    Per the AFII manual the pump pressure is normally set at 140 psi. From personal experience Suntec pumps are not always reliable at pressures nearing 200. Riello pumps are more reliable at those...

    I respectfully disagree with the statement regarding nozzle type. System 2000 with a Beckett burner uses a hollow nozzle. Using the Carlin burner on an EK-1 a hollow nozzle is specified but on the...

    One of the first things I learned when I went into business for myself was to refuse jobs I wasn't qualified to do. The bulk of my work was oil service and installations since I'd been doing that for...

    I can't speak for the cooling side, but on the heat side setting temps back more than a few degrees, maybe 4-5, does not decrease operating costs. As objects in the heated area cool off, they reach a...

    I bought a Garmin several years ago but don't use it enough to be very familiar with it. It does recalculate quickly if I decide to take my own route. A friend has a TomTom that he likes a lot. I...

    Heat purge is accepted under the new mandate and is a good alternative to ODR but it doesn't work well enough on large mass systems. Too much energy would be left in the boiler at the end of a cycle....

    I've been to several trade schools to learn as much as possible about all the equipment that's in the field in my area so I didn't look like a dummy to the customer. If one of those instructors had...

    Sorry. I believe it can be done to an extent with one of Honeywell's packages. Just not sure why you wouldn't just go with the real deal and have a system where everything is made to go together.

    This last post shows that you don't know jack about the EK. Most of the EK's sold in the past 10 years clean from the front so can be installed against a wall. Most non-condensing boilers sold today...

    I'm not sure about lubricity. I believe it's more a case of the seals not holding up. The standard pump seals are good for B20. Webster has a special one for bio thats good to B95.

    Steel tanks are good for up to B100 but at that point the issue is more with the oil lines, filter gaskets, pump seals, etc. If the tank is new no problem with it but if it's an older tank there will...

    My biggest concern with that would be what happens in cold weather and there's no hot water use for awhile due to the folks going on vacation or something like that. Won't the tank overheat? Why not...

    I've only seen the fiberglass tanks at heating shows, never in the field. I don't know of any supply houses in my area that sell them. They are available in single wall and double wall, have UV...

    It doesn't need the special t'stats with feedback, it knows which zone was last active and purges the heat there. The boiler only holds a few gallons of water so when you figure that heat loss from...

    There are three options for oil tanks, none of which is stainless or cast iron. Option 1: galvanized outer tank with plastic inner tank. Option 2: welded steel tank. Option 3: Fiberglass tank.

    The EK purges the heat remaining in the boiler after the last demand is satisfied, whether heat or hot water, to the last zone that was active, It doesn't purge to a random zone or to the same zone...

    Air

    My reply was based on your previous comment about the price of a replacement. The figure you used was blocked but from the way the comment was phrased I figured it was pretty steep.

    Air in system

    Ambizyti, I guess you don't understand the concept of the system post purge. The objective is to put use to the energy that you paid to put in the boiler either for heat or hot water. What better...

    Initial purchase price won't be that much different between the two sizes but, and this can be a big but, the more oversized the boiler is the more burner shortcycling you'll have. That translates to...
