Does proper sizing of the boiler really save more money?
Yes it does. When equipment is over sized it causes the product to short cycle which affects the efficiency and stand by losses. It also affect the life of all the mechanicals as they start and stop too often. When a motor or control starts it gets an in-rush of power which can can start breaking down solid state parts. For more information on proper sizing see our heat loss information page which has a link to FAQ on the menu at the bottom of the page.
