete floor from sucking heat out of the boiler.
