gas company offer

Not familiar with that model Burnham and couldn't pull it off their website with the #s you provided, but remember one thing.....the main objective of the gas company is to sell gas. Research the boiler and make sure it is the right one for your application. Gas does not carry the BTUs that oil does, so make sure if you switch you get the best boiler you can afford....efficiency these days is far more important over the long haul than how much you pay for the boiler. If they are offering the boiler for free as they did a few years ago, remember  that nothing is really free.....it usually involves hidden costs or cost spread out over time.

Good luck

Burnham Boiler

I've had the PVG 4 for the last 4 years and so far, no issues. It is a power vent boiler, and so, generates some fan noise. If you go with this unit and an indirect water heater, I suggest you use a Tekmar 356 boiler control. The Argo control that was installed originally sometimes ignores the call for domestic hot water. I'm not saying that Argo contollers are bad, just mine is a bit wonky.



If you can swing it, look into a mod-con boiler.  i would have gone with an NTI if I knew then what I know now. The Burnham PVG line is advertised at 85% efficiency. Most mod-cons can give you 93%+.



Also, and maybe , most important. GET A HEAT LOSS DONE. Most Gas Company sub-contractors ( my experience)  will install exactly the same BTU rated unit as they are replacing. As has been said before, the Gas Company wants to sell gas and they really done care if you go for a mid-efficiency unit.



Educate yourself before making a decision. This website is THE place to ask questions and get answers.

It's On There

It's piggy backed with the SCG. It's 85% AFUE. For the money if I didn't need draft induced I'd be looking at the ES2 instead. That has the IQ control package which allows for a simple plug and play ODR as well as communication ready for Honeywell Red Link products. If you need to have the draft induced boiler I'd wait if I could. The PVG/SCG are getting updated to have the same IQ control and jacket as the ES2. Should see it before the heating season.

dont need draft induced

will check out the es2.thanks for your input.how important is an odr.in my company we are mainly installing steam boilers and atmospheric hydronic boilers.this whole power venting is new to meas are the odr etc.i know im way behind here and from what i see i need a lot of schooling.so would you go with an indirect or a on demand water heater.i do have an operating chimneyand lining it will not be a problem.thanks again

ODR

I would say its important. You only need design water temp on design day. Why make it everyday. General rule of thumb, for every 3 degrees you can run a system below 180 degrees water you can save 1% of fuel. So if you are able to run a curve off 160 vs 180 that's a little over 6% before you turn the boiler on.



Can't stress a room by room heat loss, emitter mesurement and calculation of a workable heating curve enough. Now, here's the problem with the ES2. Price..By the time you add the ODR and LWCO cards as well as line the chimmney your at the price condensing boiler.



If it were my own house I would use an indirect. What is the DHW demand? Where are you located?

Burnham Boiler

Burnham's ES2 is one of their highest efficiency boilers.  Consumers Digest rated it best buy of 2010-2011.  If you are going Burnham go ES2.  make sure they do a load calculation.  you don't want to big of a system or two small of a system.

Free boilers are expensive

seldom are the "free" boilers the most efficient boilers for a given application. Quality Burnham is a good make, they have many models of boilers for different markets.
