Looking to Replace Heat pump backup from Oil to Electric
Comments (6)Jojo, I'm just a homeowner - not a pro. That said, I live maybe an hour from Baltimore in Rockville, MD. Last year I replaced my 1980s vintage A/C unit and my 1973 Oil Furnace in my 2100 Sq Ft Colonial home. I did a lot of research, including making a pest of myself here. :-) I ended up getting a Heat Pump and a 80% eff Oil Furnace. I think very few folks here would advocate installing an oil furnace in new construction if, say, gas were available. Also, staged electric backup to a heat pump in a new installation may be appealing, depending on climate. My new heat pump is much more effective in keeping my house cool during the summer and also it is much more efficient and thus uses less electricity during those summer months. Being a heat pump, I now have the option of using the heat pump to heat during the winter as opposed to using oil. (I use oil only when the outside temp is below 30 degrees.) My electric usage during the winter is down a lot from previous years, and with the mild winter so far I have used less than 50 gallons of oil. Some expenses that I would have incurred if I had changed from oil to staged electric as the heating backup include: 1) Increasing my electric service to accommodate an additional 15Kw of load. 2) Running the electric cabling needed to deliver the 15Kw. 3) Remove the basement oil tank and contents in an environmentally safe manner per local code. I have absolutely no regrets with my decision to keep oil as a backup - either comfort wise or economics wise. Again if I were building a new home I would hope for a heat pump with gas or electric as backup, depending on climate. PS Gas is/was not available at my location....See MoreBaseboard heating
Comments (3)1. Yes. 2. Probably. I would, and have. It doesn't make any difference when you plan to use the heaters; they should be considered fixed loads that may operate continuously....See MoreConverting 2 zones of electric (and heat) from a multi family
Comments (2)I'd get an estimate from an electrician to combine the two services into one. You probably can turn one of the panels into a sub-panel, fed from the other. You might need to upgrade the service on the main panel to handle the entire house. Once you have the estimate, compare the cost with the monthly additional cost of maintaining two separate services. It might be a while before this type of upgrade pays for itself. I don't see where there is a heat problem, other than the fact that you obviously have multiple furnaces (one gas, one oil). Assuming that they're in good repair, I'd stick with what you have. I don't see any advantage to going with an all-electric solution....See MoreGas Heat to replace Electric Baseboards
Comments (13)Matching new and newfangled systems to existing homes can be very challenging. All electric homes were typically very well insulated but even that might not be up to today’s standards. Have there been improvements in air sealing and insulation since the home was built? I can see why the hydronic coil might be useful. You don’t have room for a furnace where the existing air handler is, and the the duct system can’t be made to work with a furnace in the basement. There are a couple of problems to consider with the hydrocoil idea. To have a large capacity, hydrocoils need to be big or run hot, your choice. Since you don’t have room for a furnace with the existing AHU, you might not have room for a big hydrocoil either. You might be able to ameliorate this somewhat with more than one coil in the ductwork if it can be fit. Ok what is the problem with a hot hydrocoil? That seems logical after all. It has to be hot to provide heat, right? It boils down to physics if you'll forgive the cheap humor. For anywhere near efficient boiler operation, you need your return water to be below 130 F. Even lower, much lower, is better. Hot water-driven convectors (aluminum fin baseboards) also need relatively hot water, but not nearly as hot as a typical hydrocoil in an AHU. Toe-kick heaters are hydrocoils. Radiant floor heat can use very low temp water and are a good match for condensing boilers. Cast iron radiators are pretty good too, falling between the convectors and radiant floor heat. You can run them all from one boiler as well as domestic hot water (and melt the snow on your driveway if you want) and it can all be done with upwards of 95% combustion efficiency with skillful design. That is easy with a new building, but you have to be somewhat lucky with an existing home. You also have to know a lot of stuff yourself or have a very good installer. With a boiler in the basement, you could run the hydrocoil and install baseboard close by in the basement in a separate zone. My only caveat there is that small zones can be a problem without a buffer to keep the boiler from short cycling. Maybe efficiency of the boiler is not your top concern. After all, you are going from electricity as fuel to nat gas. The difference between boilers burning at 82 and 98% might not be a big deal. Just don’t let someone install a high efficiency boiler that can’t take advantage of that design because you can’t both run it at low water temps and keep your house warm. It won’t work very well. Note that in less than the coldest weather if the system is set up right, you can still run in an efficient mode with lower water temps, just not for as much of the time. If a modulating/condensing boiler is dropped into a system where it is snapping on and off a lot and can’t condense, it will be neither efficient nor last long. They are not built for that and since they cost more, even a bigger waste of money right from the start....See MoreBrewbeer
