New furnace

Well looks like we are going with a New electric furnace. I voted for a wood burner but I got out voted.


I have 2 ?'s We would like to have a service tech come and give the old furnace a look over to give us some idea if a new furnace will help. Is this something we should do or would it be a waste of money?

What should we consider we buying a new furnace? Kw,btu's,size brand etc? Again the house is 900-1000 sq ft and furnance would sit in a confined space (almost like a closet)

The old one is 17 kw and 54,000 btu;s Already look at a few online and talk with a couple sales people. Answer I have got so far are I could go with a 34,000 btu
The old furnace may work fine but is to old to do the job of heating the home (it is 12 years old)

I am going be in no hurry to replace it and I will do the work my self.

Thanks

Id want no less than 15kw. If your going to replace the old unit why get someone to look at it?

The ONLY method of sizing a furnace that is reliable is the Manual J heat loss. I had a house of about the same size in a community just north of Seattle and a 10kW electric furnace heated it just fine.

I can't see how having it looked at will change anything. Electric is not like gas..... there's nothing going up the chimney so there really isn't an efficiency issue to consider. Every dollar you spend on electric heat is being released in the house.

Basically you're changing your furnace for something more reliable due to its age...... right ?

The 1 that I was quoted was a 10 kw 34.000 btu. I think I should stay with somewhere between 15-17 kw and 52,000 -56,000 btu's

The service tech idea wasn't mine I believe my wife wanted some sort of assurance that spending money on a new furnace will solve are issue. We are looking at somewhere in the range of $450-$560 for a new one.


The reason we are wanting to replace the furnace is heating cost. Over the last 2 winters are bill has increase like crazy. For the winter months are bills are ranging from $400 -$525 a month. In summer with whole house air are bill ranges from$ 160-$220 a month

I don't think spending money on a new electric furnace is going to save you any money.
Improving insulation will save you money.
Sealing the house better will save you money.

You'd be better off spending the money on a wood burner.

Ok...like emergency heat in a heat pump? Just never heard of it. Seems like NG or LPG would be cheaper...but what do I know.
