We made a decision to put an addition on our home. Having been fortunate enough to get contractors in the family made this a fairly easy decision. Framing, electrical, and plumbing were looked after with ease. We then located the choice of how we might heat the space. The choices were limited because we had an existing system in the house. The original part of the home was heated with a furnace and had two zones. The boiler was perfect for the space that it was required to heat. We contacted a local HVAC company to determine what choices were available. Faced with the very costly choice of upgrading to a larger boiler and adding still another zone, they suggested a vent-free gas heating appliance. This system operates without a chimney, flue or vent, so you can install a system just about anywhere. We chose a wall mounted vent free unit that was sufficient for the new place. Another advantage to this system is that it doesn’t have an electric ignition system. This allows the unit to operate during the instance of a power outage. You should always contact a full-service retailer when selecting the most appropriate vent-free gas product for your needs and have the kitchen appliance professionally installed and serviced. All vent-free gas heating equipment sold within the U. S. today, regardless of the size, shape, appearance, heat output, or price, undergoes testing with a rigorous safety standard.
