- Shower image by Semfamily from Fotolia.com. A direct vent hot water heater contains a sealed pipe system for intake combustion air and exhaust gases. This creates an air-tight combustion chamber which eliminates backdrafting and improves fuel efficiency. For combustion air, a gas-fired hot water heater draws in outside air or pulls it from inside the house.

- Direct steam injection (DSI) heaters inject. steam directly into the circulating water loop. For processes which return the jacket water. below 212°F (100°C), they achieve 100% heat transfer by using both the sensible and the latent heat of the steam. Above this temperature there is a minimal drop in efficiency. Let us compare the efficiency of an indirect (shell and tube type) heat exchanger to a DSI heater.

Direct Expansion Air Conditioning What It Is. A direct expansion air conditioning (DX) system uses a refrigerant vapour expansion/compression (RVEC) cycle to directly cool the supply air to an occupied space. DX systems (both packaged and split) directly cools the air supplied to the building because the evaporator is in direct contact with the supply air, Expansion refers to the treatment of the refrigerant (a valve reduces its pressure and temperature) prior to it entering the evaporator.

What is a Direct Vent Fireplace? This type of fireplace heats a room without robbing it of oxygen or of the heated air it is providing, while also keeping it free of fumes and combustible materials such as embers or ash. A direct vent fireplace can be a wonderful choice for rooms in which a traditional fireplace is not practical or possible. Aside from providing clean warmth and the cheery glow of real fire, it saves space by allowing furniture to be positioned directly to either side with zero clearance..
