Installing a simple ductwork heating system for beginners.

This part of my site will teach a little about ductwork heating, but it will also cover a few other areas of heating like baseboard heaters, which are really easy to install. Wood stoves, for those who have wood resources. Furnaces and central heating, which is the most common heating methods. And radiant heat floor systems which are gaining popularity.

Most of the modern cooling systems are built in or close to the heating system to share the ductwork heating system. So cooling is sort of a part of this too.

This can be a part of a diy heating home plan because it’s easy to do.

Let’s start off with voltage requirements for Electric Heating. It is almost always a 240-volt circuit. It runs cheaper that way. You will need to run a dedicated line to the furnace.

The amperage will depend on the specifications of the furnace. Most residential furnaces will be wired with 10-gauge Romex. The fuse at the breaker will depend on the specs, but will probably be at least a 30-amp, 240-volt breaker.

Some Electrical codes make you run 10-3 Romex so you can have 2 hot lines (black and red) and a white neutral line that runs to ground, or in other words goes back to the neutral bus bar in the breaker panel.

The furnaces are quite easy to install and the ductwork heating system is just a manner of taping the ducts together and running them to all the heat vents throughout the house.

A simple way to heat our homes is by using wall heaters or baseboard heaters. Every home heating plan should have at least one of these heaters integrated in.

These are easy to install and are much more economical than they ever have been. You can run 12 or 10-gauge Romex for the circuit runs. I prefer 10-gauge cable because it won’t get as hot in the walls.

Baseboard electrical heater install wall units have a thermostat wire that you can plug into a thermostat or you can just set the knob on the desired temperature and they will activate with the temperature.

These circuits are usually on 30-amp, 240-volt breakers.

You can usually have 3 or 4 heaters on one circuit. These heaters come in different sizes. Some use BTU’s as a measurement of heated space. You can usually go by wattage for an accurate idea of what size of room it will heat.

1,000 to 2,000 Watts——-Small Room (10X10)

2,000 to 3,000 Watts——-Average size Room (12X16)

3,000 Watts and higher—–Large Rooms (15X20)

There are several other options for heating that are very popular. Floor heating is becoming widely used and the installation has become easier.

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.

Thank you,

I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
