Best Way To Replace Wood Boiler Heating System In A Slab Foundation House?
I'M Interested In Buying A House That Has A Slab Foundation. The House Is In Maine, So Temperatures Get Very Cold In The Winter And Power Outages Occur At Least A Couple Times A Year. The Only Obvious Problem With The House Is The Heating System(S). The Main Heating System Is A Wood Boiler, With A Supplemental Propane Heater, And A Couple Smaller Electrical Heaters Throughout The House. There Is Only 1 Direct Vent That Blows Heated Air Into The House From The Boiler In The Garage. It'S A Pretty Big House (~3600 Sq Ft), So I'M Sure The Supplemental Sources Would Need To Be Used Regularly In The Winter. Although The Wood Boiler Would Be Great During A Power Outage, I Don'T Like The Idea Of Having To Burn Wood All The Time, Especially Since It Needs To Be Tended Constantly. I'Ve Looked Into Radiant Heating, But My Understanding Is That The Floor Would Need To Be Torn Apart, And Would End Up Being Higher Which Would Complicate Other Things. The House Is Bank-Owned So There Won'T Be Any Negotiating Of Such Details, But It Is Very Reasonably Priced Based On The Size Of The House And Property (~100,000 Below The Real Value) Because It'S Been On The Market So Long. So, My Question Is, What Would Be The Best Alternative Heating System That Could Be Installed In A Slab Foundation House Without Spending A Fortune And With Minimal Demolition? Thanks For Any Suggestions/Insight!

First you have to understand that "heating system" is a catch all phrase that includes some major divisions. The first is that it can be a central system or a non-central system.

If all the heat is produced in one place it is a central system. Furnaces and boilers are the central heating plant of most central systems. The other half is the heat distribution system. Furnaces are for forced air heat distribution systems and boilers are for hot water heat distribution systems. This includes the duct-work or piping and radiators or the floor work of a hydronic radiant system. The heating plant can be relatively inexpensive while the heating distribution system is very costly.

A completely different approach is non-central system. This could be the old fashioned fireplace in every room or baseboard electric radiators or a new system is to use ductless split AC combined with a heat pump function.

Non central systems an in built advantage of zoning so you can turn have different areas with their own temperature. A central system can have the same functionality but it will add to the cost and complexity of the system.

The "fuel" to be used is an entirely separate issue. Central systems tent to include the options of propane, natural gas, oil but also geothermal (ground source heat pump), air source heat pump and even wood.

Non central systems tend to use electricity, but gas and wood heaters in rooms have been used in the past.

Electricity can be used in radiant in the floor systems, radiant wall and ceiling hung panels, resistant radiators and heat pumps. Because the only distribution that is need is wiring and does not need an exhaust system it represents the least amount of reconstruction to a home. It would also likely be the cheapest installation. But these factors must be balanced against the cost of electricity in your area, the potential savings with zoning and how effective heat pumps might be in your area. If at any time you were considering installing PV solar panels concurrently using electricity for heating is likely to increase your ROI.

If you wanted to investigate options using Solar Heating, the cheapest system would only attempt supplemental heating using Hot Air Solar panels and forced hot air with little or no heat storage capability. The best heat storage in decreasing order would be phase change materials, water and masonry. This might be an option if you have a good southern exposure. But with any solar option heating is only economical only after funding conservation techniques.

There are many other options including your present hybrid system. In the final analysis all such advice is dependent upon local conditions and it is impossible say if any generalizations will fit your particular circumstances. You might want to consult with a local HVAC contractor, an electrical heating contractor or an alternative heating specialist. A good local contractor will ask a lot of questions to understand what you are trying to achieve to determine the option that is the best fit.

Which Costs More To Run? Heat Or Air Conditioning?

If you are not talking electric heat then air conditioning is usually the worse energy hog.

You also have to consider climates different than the norm. If you live in a cold area that doesn't get much summer need for cooling then heat is the worst. If you live in a tropical area with no heat usually needed than air conditioning is the clear winner. My answer was based on a "four-seasons" location where both hot and cold are problems.

Air Conditioning Problem No Cold Air Is Comming Out?
The Air Conditioning In My House Is Not Blowing Any Cold Air Out At All In None Of The Vents. Air Seems To Be Comming Out But Its Just Normal Air. What Is The Problem? What Might Some Of The Problems Be?

There are several causes for your symptoms. With nothing working outside could mean that your breaker is thrown or a fuse is blown. Another thing may be your contactor. Is there a humming in your outside unit? If so, your thermostat is working. Your contactor may be bad or if you live in the South, you may have a fireant problem preventing the contactor from working. Also in this heat you may have a problem with a capacitor. In this heat, I have changed several capacitors this year. Unless you are experienced with electrical circuits. I would suggest you get a serviceman to look at it.
