Boilers

Archive for the ‘Wood Boiler’ Category

My house has a 3 flue chimney with one closed off opening to the kitchen for a flue that is not in use. I suppose it was for a wood or coal kitchen range. The chimney rises through my 2 story 1898 home and thru the attic. The other two flues are for the boiler and a fireplace which is never used. . We wonder if a range hood could vent into this flue? Our carpenter worries that it would cause a lot of heat loss. I worry that the old flue might be very dirty.

It would be perfectly fine for you to do this. However, your carpenter is absolutely right. When you are cooking in the winter and start up your hood, it’s going to blow expensive hot air right out of your chimney. All in all, it’s not really worth it unless you live in a very warm climate.

I can’t seem to find any that are free but plenty that are $75 or so. that seems kinda steep when all I really need are a few measurements. I have found most of the parts I need I’m just looking for something that will tell me how big things need to be for my application. Thanks in advance!!

spend sometime on"motherearthnews.com" look around I found a method of heating a small shop in the country with compost and a radiant heat system that is the cheapest heating system ever. im sure you’ll find what you want

Radiant floor heating can be an efficient and energy saving method to produce warmth in the home. Simply put, heat is channeled in the floor to provide a warm and cozy feeling. This type of heating is also called infrared radiation. The system uses the convection principle where the heat rises from the floor by natural circulation of heat.

Typically, there are three different methods of radiant floor heating air, hydronic or water and electric. The particular type of system installed depends upon the individual, available heat sources and of course, the cost. Radiant floor heating can be especially helpful to persons with allergies since the reduction of free flowing air is reduced. Energy efficiency is further increased by the reduction of air loss from air duct systems.

Hydronic heating systems or water-heated systems use hot water to circulate the warmth. The heated water radiant floor heating is considered the most effective and cost efficient of the three most common types of radiant floor heating. The heated water is circulated through piping or tubing placed under the floor. The piping system is attached to a boiler that is used to heat the water. A number of different methods such as gas, wood, or solar power can heat the boiler.

Electric radiant floors are comprised by a matting system placed under the floor surface or by the use of electric cables. More useful over a thick concrete slab, the system can actually store heat and help reduce heating costs. Typically, electricity rates are higher than other utility sources but with the right surface area, electric heat can actually save heating costs and energy efficiency.

Air heated systems deliver the heat by the circulation of hot air. This system can use various different methods to heat the air such as solar power. The best heating time for solar powered heat is during the day. Air heated radiant floor systems are not as cost efficient since air does not hold heat very well. This type of radiant floor heating is not widely used because of the cost and effectiveness of the heating system.

The total cost of each system can be quite daunting at first glance. This is a case where you have to spend money to save money. The total heated area, location and method used will determine which type of radiant floor heat will be the most cost effective and energy efficient for a particular homeowner. Many homeowners and contractors will use floor heat for new editions, remodeling and new home repair.

Energy efficient, earth friendly and easy on the monthly utility bills make radiant floor heating a wise choice for the homeowner. Since less heat is lost, and dust and other pollens are reduced from the typical duct system, radiant floor heating becomes even more of a home?s asset.
