    Default Need new water heater option

    I currently have a oil fired Peerless boiler that heats a two story 1680sqft home and provides hot water via an Amtrol boiler mate. I belive its an indirect hot water heater system. The boiler mate has started to leak just after the 6 yr mark no warrantee left. To replace the tank will cost $1500 to $2800 depending on which type of tank I go with. However my concern has been the cost of replacing it and also the current cost of oil at $3.60 gal. Am I better off going with a high efficency electric water heater? Only two of us in the home. Indirect or electric to save? I figure I burn at least 1 gallon of oil a day to heat the water (maybe a little less) but $3.60 x 30days= $108 a month for hot water.

    I would go with electric if I were you, and go with a conventional 40 gallon tank, but get a high end model that is well insulated. I would also suggest that you buy it from a big box store and arrange installation through them. If you hire a contractor first, they are likely to install a cheap model.

    The cost to operate an electric should be about the same as your oil fired unit, bit it should be a lot cheaper to have an electric installed. One thing that may be a problem will be if you have an adequate 220VAC circuit where the heater is going to go and if you don't, how much will it cost to have it run.

    I question your statement that your burning 1 gal. per day to make hot water. Your oil burner is firing about .75 gal per hr. That would mean that for hot water it's running for more then 1 hr. per day just for hot water.

    John. I'm not sure if that number is correct. That is based on some conversations with industry professionals (plumbers, HVAC) and based on info from some other forums. Im not well versed in this and that is why Im searching for more info and feedback before making a decision. One thing I know is that I'm burning thru oil quite fast. At least in the last few years. I have programable stats (two zones) and I keep the heat at a minimum 67, 68. The only other thing that can be eating the fuel is the water heater. The home is 7yrs old and last year I had more blown insulation added to the attic, air sealed and all. So that is why I'm questioning this.

    I agree with John.

    I have almost the same sq.footage in my house and also live in the Northeast; I've had an Amtrol Boilermate for the past 10 years and I love it; during the heating season, it is hard to determine how much oil is spent separately on DHW and heating the house, because the boiler heats up the water to go thru the radiators/baseboard, & that same hot water goes thru the coiled piping inside the Amtrol HWH.

    There is a SIX YEAR warranty on Amtrol products, so I don't know where you got the info on just a 3 year warranty---contact Amtrol directly at www.amtrol.com to formally file your claim.

    There are 30 gallon indirect hot water heaters (IHWHs) available that would result in lower heating bills, if you just have a family of 2; I took some steps to cut down on my oil bill---5 years ago I was burning 1100 gal./heating season---i had an insulation co. come over to blow in some cellulose insulation in all the exterior walls & top off the amount in the attic---this in combination with having dual-pane vinyl storm windows installed worked wonders-----my annual oil usage dropped from 1100 gal to 600 gal/heating season; I also zoned off the 2nd floor from the 1st floor with separate zone valves & rented out the 2nd floor apt.; the added income is a plus, but the tax write-off for repairs & supplies to the rented half is a real money-saver.

    I would say if you are not sure if you have insulation in all exterior walls of the house, get it checked out---blown in insulation is very cheap & it saves on cooling bills in the summer, as well as greatly reduces oil consumption in the winter.

    You didn't say if natural gas is available in your neighborhood yet---if you have the option, switching to NG would also be a real moneysaver.

    The Boiler Mate was installed 6.5 years ago when the house was built. The warranty ran out in September of this year. Is it me or do these things know to break right after the warrantee is up. As for the insulation I have R 15 on the outside walls and as I stated I had blown insulation added to the attic last year as well as air sealed. I have two zones also, but as you stated not sure how to calculate what amount of oil is used for water heating vs heating the home.

    Thank you for the response Keith. However I'm looking for the overall long term savings. I have been told and read some places that the indirect offers the best recovery and most hot water of any system. But when its being done by oil and at the current price it is expensive. If it's going to cost me the same to run electric as an indirect should I stay with the indirect to get more hot water when I need it?
