I’m finding that word can get around. Like the guy who likes the veggies everyone else hates, when you can heat with wood that others can not use, you find your plate filling up!
With this in mind, I’d like to take a minute to analyze the cost of installing and operating a Radiant Masonry Heater in any home.
We’ll assume a 2,000 square foot home in the Northeastern US. A masonry heater has a 50 – 80 year run before any major servicing is required. You might spend 300 dollars on a firebox rebuild depending on how hard you push the unit and what construction methods were used 10-15 years post installation.
There’s a number of benefits of a Radiant Heater that can’t be costed out. What’s it worth to have a healthier, dust free, more pleasant radiant heat source creating a cozy family gathering spot in your home?
What price do you put on cleanliness of burn, local fuel sourcing, carbon neutrality, and ambience?
If those things sound good to you, remember them as you read the prices below, because the options we’re comparing to offer far less of those things.
Cost of installation:
Assumptions: chimney existing, foundation to be built (included in cost)
You can get a basic installed radiant masonry heater that will heat 2,000 square feet for 13,000.
|COST OF OWNERSHIP||install cost||longevity||annual fuel cost*||operating cost|
|(mean)||(years)||2,000 square feet||annually|
|Boiler fired radiant floor system||17,000||35||3116||$3,601.71|
|Masonry Heater (premium hardwood)||13,000||80||900||$1,062.50|
|Masonry Heater (free fuel)||13,000||80||0||$162.50|
|* Fuel cost based on average per household oil consumption in Northeastern US|
THE BACKGROUND ON THE TABLE:
MIT estimates* a 20 year average life for a furnace and heat pump. A boiler, they say, will go 35.
A new boiler might cost $5,000 to $8,000, or 228.57 per year.
A new furnace might cost $ 3500 to $4500, or 225 per year.
A new heat pump might cost $5000 to $12,000, or 600 per year.
Please note that these prices do not include any duct work, piping, or (in the case of heat pumps) collection system buried in the ground outside your home.
APPLES AND APPLES:
For a more accurate comparison, let’s consider an installed radiant floor system.
Boiler: $5,000 – $8,000.
Pumps, plumbing and concrete pour: $8,000 – $14,000.
Total installed price for a radiant floor system: $13,000-$22,000.
Now, I can explain how the radiant heat that a masonry heater gives is better than the radiant floor for most people, (see: http://radiantstoves.com/why-point-source-radiant/) but I don’t need to: A radiant masonry heater actually costs less to install than the average radiant floor system!
If you’re like most people, you don’t save up for your next boiler each year starting from the moment you installed the last one. I’m figuring you might start saving five years before the boiler will need to be replaced. If your boiler is 5 years from replacement, you’re 5 years away from a $5,000 to $8,000 bill, and since you need to stay warm while you save, you’ll need to put away $4,716 each year to stay warm while you save up to replace your boiler!
Maybe in the same way that you’re not going to put X dollars in the account each month for 35 years to save for the boiler, you’re not planning on an 80 year payback cycle for your masonry heater. Me neither! Check this out:
|Operating cost to pay off initial investment over different time periods.|
|initial outlay||years||annual fuel cost||total annual cost of ownership.|
|20 years||Masonry Heater (premium hardwood)||13,000||20||900||$1,550.00|
|Masonry Heater (free fuel)||13,000||20||0||$650.00|
|10 years||Masonry Heater (premium hardwood)||13,000||10||900||$2,200.00|
|Masonry Heater (free fuel)||13,000||10||0||$1,300.00|
|5 years||Masonry Heater (premium hardwood)||13,000||5||900||$3,500.00|
|Masonry Heater (free fuel)||13,000||5||0||$2,600.00|
If you pay the same amount each year as you would to operate a simple boiler system, you’ll have paid off the Radiant Masonry Heater in 5 years!
LIVING THE GOOD LIFE
Where will you be in five years? I know that I want to be done paying off my heating system and investing my energies in other things. You could be living in all the warmth of point source radiant heat, and not be looking at another 30 years of paying for your heat source.
*** All my units come with a replacable liner for the firebox which can be installed easily.
