You should have a top-side drain valve which can be opened to allow water to come out and for stabilizer chemicals to be added. Your steam heat may not be that inefficient!īack when I was having my boilers professionally serviced (see my other post for why I stopped paying for servicing) I had a more experienced gentleman show me the proper procedure for skimming the boiler. Taking into account the current rates, the heating part of my electrical bill is about $300. Typical COP is around 2 in the winter.įor a reference point, I used 1200 kWh to keep ~ 2000sqft at 70 degrees in November with my air source heat pumps. With the current ~$0.3/ kWh including delivery (your local rate may be different) the heat pump break even point is for a COP of 3 when compared to 80% furnace. Your current rate is $2.25 per therms with ~30 kWh per therms. Now I should probably do that for my electric delivery cost and see how it changed over the last months (unlike you I only have 18 months of data though).īut even then, gas heat is still 30 % cheaper than electric through heat pumps, but the margin may be shrinking. With many towns having a municipal aggregation program it certainly helps offsetting the costs of greedy utility companies. You almost make a good point for having people switch to heat pumps and only use the gas as a backup. Again, I don't know both sides of the coin to this policy but I think we need to have bigger discussion on solutions to the high delivery fees for gas and electricity. This bill doesn't seem to have received much attention but I think something like this may be worth an initiative petition if the our state reps won't do anything about it. Here's an article referencing this bill for more context: There was a bill that would allow for towns to purchase utilities and help with the distribution, but it kept dying in the legislature for a decade. I think the town or state should own the pipes and grids. Municipal utilities don't charge delivery fees and those towns enjoy lower utility prices. And feel free to copy and paste this as your comment if you feel this is worth getting more eyes on. I want this bill to get more exposure here.Monthly cost with supply and delivery breakdown Monthly Gas usage and average temperatures over years I) Monthly Cost - this is my actual bill (delivery + supply) for each month. H) Cost/therm - final cost on your bill, this is is the value that you can multiple your usage to get final amount. G) Deliv/Therm - Cost NG chargers us to deliver the gas to our homes anything above 1 means that particular month in a year was hotter than average and anything bellow 1 means average temp was lower that 10 year average.į) Supply/Therm - Cost of actual gas from supplier i am heating 1400 square feet, steam heating and my thermostat is at constant 71F (24/7)Ī) Columns 13/14 - represent winters, 13/14 means selected months from 2013 to 2014ī) Rows - Months selected from November to AprilĬ) Therms -Unit Measurements of gas usageĭ) AVG temps - these are actual average temp for each month taken from meteorological station at Logan AirportĮ) Actual/Average - This just illustrates deviation from the total average temperature (averaged over last 10 years). I am expecting to pay this year $2250 based on 1000 therms at $2.25/therm. All this current data is based on the annual bill charges for winter (November through April) for the last 10 years.Īs you can see last year was my lowest (869 THERM/USAGE Table) with highest winter bill expense ($1947 - MONTHLY COST Table) even though we had mildest winter in the last 10 years (AVG TEMP Table).ĭelivery portion of the bill has nearly doubled in last 10 years (See Deliv/Therm table). I have posted before my gas usage and cost of heat during the winters. Cost per therm, supply and delivery combined
