summer DHW options

PostBy: plumber On: Sun Feb 23, 2014 10:15 am

Ok, the wonderful fine of the year is approaching. Warm weather and no heat. I'm looking into my options of heating my domestic hot water. I can keep the boiler going, convert to oil, or install a heat pump like the Nyle Geyser.
The last two summers I've kept the boiler going on coal. I average 600 lbs per month ( about $97 in these parts) as well as deal with losing Draft and the resulting outfires.
I could switch the boiler over to oil and forget about the boiler until November, but I have no clue how much oil this thing will eat. I can deal with a couple extra dollars for a headache free summer and I know I'll never run out of hot water. My third option is to install a heat pump. If the power company is still offering rebates, that would help the install cost. I know that would be the cheapest way as far as monthly cost, and a cool dry basement would be an added bonus, however, I am concerned about the recovery. So I'm looking for some opinions, and insight from anyone who doesn't burn yea round.

I got the GE Hybrid electric and set it to only make hot water with the heat pump. There's only the two of us here & we never run out. If you have a bunch of people I'm guessing you'd have to tell it to make some "the expensive way". I enjoy the cool(er) and dryer cellar.

The recovery is my biggest concern, I have five people in the house. I'm looking more towards a stand alone unit like the Nyle, as I have a storage tank already. I could always install an additional 40 gallon tank if I really needed it.

Freddy, if you don't mind me asking, what does that heat pump cost you to run. I know it is probably a little more than I'd be at. I know how high CMP electric rates are.

The *Fuel Calculator* here works well for Heat Pumps too...you need to know the COP rating of the unit to adjust the multiplier. (300% 400% Or ???)

I let my electric hot water heater take over for the off season. Runs about $50-60 per month
on the electric bill. Cooler basement.. I would choose that instead of fiddling with coal over the summer.

I save the coal excitement for winter.. Don't wanna get burned out on it by messing with it thru the summer lol. That would dip into beer drinking and grill time.. :lol:

You burn over a 1/4 ton of coal for DHW in the summer months?? Maybe I need to keep a closer eye on mine because I would never believe I burn that much. I use maybe 1 to 2 five gallon buckets a week and empty the ash pan once in a week, roughly. I always figured going to electric or switching it over to my oil boiler would be way more expensive and not worth it... though the coal system maintenance (ashes, loading hopper, etc, etc) in the summer is a total PITA.

One benefit of burning in the summer time is the boiler stays dry and wont rust. I know some guys use this time to do a thorough cleanout of the combustion chamber and then hang a light bulb to keep it warm.

That's the flipside. A hot boiler is a happy boiler. One of the things making me consider burning oil.

I would pickle the boilers and install the GE -- only because the warranty is better
yes the other hybrid is divorced from the tank so the tank is expendable but that's me and I am a simple figment of the public internet.

I have a Boilermate hooked up to the coal boiler, and I'm only using about 400lbs a month during the summer, max.

I don't know! I have solar panels & they make enough to power my whole house in the summer.

CMP is southern Maine...we have "Emira" (Bangor Hydro's new name). $.178 per KWH.....but that's going up pretty soon.
