Cast Iron
Fuel Type To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Oil
Combustion Type
Conventional
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.
Chimney Vent
DHW Production DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.
