Thermo-Dynamics Side-Wall Direct Venting

There was a time when all you had to do was burn fuel and heat your home. We weren’t concerned with efficiency or costs. But, now we are. The technology has improved enormously even in the last 10 years. Thermo-Dynamics has led that enormous improvement with constant improvements to our designs.

Why Our Boilers Are So Much Better

  1. DIRECT VENTING – Thermo-Dynamics pioneered side-wall direct venting.
  2. NEW CONSTRUCTION – it saves the homeowner significant first dollars by eliminating the need of a chimney altogether.
  3. ELECTRIC HEAT CONVERSIONS – the compact design and small footprint allow installations even in closets and alcoves. No need for a separate utility room.
  4. SYSTEM UPGRADE – allows installation of high efficiency boilers in spite of poor chimney draft. All three applications use outside air for combustion which saves you money!
  5. LOW MASS LMD SERIES – This sounds like physics and it is! The low mass of both the boiler and the internal water content means it has fast recovery and less heat loss during off-cycle idle periods. Coupled with an indirect water heater, it provides abundant hot water for hot tubs, multiple bath rooms, and appliances for today’s contemporary life styles. Combination Boiler with Domestic Hot Water Built In-
  6. CWL-DV SERIES – This is a compact appliance which is only 29-1/2″ high and listed for “close clearance”. It can be installed touching walls on the sides substantially reducing the space needed. Oval tube design means greater heat transfer and efficient use of fuel.
  7. HT-DVL SERIES – A leader in appliances with built in hot water coils, with its 30 gallon water content and its “stingy” triple-pass heat exchanger provides residential heat and hot water. Both units boast AFUE ratings in the mid-80% range according to DOE test standards as published by the Federal Trade Commission.
