Safe, easy product for boiler repair

When the bricks that lined my boiler fell apart I installed an Instant Glo "Quickie," made by a local company, in their place. Is this product as effective as the brick? A reader Medford, Mass.

You have no reason to be concerned, says the New England Fuel Institute in Watertown, Mass. The product you describe is one of the new advances in boiler repair and, according to a spokesman at the institute, "we feel it is much better than the old brick chamber."

Thus, don't give it another thought.
