Steam boilers – efficient systems up to 31.5 t/h

Viessmann steam boilers: longitudinal supports on the boiler base provide optimum pulling and lifting options for ease of handling. The improved load distribution across the longitudinal supports means less stress is applied to foundations, making them less costly. A boiler base with additional reinforcements is available for earthquake prone

Water Heaters (How to secure them) :: Washington State

Start by placing the strapping at the back of the tank. Bring it to the front and then take it back to the wall. Secure this strapping to the wall studs or the wood block using several 1/4-inch x 3-inch or longer lag screws with oversized washers. If you are securing it directly into concrete, use 1/4-inch expansion bolts in place of the screws.
