Raypak’s Residential Boiler Product Family

Raypak revolutionized the boiler market in 1948 with the first
innovative high recovery boilers that utilized superior finned

opper tube material. Our successful designs became the bench-

c
mark by which all other boiler designs were judged for efficient,
reliable and durable hydronic heat.

At that time, Raypak was the first American manufacturer to
provide an innovative family of heating products that used supe­rior copper and bronze materials in the construction of their
heat exchangers. Up until that time, all manufacturers used
energy wasteful high mass cast iron and steel in the construc­tion of heat exchangers.

We direct our Engineers to consider innovation of a new func­tion or feature into the boiler’s basic design to be a requirement
of every new product. Additionally, the innovative feature pro­vided to the end user in a manner that is apparent and benefi­cial to the user, rather than as an unfathomable abstraction.

For over half a century, Raypak has led the trade with innovative
boilers that utilized finned copper tubes as the primary material of
choice for heat exchangers. Raypak has found the necessity to
increase choices in materials, so that copper, as well as aluminum
alloys are available for the construction of heat exchangers that
are suitable for any application or environment.

Recent legislative activity throughout the Unites States, where
Municipal, State and Federal Governments have created various
incentive and rebate programs in order to lower non-renewable
energy consumption at the consumer level. In the process, these
incentives have enhanced the marketplace for higher efficiency
boilers.

Raypak’s family of Hydronic boilers allows every homeowner’s
possible needs to be satisfied. Raypak provides easy, reliable sin­gle source provision of modern, Energy Star listed designs made
in the USA or Europe that are backed up with the best service
and support network in the trade.

This brochure features three Raypak families of residential boil­ers, ranging in size from 42,000 to 300,000 Btu. The specific con­struction varies. However, all product lines are at the cutting
edge of operating efficiency feasible for their particular design.
This ranges from 83% AFUE for the reliable and time proven
Raytherms, to the mid 90's for the condensing versions in which­ever size fits your needs. Choose a hydronic system to maximize
your family's comfort, and select whichever Raypak model best
meets your individual preferences from this complete array.
