In some cases, you may want to consult with an architect or a building conservator with knowledge of heritage house conservation and in others, an engineer, before undertaking work that may compromise the structure. So, make sure you have door seals on all your doors. Moisture can cause concrete to crumble, wood to rot and paint to peel; it can also damage plaster, ruin carpets and encourage mould growth. Zone heating combats this by reducing air flow to areas that are approaching or are at optimal levels, allowing more of the warm air to be sent towards the zones in need. The air barrier must be continuous and well sealed. Refer to the Planning energy efficiency renovations for your home section of our website. The combination of heat rising from the stove causes the fan blade to rotate and direct a gentle draft of warm air in a specific direction. This will enable you to regulate how much heat you want in each area of the home wherever the stove is situated. Typically, the requirement is to have one detector located near the furnace or appliance and one detector in each bedroom area. Get some plastic covering the interior of all your windows. Control of moisture in all its forms is critical in making homes durable and comfortable. It can originate from the outside of a building as surface runoff, ground water, ice, snow, rain or fog. When the temperature begins to drop and cool air starts to enter the house through small openings, curtains can be a great way to mitigate the infiltration of cold air. How can I make my home more energy-efficient? Condensation is more likely to occur in humid areas such as the kitchen, bathroom and some basements and crawl spaces. Insulation divides the air space into many small pockets of still air, inhibiting heat transfer by convection. I have enjoyed the service for 2 years now. At the same time, the insulation material reduces radiation across the space. Each zone represents an area that experiences a similar number of heating degree-days. Ventilation can occur naturally, aided by the stack effect and open windows, or mechanically, with the use of a fan, or series of fans, that pull air in or out of the house. Polyethylene sheets and foil-backed gypsum drywall can combine these functions. Uncontrolled airflow (i.e. These steps may be necessary in houses where extensive retrofit work has already been done. Many people believe that because hot air rises, most heat loss will be through the ceiling. And you’ll need a chimney if your house doesn’t already have one. This chapter explains how building science principles can help you control the flow of heat, air and moisture, and why you must consider these factors together. It reduces heat loss by preventing air from passing in and out through the envelope and protects the insulation and structure from moisture damage. Depending on where the heater is and what else is going on, it could reverse flow I suppose. The heat they trap within can also be transferred to the entering air, allow for it to circulate at a warmer temperature. First, most older houses are so loosely built that, even after extensive air-leakage control work, enough air will still come in to provide ventilation. What this does is cause a convection-reaction that forces the hot air away from the heat source. Any cold water in the recirculation line is returned to the heater. If you've got a central air-conditioning system, you might run it in "Fan Only" mode just to get the air in the house circulating. The chimney should be vented out horizontally through the wall about 12 to 24 inches above the stove. The heat-powered fan. I’m a happy customer. When insulation is added, the building exterior becomes much colder. A check valve must be installed in the line to ensure hot water only goes in one direction. Make sure your ceiling fans rotate clockwise so they pull cool air up off the floor and push warm air down. In any event, it is advisable to consult with your local building authorities about planned upgrades. 1. The air barrier, when located on the exterior, may also act as part of the drainage plane.

RSI 3.52 batt [R-20] as purchased). A zoned heating system allows you to optimize the flow of warm and cool air within your house by separating your home into different areas that are controlled by different thermostats. Windows, doors, and your attic are the greatest sources of heat loss. In poorly air sealed homes, uncontrolled airflow brings colder, drier air indoors and forces the warm, moist air out through openings in the upper walls and attic. The air can then no longer hold all the water vapour and some condenses out onto the surface of the window. polyethylene, drywall or plaster – when used for large interior surfaces such as walls and ceilings, windows, doors, hatches, vent dampers and any components that close an opening in the envelope, structural parts of the building in some cases, such as the sill plate or rim joist. Controlling airflow prevents uncontrolled air leakage through the building envelope, provides for fresh air supply and the exhaust of stale air, and provides draft and combustion air for fuel-burning appliances. In addition to limiting circulation, the obstruction also damages the furniture as well. If air movement between inside and outside is accidental, we call it infiltration. If the window is extremely cold, the condensation will appear as frost. The sun is a huge thermal reactor about 93 million miles away in space, and neither conduction nor convection can produce any of the energy that arrives to Earth through the vacuum of space.
