But get some price quotes. I wasn't impressed with the value.
You can get a 3 pass cast iron boiler, stsinless steel indirect and riello burner for less then a System 2000.

    choosing a new boiler

    I'm a homeowner and just found this great discusssion site. We need to replace our boiler after 25 years. The old one is oil fired tankless coil type domestic hot water supply. (Finned baseboard heat) It was OK when new, but inadequate as it aged and we had three teenagers taking showers. Now our family is down to three. Is there a good combination boiler that will give 5 gpm of hot water? I would like to keep the boiler temp less than 180F and get 115F hot water. Everybody likes the indirect tank option, but think it's more than we need for the extra $1000.

    Bite the bullet.................

    Any oil fired three pass boilers with in-direct water heater will save you money compared to a pin boiler w/ tankless. Outdoor reset and priory controls will save even more with today’s energy costs. Forgot to mention you will also have plenty of hot water for showers, dishwasher and maybe clothes washer all at the same time. As far as lower temps, it’s all in the stand by lost which makes in-directs the way to go. John@Reliable

    I agree with John. The investment you make in your new heating system will go a LONG way in saving you money and energy. Take advantage of the modern technology and put science to work.

    Viessmann, Buderus, System 2000, as well as others take advantage of modern technology. I'd consider focusing your research on that kind of equipment.

    concur with the advice you've been given. However,if you are set on a coil,Dynatherm is probably the way to go,they put out a lot of DHW and horizontal tubed

    i like the Triangle tube Deltas....

    they have a tank in tank designe, as the fresh water comes in it helps clean the tank. the appliance has a low water cut-off, anti scald devise and there are quite a few BTU's available for heating.

    brand recommendations

    I looked at the System 2000 website and they make some impressive claims. Does anybody know how they compare with old timers like Weil Mclain?

    the system 2000's have been here for

    over 25 years...almost 30 come to think about it...

    that is not exactly New Technology.

    that Triangle tube i was babbling about really is a good value.

    Pay more get more with indirect. Don't forget the warranty with indirects.

    Delta Elite great product to consider. Watch the flue height, unless direct vent.

    Look at Buderus great product with outdoor reset it can pay for itself it no time. Choose Riello for oil.

    Ditto the indirect, one thing to consider if you thought about it are the direct oil fired water heaters like the big Bock units...Don't ....I like the triangle more and more, cost, instalation, long life and relativly fewer problems than others. you can't go wrong with any of the oil things you have or have been mentioned to date. The R brand is especially nice, but a caution is how far away are factory trained installers if they are close then great but distance is not a plus come parts time or knowlege wise, they don't go wrong all that often and many swear by them but if someting does go awary then you will need knowlege only avalable from the factory!

    I don't know anything about

    the indirects, but I do know about pin boilers and tankless DHW heaters... 2 gal a day in the summer with nothing else making use of the heat.

    60 X $2.00 / gal ( or more ) = 120 bucks a month for hot water.... My entire electric bill for Feb. including hot water = $102.08

    Now I'm no genius, but...

    I wonder if electric heat isn't becoming more of a viable alternative?

    After I wrote the above post

    I got to thinking ... I don't believe that info is correct.

    I don't think it was 2 gal a day, but now I don't remember what it was. I think it was a little over a gallon a day.

    They say the memory is the second thing to go.

    Sorry for the mis-information... but I still don't think the tankless are economical. I don't use mine.
