Hello All,
I'm in the process of making a decision on purchasing my first OWB and found this site extremely helpful. It seems there are a lot of really informed members here so I decided to solicit some thoughts and feedback to ensure I'm on the right path and to cut through some of the marketing hype and hear from real users - good, bad, and otherwise. I would really appreciate your candid feedback, but kindly request that it's informed by personal experience or some sort of expertise related to OWBs - not simply brand loyalty, i.e. I love "insert manufacturer" because "they're awesome"....even if it's from members affiliated with a manufacturer.
Requirements: So, I have done a few weeks of extensive research and believe an OWB is ideally suited to my needs here in Virginia. I'm looking to heat an approximately 4,900 square foot modern farm-style home that is well insulated, and a detached workshop of approximately 1,000 sqft. with an apartment above that is approximately 750sqft. Both are currently heated by oil using two separate boilers. The home is three levels - the first two floors have radiant in-floor heating (including the home's attached garage) and the third level has a couple of radiators. The detached workshop has radiant in-floor heating in the shop and the apartment above utilizes radiators - it's also well insulated. I would also like the OWB to heat two hot water tanks - one for the house and another for the detached garage/apartment. Given those requirements and the big $ to heat with oil, it seems like an OWB would be an excellent option. My general estimate is that I'll recoup the costs of the OWB, the install and ancillary equipment (minus any wood expenditures) within 3-4 years. What really sold me was the fact that I can set this up whereby if, for whatever reason, the OWB runs out of wood, the oil simply kicks in and maintains temp....as I do travel periodically. Lastly, I would love to possibly use an OWB to heat a future pool or a hottub, and an OWB seems like a really efficient way to do so.
As a total aside, I am now trying to convince a buddy of mine that he too needs to look into an OWB....he has a smaller home but a separate, large hangar that eats $ in the winter to heat with propane and electric - so there's the chance of looking at a twofer.
Anyway.....after reviewing many manufacturers specs and endless hours online, I've sort of narrowed it down to three. These are the Portage and Main EGR 250, the Heatmaster G400, and the Central Boiler Classic Edge 750. However, I'm still open to input if I'm missing something, and, realistically, I'm really leaning away from the EGR250 as I understand it's significantly more expensive. I'll detail my thoughts on pros/cons below, and welcome your input if I'm off base or if there's more I should be considering.
Portage and Main: What attracted me to them is that they appear well made, and the company appears to operate with excellent ethics and integrity which means a LOT. I was also intrigued by the design of the EGR250 and the fact that the heat exchangers travel horizontally and vertically. I also really like the use of the refractory brick, as I believe that would prevent corrosion and maintain heat but could crack. However when I look at the EPA efficiency, it did not appear more efficient than the G400 or Classic Edge 750 which I would have to see to justify the higher price. The cons for me was that I'm on the East coast and don't know how prevalent P&M is or how that would impact support, particularly as I'm in Virginia. Having said that, I only read excellent things about the company and their commitment to the customer. I also don't love the metal hangers in the firebox - my lay person view is that these may need to be replaced at some point which means $$ - but i could be way off. Either way, this has dropped on my list if I'm looking at over $15k compared to it's equally efficient competitors coming in at $10-12K. If I lived in a colder environ, I may view things differently.
Central Boiler Classic Edge 750: So, this company clearly appears to be large with a vast supplier network and many units in the field, for better or worse. What I like is that my understanding is that this is the best priced and I would worry less about having a good dealer in my area. I have to say that I'm also intrigued with the WIFI option to monitor the OWB from afar or from inside the house. This may very well be a gimmick, but tracking efficiency in real time and with solid data does seem appealing. I was also impressed with the EPA numbers. I have mixed feelings on the spray foam insulation, and do see that they offer a stainless steel version as well; but I do worry about life expectancy. The big negative for me is that there are "only" three supply/return ports - I love the option to expand if needed. Anyway, seems like it would have the BTUs for the job and would be a great option.
HeatMaster G400: For whatever reason I wasn't following the G400 too closely until reviewing the EPA stats and this really popped out. I then looked into it further and have to say I'm probably leaning towards the G400. What I like are the four supply/return ports, the efficiency numbers, and the build quality looks very good - the stainless is appealing, and the lifetime warranty. The reviews seem to indicate that it eats less than dry wood fairly well too. I also like the lever to clean the vertical heat exchangers. I would assume to prefer the P&M horizontal AND vertical exchangers, but the EPA numbers indicate there's no benefits gained over the G400. On the downside, the smoke diverter is slick, but I could see myself (or my wife) forgetting to return this after reloading wood, despite the red button screaming at you. Having said that, if this is 2-3k more than the Central Boiler, can I really justify the cost when the efficiency/BTU numbers are so similar? Lastly, I have to say that I was really impressed with the HeatMaster NorthEastern rep on this site, who appears very engaged on the forums, etc. and very involved with his customers.
My apologies for such a long post, and really appreciate any informed feedback. I'm not looking to make any purchase in the near term, but I have committed to purchasing an OWB and these three seem like great options for my requirements.
