Features
The Laars Mini-Therm JVS series of boilers is a broad application residential boiler designed to fulfill the needs of a large variety of homes. Its most prominent feature is its unique heat exchanger design. A core of small cast iron wet walls is encased by copper in a tubular formation, taking advantage of the best attributes of both metals while removing many potential drawbacks. The built in draft damper helps prevent your gas payments from needlessly dissapearing up the chimney instead of being used to heat your home.
Product Features
Hybrid Metal Heat Exchanger
The Mini-Therm uses a heat exchanger comprised of both cast iron and copper. Cast iron "wet walls" add durability to the heat exchanger's construction while copper tubes facilitate high levels of heat transfer.
Automatic Draft Hood
The JVS Mini-Therm comes with an automatic draft hood. This draft hood reacts dynamically to the amount of flue exhaust currently being generated, and helps to prevent your energy dollars from needlessly escaping up the chimney before all of their potential energy is used.
Fast Heating Response
The internal design of the Mini-Therm keeps the time between your thermostat activating and heating being delivered to your home to an absolute minimum.

Medium
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Fuel Type
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
