Product Description
Electric Hydronic Block is heating device converts electrical
energy to heat energy through medium of water. Simplied
theory of this conversion is as follows:
Electrical Energy x Conversion Factor = Energy
– Or –
Kilowatts Of Electricity Used Per Hour x 3412 =
British Thermal Units (Btuh) Available Per Hour For
Heating.
• Information is basis used to establish Electric Hydronic
Block ratings (See Table 1 on page 4). Since conversion
process requires no combustion, boiler operates with
highest possible efciency.
• Electric Hydronic Block is constructed with cast iron
boiler that conforms to American Society of Mechanical
Engineers (ASME) Boiler & Pressure Vessel Code. Interior
design allows just enough water to be present for proper
heating element operation - no excess water is stored
which would cause undesirable thermal losses and longer
recovery times.
• Maximum Allowable Working Pressure Water (MAWP) 30 PSI.
• Control system is assembled in modular package keeping
overall size and weight of Electric Hydronic Block to
minimum. Construction of entire Electric Hydronic Block
conforms to Canadian Standards Association (CSA)
Standards for Safety for Electric Boilers.

• Argo Electric Boilers are controlled by electronic control
board maintaining water temperature. Control cycles
heating elements based on heating demand, and
preset boiler outlet water temperature. Control also
operates 120Vac circulating pump rated up to 5A. When
thermostat calls for heat, control will operate boiler to
regulate water temperature at pre-selected set point.
System pump is on whenever thermostat calls for heat.
• This product is not designed for aluminum wiring.
Introduction
• Boiler sizing is crucial. Calculate the maximum hourly
heat loss for each heated space in accordance with
procedures describes in The Hydronics Institute manual
H-22 (Heat Loss Calculation Guide), or method suitable
for local conditions, provided results are in agreement.
• Select appropriate boiler based on accurate heat loss
calculation.
• Do not oversize boiler, sizing is critical for in-oor
radiant heat applications.
• This manual is intended to familiarize installer and user
of Electric Hydronic Block with its installation, operation
and maintenance to assure its normal trouble free
operation.
• Argo electric boilers are designed and manufactured
with quality components for maximum life, durability
and minimum service. Follow installation instructions
carefully before operating heating system for optimum
efciency and satisfaction.
Unpacking
• Remove packaging and inspect unit for damage or
missing parts.
• Report any concealed damage or claims to carrier
immediately.
