THE COMPACT MINI-THERM
™
FOR SUPERB HOME HEATING COMFORT
LAARS MINI-THERM gas-fired residential hydronic boiler is an ideal heating appliance
that can reduce homeowners heating costs and has plenty of capacity to keep even the
largest home comfortable on the coldest days. The compact boiler has a low-mass heat
exchanger and a super-quick heating response to meet your residential application
requirements. The Mini-Therm comes in two varieties, JVS-spark ignition and the JVH-hot
surface ignition with induced draft. Each is designed to meet specific
installation needs while being energy efficient and light on your budget. Natural or
propane gas models are available.
UNIQUE HEAT EXCHANGER DESIGN
Laars engineers developed a copper tube heat exchanger
with small cast iron “wet-walls” to combine the benefits of both
material properties while removing their potential drawbacks.
Features include a low-mass heat exchanger and quick heating
response to meet residential application requirements, ideal for
new homes or replacement boilers. Heat exchanger reliability
has been field proven over many years, be assured that the
Mini-Therm will provide heating comfort and dependability.
COMBINED BENEFITS OF COPPER AND CAST IRON
•Heat is transferred up to 7 times faster via copper than cast iron.
•Less copper is needed to heat the same amount of water as compared to full
cast iron boilers, resulting in a smaller and lighter boiler.
•The small cast iron wet walls act as mini heat sinks to hold just enough heat to
help minimize boiler short cycling. This helps increase efficiency and boiler life.
THE MINI-THERM IS THE PERFECT BALANCE OF TECHNOLOGY, EFFICIENCY AND VALUE.
