Figure 1 shows the piping layout for an actual installation. It uses two boilers, fired in stages, to supply three areas of a building. One of those areas is sub-divided into three zones. The other two areas are handled by individual zone circulators. The "primary circulator" operates whenever any load circuit is on. All circulators are fixed speed. There's a partially closed ball valve at the end of the "primary loop."

Around 25 years ago, I developed a design that sends high-temperature water to a remote manifold for low-temperature floor heating, mixing it with returning water to achieve the optimal supply temperature, regulated by a variable speed pump. Can you identify a problem with this approach or propose a better one?

The radiant heating market is one that took the industry by storm in the early 2000s. More than two decades later, the acceptance and applications of radiant systems have grown exponentially. Experts describe the radiant heating market in 2022 as “consistent” and “expanding,” citing labor, material and logistic uniformity shortages as the top challenges hindering radiant projects.
