Hi Efficiency Boilers

A resurgence of radiant floor designs has re-introduced many to the wonderful advantages of hydronic heat. With this, a new style of boiler has emerged; the radiant heat boiler. Ultra high efficiencies of up to 98% have made this a choice for those concerned about energy efficiency or the environment. Clean, quiet, and compact, these boilers require a new level of contractor technical knowledge to install than previous, older cast iron boilers needed. And, of course, we have that knowledge... with plenty of installed systems in Wheaton to prove it.

Free Computerized System Sizing & Analysis

We take care on every installation, going the 'extra mile' to make sure that your system will work as promised with the use of computer sizing programs. Oversized furnaces experience shorter lifespans, produce uneven heat, and are less efficient. Undersized systems simply won't keep up when you need them most. Instead of trusting another's work from decades ago, we take the approach that your home deserves a fresh analysis; spending on average 2 hours for every estimate we do. 'Close enough is good enough' sizing and installations worked on old furnaces, but today, sloppy techniques with modern equipment will produce a non-functional system. Period. 'We at Armbrust have a 100 year reputation to protect in Wheaton' Trust us to show you the right installation for you.
