  • OIL HYDRONIC HEATING IS CHEAPEST – For The “Smart” Consumer

    The assumption is that natural gas heating is historically cheaper than fuel oil, witnessed by the continuing conversion rate of oil to gas. The arguments forwarded are several, most notably that “natural gas (and propane) burn cleaner”, are “less expensive” than oil and therefore “more efficient”. All of these points are true in some context, but what is excluded has become significant to the discussion. Namely, heating system efficiencies and fuel cost differentials are narrowing the gap. Exactly how and by how much are the issues.

    An old New England adage comes to mind: “You can either raise the roof or lower the floor” to gain more space. Applied to heating you increase the efficiency of your appliance or lower the cost of your fuel ….. or do both, as we will contend.

    First, let’s begin by “raising the roof” of heating energy creation efficiency. Here again, hydronic (hot water) boiler efficiencies have increased significantly with AFUE Rating increases of over 10% for gases and half or less that for fuel oil. Good numbers at present are 95% AFUE for gas and 87% AFUE for oil “top end” appliances. More specifically these are Condensing Gas and Triple-Pass Oil Boilers. Now let’s get in a little deeper.

    There are three basic elements in any hydronic heating system:

    1. Heating water (a boiler),
    2. Moving heated water (distribution), then
    3. Heating the environment (radiation).

    The contemporary presumption is that the Boiler DOE %AFUE Rating defines heating system efficiency. This is patently untrue on its face. Distribution and radiation efficiencies must be considered to determine an aggregate value. Radiation by type and deployment also affect distribution configuration and complexity. The ensuing “middle ground” between the boiler and radiation we cynically denote as “The Plumber’s Playground”. Herein appears a relative maze of pipes, fittings, circulators, controls and wiring connecting A to B with artistic “free expression”. Thus that new, “pretty piped”, complex heating system despite saving some fuel is an electrical energy hog and a serviceman’s “friend”.

    A hundred years ago we had the Gravity Hot Water Heating System. It was utterly simple, had no moving parts and was operated by manually regulating a fire under the boiler. Powered coal stokers, oil or gas burners were later added with a room thermostat for automatic heating. It was abandoned upon introduction of the hot water circulator and zone valves for installation and operational flexibility and remains with improvements to date. However the natural (gravity) convection attributes of yore are present in degree within “modern” hydronic systems and necessarily controlled with valving.

    Recent introduction of the Delta-T ECM Hydronic Circulator prompted and enabled us to effectively recreate a Neo-Gravity Hydronic Heating Appliance. Functionally it is akin to “putting an ‘Automatic Transmission’ on a Boiler”. Hydronic distribution energy is typically reduced by over 90% of contemporaries. Convective flow is finitely controlled by the Delta-T ECM Circulator like “paddling a canoe with the current” ….. virtually effortless! Coupling to a high-mass, cast-iron boiler to reduce burner cycling and system operating temperature increases boiler AFUE substantially, depending upon the site radiation and heating demands. These claims are substantiated within our U.S.P.T.O. Patent Submission, now affirmed by a recent Notice of Allowance. Canada to follow. Check out our website www.BoilersOnDemand.com for details.

    So, first upgrade your aging, less efficient boiler to a post-modern, high-mass, delta-t ecm distribution appliance, such as ours.

    Second, let’s “lower the floor” by changing your fuel oil buying habits! The “dirty little secret” is that you have options, many options. You don’t just keep buying from “Good Old Joe” because he’s nice and “takes good care of me”. Or pick an oil dealer out of the phone book, your neighbor recommends, or whatever. Not unlike automobile “gas station hopping” the oil dealers have a back door pricing system too, called Consumer Fuel Oil Co-Operatives. They typically aggregate fuel demands of their memberships and solicit seasonal quotations for heating fuel. To give a comparison, we and our participating customers have realized a 25 to 40% reduction over retail pricing in our area (S.W.N.H.) throughout this 2019-2020 Heating Season, for a $25 Annual Fee! Smarten up folks!

    Now, let’s dispel the notion that natural gas fuel is cheaper than oil, using our one-two strategy as detailed above.

    All heating fuels are rated by their “Cost Per Million BTU” as displayed in the NH Climate Audit Heating Cost Calculator, our personal choice of many available. We have used this calculator continuously since 2016 during our appliance development. In all but one winter cycle oil has been a cheaper heating fuel than natural gas. Oil has also eclipsed all other fuels listed for the past two years. This apparent natural gas discrepancy with oil must be first be explained.

    Natural gas and electricity are “distributed” fuels, i.e. they are necessarily delivered through pipes or wires to the point of use. Distribution and service charges are necessarily applied to these fuels, regulated by a State Utilities Commission. Therefore your actual bill is fuel cost plus delivery charges. Dividing the fuel cost into your total bill defines your Service Burden, expressed as multiplier of 1.x to 2.x. Our local multiplier is typically just over 2 at present. Therefore the Natural Gas Cost Per Million BTU must be multiplied by your Service Burden to obtain your true fuel cost.

    Oil and LP (Propane) on the other hand are liquid “delivered” fuels. You pay upon delivery and they are dropped into your oil or gas tank or as gas bottles in your yard. Similarly with the solid fuels: coal, wood & wood pellets. No additional charges apply. This distinction is very important.

    Playing with the Heating Cost Calculator, let’s load in 87% for oil & 95% for both natural gas & propane per prior. Load in $1.586 per gallon (our current “Co-Op Price) for oil & press “Recalculate”. Now using a side calculator multiply your natural gas price of 8.74 by your Service Burden. If its currently over 1.505 oil wins. (BTW – Pity that poor propane guy!)

    If you want to extend your heating calculator play time, increment the item cost values for coal, wood & wood pellets until you equate each to $13.15 Per MBTU. This is the item pricing equivalent to oil heating. Great stuff to needle your neighbor who’s “saving money” while trying to keep warm with solid fuels. Of course avoid that Old Yankee that cuts all his own wood “for nuthin” and massages his woodpile year ’round. “Heats ya twice, ya know.”

    It must be added that Condensing Gas Appliances are significantly costlier to install with reduced economic lives than cast-iron boilers.

  • Heating Oil vs. Natural Gas Heating Cost Crossover, Again.

    http://oilprice.com/…/Is-This-The-Most-Bearish-Oil-Report-O…

    We are back in the $45/BBL Oil Barrel Price range. As we have prior blogged on our site, #2 Heating Oil is now again the Lowest Cost per Million BTU heating fuel in our region, including Natural Gas. This value is equated via. application of Appliance AFUE Efficiencies of 87% and 95% for oil & gas, respectively.

    For the third concurrent year we have recommended that our clients not purchase “Pre-Pay Heating Oil Contracts” and seek participation in Fuel Buying Clubs/Groups. The current and potential financial benefits are substantial.

    It further appears that this will be a heating season repetitive condition.

  • Oil & Natural Gas as Heating Fuels Equate @ $45/bbl

    By our calculation #2 Heating Oil and Natural Gas equate at an approximate Crude Oil Price per Barrel of $45 in our locale (Northern New England). There are obviously many factors that contribute and must be individually qualified.

    Refer to our prior posting on “The Heating Blog” entitled“Oil Again The Cheap Heat ………….. “for procedural detail. Note that it was published with Oil @ $30/bbl this past January.

    Of particular note is to always delineate between a “Delivered” vs. a “Distributed” Fuel. Whereas you purchase a quantity of fuel upon delivery (Oil, Propane, Wood, Coal, etc.), Natural Gas & Electricity are piped/wired to your location and you necessarily pay “service charges” for their facilities usage, maintenance, profit, etc. Factoring your “distributed fuel” bill is simple. Extract the actual cost for “fuel” and divide it into your total bill. The resulting “factor” of 1.XX must be used to multiply any stated “distributed fuel” cost for an actual one. Note that this “factor” is always changing and is particularly dramatic when comparing mid-summer and mid winter fuel costs.

    You will note that the only two viable heating fuels at present are Natural Gas and #2 Heating Oil. Even our regional “Fuels of Opportunity” as we refer, Cord Wood & Wood Pellets, as purchased are far less economic than generally perceived. Even “free” (self sourced and provided) Cord Wood is arguably uneconomic in use, particularly in our experience when purchasing and servicing Exterior Wood Boilers, a regional fad.

    To achieve an “apples to apples” heating fuel comparison you must use a contemporary appliance cost and performance for the fuels being considered. We use a 95% AFUE average value for Natural Gas & LP (Propane) Appliances and an 87% AFUE for Heating Oil. The Oil vs. Gas Heating Appliance Cost must also  always be considered in calculation, the Gas Appliances being pricier than their Oil equivalents.

    The further unwritten and unstated longevity of Gas vs. Oil Installed Systems must be quantified. You are not going to obtain system life expectancy from your “salesman”, who at best quotes Warranties (if you insist) nor provides maintenance histories. These come from the “old sergeants in the trenches” ….. independent service personnel who daily deal with prior work. Unfortunately they are too few, their voices are seldom heard nor are generally known, overshadowed by the self-anointed trade professionals and marketeers. We talk to the Sergeants …..
