Available in Upflow and Horizontal configurations, the NPF comes in two sizes of 60,000 Btu/h and 100,000 Btu/h.

An installer is asked to add a monobloc-style air-to-water heat pump to an existing hydronic system that is supplied by a mod/con boiler.

A technician encounters a system installed in the 1980s when radiant floor heating was relatively new in North America.

A homeowner hires a heating contractor to upgrade his propane-fired cast-iron boiler to a mod/con boiler. The cast-iron boiler is only 15 years old and in good shape. 

A client asks a heating contractor to set up a floor heating system for a new 7,500 square foot machine shop.

Some renewable energy heat sources require large thermal storage tanks. Examples include systems’ biomass boilers and solar thermal collectors.

With flow rates from 50 to 7,000 gpm, PF Series heat exchangers are capable of handling a wide variety of system requirements.

In last month’s Hydronics Workshop column I described five devices that would, in my opinion, improve and expand the North American hydronics industry.  Here’s my “wish list” from that column:

Extended protection applies to units specially engineered to streamline tankless-for-tank projects by reducing installation time and costs.

Lars Rasmussen will focus on continuing to grow and develop Danfoss’ heat exchanger product portfolio and research and development efforts, and contribute to the growth of heat exchangers for refrigeration and air-conditioning applications worldwide.
